General Information

CHAPTER 1GENERAL INFORMATION

1-1 INTRODUCTION

SenseNETTM is a Windows®-based program that provides central management and monitoringof up to 127 AIR-Intelligence detectors on a fault-tolerant communications loop with extensiveerror checking and correction.

SenseNET is scalable, allowing expansion for larger sites using multiple loops (with up to 127detectors on each loop).

Maps and warning sounds, including spoken messages, may be set for each detector. Detectorsmay be grouped together in zones with an associated zone map, allowing Alarms or Faults tobe quickly and easily located.

SenseNET seamlessly integrates with AIR-Intelligence detectors and allows for futuredevelopments in detection technology.

1-2 FEATURES

SenseNET features include:

• ClassiFire® artificial intelligence (which dynamically adjusts detector sensitivity to matchchanges in the normal environmental smoke density)

• Ability to configure and manage a large detector network centrally with a simple,streamlined interactive graphical user interface

• Device mapping to a graphical user interface

• Real-time alarms with spoken instructions and definable sound files

• Event logging of events to disk in real time

• Automatic detection of all attached devices for rapid site configuration

• Extensive error checking and correction

• Real-time pager or email alerts to compatible GSM mobile phones

• Real-time displays and printing of system status and historical information

• Real-time diagnostics of all networked devices

• Contact Monitors that interface to other manufacturers’ equipment

• Four password-protected levels of security access to system settings

1-3 PC REQUIREMENTS

Minimum computer requirements for the SenseNET are listed below. System requirementsvary between operating systems. Refer to the section below which applies to your computeroperating system.

For computers with Microsoft® Windows XP installed:

• PC with 300 MHz or higher processor clock speed recommended; 233 MHz minimumrequired (single or dual processor system)

• 128 MB of memory (RAM) or higher recommended (64 MB minimum supported; may limitperformance and some features)

For computers with Microsoft® Windows 2000 installed:

P/N 33-308100-006 1-1 June 2009

General Information

• 133 MHz or higher Pentium-compatible CPU

• A minimum of 64 MB of RAM

1-4 ADDITIONAL HARDWARE REQUIREMENTS

• The PC running the SenseNET software needs to be connected to the Command Module onthe detector loop or through a PC Interface (as shown in Figure 1-1 and Figure 1-2).

• A Hayes-compatible modem and dedicated line is required for sending messages to apager. Refer to Section 5-7 for setup information.

1-5 SENSENET ARCHITECTURE

The SenseNET system uses multiple hardware and software layers and installation is greatlysimplified by installing one layer at a time from the bottom layer up. The architecture layers ofa SenseNET system are shown in Figure 1-1.

Figure 1-1. SenseNET Architecture

• Lower layer/Detector: The detector must first be installed according to the providedinstallation instructions and the applicable Design, Installation, Operation, andMaintenance (DIOM) manual. Next, the detector address must be set and there must beno faults indicated before proceeding to the next layer of system set-up. Faults at thisstage, especially detector faults through invalid addressing, may stop the higher layersfrom working correctly.

• Top layer/Remote Display Units and SenseNET‚ PC Interface: Remote Display Unitsmust have their address switches set to the same value as the detector whose display youwish to repeat. A PC running SenseNET software must be set up and connected for use inmonitoring the system. Refer to Section 2-2 for instructions on how to install SenseNETsoftware.

1-6 CONNECTING A SENSENET COMMUNICATION NETWORK LOOP

Detector devices are connected to one another via an RS485 cable. The SenseNET data cableshould be 120Ω shielded (screened) twisted pair such as Belden 9841 24 WG. The total lengthof cable interconnecting a SenseNET system should not exceed 3/4 mile (1.2 kilometers).

If a longer cable run is unavoidable, AIR-Intelligence detectors can be configured using a built-in repeater. This repeater uses an innovative design that adds negligible delay to the RS485signal, unlike conventional RS485 repeaters which will often delay the signal by one byte(character) time at each repeater and limit the number of times the signal may be boosted.

General Information

If full fault tolerance is required, you must connect through a device known as the CommandModule. The Command Module monitors the looped communications bus and signals any loopshort or break. A sample configuration is shown in Figure 1-3.

Figure 1-3. Sample Fault Tolerant Configuration Running SenseNET with a Command Module

Any fault on the loop can be isolated by the Command Module to the loop segment that theproblem actually occurs on and displayed in SenseNET.

The Command Module also gives common Alarm and Fault notification for all detectors on theloop so that relay outputs on the Command Module can be connected directly to the Fire Panel.

General Information

1-7 CONNECTING TO THIRD-PARTY SYSTEMS

Other monitoring devices, such as a Building Management System (BMS), connect to a secondRS232 port on the Command Module. Current BMS protocols supported are BACnet ptp andASCII output (as shown in Figure 1-3).

1-8 MONITORING THIRD-PARTY DETECTORS THROUGH SENSENET

You can monitor third-party detectors through SenseNET using the Contact Monitor. TheContact Monitor interface allows four Alarm levels, Fault, and two additional inputs.

This feature is used to monitor older or noncompatible aspirating detectors when adding AIR-Intelligence detectors to an existing system.

1-9 REMOTE DISPLAY UNITS

Remote Display Units (RDUs) can be connected at any point on the bus, set to the sameaddress as the AIR-Intelligence detector whose display is to be repeated or displayed. Alarm,Fault, and bargraph levels are shown on the front panel of the RDU.

An RDU is a 19-inch rack-mounting unit which may be stacked into rows of eight at a time ona rack to display a large number of detectors in a control room.

In normal operation, all connected bus devices are monitored by SenseNET. When a devicefails, the Alarm/Fault Viewer automatically displays, indicating the device address and thenature of the failure.

If the PC on which SenseNET is running stops receiving data from the bus, which can happenif the RS232 cable breaks or becomes disconnected, the message “Communications Fail” isdisplayed automatically after a period of time (which is set at the factory).

Figure 1-4. Remote Display Unit Front Panel

P/N 33-308100-006 1-5 June 2009

General Information

The address switch on the RDU Card should be set to the same address as the AIR-Intelligencedetector whose display is to be repeated. (See Appendix B for a list of valid addresses.)

If no bus master or PC is to be used on the system, then set switch 8 to the ON position to getthe RDU to poll the detector. If multiple RDUs are used, only one RDU must be set to poll.

The RDU requires a 24 VDC power supply and is designed to be fitted into a 19-inch rack frame.

1-9.1 The Remote Display Unit Relay Board

The optional relay board provides separate relay outputs for all alarm levels from eachAIR-Intelligence detector driving a particular RDU.

Once the relay board is connected to the RDU (which must be powered off first), operation iscompletely automatic.

Relay contacts are provided for each alarm level, plus a normally energized common faultrelay.

1-9.2 Using a Remote Display Unit to Show Common Detector Status

Setting an RDU to address 0 will configure it to display the common alarm and fault status forall detectors when a Command Module is used in the network. No bargraph indication will beshown when the RDU is set to the common address.

If a relay board is fitted to an RDU set to address 0, then the relays will indicate common alarmand fault relays for all detectors.

This signal is sent from the Command Module, and is only available when a hardware commandmodule is used.

1-10 POWER SUPPLIES

The PC interface has its own internal power supply, which provides 24 Volts DC for the unit. Ifcomplete uninterruptable operation is required, the PC and SenseNET PC Interface should bepowered from an Uninterruptable Power Supply (UPS).

The power requirement for the RDU is 40mA max at 24 Volts.

2-3 PASSWORDS

Use the Passwords option to set the four different levels of password access to SenseNET.

The four levels of access listed in order of most restricted to least restricted are:

• Read only

• Operator

• Engineer

• Administrator

The access levels work so that a higher access level has all the privileges of the levels below itplus the unique access privileges for that level. For example, Engineer access has Operator andEngineer privileges.

Use the Passwords option to set the four different levels of password access to SenseNET.Table 2-1 shows the privileges assigned for each of the four access levels.

4. Select <OK>.

Note: When SenseNET is first installed, no passwords are set. Not entering any passwordallows access to all four access levels. After initial start-up, you must set accountpasswords.

2-4 CONNECTING THE DETECTOR OR COMMAND MODULE TO AN RS232 SERIAL PORT

Connect the PC to a Detector or Command Module with an RS232 serial port cable with twofemale 9-pin “D” connectors wired (see Figure 2-8).

Figure 2-8. RS232 Serial Port Connection

In a network of Detectors connected to a common Command Module, the remote softwareallows centralized access to interrogate or program any Detector or the Command Module inthe network loop from a common location. You do not need to remove and reconnect theRS232 cable to different Detectors.

WARNING

Boot up the computer before connecting the serial cable to the Detector, asotherwise it may “recognize” the Detector as an added serial mouse or anotherpiece of peripheral equipment.

June 2009 2-6 P/N 33-308100-006


When connecting to an individual Detector in a network loop rather than to the CommandModule, SenseNET generates a “Comms fault” at the Command Module. This is normal,because the Detector’s RS485 communications are overridden by the RS232 communications.

2-5 SETTING UP THE COMMUNICATIONS

SenseNET allows up to 16 loops to be managed simultaneously, each with 127 devicesattached. These loops may be local (connected to COM ports on the PC running SenseNET) orremote (accessed through a network connection). A network port can connect to either asingle loop of another PC running SenseNET or a Micro Serial Server (MSS).

SenseNET supports up to 127 detectors plus a Command Module on a loop. With a maximumof 16 loops, this allows up to 2032 detectors to be monitored.

Selecting Communication settings from the Options menu presents the Communicationsettings dialog box (see Figure 2-9). A COM port (for a local connection to detectors) or anetwork port (for remote connection) may be selected in this menu.

Figure 2-9. Communication Settings Dialog Box

• Port:

– Loop (drop-down box): Selects the loop which is being configured.

– Com Port (drop-down box): Selects the communications port (COM1 or COM2).Figure 2-9 shows “COM1” as the selected port which means that this loop is a localport. “COM2” should be selected when connected to the COM2 port on the PC.

• Buffer Sizes: Sets input (Receive) and output (Transmit) buffer sizes (which are notusually used).

• CTS enabled: This checkbox should only be checked when connected to CommandModules.

• Monitor from network: This checkbox should be checked if the PC on which SenseNETresides will be monitored by a remote PC also running SenseNET.

• Number of loops: Sets the number of network loops being used. In the example providedin Figure 2-9, the detector network is composed of a single loop.

• Port type: Sets the port type to one of the following:

P/N 33-308100-006 2-7 June 2009


– COM port: local port

– Network monitor: allows you to set up local and remote communications usingmultiple PCs (See Section 2-5.1 for details).

– Network control: allows you to set up local and remote communications usingmultiple PCs (See Section 2-5.1 for details).

– VESDA HLI: Allows the PC on which SenseNET software resides to monitor orcontrol a VESDA®netTM network using the Vesda Open Protocol HLITM (model VHX-0300). (See Section 2-5.2 for details.)

2-5.1 Setting Up Local and Remote Communications Using Multiple PCs

If you want to configure your site setup for local or remote communications using multiple PCs(either a remote PC or MSS server), set the Port type drop-down menu to either of thefollowing:

• Network monitor

• Network control

When you select a remote port of either of these types, the Port value changes (as shown inFigure 2-10).

Figure 2-10. Communication Settings Port Area Alternate Display (Network Monitor and Control)

• Computer/address: Set to either the computer name or IP address of the remote PC orMSS. In the example shown in Figure 2-10, the address is set to IP address 200.20.1.90.

• Loop: Set to the loop to be monitored on the remote PC. In the example shown inFigure 2-10, the loop value is set to “loop 1.” If the loop to be monitored is an MSS unit,set the Loop value to 1.

2-5.2 Setting Up Local and Remote Communications to Monitor a VESDAnet Network

If you want to configure your site setup for local or remote communications using VESDA OpenProtocol HLI to monitor a VESDAnet network, set the Port drop-down menu to “VESDA HLI.”

When you select VESDA HLI as the port type, “Network ID” replaces “Loop” as the valuedisplayed for the item Port (see Figure 2-11). Network ID is set to 0.

2-5.3 Sample Network Configuration

The sample SenseNET network configuration shown in Figure 2-12 shows how SenseNET canuse a network connection instead of a COM port for monitoring or controlling a loop.

The sample network configuration shown in Figure 2-12 contains three PCs running SenseNET:

• Computer “PC1” is monitoring a Micro Serial Server (MSS) which is connected via RS485to a Command Module monitoring up to 127 AIR-Intelligence detectors. This type ofconnection allows monitoring only (Port Type is set to “Network monitor”). Loop is set tothe loop which will be monitored by the remote PC. In this case, it is set to “1” (as shownin Figure 2-13). When monitoring a MSS unit, the Loop must be set to “1.” The TCP/IPaddress of this MSS is fixed at 200.20.1.70 (so this is used as the computer/address.)

Site Configuration

CHAPTER 3SITE CONFIGURATION

3-1 INTRODUCTION

SenseNETTM has been designed to simplify configuration, monitoring, and management of anysite with two or more detectors. SenseNET is capable of managing up to 16 loops of 127detectors for one PC graphic system. SenseNET uses an auto-discover mode called SiteScan™.to locate all connected bus devices and reads their configuration settings (which includes thedevice information), making the process quick and less prone to error.

The following steps will create a new site that reflects the hardware setup:

1. To set up SenseNET for a site, all detectors must be attached to the bus and each detectormust have a unique address (as explained in the pertinent detector manual).

2. From the main menu, select File>New site to create a new site and provide a descriptivefile name for the site when prompted.

3. SenseNET prompts you to ensure all detectors are powered up. Select <Yes> to continuewhen ready.

4. The bus is scanned for all detectors and their current function settings are saved to disk.This process may take several minutes but only has to be done once.

Note: Detector addresses do not need to be contiguous—which means that there can be gapsin the address range.

5. The Site Configuration Editor is displayed. If no site maps or actions are required, thenthe set-up is complete. Proceed to step 7.

6. Use the Site Configuration Editor to set up detector maps, alarm/fault actions, andzones (see Section 3-2.1 for details).

7. Close the Site Configuration Editor. The bargraph displays are updated to show the newsite configuration.

The new site will now automatically be loaded each time SenseNET is started.

3-1.1 Configuring a Basic Network

For a simple installation, this may be all that is required to set up a site. The SiteConfiguration Editor has a simplified mode that allows only the functions shown, in order tominimize complexity (see Figure 3-1).

Site Configuration

3-1.2 Remote Configuration Software

SenseNET also includes features from the Remote Configuration Software program (suppliedwith every AIR-Intelligence detector) that augment commissioning and maintenance. TheRemote Configuration Software program allows you to configure and monitor programmablefunctions for the detectors and the Command Module from a desktop computer or PC.

Using the Remote Configuration Software program, a detector can be programmed directlyfrom within SenseNET. Typical programming settings set the time and date, change alarmlevels, and control how the detector responds to an alarm threshold being reached.

Groups of detectors can also be simultaneously set using the Remote Configuration Softwareprogram. A typical example would be synchronizing the time and date held in all detectors.

The Remote Configuration Software program enables the user to configure the followingaspects of detectors and Command Modules:

• Device settings

• Communications settings

• Global Reset of devices

• Status displays

The Remote Configuration Software program also allows you to display the following types ofstatus information for the networked detectors and Command Module:

• Communications bus

• Diagnostics

• Chart recordings

• Event logs

• ClassiFire histogram

Refer to the AIR-Intelligence Remote Configuration Software User’s Guide (P/N 33-308100-004) for details.

3-2 MANAGING YOUR SITE CONFIGURATION

b. Add the appropriate device.

c. Select File>Save function settings from the main menu to transfer the currentfunction settings of the new detector to the site configuration file.

3-2.5 Critical Fault Setup

The SenseNET system allows faults to be allocated either “critical” or “non-critical” status. Thecritical fault selection dialog (see Figure 3-6) is displayed by selecting the <Faults> button inthe Site Configuration Editor. It determines whether individual faults on the currently-selected detector are critical or non-critical.

• Selecting a box means that this fault is a critical fault, and when it occurs, the critical faultaction text and sound is used in the alarm viewer.

• Clearing a box means that the noncritical fault actions are used in the alarm viewer. Whena detector is first defined, all of its faults are set to be critical faults by default.

Figure 3-6. Critical Faults Screen

3-2.6 Alarms and Event Sound and Text Feature

One important feature of SenseNET is that specific text and/or sound files (which may includespoken directions) can be displayed or played upon the occurrence of specific events such asAlarms or Faults (see Figure 3-7). These may be unique to each detector. (See Section 5-12for details.)

P/N 33-308100-006 3-7 June 2009

Site Configuration

Figure 3-7. Alarm and Fault Speech and Text Files

The text shown when events occur can also be sent to a pager (or compatible GSM phone usinga modem) or via E-mail if the PC running SenseNET is connected to a network. This allows sitepersonnel to react quickly to service requests (such as failing standby batteries).

3-2.7 Setting Device and Zone Maps

The SenseNET system can store site maps of protected areas in which one or more devices arebeing used. When an alarm occurs, these maps may be viewed to show all detectors in a zone,helping to pinpoint the area of danger.

SenseNET site maps are standard Windows bitmap (.bmp) files that are created in an imageeditor program capable of creating .bmp files. Maps are scaled to fit the display window.Display of 24-bit bitmaps is not supported. Individual site maps can be set for any device inthe site list (command Modules, detectors, and power supplies).

The Read button provides real-time information on the selected detector’s laser chamberoutput as a percentage of full-scale output (not a direct measure of smoke obscuration) andthe flow for each aspirating pipe (see Figure 4-9).

• For an ASD-160H detector: Only a single flow reading would be present.

• For an ASD-320 detector: There would be either 1 or 2 pipes.

Flow readings are only taken from a pipe when the relevant pipe’s flow sensor is disabled (SeeSection 5-2.2 for details on Programmable Functions.)

In normal operation, the flow readings read between 55-70%. Regardless of the pipe layoutused, the flow reading is set to this level during initial power-up. Figure 4-9 shows sampleresults.

Although it is continually updated in the Detector, the chart recording on the PC represents asnapshot of the Detector’s status at the time the chart was downloaded.

4-3.4.1 CHART RECORDING KEY FEATURES

Key features of the Chart Recording screen are called out in Figure 4-11:

June 2009 4-12 P/N 33-308100-006


3. Mouse pointer: Points to the time period for the data reported in the Chart Informationscreen.

4. Detector Output and Alarm Level: The Detector output (called out in Figure 4-11 as “4”)is stable, while the alarm level (called out in Figure 4-11 as “5”) is rising. This indicatesthat the ambient smoke level is low and steady.

The expected output level of the Detector in absolutely clean air is in the range of 9-11%.

Readings above the “clean air” range are common in normal working environments, and thealarm level will adjust itself to the normal ambient level of pollution in the protected area.

The falling alarm trace coupled with a steady output indicates that the Detector is undergoingthe 24-hour learning period following a FastLearnTM. When the Detector output level tracemeets or climbs above the alarm level, a fire alarm is generated.

The chart recording can be used to gauge the appropriateness of the ClassiFire® alarm factorto the protected area. (See Appendix D for further details.) Where the background pollutionlevel is steady (such as an electronics cleanroom), the installer may choose a low alarm factor.If, however, the chart recording shows large variations in background level, which oftenapproach the alarm level, the installer may decide to set a higher alarm factor to avoidnuisance alarms (See Section 5-2.2.4 in Chapter 3 for details on how to set the alarm factor).

4-3.4.2 CHART RECORDING SCROLL BARS

The scroll bars at the bottom of the Chart Recording screen allow you to scroll backwardsand forwards through the chart recording to see areas of the chart which are off-screen.

The actual time duration captured in a full chart recording depends on the recording ratechosen, a smaller time period between divisions resulting in a more detailed chart of shorteroverall time span. When the overall chart period is exceeded, the earlier readings arediscarded.

Chart Recording can hold 2000 samples with 10 samples to a division.

For example, a chart recording with a 10-second per division recording rate would cover amaximum time period of about 5 hours, 15 minutes.

A 20-minute recording rate would capture a period of 2 days, 19 hours.

Figure 4-18. Sample Histograph Screen with Alarm Factor “0”

Unlike the chart recording, the histogram updates in real time, showing the response of thedetector to smoke tests. The smoke histogram is shown to the left of the labeled fire flags. Ina relatively clean or stable area, the histogram should be narrow, consisting of only a few barsas shown Figure 4-18.

The histogram is in two parts:

• A blue “fast” histogram shows the current smoke distribution. The blue histogram coversa period of the last 15 minutes, and is responsible for generating fire alarms.

• A yellow “slow” histogram reacts far more slowly than the blue histogram. The bluehistogram is responsible for positioning of the fire alarm flags, based on the long-termvariation in smoke density and the chosen ClassiFire alarm factor.

As smoke is introduced, the fast histogram, shown in blue, will begin to move to the right ofthe screen, and the detector output level shown at the bottom of the screen will begin toincrease. When the histogram crosses one of the alarm flags, the detector will generate thatalarm.

In the example shown in Figure 4-18, the Pre-Alarm, Fire 1, and AUX alarm flags are closetogether due to the chosen alarm factor of 0 (very high sensitivity). The Fire 2 alarm flag is

Table 4-13. Relatively and Absolutely Scaled Definitions

Relatively/Absolutely Definition

Relatively Scaled(yellow portion of the scale)

The absolute value of a reading on the relatively scaled yellow portion of thebargraph will depend upon the ClassiFire Alarm f factor chosen, and the level ofambient pollution that the detector has accepted as a normal background level aspart of the ClassiFire learning routine. In normal conditions, the yellow bargraphdoes not show any indication, so that the bargraph is an indicator of abnormalconditions only.

Absolutely Scaled(red portion of the scale)

A reading on the red portion of the bargraph (Fire 2 bargraph) does not depend onthe ClassiFire alarm factor. It is a direct numerical measure of the concentration ofsmoke seen at the detector in terms of % obscuration/meter. Theoretically, if the“learned” background smoke level was very high and the detector was set to veryinsensitive, the detector could display a reading on the red Fire 2 bargraph before itshowed anything on the relatively-scaled yellow Pre-Alarm/Fire 1/Aux bargraph.

Event logging on SenseNET is extremely flexible—generated events are stored in thedetectors even when the PC is powered off or SenseNET is not running.

An event log may be read from a detector or group of detectors and a filter applied to theevents to show, for example, all alarms or a certain type of fault only, ensuring that onlyrelevant event information is shown.

Figure 4-30. Event Filter Screen

Event logs may be saved to disk for later recall or printed at any time. In addition to the storageof events in a detector, SenseNET stores all events to a log file on disk as they occur. The sizeof this log file is limited only by hard disk space. Also stored in this log are all user inputs thatchange the state of SenseNET such as changes in access levels or device resets.

The first screen of the Function settings module is the Device information page shown inFigure 5-2 and described in Table 5-1:

It is probably most useful to set the device text for a detector to the name of the area beingprotected, e.g., “Computer room,” “Stores,” etc. When this text string appears in the DeviceInformation screen, SenseNET software is communicating properly with the detector.

To access the sub-pages for a device type, select the tabs at the top of the screen. All sub-pages in the Function settings module have common function settings at the bottom of thescreen (see Figure 5-5):

Figure 5-5. Common Settings for Device Setting Sub-pages

Table 5-1. Device Information Screen Options

Option Function

Device type The type of detector or Command Module.

Firmware version Revision number of the main software chip within the device.

Watchdog count

Each unit contains a “watchdog,” which detects momentary interruptions to the power supplyto the unit. If this is above 0, it may indicate a problem in the power supply or wiring. Awatchdog trip generates a fault condition, so the times and dates of watchdog faults can beseen in the detector’s event log.

Run-time hoursThe length of time in hours that the unit has been running since initial power-up. It is notreset by powering down the unit, but may be reset by removing and replacing a detector’smemory reset link.

Device textCan be edited to any alphanumeric text of 16 characters or less. In the case of a unit withLCD display, it is the default legend displayed on the LCD panel when the unit is operatingnormally. It is also displayed on a connected Command Module in the case of alarm or fault.

P/N 33-308100-006 5-3 June 2009


The drop-down box on the left allows selection of the unit to which the programmable functionswill apply. The very top of the list reads “Command Module,” and the rest of the list runs from“Detector 001” to “Detector 127” to allow you to select the settings for any detector in thenetwork.

Use the options at the bottom of the screen to perform various functions as shown in Table 5-2:

5-2.2 Device Setting Functions

You can modify the Device Setting functions for each device. Note that not all device settingsare applicable to each device. For example, Pager device setting only applies to theCommand Module, and not the other AIR-Intelligence detectors.

The following sections describe the functions accessible through the Device Settings tabs.

5-2.2.1 MATRIXSCAN

The MatrixScan device settings apply only to Command Modules.

MatrixScan allows you to set up “virtual detectors.” If the sampling pipework of two detectorsshares a common location (for example, two detectors have sampling holes in the same area),these detectors can be assigned a “virtual” detector number.

This virtual detector generates an alarm at the Command Module when both “real” detectorspick up smoke at the same time. Therefore, with only two detectors, zone localization isavailable from a large number of protected areas.

The “virtual” detectors are assigned in the MatrixScan screen (see Figure 5-6).

Table 5-2. Common Device Settings for Device Setting Sub-Pages

Option Function

<OK>

Sends all modified settings to the selected detector and closes the Function Settingsscreen. Select this when you have completed changing settings.

If <Save All> is selected, clicking <OK> sends all modified settings to all detectors,where that function is applicable to the detector.

Note: Command Module function settings need to be performed separately.

Modified(checkbox)

If you select the Modified checkbox, it means that only settings which have beenmodified will be sent to the detector(s). Clearing the checkbox sends all programmablefunctions applicable to the current detector to all other detectors on the loop.

If you wish to set up all detectors on the loop to have identical settings (regardless of theircurrent settings), change any settings that you wish to apply, select Save All, de-selectthe Modified checkbox and click <OK>. All detectors will then be set to identicalparameters.

<Cancel> Exits the Function Settings module without saving any changes.

Figure 5-6. MatrixScan Screen

In the example shown in Figure 5-6, detector address 1 has common sampling locations withdetectors 2 and 3, and detector 2 also has a common sampling location with detector 4.

The MatrixScan screen contains the following checkboxes:

15 “real” detectors can be used in a MatrixScan network, leaving 105 possible “virtual”detectors.

The MatrixScan screen limits the choice of detector address as follows:

• Real detectors are assigned addresses in the range 001-015

• Virtual detector addresses are assigned in the range 016 to 105. Real detector addressesin this range will clash with the virtual detector addresses, causing problems. However,unused virtual addresses may be used for other real detectors which are not part of theMatrixScan network.

Note: Address 000 is reserved for a network’s Command Module, and cannot be used for adetector.

Table 5-3. MatrixScan Screen Checkboxes

Checkbox Function

Enable Enables virtual detectors when the box is selected, as shown in Figure 5-6.

Base address The address of the lowest-numbered real detector in the loop. In Figure 5-6, the baseaddress is “001.” The MatrixScan function requires that you enter a base address.

All cells and No cells Respectively, selects and clears all the cells.

P/N 33-308100-006 5-5 June 2009


The number of virtual detectors available for a given number of real detectorsusing MatrixScan can be calculated by the following formula:

Figure 5-7. Number of Possible Virtual Detectors for All Available Real Detectors.

Table 5-4 shows maximum numbers of virtual detectors produced by using the above formulawith values of real detectors from 2 to 15. Fifteen is the limit of real detectors in a system usingMatrixScan, due to the fact that 105 virtual detectors + 15 real detectors is 120 detectoraddresses, and the maximum number of addresses available on a single network loop is 127.

5-2.2.2 ALARM ACTIONS

The Alarm Actions device settings only apply to detectors and Command Modules.

5-2.2.2.1 Remote Input Functions

The Remote Input functions allow various functions to be carried out manually by shortingthe relevant remote inputs in the unit (for example, by using a key switch or relay). Noelectrical power should be applied to the inputs.

The ASD-640 detector and Command Module have three dedicated remote inputs, marked “I/P 1” to “I/P 3”.

The standard ASD-160H detector does not have remote inputs, but you can fit an add-on relay/input card to it, which provides this remote input functionality. On the ASD-160H detector, thesame inputs are assigned as 1, 2 and 3.

An add-on card can also be added to the ASD-640 detector, providing three additional remoteinputs, which are assigned as remote input numbers 4, 5, and 6.

The Remote input box contains checkboxes which enable the functions. To the left of thecheckboxes are numerical input boxes, which accept values in the range 1 to 3 (ASD-160H orASD-320), or 1 to 6 (ASD-640) with relay/input card fitted. This number corresponds to therelevant input terminals on the detector unit. “1” corresponds to input “I/P 1” on the unit, “2”corresponds to input I/P 2,” and so on.

Note: The same input number cannot be used more than once, to ensure that the deviceshave unique input numbers.

5-2.2.2.2 Function Settings Checkboxes

The Alarm Actions Function Settings screen contains the following checkboxes:

P/N 33-308100-006 5-7 June 2009


Table 5-5. Alarm Actions Function Settings Screen Checkboxes

Checkbox Function

Remote IsolateWhen used on a Command Module, Remote Isolate disables the Command Module relays, but does not disable detector communications. On a detector, the unit is effectively removed from the communications loop.

Remote Reset Resets latching alarms and fault LEDs, relays, and LCD display messages.

Remote day/night

Only applies to detectors. Shorting the selected input terminal toggles the detector between day /night setting. This is useful, for example, when working hours in an area are irregular. The remote day/night could be activated when the last person leaves the area.

Remote day/night overrides any timed day/night settings set in the Day/night switching panel of the Remote Configuration Software, which means that the detector will only switch between day and night settings when commanded on the remote input, regardless of any preset switch-over time.

Programmed Isolate

When selected, Programmed Isolate prevents the detector from sending anyalarm or fault condition to a connected fire panel. The “Fault” LED will light on thedetector front panel while it is isolated.

You can use the Programmed Isolate function to prevent unwanted alarms orfaults during testing, maintenance or repair.

The Programmed Isolate function automatically disables itself after 7 days if ithas not been manually disabled.

WARNING

When applied to a Command Module, the Programmed Isolate function disablesthe Command Module fire and fault relays, but does not disable any APICcommunications. The function differs from the front panel isolate in that pressingthe enabled <ISOL> button generates a fault at the panel, whereas ProgrammedIsolate does not. For this reason, Programmed Isolate must be used carefullyand disabled as soon as possible. Failure to disable the Programmed Isolatecould impact the functionality of the unit, potentially resulting in propertydamage or personal injury.

Latching alarms

When cleared (disabled), any alarm condition will clear itself when the firecondition ends. When checked (enabled), the alarm condition persists until thedetector or Command Module is reset, either from the detector front LCD panel (iffitted), from the Command Module front panel, or from the remote software.

Note: A reset from the front panel requires that the <RESET> button be enabled;the button is disabled by default.

In units fitted with an LCD (ASD-640 Standard Detector, Command Module),latching alarms are enabled by default. In units without an LCD (ASD-160H andASD-320), latching alarms are disabled by default.

CAUTION

If latching alarms are disabled at the detector but enabled at the CommandModule, then any alarm condition still requires a Command Module reset to clearthe alarm from the fire panel.

Latching faults

When cleared (disabled), any fault condition clears itself when the fault condition ends. When selected (enabled), the fault condition persists until the detector or Command Module is reset, either from the detector front LCD panel (if available), from the Command Module front panel, or from the SenseNET software.

CAUTION

A reset from the front panel requires that the <RESET> button be enabled; thebutton is disabled by default for all units. If latching faults are disabled at thedetector but enabled at the Command Module, then any fault condition will stillneed a Command Module reset to clear the fault from the fire panel.

5-2.2.3 TIME AND DATE

The Time and Date device settings apply to detectors and Command Modules.

Figure 5-9 shows the Time and Date function settings screen for a Detector device (“Detector001”).

Figure 5-9. Time and Date Function Settings Screen

This is the time and date to be used for the unit’s internal Real Time Clock, and is used in eventlogs and chart recordings.

The Time and Date function does not automatically update for Daylight Savings Time or otherchanges of local time. You must update the Real Time Clock settings periodically, or you mustmake allowances for the time difference when reviewing data.

Note: When installing a detector, the clock may need to be set to correct local time.

The date and time can be set by one of the following methods:

• Incrementing or decrementing each value (hours, minutes, day, month, or year) byclicking the up or down arrows to the right of each display box

• Select one of the boxes to highlight it and type in the relevant value

• Select the <Set from PC> button to synchronize the detector’s clock with the current timeand date set on the controlling PC.

Cascading alarmsWhen cleared (disabled), the detector starts to count down the Fire 1 alarm delay once it has generated a Pre-Alarm and Fire 1 alarm delays are cumulative. The Cascading alarms function is enabled by default.

5-2.2.4 ALARM LEVELS AND DELAYS

The Alarm Levels and Delays device settings apply only to detectors and not to CommandModules.

Figure 5-10 shows the Alarm Levels and Delays function settings screen for a Detectordevice (“Detector 001”).

Figure 5-10. Alarm Levels and Delays Function Settings Screen

For each of the detector’s fire alarm levels (Pre-Alarm, Fire 1, Fire 2, and AUX) there arenumerical boxes for Level and Delay:

5-2.2.4.1 Level

(For Pre-Alarm, Fire 1 and AUX) Corresponds to the relatively-scaled level that needs to bereached on the detector’s bar graph display (if fitted) or on an attached Command Module orRemote Display Unit’s bargraph display. The Fire 2 alarm level is in terms of absolutely scaled% obscuration/meter from 1% to 25%.

June 2009 5-10 P/N 33-308100-006


Figure 5-11 shows a bargraph display from an ASD-640 detector to illustrate the concept.

Figure 5-11. Bargraph Display from an ASD-640 Detector

– Relatively Scaled (yellow portion of the scale): The absolute value of a reading onthe relatively scaled yellow portion of the bargraph will depend upon the ClassiFire®

Alarm factor chosen, and the level of ambient pollution that the detector hasaccepted as a normal background level as part of the ClassiFire learning routine. Innormal conditions, the yellow bargraph does not show any indication, so that thebargraph is an indicator of abnormal conditions only.

You can set the relatively scaled alarm levels to the following range of bargraphlevels:

• Pre-Alarm: 3-8 (default 6). Pre-Alarm always appears before the main Fire1 alarm

• Fire 1: 8-10 (default 8). Pre-Alarm and Fire 1 can be set to the same levelif particularly early warning is not required.

• Aux: 2-10 (default 10). The Aux level may be set below Pre-Alarm for veryearly warning, or above Fire 1 for a high-level alarm confirmation.

– Absolutely Scaled (red portion of the scale): A reading on the red portion of thebargraph (Fire 2 bargraph) does not depend on the ClassiFire alarm factor. It is adirect numerical measure of the concentration of smoke seen at the detector interms of % obscuration/meter. Theoretically, if the “learned” background smokelevel was very high and the detector was set very insensitive, the detector coulddisplay a reading on the red Fire 2 bargraph before it showed anything on therelatively scaled yellow Pre-Alarm/Fire 1/AUX bargraph.

5-2.2.4.2 Delay

This is the time in seconds that a detector needs to continuously sense a given alarm levelbefore an alarm warning is given. The acceptable range is 0 through 90 seconds. This is usefulin an area which generates a lot of smoke “spikes” as a part of normal working (for example,a furnace which releases smoke when the door is opened). In very clean areas, the installermay decide that the delay can be set to 0.

Absolute level(1-25% obs/ m)

P/N 33-308100-006 5-11 June 2009


5-2.2.4.3 Alarm Factor

The ClassiFire system statistically analyzes the background smoke level and sets detectorsensitivity to a level giving a statistical probability of nuisance alarm. The software assessesthe arithmetic mean and variance (standard deviation) of the “normal” ambient smoke leveland places the alarm flags at a certain number of standard deviations from the mean of thedistribution.

The number of standard deviations at which the alarm flag is set away from the mean isdirectly proportional to the ClassiFire Alarm factor chosen.

The probability of nuisance alarm and the maximum detector sensitivity are higher whena low level of alarm factor is chosen and lower as the alarm factor is increased. A low alarmfactor, equating to very high sensitivity, may be desirable in the case of, for example, ahigh-value computer center, or other application where the cost of down-time and call-outcosts may be offset by the high value of the protected installation.

On the other hand, this will not be desirable in an environment with very variable levels ofbackground smoke. In this case, it may be more important to ensure that an elevated levelof smoke really does indicate an incipient fire before alarms are raised.

In summary, a low alarm factor equates to high sensitivity and higher probability ofnuisance alarm, and a high alarm factor gives a lower maximum sensitivity andcorrespondingly reduced probability of nuisance alarm.

The probability of nuisance alarm for a given environment also depends on the “stability”of the background smoke level. For example, a semiconductor clean room may have astrictly-controlled environment so that it is unlikely that smoke level will vary by chance.Under these circumstances, a low alarm factor may not imply a radically increasedprobability of nuisance alarm.

The detector sensitivity is set by entering a value of 0 through 18 into the Alarm factornumerical box. The default is set to 4. Refer to Table 5-6 for suggested settings.

5-2.2.4.4 ClassiFire override

There may be occasions on which a sudden increase in smoke does not necessarily indicate afire condition. Examples are the release of incense during a church mass and the opening of afurnace door in a factory. Under these kinds of circumstance it is not desirable for the detectorto generate a fire alarm.

ClassiFire Override will desensitize the detector by a specified amount when a pair of remotecontacts are shorted. In the case of a furnace door being opened, this could be performedautomatically by an interlock switch on the door, or it could be achieved with a simple on/offswitch. Where the smoke-generating event has a definite length and time of occurrence, theevent could be on a time switch. All that is required is that the relevant input terminals on thedetector are shorted together.

The figure entered into the ClassiFire Override box is the percentage of full-scale detectoroutput by which the alarm flags will be shifted when the contacts are shorted. For example, ifset to a value of 35%, a detector with an alarm level of 20% would have this changed to 55%when the function was activated.

On the ASD-160H or ASD-320 detector, ClassiFire Override may only be used when thedetector is fitted with an optional relay/input card, and the function is reserved for Input 3 onthe card.

On the ASD-640 detector, the default ClassiFire Override contacts are the “I/P 3” terminalsinside the detector.

As a special case, however, when the ASD-640 detector is fitted with an APIC card whichincludes remote input terminals, ClassiFire Override can be set to use one of the remoteterminals on the APIC card by entering a value into the ClassiFire Override box of over100%. ClassiFire Override values of 001 – 099% act on the default input terminal 3, but avalue of 120% would give an override percentage of 20% on APIC card input 1 (if resent),227% would give an override percentage of 27% on APIC card input 2, and so on.

5-2.2.4.5 LDDTM enable

LDD stands for “Laser Dust Discrimination.” This function is enabled by default and it causesthe detector to ignore brief, isolated increases in detector output such as spurious readingsfrom ambient dust particles. In very clean areas, such as semiconductor clean rooms, it maybe disabled to gain a small improvement in response time.

5-2.2.4.6 FastLearnTM enable

If the detector is in FastLearn mode when the screen is opened, this function will be selected(enabled). If cleared (disabled), then selecting this box will start a FastLearn. In a similarmanner, clearing the box stops a FastLearn that is currently in progress.

Note: Stopping a FastLearn operation will prevent the detector from reaching its optimumsensitivity. The detector must be put through another FastLearn cycle and left for 24 hoursto regain full sensitivity.

5-2.2.4.7 Auto FastLearn enable

When selected (enabled), this function starts a new FastLearn sequence each time the detectoris powered down and re-started. This is the default setting, and it ensures that the detector isset to the optimum sensitivity if it is moved to another location. However, if the detector is leftin the same location and powered down, (for example, for maintenance purposes) the functioncan be cleared so that the detector sensitivity is unchanged when the detector is powered upagain.

5-2.2.4.8 ClassiFire 3D

When selected, this feature assesses the rate of increase of smoke in the protected area. Whenthe level of smoke rises too quickly, ClassiFire will ignore any time delays before generating

P/N 33-308100-006 5-13 June 2009


alarms. This means that fire damage is minimized if a fire starts when long alarm delays areset.

5-2.2.4.9 Demo mode

In normal use, the detector carries out a 15-minute FastLearn operation, during which time itcannot signal a fire alarm. It then takes a further 24 hours to reach full operational sensitivity.

Demonstration (Demo) Mode causes the detector to estimate its final sensitivity as soon asFastLearn is finished (omitting the 24-hour learning period), so that smoke response testingmay be carried out as part of detector commissioning. Checking this box only starts DemoMode if the unit is in FastLearn. It has no effect at any other time.

Note: The detector sensitivity will not be set to its optimum level in Demo Mode. The detectormust be put through another FastLearn cycle and left for 24 hours to regain fullsensitivity after testing in Demo Mode.

Flow rate

The current airflow rate for each sampling pipe.

Note: The flow figure is not an absolute measure of airflow. It is automatically set upon initial power-up of the unit so that it can take account of the “normal” flowpresent in the sampling pipe network. This “normal” airflow is then set to readin the region of 55 to 75% to give adequate “headroom” for the flow sensors toregister blocked or broken sampling pipes, regardless of the flow restriction inthe pipe network.

Enable sensorThis feature is only available on the ASD-640. Clearing the box disables the relevant flow sensor. On a system utilizing less than four pipes, it is recommended that the flow sensors be disabled for the unused pipes.

Aspirator (fan) speed

This feature is only available on the ASD-640 detector. This may be reduced to lessen fan noise and power consumption, or increased to improve smoke response time.

Note: Care should be taken that any reduction in fan speed does not increase detectorresponse time outside the limits imposed by NFPA standards or other applicablecodes or standards.

For example, NFPA requires a worst case smoke response time of 120 seconds. Aspirator speed should not be set outside the limits required by relevant legislation.

The Front Panel device settings apply only to units with an integral LCD front panel. TheASD-640 Standard detector and the Command Module have integral LCD front panels.

Figure 5-14 shows the Front Panel function settings screen for a Detector device (“Detector001”).

Table 5-8. Power Monitoring Function Settings

Setting Function

Auto power save

When selected (enabled), the detector reduces fan speed to a minimum, regardlessof preset aspirator speed, when an attached power supply fails. This reduces currentdraw, in order to increase battery life. Any increase of smoke above three bargraphsegments on the detector will disable the feature.

Note: The function may need to be disabled if minimum fan speed causes thedetector to exceed smoke response time requirements set by relevantnational and international approvals bodies.

Mains check

Use the Mains check function when the detector is connected to a power supply with integral fault relay. The power supply fault relay is connected to one of the detector’s remote inputs and the relevant input number is entered into the numerical box next to the function (reading “0” in Figure 5-13).

When the Mains check box is selected, the detector will generate a fault condition when the power supply indicates a fault. The function is disabled by default.

Battery check

Use the Battery check function when the detector is connected to a power supplywith backup batteries and an integral battery fault relay. The power supply batteryfault relay is connected to one of the detector’s remote inputs and the relevant inputnumber is entered into the numerical box next to the function (reading “1” inFigure 5-13 above, indicating input “I/P 1”).

When Battery check is selected, the detector will generate a fault condition whenthe power supply indicates a battery fault. The function is enabled on “I/P 1” bydefault, as shown in Figure 5-13.

If backup batteries are not to be used, the function should be disabled to preventthe detector generating a battery fault.

Attimes specified in this function, the detector will switch between the two histograms. This willmake the detector more sensitive during inactive (Night) periods, when the ambient smokedensity is less, and less sensitive during the active periods (Day) when smoke density is higher.

Both histograms are optimized to the working environment, and they are automatically set upduring the initial 24-hour learning period.

For this function to work correctly, the detector’s internal clock must be set to local time.

The software automatically compensates for one-hour changes in local time (for example, thestart of Daylight Savings Time).

You can modify the following Day/Night Switching function settings as described inTable 5-10:

5-2.2.9 REFERENCING

The Referencing device settings only apply to detector units and not the Command Module.

Figure 5-16 shows the Referencing function settings screen for a Detector device (“Detector003”).

Figure 5-16. Referencing Function Settings Screen

There may be occasions when external pollution enters a protected area and it is undesirableto generate a fire alarm, such as smoke from an external furnace entering the open doors ofa factory. A reference detector can be used to “back-off” such a spurious external smokereading to prevent detectors inside the protected area from generating unwanted alarmsignals. Any detector in a network may be set as a reference detector.

You can modify the following Referencing function settings as described in Table 5-11:

Table 5-10. Day/Night Switching Function Settings

Setting Function

Day startMakes the detector less sensitive during active periods (Day) when smokedensity is higher.

Night startMakes the detector more sensitive during inactive periods (Night) whensmoke density is lower.

Disable day/night switching

Where there is no distinction between “active” and “inactive” periods (suchas a factory operating on a 24-hour basis or in a climate-controlledmicroelectronics clean room), select (enable) the Disable day/nightswitching box to stop the switch-over function.

Day/night switching may be carried out manually by assigning one ofthe remote terminals in the detector or on an input/relay card. (SeeSection 1-9.1 for details.)

P/N 33-308100-006 5-19 June 2009


To implement the referencing function:

1. Select the smoke detector to use as a reference detector.

2. Perform a smoke test.

3. Using the histogram screen, note the maximum output level reached by the referencedetector.

4. Select the address of the smoke detector in the histogram screen.

5. Note the time interval before the detector output level begins to rise and the maximumsmoke detector output level is reached.

6. Divide the increase in output level at the detector by the increase seen at the referencedetector.

7. Enter this fraction as a percentage into the Reference Level function

8. Enter the time delay into the Reference Back-off function.

9. Enter the address of the reference detector into the Reference Detector function andselect (enable) the Reference Enable box.

The reference system is now enabled. The unit will then begin a FastLearn, followed by a24-hour learning period in order to optimize the system.

5-2.2.10 MISCELLANEOUS

The Miscellaneous device settings only apply to detector units and not the Command Module.

Figure 5-17 shows the Miscellaneous function settings screen for a Detector device(“Detector 001”).

Table 5-11. Referencing Function Settings Screen

Setting Function

Reference detectorThis is the address (as set on the detector’s internal DIP switch) of the detector to be used as a reference.

Reference level

This is the percentage of the reference detector’s output signal to be subtracted from the detector. The default value is 0.

The Reference Level function reflects the fact that smoke seen at a referencedetector may be diluted by the time it reaches the smoke detector.

For example, smoke might be diluted by 75% by the time it reaches a smokedetector. Under these circumstances, you should subtract 25% of the referencesignal from the detector. Therefore, if the “nuisance” smoke causes an increase insignal at the reference of 10% full-scale output, setting the reference level to 25%will subtract 2.5% detector output from the smoke detector. This means that anyrise in smoke over and above this 2.5% level is probably due to a genuine firecondition in the protected area.

Reference back-off

This is the time delay in minutes before smoke seen at the reference detector isseen at the detector. The default setting is 15 minutes.

The Reference Back-off value reflects the fact that it may take time for smokeseen at the reference detector to reach the smoke detector.

Reference enable Selecting this box enables the reference detector. The box is cleared by default.

You can modify the following Miscellaneous function settings as described in Table 5-12:

Table 5-12. Miscellaneous Function Settings

Setting Function

Access code

Set by default to 0102. You can change the Access code function to any 4-digit number to prevent unauthorized modifications to detector functions.Once the code is set, the new 4-digit code is required for a user to access theSenseNET function settings page or to program the detector from a CommandModule or the detector’s front panel (if fitted appropriately).

Chart recording rate

Sets the resolution of the detector’s chart recording. The shorter the intervalselected, the greater the resolution, but the shorter the period covered by a fullchart.

The chart recording can capture 2000 samples before it begins to overwrite theolder entries.

A variety of preset recording intervals is available from the drop-down list, from10 seconds/division to 500 mins/division, recording detector level and alarmlevel. The same set of preset values is available with the suffix “air flow.” Inthese cases, the chart recording captures the flow rate instead of the alarmlevel.

Changing the chart recording period clears the current chart recording, as doespowering down and removing and replacing the memory backup link. However,normal power-downs will not clear the current chart recording.

5-3 PC COMMAND MODULE

Selecting the PC Command Module option from the Options menu opens the CommandModule settings screen (see Figure 5-18):

Figure 5-18. Command Module Settings Screen

The SenseNET system uses a Command Module to interrogate all the devices on the bus anddetermine their status. This can be either a hardware Command Module or a software modulein the PC running SenseNET.

Note: SenseNET software has the ability to be a Command Module, enabling SenseNET to runwithout a hardware Command Module, although this is not a fault tolerant configurationand is not recommended for large systems or systems where reliability is of a highimportance.

The following Command Module settings can be modified as described in Table 5-13:

Separator condition

The detector continuously monitors the condition of the dust separator (filtercartridge). You cannot edit the value displayed in this box. After a period oftime, the separator begins to fill with dust and reduces the amount of smokereaching the detector. The ClassiFire system compensates for such dustloading, reducing the figure in the Separator condition box as it does so. Anew filter will read 99 and the software will automatically generate aSeparator renew fault when the separator condition figure reaches 80.

Separator change date

On a site with many detectors, it may be more convenient to change all thedust separator filters at a planned interval (for example, during sitemaintenance). Entering a date in the Separator change date field generates aSeparator renew fault on this date, regardless of the actual condition of thedust separator. However, if the filter becomes clogged before this date, aSeparator renew fault will still be generated.

Factory defaultSelecting (enabling) the Factory default box and selecting <OK> resets allprogrammable functions to their default settings.

5-7 PAGER SETTINGS

You can configure SenseNET to automatically send a Pager message when an alarm or faultoccurs. To use this function, a modem must be connected to a second serial port or an internalmodem must be fitted to the PC.

When the Command Module is fitted with a modem connected to its internal RS232 terminals,it can send an alert to a pager or GSM-capable telephone in the case of an alarm or a fault.This is done by the modem dialing a central call center and instructing the call center to senda message to the pager using the Telecommunications Alphanumeric Protocol (TAP).

Some GSM phone service providers also provide the facility to send SMS messages using theTAP protocol.

To use paging, a Hayes compatible modem must be permanently connected to a COM port onthe PC. This COM port is additional to the one required for communication to the bus.

When an even occurs that needs signaling, the paging subsystem will try to send the messageuntil it is either sent successfully or it is canceled.

Note: Sending messages to a pager is not fully fault tolerant and must not be used as theprimary method of signaling alarms or faults.

Device Address Table

APPENDIX BDEVICE ADDRESS TABLE

B-1 DEVICE ADDRESS TABLE

In order to identify itself to the Command Module or fire panel, each detector needs to have aunique address ranging from 1 to 127. The detector address is simply set on the DIP switchSW1 at the bottom left of the opened detector on the main circuit board. The switch settingsare UP position for “1” and DOWN position for “0”. The detector address is set as a 7-bit binarycode (switch 8 equates to a value of 128 and so is outside the usable address range).

Figure B-1 shows some sample DIP switch settings.

The address equates to 01100011 in binary, or:

(1 x 1) + (1 x 2) + (0 x 4) + (0 x 8) + (0 x 16) + (1 x 32) + (1 x 64) + (0 x 128) = 99

The ClassiFire System

APPENDIX DTHE CLASSIFIRE SYSTEM

D-1 ABOUT CLASSIFIRE

ClassiFire® is the patented artificial intelligence system for the AIR-Intelligence line ofAspirating Smoke Detectors that continually monitors the environment and internalcontamination and automatically adjusts sensitivity to the optimum level.

ClassiFire automatically adjusts sensitivity to suit day/night or operational/non-operationallevels with no need for external input.

ClassiFire automatically sets up the detector to the normal working environment so thedetector sensitivity is optimized for its surroundings.

AIR-Intelligence detectors are fully automatic and do not need manual adjustment.

D-1.1 The Detector Levels

The FIRE level always appears at level 8 on the display bargraph, as shown below inFigure D-1:

Figure D-1. ClassiFire Alarm Indicator

P/N 33-308100-006 D-1 June 2009


An additional user-definable AUX level can be set to any position on the bargraph from Level1 to Level 10 as shown in Figure D-2. (See Section 5-2.2.4 for details on how to set the AUXlevel.)

Figure D-2. AUX Alarm Level

A user-defined Pre-Alarm level can also be used when early warning is required (as shown inFigure D-3). (See Section 5-2.2.4 for details on how to set the Pre-Alarm level.)

P/N 33-308100-006 D-2 June 2009


When the predetermined level of smoke is reached, the Fire Alarm is activated (as shown inFigure D-3).

Figure D-3. Fire Alarm Activation

A second Fire alarm level, Fire 2 Alarm, is provided. This level may be pre-programmed toprovide an indication when it is required for a higher smoke density. This is typically used forthe operation of automatic fire extinguishing systems.

D-1.2 Sensitivity Levels

The alarm factor allows detectors to adapt to the working environment more or less closely,depending on the degree of protection required or the type of facility you want to protect.

The following Alarm Factor settings give a starting point for the protection of a wide range ofenvironments:

• Alarm Factor 0: clean rooms (highest sensitivity)

• Alarm Factor 1: computer rooms

• Alarm Factor 2: non-smoking offices

• Alarm Factor 3: clean factory

• Alarm Factor 4: warehouses

• Alarm Factor 5: warehouses with diesel trucks (lowest sensitivity)

See Section 5-2.2.4 for details on setting Alarm Factor sensitivity levels.

D-1.3 ClassiFire Operation

ClassiFire considers the likelihood of a “nuisance” alarm being generated by normal operatingconditions. Each of the six Alarm Factors balances the degree of protection required againstthe probability of a nuisance alarm.

The calculated probability of nuisance alarm ranges from an average of one nuisance alarm peryear (for Level 0) to one per 5000 years (for Level 5).

The detector samples air once per second and passes information on the smoke density of eachsample to ClassiFire.

P/N 33-308100-006 D-3 June 2009


In a working environment, the density of smoke in the atmosphere continually varies. Thedetector needs to be able to discriminate between normal pollution caused by workingactivities and pollution caused by early signs of fire. ClassiFire sets and maintains sensitivityby continual statistical analysis of the data received.

D-1.3.1 BUILDING A DISTRIBUTION PLOT

ClassiFire builds a continually varying distribution plot of how the smoke density varies withtime. For each sample taken, ClassiFire records the particle density, assigning each densityrecorded against a sample class and logs the number of samples in each class.

Low and high values are rare. Most samples tend to cluster around the average level or themean. Graphs which group samples into pre-defined classes are called histograms.

ClassiFire divides the range of sampled smoke densities into 32 classes and counts the numberof samples which fit into each category. The most recent data is considered most significantwhile older data has proportionately less significance.

ClassiFire models the smoke densities against the normal distribution. For example, the normaldistribution can be found in all continuously variable functions, such as the heights of a largegroup of men. However, if you drew a graph showing the number of men at each height (ahistogram), after a while you would begin to see the histogram fill out until it begins toapproximate a normal distribution.

Figure D-4. A Normal Distribution of Men’s Heights

June 2009 D-4 P/N 33-308100-006


Figure D-5 shows the normal distribution curve of men’s height.

Figure D-5. A Normal Distribution Curve

D-1.3.2 BUILDING A CLASSIFIRE HISTOGRAM DISTRIBUTION CURVE OF SMOKE DENSITY

Figure D-6 demonstrates how ClassiFire builds a smoke density distribution curve by collectingdata on smoke density.

Figure D-6. Building a ClassiFire Smoke Density Distribution Curve (Histogram)

P/N 33-308100-006 D-5 June 2009


Figure D-7 below shows a distribution curve fully populated with smoke density data.

Figure D-7. Fully Populated Distribution Curve

Two basic concepts of statistical analysis of a normal distribution curve are:

• Mean of the distribution: The center of the distribution and the base around whichprobabilities are determined.

• Variance or spread of the distribution: Indicates the amount of spread in thedistribution.

If the mean changes but the variance remains constant, the shape of the plot remains the same(as shown in Figure D-8).

Figure D-8. Mean Changes/Variance Remains Constant

June 2009 D-6 P/N 33-308100-006


But the distribution curve moves along the axis as the level of smoke increases (as shown inFigure D-9).

Figure D-9. Distribution Curve Moving Along Its Axis as Smoke Level Increases

If the variance changes, but the mean remains constant, the center of the curve stays in thesame position but the width of the plot changes (as shown in Figure D-10).

Figure D-10. Low Variance/Mean Constant

P/N 33-308100-006 D-7 June 2009


Figure D-11 shows a moderate variance.

Figure D-11. Moderate Variance

Figure D-12 shows a high variance.

Figure D-12. High Variance

The plot can be broken down into blocks (classes) of equal width on either side of the mean.These blocks are called Standard Deviations (SD). The probability of a random event fallingoutside this area of the graph is the same for all normal distributions.

The actual width of one SD depends on the variance, but one SD has the same statisticalsignificance for any normal distribution.

Most of the events within a normal distribution are within 3 SDs either side of the mean (+ 3SD). Readings outside this range are likely to be non-random factors, such as the start of a fire.

June 2009 D-8 P/N 33-308100-006


Figure D-13 shows one SD.

Figure D-13. One Standard Deviation

Figure D-14 shows two SDs.

Figure D-14. Two Standard Deviations

P/N 33-308100-006 D-9 June 2009


Figure D-15 shows two SDs.

Figure D-15. Three Standard Deviations

The probability of nuisance alarms caused by random events outside the zone of distributionshown in Figure D-15 is very small (since low readings can be ignored). Thus, ClassiFire canstatistically base the sensitivity of the detector on the actual working environment.

ClassiFire maintains the alarm levels at the appropriate number of SDs above the mean smokelevel to provide the optimum level of protection required while maintaining nuisance alarms ata low and defined level.

If the environment changes (such as day to night, air filtration or use of area varies),distribution, mean, and variance also change. ClassiFire continually updates the alarm levelsto maintain the same position from the mean. This provides an unchanging level of protectionby continuously varying the alarm parameters.

D-1.3.3 FASTLEARN

When a detector is first powered up, it automatically enters FastLearnTM mode for 15 minutes.This permits rapid approximation of normal smoke density.

During the FastLearn period, there is insufficient data to set an accurately defined alarm level.After the 15-minute period, the detector has collected an approximation of the smokedistribution. This data is placed into a “slow” histogram to set up the initial alarm settings.

ClassiFire initially places the alarm level several SDs from the mean reading to take intoaccount the fact that the histogram is still being sparsely populated and narrow.

D-1.3.4 INTERMEDIATE LEARN

Over the next 24 hours, ClassiFire develops a histogram to represent the standard range ofsmoke pollutants in the normal operating environment. As more data is collected to cover non-working periods, ClassiFire incorporates two types of histograms:

• Fast: Monitors short-term variation in smoke density

• Slow: Builds up over 24 hours to for a complete picture of the smoke density distributionfor day and night (or active and inactive) periods.

June 2009 D-10 P/N 33-308100-006


The Alarm level position is initially set well away from the mean to take into account thesparseness of the data (as shown in Figure D-16).

Figure D-16. Initial Alarm Level Position

When FastLearn has finished, the data on the smoke density becomes the basis for a long-termhistogram. The slowly updating histogram now takes over to form the basis for future settings.As the histogram only has 15 minutes of data, ClassiFire begins to perform a more refined anddetailed analysis.

After 24 hours, the detector has enough data about the working environment and sets thealarm flag based on the level of protection required based on the distribution of data (as shownin Figure D-17).

Figure D-17. The Alarm Flag After 24 Hours

P/N 33-308100-006 D-11 June 2009


D-1.3.5 SENSITIVITY LEVELS

Smoke levels will usually increase during the day. When the protected area is unoccupied,there may be lower levels than in working periods. If the detector sensitivity were set to a fixedfigure, there may be unwanted alarms or delayed alarms at night.

• High sensitivity: Means maximum protection but a higher risk of nuisance alarms duringworking hours.

• Lower sensitivity: Protects against unwanted alarms during the day, but is not as effectiveat detecting the earliest signs of a fire.

An ideal detector needs to be able to be pre-set to at least two different sensitivity levels toprovide the optimum coverage. The ClassiFire Artificial Intelligence process does thisautomatically.

ClassiFire uses two sets of histograms:

• Day: Reduces sensitivity for normal working practices and minimizes the risk of nuisancealarms.

• Night: Increases sensitivity of lower smoke density during night or holiday shutdownperiods, maximizing protection when the protected area is unoccupied.

These two types of histograms are dynamically and continuously updated to ensure that alarmlevels are optimally set.

During the day, ClassiFire keeps the fire alarm flag out of the nuisance zone, a set number ofstandard deviations from the active histogram mean, based on the alarm factor chosen (asshown in Figure D-18).

The fast histogram updates continually in the background and is shown dotted in blue forreference. The previous “inactive” histogram is maintained in the background and is shown inFigure D-18 dotted in yellow.

Figure D-18. The Fast Histogram

June 2009 D-12 P/N 33-308100-006


When work stops in the protected area and people leave, the smoke level starts to drop (asshown in Figure D-19). The fast histogram mean tracks the smoke level and begins to divergefrom the active histogram mean, taking on new data at a sampling rate of once per second.The alarm setting remains based on the active histogram mean.

Figure D-19. Dropping Smoke Level After Work Stops in the Protected Area

As the active histogram reduces, it approaches the previous night’s histogram mean. When thehistogram mean has reached 2/3 of the distance towards the previous night’s mean, ClassiFirechecks to see if the time is within +70 minutes of the programmed switch-over time (as shownin Figure D-20).

Figure D-20. Histogram Reaches 2/3 of the Distance from the Previous Night’s Mean

P/N 33-308100-006 D-13 June 2009


If so, the inactive histogram immediately takes over and the alarm flag is repositioned basedon this latest data. The previous active histogram is saved in the background to await the nextchangeover time, when the “search” process is repeated (as shown in Figure D-21).

Figure D-21. Inactive Histogram Takes Over and Alarm Flag Repositioned

If there is no smoke reduction measured within +70 minutes of the programmed time,ClassiFire stays with the currently selected slow histogram. That means that during weekendsor holiday periods, the inactive histogram remains in force.

The currently selected slow histogram is updated over the remainder of its active period so thatthe mean is always based on the most recent environment.

In addition to detecting the change from active to inactive periods, ClassiFire also takes intoaccount the time in which the change occurred.

For example, if there is a change in working hours so that people leave at 6PM instead of 5PM,ClassiFire adjusts the changeover time by an amount proportional to the difference from thepreset time. After a few days, the system switches over according to the new working times.

Note: The larger the time difference, the larger the change.

D-1.3.6 SETTING THE DETECTOR

To set detector operating values, select Device settings from the SenseNET Options drop-down menu.

Figure D-22. Selecting Device Settings from the Option Menu

The following detector values relate to ClassiFire operation:

1. Detector’s clock and calendar. (See Section 5-2.2.3 for details.)

2. Pre-Alarm and AUX alert levels (if required).

a. Pre-alarm defaults to 6 on the bargraph (adjustable from 3 to 8)

b. AUX defaults to 10 (adjustable from 2 to 10)

(See Section 5-2.2.4 for details.)

3. Day and night changeover times (if required). The preset times when day and nighthistograms activate can be set the nearest hour on a 24-hour clock.

a. Day defaults to 08 (8AM)

b. Night defaults to 19 (7PM)

c. If no changeover is required (for example, a 24-hour working day), you can set theDay and Night times to “00”.


4. ClassiFire alarm function. The alarm delays prevent the detector from reacting to alarmconditions caused by a one-off peak waiting to see if the condition persists. The alarm delaycan be set between 0 and 60 seconds. The default setting is 5 seconds.


Classifire automatically (see Section D-1):

• Adjusts sensitivity to suit day/night or operational/non-operational levels with no need forexternal input

• Sets up the detector to the normal working environment so the detector sensitivity isoptimized for its surroundings

P/N 33-308100-006 D-15 June 2009


D-1.3.7 AUTO FASTLEARN ENABLE

From time to time the detector needs to be powered down for routine maintenance. Settingthe Auto FastLearn function to “n” prevents the detector from going into FastLearn mode whenpowered up, reducing down time.

The default setting is “y”.

D-1.3.8 REMOTE DAY/NIGHT

Where a remote switch is fitted, enabling the Remote Day/Night by setting it to “y” preventsthe changeover between night and day setting to occur (except manually via the remoteswitch).

The default setting is “n”.

D-1.4 Real Time ClassiFire Viewer

Nuisance alarms, alarms being signaled because the detector is over-sensitive for itsenvironment, can often occur with high sensitivity aspirating detectors that have fixed,absolutely scaled alarm thresholds. ClassiFire is a patented feature, unique to AIR-Intelligencedetectors, that enables the detector to continually learn and adjust to its environment, settingits alarm levels appropriately to get the optimum level of protection without nuisance alarms.

SenseNET has a real-time ClassiFire Viewer screen (shown in Figure D-23) that demonstrateshow the detector is continuously setting its alarm levels and scaling its smoke densitybargraph.

Figure D-23. Real-time ClassiFire Viewer Screen

The histogram (shown in Figure D-23) shows a detector working in a stable environment,resulting in a narrow distribution of histogram classes. The numerals on the bargraph are not
