Committee Statement

CommitteeStatement:

While the term "de-rating" refers to de-rating the manufacturer's specified capacity and thereforerequires that the battery installed has more capacity than the system load would otherwise require,the Technical Committee agrees that eliminating the term "de-rating" would make it clearer thatcreating a battery capacity safety margin is the intent. Both the battery capacity and the safetymargin are required to be documented so the Technical Committee has included the word "and" inthe requirement.

10.6.5.1 Branch Circuit.

10.6.5.1.1

The branch circuit supplying the fire alarm equipment (s) or emergency communication system(s) shall besupplied by one of the following:

(1) Electric utility

(2) An engine-driven generator or equivalent in accordance with 10.6.11.2, where a person trained in itsoperation is on duty at all times

(3) An engine-driven generator or equivalent arranged for cogeneration with an electric utility inaccordance with 10.6.11.2, where a person trained in its operation is on duty at all times

10.6.5.1.2 *

The branch circuit supplying the fire alarm system component(s), carbon monoxide system component(s),or emergency communication system component(s) equipment shall supply no other loads.

A.10.6.5.1.2

Multiple pieces of system equipment can be connected to a branch circuit, subject to the current capacityof the circuit. It is not intended that a branch circuit be limited to a single piece of equipment. It is notintended that the circuit supply power to other than system equipment. For example, a branch circuit couldpower both a fire alarm control unit and a NAC power supply, but it could not power both a fire alarmcontrol unit and a sprinkler system air compressor.

A.10.6.7.2.3

Committee Statement

CommitteeStatement:

The Technical Committee revises the text to limit the required 12 hours of notification applianceoperation to those notification appliances used for carbon monoxide notification, which is consistentwith the requirements of NFPA 720-2015. There is no substantiation to support limiting the requiredhours of operation for those devices in the spaces protected by the CO detection, as it is equallyimportant to warn against entering a hazardous area with notification appliances placed outside thespace protected by the CO detection devices.

10.12.2*

When an occupant notification alarm signal deactivation means is actuated, both audible and visible visualnotification appliances shall be simultaneously deactivated.

A.10.12.2

Where it is desired to deactivate the notification appliances for fire service operations inside the building andsignal evacuated occupants that an alarm is still present, it is recommended that a separate non-silenceablenotification zone be provided on the exterior of the building. The audible and visible visual notificationappliances located at the building entrances could serve as a warning to prevent occupant re-entry.

Committee Statement

CommitteeStatement:

In response to PC 523:

Proposal: Change Audible Alarm Notification Appliance to Audible Notification Appliance to maintainconsistency.

Response: The sections of Chapter 10 have been changed. These lines (10.10.2 and 10.10.3)specifically refer to alarm notification and one may have trouble or supervisory audible notifications. Thisis specifically intended to discern it as an alarm notification.

Proposal: Change Visible to Visual.

Response: Sections 10.11.2, and 10.11.3 are under the purview of SIG-ECS, so a recommendation willbe sent to that Technical Committee to review these sections. Per the Chapter 18 Task Group tostandardize terminology, the Technical Committee has revised 10.12.2 accordingly. However theTechnical Committee affirms that 10.6.7.2.1.5, 10.11.8.1, 10.11.8.2, 10.13.1, 10.13.2.1, 10.13.6.1,10.13.6.2, 10.14.7, 10.14.9.1, 10.14.9.2, 10.15.1, 10.17.1.1, 10.17.1.1.1, 10.17.1.1.2, 10.17.2.1,10.17.2.1.1, 10.17.2.1.2, 10.17.4, meet the exception criteria in substantiation #2 of PC 523.

Proposal: Change Audible Fire Alarm Signals to Audible Notification Signals to maintain consistency.

Response: Section 10.18.1 is specific for a fire alarm system in this instance, and does not apply to anyother systems.

Proposal: Change Audible Indicators to Audible Notification Appliance to maintain consistency.

Response: Section A.10.10.4 is annex material referring to older systems.

Such correspondence should be authorized and recognized by the sender as an official representation oftheir organization and clearly identifiable from the recipient's perspective as having been authorized by thesender. Examples of correspondence made "in writing" could include, but not be limited to, hard copy ordigital notification that includes company letterhead or other type of company designation, authorizedsignatory or signatories either in digital form or on hard copy, or in an email signature block, etc., or anycombination thereof. Examples where such correspondence would be required could include, but not belimited to, test plans, inspection and testing reports, notification of deficiencies/corrections, change ofsupervising/central station providers, notification of recalled equipment or suspected low audibility levelsfor alarm signaling.

The definition of "in writing" should not be applied to text messages, voice mails, notations on scratchpaper, or any similar means of notification that fail to reflect the verifiable and authenticated nature ofcorrespondence that is submitted "in writing", as that term is defined by this Code .

Second Revision No. 1018-NFPA 72-2017 [ Section No. A.10.6.6 ]

A.10.6.6

Where a computer system of any kind is used to receive and process alarm or supervisory signals, anuninterruptible power supply (UPS Energy Storage System (ESS ) with sufficient capacity to operate thesystem until the secondary supply is capable of operating the fire alarm system might be required in orderto prevent signal loss or a greater than 10-second signal delay.

UPS ESS equipment often contains an internal bypass arrangement to supply the load directly from theline. These internal bypass arrangements are a potential source of failure. UPS ESS equipment alsorequires periodic maintenance. It is, therefore, necessary to provide a means of promptly and safelybypassing and isolating the UPS ESS equipment from all power sources while maintaining continuity ofpower supply to the equipment normally supplied by the UPS ESS .

A.10.6.7.2.1.1

The 20-percent safety margin is intended to address normal aging effects ona on battery'scapacity capacity . As a battery ages, rated capacity will decrease to 80 percent, which is considered theend of service life. As a minimum, a 20-percent correction factor should be applied for aging to ensure thebattery can meet its current demand at the end of service life. At initial installation battery capacity can beas low as 90 percent and should gradually increase when subjected to several deep discharge/chargingcycles or remains on float-charge for several weeks. For additional information on battery sizingconsiderations refer to IEEE 485, Recommended Practice for Sizing Lead-Acid Batteries for StationaryApplications.
