AUTOMATIC AIR VENTS-In addition to the manual air vents described above, automatic air vents of size 25 mm shall b placed at the top of the chilled water riser piping in the building. Operation of



Automatic air vent: The float of the air vent keeps the venting valve closed.

The process is a continuous one as long as air is collected in the vent valve. The air cushion in the upper part of each vent valve protects the venting valve against corrosion. When the pressure inside the system decreases below the ambient pressure, for instance during draining of the system, the air vent acts as a vacuum breaker, and lets air into the system.

Access control devices and systems comprise an important part of every security system. Even the simplest single-door access control system includes at least an electric strike to automatically unlock the door, a timer to make sure that the door does not stay open all day, and a bell or light to indicate when the door is opened or that it has not reclosed properly. In a large-scale security system there may be intrusion alarms, exit alarms, closed-circuit surveillance, guards and patrols, physical barriers and turnstiles, and a variety of other devices and systems. The combined advantages of these elements constitute an effective physical security system. In TICEL Phase -III Project, A door Access Controller has been proposed to control access to IBMS centre. Boom Barriers are proposed to manage the entry and exit to premises. For ensuring security, security personnel are provided with a rechargeable hand held metal detector.

2.6 Data Networks

2.6.1 Description

The IBMS and TICEL Office network is connected with high speed 1000Mbps data networks making use of CAT6 cables and optical networks wherever necessary. Due to inherent limitation of 100 meter length for Cat5 or Cat6 networks, design should take care of this limitation. This can be achieved by providing network switches within the vicinity of end devices such that they won’t exceed the length of 100m. To achieve this, it is suggested that a network switch may be introduced at 5th or 6th floor. Wherever necessary, single mode fiber optics cable can be used to achieve full 1000Mbps bandwidth. Since the distance between IBMS and utility building are more than 100m, fibre optic connectivity has been proposed to link them together with single mode 6 core OFC cable. It is proposed that CCTV, Data network share the same resources like racks, switches wherever possible.

2.6.2 Active Components The main active components of data network are Switches. Switches shall be of 24 ports, PoE. Switches shall be smart/web managed with features like VLAN, QoS. Additionally it shall have 2xSFP ports for connecting fibre links. The switch shall provide a minimum of 15.4 watts and have 802.3af compliant ports at the minimum.

2.6.3 Passive Components All the copper based passive components like patch panels, patch cords, keystones, jacks, data outlet faceplates etc shall be of CAT6 standard. All the cores of OFC cable shall be properly terminated in a rack mounted or rack mounted LIU as per site conditions. All the fibre optic passive components like LIU, pig tails, patch cords are SC compatible to keep it economical. The SFP modules shall be supplied as recommended by the switch manufacturer and shall be compatible with switch supplied.
