This section covers all Fire Alarm System Installation work. It includes furnishing all labor, equipment, materials and performing all operations related to the entire Fire Alarm System. This section covers the installation of Fire Alarm System equipment.

 

The entire installation must conform to NFPA 72 [A][B][C] [D][E] [F], Local Code requirements, and National Electrical Code, with special attention to Article 760. This section of specifications covers work that must be coordinated with related work, as described elsewhere in the project specifications.

 

General requirements for a fire alarm system

Install a fire alarm system according to the specifications and plans. It must be wired and connected and maintained in a first-class operating condition. The system will use closed loop initiating devices circuits with individual zone supervision and individual indicating device circuit supervision. It also includes incoming power supervision. A control panel, manual pull stations and automatic fire detectors are included.

The fire alarm control panel will allow editing or loading of special instructions and operating sequences by using a program mode dip button. The system can be programmed using standard tools and models or an off-board programmer. This will allow for expansion, building parameter changes, or other changes required by local codes. All instructions must be stored in the fire alarm control panel’s non volatile, programmable memory. Instructions stored in memory will not be erased if there is a loss of primary or secondary power.

All panels and peripheral devices must be the standard product from a single manufacturer. Each component shall bear the manufacturer’s name. This section’s catalogue numbers are those of Simplex Time Recorder Co. They indicate the type, product quality and material as well as desired operating features.

Equipment submission must contain at least the following:

Complete description data indicating UL listing of all system components
The complete sequence of operations for the system.
Diagrams of the entire system, including wiring diagrams and interfaces to other equipment.
If required by the local jurisdiction, a copy of any equipment approvals for state or Local Fire Alarm System (if applicable).

 

Supervision of the Fire Alarm System

1 The system must contain [8-32] [class B (style ‘B)] independently monitored initiation circuits, so that any fault in one zone does not affect the other. Alarm activation of any initiation system shall not stop the operation of any subsequent alarm circuit.

2 There shall be two (2) independent supervised fused indicating circuits for alarm [horns] alarm bells [chimes] [and flashing lamp alarms] that are [2, two] [4, four][6, six]. The operation of other circuits will not be affected by any disarrayment.

3. All auxiliary manual controls must be monitored so that all switches can be reset to their normal position in order to resolve system problems.

4 Each circuit independently supervised shall have a separate amber “trouble LED” to indicate circuit disarrayment.

5 All incoming power must be monitored so that any power outage at the control panel (and remote annunciator) is audibly and visually reported. While incoming power is available, a green “power on” LED must be visible continuously.

6 System batteries must be monitored so that low battery conditions or the disconnection of the battery are audibly and visually indicated at both the control panel [and remote annunciator].

7. System expansion modules connected via ribbon cables must be monitored for module placement. If a module is disconnected from the CPU, the system trouble indicator should illuminate and an audible signal must sound.

8 The supervision of open and ground conditions must be given when wiring to a non-serial remote annunciator (hardwired) An annunciator trouble indicator should be installed. It must be lit and an audible warning signal should sound at the control panel if there is ground or open condition.
