Include battery-operated emergency power supply with capacity for operating system in standby mode for 24 hours followed by alarm mode for 5 minutes.

C. System Supervision: Component, wiring or power supply failure places system in trouble mode.

D. Initiating Device Circuits: Supervised zone module with alarm and trouble indication; occurrence of single ground or open condition places circuit in trouble mode but does not disable that circuit from initiating an alarm.

E. Indicating Appliance Circuits: Supervised signal module, sufficient for signal devices connected to system;

occurrence of single ground or open condition places circuit in trouble mode but does not disable that circuit from signaling an alarm.

F. Remote Station Signal Transmitter: Electrically supervised digital alarm communicator transmitter, capable of transmitting alarm and trouble signals over telephone lines to central station receiver.

G. Auxiliary Relays: Provide sufficient SPDT auxiliary relay contacts for each detection zone to provide accessory functions specified.

H. Provide TROUBLE ACKNOWLEDGE, DRILL, and ALARM SILENCE switch.

I. Trouble Sequence of Operation: System or circuit trouble places system in trouble mode, which causes the following system operations:

1. Visual and audible trouble alarm indicated by zone at fire alarm control panel.

2. Visual and audible trouble alarm indicated at remote annunciator panel.

3. Trouble signal transmitted to central station.

4. Manual acknowledge function at fire alarm control panel silences audible trouble alarm; visual alarm is displayed until initiating failure or circuit trouble is cleared.

J. Alarm Sequence of Operation: Actuation of initiating device places circuit in alarm mode, which causes the following system operations:

1. Sound and display local fire alarm signaling devices.

2. Transmit non-coded signal to central station.

3. Indicate location of alarm zone on fire alarm control panel and on remote annunciator panel.

4. Transmit signals to building elevator control panels to initiate return to main or alternate floor.

5. Transmit signal to building mechanical systems to initiate shutdown of fans and damper operation.

6. Transmit signal to release door hold-open devices by zone.

K. Alarm Reset: System remains in alarm mode until manually reset with key-accessible reset function; system resets only if initiating circuits are out of alarm mode.

L. Lamp Test: Manual lamp test function causes alarm indication at each zone at fire alarm control panel and at annunciator panel, but does not cause alarm or trouble signals to be sounded or transmitted off site.

M. Drill Sequence of Operation: Manual drill function causes alarm mode operation as described above.

N. Zoning: As indicated.

2.2 INITIATING DEVICES: Installed devices may be reutilized if compatible with new system. (Provide

Explosion Proof devices where noted as “EP”) A. Manual Pull Station: Semi-Flush mounted, non-coded type, single action manual station.

B. Spot Heat Detector: Fixed temperature, Combination rate-of-rise and fixed temperature, rated 57 degrees C except as shown on drawings.

C. Ceiling Mounted Smoke Detector: NFPA 72, photoelectric type with adjustable sensitivity, plug-in base, auxiliary relay contact, integral thermal element rated 57 degrees C, and visual indication of detector actuation, suitable for mounting on 102 mm outlet box. Provide two-wire detector with common power supply and signal circuits unless coordinated otherwise.

D. Duct Mounted Smoke Detector: NFPA 72, photoelectric type with auxiliary SPDT relay contact, key-operated NORMAL-RESET-TEST switch, duct sampling tubes extending width of duct, and visual indication of detector actuation, in duct-mounted housing. Provide two-wire detector with common power supply and signal circuits unless coordinated otherwise.
