5.0 FIRE DETECTION
5.1 INTRODUCTION
All fire systems require regular testing and maintenance. Common dust buildup in
smoke detectors can cause them to false alarm or fail in a time of need. Consult
your Security Company Representative for a scheduled maintenance program.
All devices in a Fire Alarm system should be tested monthly except as described in
NFPA 72.
5.2 WHEN AN ALARM OCCURS
When a fire alarm occurs, the bell sounds, the keypad(s) produces the fire alarm
tone and displays the message “FIRE ALARM” and the fire alarm system zone that
initiated the alarm.
DO NOT IMMEDIATELY ASSUME IT IS A “FALSE ALARM”!
The occupants should respond according to the fire escape plan that has been
developed for the building. Only if the person responsible for the building and the
safety of its occupants is certain that the alarm has occurred as a result of some
other cause, should an occupant silence a fire alarm signal. To silence an alarm
signal, the operator presses the ALARM SILENCE key (button) and then enters the
passcode.
5.3 RESETTING THE FIRE ALARM SYSTEM
After the site has been secured, the source of a fire alarm initiation has been
identified and corrected, and the building is deemed safe for occupancy it is
necessary to “reset” the fire alarm system. This is necessary because smoke
detectors and fire alarm control panels “latch” in the ALARM state until they are
intentionally “reset” by an individual with access to the fire alarm system controls.
To reset the system depress the SYSTEM RESET key (button) and enter the
passcode. The trouble condition should disappear on the zone in a couple of
seconds. If the trouble condition does not clear after resetting the smoke detector,
contact your Fire Protection Representative for service.
