activation, notification devices will activate in this building. The remaining smoke detectors
throughout the residence will sound a local alarm and will not generate a signal at the FACP.
The residential area only is equipped with a new fire sprinkler system. When a fire starts, the
fusible links at the sprinkler heads are melted, allowing water to flow from
the system. A flow or pressure switch triggers an alarm within the building. The fire alarm panel
will notify the central monitoring station.
An alarm condition will notify the central monitoring station via the DACT connection.
A tamper(supervisory) and trouble condition will notify the central monitoring station via the
DACT connection.
Le. Testing Criteria
Section 1 —Testingi Criteria
Personnel:
a) The General Contractor in association with the Electrical and Fire Protection Contractor will
coordinate the actual test dates. This date will be based upon completion of installation of all
components.
b) Upon completion of a successful pre-test, the Contractor shall notify the Professional in
Charge that all systems are ready for a final test. The Contractor will provide the professional
with documentation that all equipment was 100%tested and that the system is ready for a

General trouble signals (open short or ground on SLC and NAC circuits, open short or
ground on an IDC circuit, low battery, AC power fail, loss of smoke detector power, etc.)
will generate a signal to the FACP &ANN. The central monitoring station will be notified by
direct dial from the FACP primary and back-up telephone lines.
c) Notification Devices and Functions:
Horns/strobes to be distributed throughout to meet the visual and audibility requirements of
NFPA 72.
Exterior weatherproof strobe with red lens to be installed outside the store front, above the
fire key knox box. The strobe shall activate upon all fire alarm activation.
Audio/visual devices will sound upon any alarm signal. When alarms are silenced by the fire
department, strobes shall continue to flash until the fire alarm panel is reset.
Trouble signals will not activate the interior/exterior horn/strobes but will be reported to the
central monitoring station via direct connect dial as noted elsewhere.
Remote test stations shall be labeled with "red text" for the devices they serve.
d) Fire Alarm System Auxiliary Functions:
Upon a general fire alarm condition, all HVAC units will be shut down.
e) Fire Extinguishers:
Fire extinguishers are provided throughout the facility in accordance with NFPA 10.
