Man Hours 1
Special Instructions:
The work required by this procedure may cause the activation of an alarm and/or a
supervisory signal. The office manager and the control center or fire
department that will receive the alarm and/or signal must be notified prior to
start of work. When it is both feasible and safe, the environmental conditions
being monitored should be altered to actuate the device.
Items to Check & Initial Completion:
1.___ Inspect conduit for loose hangers or clamps.
2.___ Ion chamber detectors (including duct type) - activate alarm with aerosol
spray or by blowing smoke near detector. Test for proper signals. Check
air sampling tubes for duct type. Clean according to manufacturer's
instructions.
Note: It is specifically prohibited to use aerosol sprays which contain
chlorofluorocarbons or halogens. Aerosol sprays with zero ozone
depletion potential are available on the open market.
3.___ Self-restoring temperature detectors - increase temperature or mechanically
complete circuit and test for proper signals. Make adjustments if
necessary (snap action or bi-metallic strips).
4.___ Non-restorable temperature detectors - check tension on thermostatic cable.
Check continuity of circuits by use of test buttons or by mechanically
completing circuit. Test for proper signals.
5.___ Pneumatic tube detectors - in locations susceptible to damage, check tubing
for crimps or damage. Heat tubing by means of resistance heater, hot
water, etc., and test for proper signals. Adjust release device and
replace diaphragm if necessary.
6.___ Photoelectric detectors (including duct type) - inspect for proper
alignment. Diffuse or obstruct the light rays and test for proper signals.
Check air sampling tubes for duct type. Clean according to manufacturer's
instructions.
7.___ Water flow alarms (zoned) - open valve to test pipe or drain pipe (usually
located at sprinkler risers) or open inspector's test valve (located at end
of most remote branch line) and check for proper transmission signals from
water flow paddle alarms or pressure switches. This should be done in
conjunction with alarm check valve maintenance. (See Inspection
FPACHKVV-A).
8.___ General - check other features for activation by the devices through the
fire alarm control panel. These features include alarm bells, elevator
capture, releasing of fire doors held open, notification of fire
department, smoke control, etc.
