4. Place a momentary ground fault on the SLC circuit to verify
operation of the ground fault detection circuitry.
5. Run a system detector sensitivity report on all detectors and verify
that readings fall within acceptable limits.
6. Perform a sensor function test, as described below.
To perform sensor function tests:
1. If desired, use the fire alarm control panel to put the detector or
zone into a service group for testing. (Refer to the panel technical
reference manual for instructions.)
2. Activate the smoke sensor using No Climb Products model Smoke
Centurion/M8, FireTech Smoke or Smoke Sabre smoke aerosol
spray, a smoke generator, or the Testifire detector tester per the
manufacturer’s instructions.
3. Activate the heat sensor using a hair dryer (maintaining a distance
of three inches) or using a Testifire detector tester per the
manufacturer’s instructions.
Maintenance
To ensure proper operation, plan maintenance (regular or selected) of
the detector in accordance with the AHJ and all applicable governing
laws, codes, or standards. Refer to CAN/ULC-S536
Standard for the
Inspection and Testing of Fire Alarm Systems
and NFPA
72 National
Fire Alarm and Signaling Code.
Refer to Technical Bulletin P/N 3102625-EN for additional information
and cleaning instructions.
