STaRTuP PROCEDuRE
When installation of the equipment is complete, perform
the “Fire Alarm Test” below.
FIRE ALARM TEsT
1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
3. Initiate an
oi test. (See “Magnetic oi / Manual oi ”
under Optical Integrity in the Description section of
this manual.
4. Repeat this test for all detectors in the system. If
a unit fails the test, refer to the “Troubleshooting”
section.
5. Verify that all detectors in the system are properly
aimed at the area to be protected. (The Q1201C
Laser Aimer is recommended for this purpose.)
6. Enable extinguishing equipment when the test is
complete.

WarnIng
The sensor module (“front” half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the field.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Inspect the viewing windows for contamination and
clean as necessary. (Refer to the “Maintenance”
section for complete information regarding cleaning
of the detector viewing windows.)
3. Check input power to the unit.
4. If the fire system has a logging function, check the
fire panel log for output status information. See Table
4 for information regarding 0 to 20 mA output.
5. Turn off the input power to the detector and check all
wiring for continuity. Important: Disconnect wiring
at the detector before checking system wiring for
continuity.
6. If all wiring checks out and cleaning of the oi plate/
window did not correct the fault condition, check
for high levels of background UV or IR radiation by
covering the detector with the factory supplied cover
or aluminum foil. If the fault condition clears, extreme
background UV or IR radiation is present. Re-adjust
the view of the detector away from the UV or IR
source or relocate the detector.
If none of these actions corrects the problem, return the
detector to the factory for repair.
NOTE
It is highly recommended that a complete spare
be kept on hand for field replacement to ensure
continuous protection.
