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
o
i
test (see “Magnetic
o
i
/
Manual
o
i
” 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 of this manual.
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.
TROUBlESHOOTING
WARNING
The sensor module (“front” half of the
detector) contains no user serviceable
components and should never be tampered
with.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Inspect the viewing windows for
contamination and clean as necessary. The
detector is relatively insensitive to airborne
contaminants, however, thick deposits of
ice, dirt, or oil will reduce sensitivity. (Refer
to the “Maintenance” section of this manual
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 3 for information
regarding 0–20 mA output.
5. The use of the Enhanced Flame Inspector
cable and software from Det-Tronics can be
considered to determine the nature of the
fault condition. Refer to instruction manual
95-8751 for more information.
6. 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.
7. If all wiring checks out and cleaning of
the
o
i
plate/window did not correct the
fault condition, check for high levels of
background IR radiation by covering the
detector with the factory supplied cover
or aluminum foil. If the fault condition
clears within six minutes or less, extreme
background IR is present. Re-adjust the
view of the detector away from the IR source
or relocate the detector.
If none of these actions corrects the problem,
please contact your local Det-Tronics
Representative or alternatively you may contact
Det-Tronics Technical Support by calling 1-800-
765-3473 ext 2 (M-F, 8am to 5pm CST) to obtain
assistance.
NOTE
It is highly recommended that a complete
spare be kept on hand for eld replacement
to ensure continuous protection.
