3. Press the SELECT button until the desired zone is
displayed on the ZONE indicator on the controller
front panel.
4. Press and hold the TEST button. The DETECTOR/
ZONE display indicates the counts per second
(cps) received from the detector. If the counts per
second exceeds 99, the FIRE LOGIC LEDs are
illuminated to indicate that the number shown on
the display must be multiplied by 10. The normal
reading for an
oi test is 80 to 110 cps. For a live
fire test, 270 - 330 cps will be generated.
A zero reading may indicate a dirty window, oi problem,
faulty detector or defective wiring.
Release the Test button, the ZONE and DETECTOR
display should drop to a reading of 0 to 1 counts per
second.
FIRE aLaRM TEST (pulse Output to Fire alarm panel)
1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
3. Initiate a live fire test or a Mag 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. (Det-Tronics’
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 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. Check system and detector logs.
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 IR radiation by covering
the detector with the factory supplied cover or
aluminum foil. If the fault condition clears, extreme
background IR radiation 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, 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.
