Det-Tronics X3300EXE Protect-IR Multispectrum IR Flame Detector - Manual (Page 11)

FIRE ALARM TEST
1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
3. Connect the oi test line to dc minus for 5 to 10
seconds or perform a pan fire test. The alarm relay
will change states and the red alarm LED will
illuminate when the device goes into an alarm
condition.
4. Disengage the oi test line or extinguish the test fire.
If the Alarm relay is configured for the standard
non-latching operation, it will change states and the
red LED will turn off. If the unit has latching relays,
they can be reset by removing input power (0.1
second minimum).
5. Repeat this test for all detectors in the system. If a
unit fails the test, refer to the “Troubleshooting”
section.
6. Verify that all detectors in the system are properly
aimed at the area to be protected.
7. Enable extinguishing equipment when the test is
complete.
TROUBLESHOOTING
WARNING
The detector contains no user serviceable
components and should never be opened.
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 for complete
information regarding cleaning of the detector
viewing window.)
3. Check input power to the unit.
4 If the fire system has a logging function, check the
fire panel log for relay status and/or 4 to 20 mA
output information. See Table 4.
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.
