Model F120 UV/IR Flame Detector
Failed or Incomplete Test
When testing the ame detector, make sure to account for the time delay settings of the
detector. The ame detector has a factory default time delay setting of 3 seconds and a user
selectable setting of 6 seconds. During this time, the ame detector conrms the presence
of radiation emitted by the re before reporting an alarm condition.
The response time of the detector will depend on the distance between the detector and the
test lamp.
Causes of Failed or Incomplete Tests
If the ame detector does not respond to the test lamp, check the following:
1. Conrm the ame detector has power.
A green LED indicator is illuminated on the viewing window of the detector to indicate it
is powered and operating.
2. Verify the test lamp is working.
While the unit if off, check that there are no dust, debris, nger marks, or any type of
oily residue on the lens. Clean the lens using a clean, soft, lint-free, tissue (lotion-
free), or cotton swab with water or alcohol. DO NOT use Windex or any commercial
glass cleaners.
3. Conrm the test lamp has power.
Point the test lamp on the oor or a wall while pressing and HOLDING the power
switch. DO NOT look directly on the lens of the test lamp while it is on. The test lamp
should light up and “icker.” Reduced intensity may indicate the batteries are low.
Recharge the batteries or replace them if using a disposable type.
4. Make sure the test lamp is within 5 feet (1.5 meters) from the ame detector and
pointed directly at the viewing window of the detector.
The test lamp must be within the detector’s eld of view. Move closer to the ame
detector and repeat the test.
5. Make sure you press and HOLD the power switch while pointing the test lamp directly
into the viewing window of the detector for at least 10 seconds or until the red LED
comes on.
6. SEE “Troubleshooting” section of this manual if the ame detector doesn’t respond to
the test lamp.
