NOTE
Pressing the sensor replacement switch prevents
the communication module from generating a fault
signal when the input drops to zero. In addition,
the calibration will not be aborted if the calibration
procedure is not completed within 12 minutes.
2.
Apply zero gas.
3.
The calibrate LED on the communication module
blinks at a 1 Hz rate, indicating that it is ready for
the zero input.
4.
Continue from step 4 of the PointWatch routine
calibration procedure described above.
UV DETECTOR TEST
CAUTION
To prevent unwanted actuation, alarm and
extinguishing devices must be disconnected prior
to performing detection system tests.
FIRE ALARM TEST
1.
Disable any extinguishing equipment that is
connected to the system.
2.
Apply input power to the system. Allow a one
second power-up delay.
3.
Hold a UV source (W8066) within the cone of vision
of the detector at a distance relative to the selected
detection range. Verify that an alarm condition is
indicated at the LCU. Reset the alarm indication
using the key switch on the LCU.
Lack of response may indicate reduced sensitivity
due to contamination on the viewing window, a
damaged sensor, or electronic circuitry or wiring
problems. Refer to “Troubleshooting” for additional
information.
4.
Repeat this test for each fire detector in the system.
5.
Verify that all detectors are properly aimed at the
area to be protected.
6.
Enable extinguishing equipment when the test is
complete.
FALSE ALARM TEST
1.
Disable all alarm response equipment.
2.
Allow the system to monitor the protected area for a
period of time with all the normal operations in the
area taking place. If the detector responds
(indicating a fire when no fire has occurred), check
the area to see if UV sources are present. If
possible, remove the sources, or reposition the
detectors so that the sources fall outside of the
detector’s cone of vision. If problems still occur,
adjust the time delay, sensitivity or arc rejection
settings.
The model U7656 Hand-Held UV Monitor is
available from Detector Electronics for conveniently
scanning the protected area and pin-pointing the
exact source of UV radiation.
3.
Recycle power and test again as described above.
4.
Once the correct settings are obtained, turn on all
alarm and extinguishing equipment that is
connected to the system. Record all switch settings
for future reference.
UV/IR DETECTOR TEST
IMPORTANT
Disable any extinguishing equipment that is
connected to the system to prevent unwanted
actuation.
The detector can be tested by shining a UV/IR test lamp
(W867 or W8067) into the detector viewing windows or
by a live fire. (Refer to the test lamp manual for specific
instructions regarding proper use of the device.) This
will cause the detector to go into an alarm condition —
the LEDs on the UV sensor will be on steady and the
LCU will indicate an alarm condition. If latching
operation is selected, the detector will remain in this
condition until it is reset at the OIS. If non-latching
operation is selected, the detector will return to normal
operation as soon as the test is terminated (the test
lamp or fire source is removed).
If a fire signal was not generated and the LEDs indicate
response by
only one
sensor, the other sensor has
failed to respond.
— Check the cleanliness of the viewing window and
repeat the test.
— If the sensor fails to respond again, replace the
sensor module.
— If the sensor still does not respond, replace the
detector.
