Status Indications and Troubleshooting
During normal operation the Detector Status
indicator LED will flash green every 10
seconds, and both Fire and Fault relays will be
in their normal position.
If the detector is in Fault state, its LED will flash
amber every 10 seconds to indicate Signal
High/Low Fault, every 5 seconds to indicate
AGC/Compensation Fault, and every 3 sec-
onds to indicate Internal Fault. The Fault relay
will change state.
If the detector is in Fire state, its LED will flash
red every 5 seconds and the Fire relay will
change state.
The Detector will automatically compensate
for dust build up by changing its AGC level.
Once the AGC limit has been reached, the
Detector will indicate a Fault and cleaning must
be performed.
It is therefore recommended that the Detector
lens windows and the Reflector are
periodically cleaned with a soft lint-free cloth to
prevent AGC limit faults occurring.
After cleaning, if the Detector is in Fault state,
the signal strength may have increased above
the Signal Too High threshold. If this is the
case, re-align the Detector.
After installation or cleaning it is recommended
that a Fire test is performed.
Fire Test: Cover the reflector slowly so that
it takes longer than 5 seconds to cover. The
Detector will indicate Fire after 10 seconds.
Alternatively, use the Alarm Filter from the
Fireray Commissioning Kit which will test 25%
35% and 55% alarm thresholds.
