b) Smoke test
Taking a smoldering cotton rope close to the
detector, blow the smoke into the detector until the
detector generates alarm.
c) Temperature test
Approach a heater (such as a hair drier) to the
thermistor of the detector until it alarms.
3) After testing, disconnect the power to the detector for
over 5 seconds to reset it. Notify the proper authorities
that the system is back to normal operation.
If a detector fails in testing, clean it by the steps in
Maintenance, and retest it. If it still fails, return it for
repair.
Maintenance
The detector should be installed just before
commissioning and kept well before installation,
taken corresponding measures for dust-proof,
damp-proof and corrosion-proof.
The dust-proof cover should not be removed until
the project is plunged into usage. Otherwise it may
not report alarm properly.
Clean the detectors regularly, at least once a year
to ensure normal operation of the system.
If unwanted alarms are often found of the detector
on site, the sensing chamber should be cleaned.
Power must be removed from the detector before
cleaning.
Steps for chamber cleaning:
a) Open the top cover of detector, and draw out
the sensing chamber by slightly lifting its two
sides using a straight screwdriver, as shown in
Fig. 5.
Fig. 5
b) Clean the internal of the chamber by alcohol
cotton swab with tweezers or using clean water
and brush. Make sure not to leave any fiber in
the chamber.
c) Put back the chamber and the top cover.
Before cleaning, notify the proper authorities that
the system is under maintenance and will
temporarily be out of service. Disable the automatic
controls relating to the zone or system under
maintenance to avoid unwanted actions.
The detector should be tested after re-installed to
ensure normal operation.
Fire simulation test should be done to the detector
at least every 6 months.
