5. TESTING
1.
All the alarm signal devices, releasing devices and
extinguisher systems should be disabled during the
test period and must be re-enabled immediately at the
conclusion of testing.
2.
After energising the detector head for approximately
one minute, check to see the indicator green LED
flashing once every 3~5 seconds (this may be difficult
in strong light as the flash is only dim). If green LED
fails to flash, it indicates the non-functioning of the
detector or faulty wiring. Re-check the wiring or replace
the detector if necessary.
SMOKE SENSOR TESTING
Allow smoke from a test smoke aerosol to enter the
detector-sensing chamber for at least 2-3 seconds.
When sufficient smoke has entered the chamber, the
detector will signal an alarm, this being visible by the
continuous illumination of the LED. Reset each detector
and/or control unit before attempting to test any
additional detectors on the same zone. If the alarm fails
in during this step, it indicates a defective unit, which
requires service/replacement.
HEAT SENSOR TESTING
The detector to be tested should be subject to a flow of
warm air at a temperature of between 65
°
C and 80
°
C or
by using a dedicated heat detector tester.
Proceed as follows:
a.
Switch on the warm airflow and check that
temperature is correct and stable.
b.
From a distance of several inches, direct the
airflow at the guard protecting the thermistor.
The detector should alarm within 30 seconds
c.
Upon alarm immediately remove the heat
source and check that the red LED of the
detector is illuminated. Reset the detector from
the control panel.
d.
If detector fails to go into alarm mode within 30
seconds it is too insensitive and needs to be
returned to the distributor for servicing.
3. If using a dedicated heat detector tester following the
manufacturer
’
s instructions.
4. After testing, check that the system is set for normal
operation and notify the appropriate authorities that the
testing operation is complete and the system is active
again.
NOT SUITABLE FOR INSTALLATION IN AREAS
WHERE AIR VELOCITIES EXCEED 300 ft/min
6. MAINTENANCE
The recommended minimum requirement for detector
maintenance consists of an annual cleaning of dust from
the detector head by using a vacuum cleaner.
