VESDA air
detector
network
Check the connection of
air detectors.
The air detectors
are securely
connected.
Connect the air detectors
securely.
Smoke
detectors
Use a dedicated test
instrument or a smoke
generator to blow
smoke to a smoke
detector and check the
indicator status on the
smoke detector.
If the smoke
density is
below the
alarm
threshold, the
alarm
indicator
blinks once
every six
seconds.
If the smoke
density
exceeds the
alarm
threshold, the
alarm
indicator is
steady on.
If the smoke density is
below the alarm threshold
but the alarm indicator
blinks twice every six
seconds, the smoke
detector is faulty. Replace
the smoke detector.
If the smoke density
exceeds the alarm
threshold but the alarm
indicator is not steady on,
replace the smoke
detector.
For details about how to
replace a smoke detector, see
7.1 Replacing a Smoke
Detector
NOTE
You are advised to clean smoke
detectors every two years.
Heat
detectors
Use a dedicated test
instrument or a blow
drier to check the heat
detectors. Observe the
alarm indicator.
NOTICE
To prevent damage to the
heat detector probe, keep
a proper distance between
the sensor probe and the
blower drier.
If the
temperature
is below the
alarm
threshold, the
alarm
indicator is
blinking.
If the
temperature
exceeds the
alarm
threshold, the
alarm
indicator is
steady on.
If the temperature is
below the alarm threshold
but the alarm indicator is
steady on, replace the
heat detector.
If the temperature
exceeds the alarm
threshold but the alarm
indicator is not steady on
(that is, no alarm is
generated), replace the
heat detector.

replace a heat detector, see
