Fig. 14.6. Channel housing smoke detector
Diagnosing the function states of the smoke detector:
Normal operation: Detector light under the removable cover at the rear lights up green
Smoke alarm:
Detector LED lights up red
Service alert:
When the detector detects smoke or is dirty, the green LED lights up first
before going into the red alarm state.
If the detector is dirty, it will show a green light. This is an optical indication
(prealarm or service alarm), which means that the sensor is dirty and if it is
not cleaned, it will later give a false alarm.
Fault:
The alarm relay will switch the contacts:
a)
in case the sensor module is removed
b) in the event that the supply voltage is interrupted
NOTE!
In the event of a smoke detector malfunction, the "Collective fault" light on the TSS or TS panel
and the MAC-FC controller issues a fault signal to the CSP. First of all, the smoke detector must
be cleaned according to the instructions below. If cleaning does not eliminate the failure, inform
the SMAY service immediately. Do not repair or replace the smoke detector yourself. This can
only be done by SMAY service or an authorised SMAY service.
