General information
The optical detector provides early warning for incipient fires
with smoke, in particular smoldering fires.
The sensor cavity houses a light sensor and receiver.
Normally, the pulsing light ray from the transmitter does not
reach the receiver.
If smoke particles enter the sensor cavity or if the sensor cavity
is heavily contaminated, a portion of the light is reflected to the
receiver resulting in an alarm trigger.
A red LED indicates the smoke alarm. The alarm remains active
until it is manually reset at the control unit (voltage reset).
The detector design ensures enhanced resistance to interfe-
rence from air speeds, contamination, and EMC interference.
The detector module is mounted to the socket with a bayonet
lock and facilitates straightforward operation of the detector.
Fasten the smoke detector to the socket after removing the
plastic tab from the socket base.
As contamination builds up, the detector progressively
approaches the alarm threshold. The sensor is equipped with
a contamination indicator. When the contamination limit has
been reached the red LED starts flashing at 3-s intervals. Then
the detector must be cleaned by manufacturer or replaced.
If this is not done, the detector will indicate an alarm (red LED)
after additional contamination builds up.
