General information

The optical detector provides early warning for incipient fires 
with smoke, in particular smoldering fires. The sensor cavity 
houses a light source and receiver. Normally, the pulsating 
light ray from the transmitter does not reach the receiver. If 
smoke particles enter the sensor cavity, a portion of the light is 
reflected to the receiver resulting in an alarm trigger. A red LED 
indicates the alarm. The alarm remains active until it is manually 
reset at the control unit. In normal mode, the light transmitter 
pulses every 8s to ensure a low monitoring current. The 
detector design ensures enhanced resistance to interference 
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 to avoid false 
alarms. 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.
