55000-390APO AlarmSense Optical Smoke Detector
The AlarmSense Optical Smoke Detector works using the light scatter principle. The detector changes to alarm state at a pre-set threshold of smoke penetration into the sensing chamber.
- EN54-7 Optical Smoke Detector
- BS 5839 Compliant
- Easy to Install and Extend
The optical smoke detector uses an internal pulsing LED and a photo-diode at an obtuse angle.
In the event of smoke entering the chamber, the light pulse from the LED will be scattered
and registered by the photo-diode. The detector will then enter the alarm state and the indicator LED lights up.
AlarmSense sensors must be mounted on AlarmSense bases (45681-244)
Dimensions: 100mm x 42mm
