Optical Detector Orbis OP-12001

The optical smoke detector contains a pulsating LED and a photodiode.
Under normal conditions, the light generated by the LED is not registered by the photodiode.
When smoke particles enter the chamber, the light is scattered and detected by the photodiode, resulting in a signal that is evaluated. The colorless LED indicator lights up red in case of an alarm.
