The Fyreye optical smoke detector incorporates a pulsing infra red LED Located in an optical chamber inside the detector. The chamber is designed to eliminate the effect of any external light source.
A Photodiode is located inside the optical chamber at an angle to the IR LED. Under normal conditions no IR reaches the photodiode. But when smoke enters the chamber it causes the IR to scatter, and this will then be picked up by the photodiode. If the photodiode “sees” smoke on the 2 following pulses, the detector enters the alarm state, and lights its LED.
