The Discovery Optical Smoke Detector (58000-600) uses an IR LED which pulses light across a smoke chamber with a photo-diode set at an obtuse angle. In clear air it receives no light, but when smoke enters the chamber, light from the LED is scattered onto the photo-diode. Then the signal is processed to provide an analogue value for transmission when the detector is polled.
