Smoke Detector for AOV Smoke Vent

Photo-electric detection of light scattered by smoke particles over a wide range of angles. The optical arrangement comprises an infra-red emitter with a prism and a photo-diode at 90° to the light beam with a wide field of view.

The integral LED flashes when the detector is in a quiescent state.
