Description
An optical smoke detector which utilises the light scatter sensing principle by using a light emitting diode (LED) & a photo diode within its sensing chamber. When smoke particles enter its sensing chamber, the photo diode senses increased levels of infra-red light scattered by smoke particles and the detector then goes into alarm mode. Therefore, the product uses optical radiation (visible in this instance) for the purposes of physical analysis. The detector is optimised for increased sensitivity to black smoke. There is no integral audio-visual warning equipment fitted but a small LED intended only to show whether the detector is in alarm condition. The detector is designed for use with a base.
