Description
The product is a conventional optical sensor which incorporates a chamber housing, an Infra-Red (IR) LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber, the light bounces off the smoke particles and strikes the photodiode, causing it to generate an alarm condition when a set threshold value is met. The product uses the optical radiation (visible in this instance) for the purposes of physical analysis. The product does not contain an integral sounder or recording device.
