The Single IR Rear Viewing specialist flame detector is designed for machine applications to protect enclosed, dark areas where visible light is not present. This detector has high sensitivity to flame and sparks and has a very fast response time. The detector has one infra-red (IR) sensor, which is selective to low frequenct modulated infra-red (IR) radiation such as that emitted from flames and sparks. 

The detector rejects static radiation from sunlight and artificial lighting.
