Fire infrared detector

Fire infrared detector

A sensitive element in a fire detector that can convert the infrared radiation of a flame into an alarm signal output by an infrared detector. When a target in the detector's field of view generates a flame, an alarm signal can be immediately issued. Commonly used fire infrared detectors are lead sulfide, and indium antimonide, germanium-doped mercury, and mercury cadmium telluride are also used.
