The IR2LF2 sensor is designed to provide early warning of flaming fires emitting IR radiation. Infrared radiation is routed through a fibre optic cable. The IR2LF2 sensor must be connected to a LF amplifier.
The IR2LF2 sensor is equipped with an integrated, automatic monitoring facility for vision sensitivity and discontinuity of the fibre circuit.
