Description
Point-type Infrared and Ultraviolet Flame Detector – Overview
The point type IR/UV flame detector uses two low-noise infrared pyroelectric sensors, an UV sensor and a high-speed microprocessor. Through the FFT processing algorithm and optical path self-check algorithm, only radiation that meets the flame characteristics will be identified as a fire alarm. The UV sensor is particularly sensitive to metal combustion and hydrogen combustion, and has good anti-interference ability and a longer flame detection distance. Once a flame is detected, it will immediately alarm and report to the IoT platform through the fire alarm control panel, and at the same time link the relay to output a control signal.
