Overview:
Spot-type infrared flame detector consists of two infrared sensor and optical filter, with high sensitivity to CO2 emission spectrum (4.4µm), and another
infrared sensor detects the interference of environment light and thermal radiation, with multiple signal processing method on measured result,
combining logic comprehensive judgement from the flame flicker frequency in the fire so as to restrain false alarm to the greatest extent, and to get
optimal fire detection performance. Flame detector possesses early alarming for the fire arising from hydrocarbon or other organic material.
Flame detector is able to work under industrial environment of high temperature, high humidity, vibration, etc.
Flame detector is capable of remote detection, completing the setting, with help of the remote, for analog test, alarm reset, alarm delay of the fire
alarm function of detectors, and setting for relay output mode contact locking & non-locking work mode.
Flamer detector is capable of field setting for the sensitivity via internal jumper.
Flame detector has gained CCCF certificate and National Anti-explosion certificate, satisfying the requirement of GB15631-2008, GB3836.1-2010 and GB3836.2-2010.
