S600-ExIR2 point infrared flame detector (dual wavelength, flameproof type)

The S600Ex-IR2 point-type infrared flame detector contains sensors with two infrared detection wavelengths and an optical filter. The detector has high sensitivity to the CO2 emission spectrum (4.4μm) produced by the combustion of hydrocarbons. The other infrared sensor performs spectral detection to detect interference from ambient light and thermal radiation. The detector performs complex logical calculations on the dual-parameter detection results and combines this with a comprehensive judgment of the flame flicker frequency during a fire, enabling the product to suppress false alarms caused by various ambient light interferences to the greatest extent possible. The detector is suitable for liquid and gas fires, open flames that produce smoke, and locations where deflagration may occur.
