product description

The OT-H-IR4 infrared flame detector contains four infrared sensors and optical filters. The main sensor has the highest sensitivity to the CO2 emission spectrum (4.4 μm) generated by the combustion of hydrocarbons, and the other three infrared sensors are sensitive to ambient light 3. The background light source interference of hot body radiation is used for detection. The detector has multiple signal processing algorithms, combined with the logical comprehensive judgment of the flame flicker frequency, to maximize the suppression of false alarms and the best fire detection performance.

The special fire signal processing method and multi-sensor detection technology greatly improve the sensitivity and response time of the detector.

The detector is suitable for liquid and gas fires, open flames accompanied by smoke and places where deflagration occurs.
