            FD10-IR3 Triple IR Flame Detector

            Response spectrum range: 3.8μm, 4.3μm, 5.0μm

            Response time: <30s

            Ingress protection: IP66

            Supply voltage: DC24V±6V

            The longest detection distance can reach 50 meters



            FD10-IR3 triple IR flame detector is a new type of intelligent fire detection equipment. The detectors uses 3 infrared sensors with different wavelengths with narrow-band filtering. One sensor is used to reflect the center wavelength of the flame information. The other two sensors is used to monitor other infrared radiation in the environment. Combining with the flicker characteristics of the flame, analyzing through high-speed microprocessors and calculating by mathematical algorithms, the radiation spectrum with flame characteristics is confirmed as a fire alarm.

            The detector suppress the interference of sunlight, lightning, electric welding, thermal radiation, electromagnetic interference, mechanical vibration and other interference, thus achieving the rapid response and accurate identification of the flame signal.


            Using high-speed, low-consumption and high-performance 32-bit data processing chip

            Excellent resistance to radio frequency and electromagnetic interference

            Perfect patent algorithm, fast response, high stability, strong anti-false alarm ability

            The longest detection distance can reach 50 meters
