Description

IFD20-IR2 dual infrared flame detector is a kind of new-type intelligent fire detection equipment. This detector adopts the high-performance dual infrared sensing technology, and is provided with three infrared sensors with different wavelengths and narrow-band filtering. One sensor is used to reflect the central wavelength of the flame information, and the other is used to monitor other infrared radiation in the environment. Combined with the flicker characteristics of the flame, the radiation spectrum with flame characteristics can be identified as a fire alarm by means of the operational analysis with the high-speed microprocessor and technical algorithm. This detector is able to suppress the interferences such as sunlight, lightning, electric welding, thermal radiation, electromagnetic interference, mechanical vibration, etc., is provided with strong anti-interference capacity, and can quickly respond to and accurately identify the flame signal.
