1.Introduction
FD10-IR2 double IR flame detector is a new type of intelligent fire
detection equipment. The detectors uses 2 infrared sensors with
different wavelengths with narrow-band filtering. One sensor is
used to reflect the center wavelength of the flame information. The
other sensor 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.
