Thanks to the use of the principle of spectral selection has high speed and no false alarms from incandescent lamps, fluorescent lamps, solar radiation.
It is connected to a two-wire fire alarm loop and is designed to work in conjunction with fire alarm control panels (FCP) and signal-launching devices (SLD), providing a constant supply voltage in the fire alarm loop with permissible periodic interruptions or polarity reversal with a duration of no more than 100 ms and a repetition rate of no more than 1.5 Hz. The output signal is formed by increasing the detector current consumption.
Due to the use of the principle of spectral selection has high speed and no false alarms from incandescent lamps, fluorescent lamps, solar radiation.
Designed for indoor installation.
