Specifications/Special
Features:
Features:
1.Works on principle that
infrared scatters on smoke surface
2.Probes smoke which is
generated by incomplete combustion at initial stage of
fire
3.Smoke detector consists of
photoelectric system, signal processing identification and alarm
circuit
4.Infrared scatters on surface
of smoke when smoke enters darkroom of detector
5.Photoelectric diode receives
scattered light and generates photoelectric signal
current
6.Photoelectric signal
generates alarm signal after being processed by identification
circuit, accordingly purpose of alarming is achieved
