Smoke alarm specifications/Special Features:

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