Smoke detector 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 detector 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
