Optical smoke detector ,under BSI approval, and can be calibrated into either UL, VDS, NF Standards. This smoke detector features UL-approved Photoelectric sensing components with precise smoke detection. and long life (18 months) 9V battery operation (9V UltralifeLithium battery model for 10-year life is available too).
Optical smoke detector features and sepcifications:
• Features:
o Works on principle that infrared scatters on smoke surface
o Probes smoke which is generated by incomplete combustion at initial stage of fire
o Smoke detector consists of photoelectric system, signal processing identification and alarm circuit
o Infrared scatters on surface of smoke when smoke enters darkroom of detector
o Photoelectric diode receives scattered light and generates photoelectric signal current
o Photoelectric signal generates alarm signal after being processed by identification circuit, accordingly purpose of alarming is achieved
