PW-507 Stand-alone photoelectric smoke alarm is under BSI approval, and can be calibrated into either UL, VDS, NF Standards. It 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).



9V Power Supply, Meets CE, RoHS and EN14604



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
