PW-507 Stand-alone UL smoke detector is 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).
9V Power Supply smoke detector, Meets CE, RoHS and EN14604
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
