Wireless Smoke Alarm is kind of photoelectric smoke detector, is the use of smoke particles in infrared light refraction fire detection principle, the circuit consists of infrared-emitting portion and receiving parts, the launch tube and receiving tube placed in the optical maze, optical maze maskable external stray light interference, but does not affect the smoke into the detectors.
Under smoking status, receiving tube receives only a very weak infrared light, when smoke enters Wireless Smoke Alarm, due to scattering, the received optical signal enhancement, when the smoke reaches a certain density, the Wireless Smoke Alarm Detector output alarm signal.
Features of Wireless smoke detector alarm :1. Adopted MCU auto-processing technology, stability improved;
2. Wireless network function;
3. Hush function;
4. Fault auto checking function;
5. Auto reset;
6. Infrared photoelectric sensor;
7. Sound &flash alarm/LED indicator;
8. SMT manufacture technology adopted, high stability;
9. Dustproof, mothproof, anti light interference design;
