Wireless Smoke Alarm - China manufacturer of Security & Protection Products

 
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;

Fire Alarm System Conventional photoelectric smoke detector - China manufacturer of Smoke Alarm

Photoelectric Smoke Detector also known as an Optical Smoke Detector that detect the smoke by a couple of infrared diodes. Photoelectric Smoke Detector contains a light source (typically an incandescent light bulb or light-emitting diode), a lens, and a photoelectric receiver.

Photoelectric Smoke Detector infrared diodes are placed in the special chamber. The chamber can shield external light, but don't affect the smoke into it. While have no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.

the Photoelectric Smoke Detector product uses a unique structural design, and the use of intelligent MCU photoelectric signal processing, with dust, pest control, anti-light interference and other functions, to ensure the stability of the product from the design. Suitable for various installation environments, improve the user's perception of the alarm signal.
