The gas alarm is a gas leak detection alarm. 本产品适用于天然气存在的场所，对由于气体泄漏发生的燃烧、爆炸、中毒等事故可以进行安全检测及报警。 When the gas leaks in the environment and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poison alarm, the gas alarm will send out an alarm signal. This product is suitable for places where natural gas exists. Fire, explosion, poisoning and other accidents can be detected and alarmed. The product has the characteristics of high sensitivity, high stability, all kinds of detection gas, and small size.
When the concentration of flammable gas in the surrounding environment of the alarm reaches the set value of response concentration, it can send out sound, light and network alarm signals. In the alarm state, when the flammable gas concentration in the surrounding environment drops below the response concentration set value, it can automatically return to the normal monitoring state. The alarm has red, yellow, and green status indicators and a built-in buzzer, which indicate the following three states: the green indicator is always on, the power supply of the alarm is working normally, and it is in the monitoring state; Accompanied by buzzer sound and network output, the alarm is faulty (mainly sensor failure); red indicator light Flashing with buzzer sound And network output, indicating that the product is in an alarm state.
