This product is suitable for places where natural gas exists. It can be used for safety detection and alarm for accidents such as combustion, explosion, poisoning caused by gas leakage. The product has the characteristics of high sensitivity, high stability, full detection gas type, small size, and optional use of backup batteries.
When the concentration of flammable gas in the environment around the alarm reaches the set value of response concentration, it can send out sound and light and network alarm signals.
2. In the alarm state, when the concentration of flammable gas in the surrounding environment drops below the response concentration set value, it can automatically return to the normal monitoring state. The alarm is red, yellow and green.
A status indicator and a built-in buzzer indicate the following three states: the green indicator is always on, the alarm power supply is working normally, and it is in the monitoring state; the yellow indicator is on and
Accompanied by a buzzer, the alarm is faulty (mainly sensor failure); red indicator light
Blinking, accompanied by buzzer and network output, indicating that the product is in an alarm state. The green light is off, the yellow light flashes once every 30 seconds, and the product is disconnected from the 220V power supply.
9V battery power supply (low voltage when the battery voltage is lower than 8.2v, the phenomenon is a buzzer sound when the yellow light flashes)
