What should I do if the gas alarm calls the police?

1. Let's look at the main structure of the alarm. When the power cord is plugged in, it is connected with the air cut-off valve. Under normal circumstances, the alarm indicator is green. When giving an alarm, the indicator light is red and gives an alarm sound. It will actively block the gas supply after ringing for a period of time.

First, don't be nervous after hearing the alarm. First, close the valves of pipelines and gas stoves, and open the doors and windows for ventilation. At this time, it is forbidden to fire, find out the cause and location of the alarm, and take measures to eliminate the danger.

3. The danger is swept away, and the gas supply will be actively blocked after a period of alarm. We also need to manually recover and find the valve connected to the alarm. Usually we will see a prominent part, and sometimes there will be calcium.

Take off the cover, and you will see the switch inside, which is usually red. Note that the correct way is not to twist the switch, but to pinch the switch and pull it up. When you feel hitched, it means that the valve is open, and the gas supply will be resumed at this time.

5. If the alarm continues to sound soon after ventilation, please check whether there is air leakage in some areas again. If there is no air leakage, there may be something wrong with the alarm. You can test and replace the alarm.

The working principle of natural gas alarm is as follows

1. power light: green light, which will light up after power on, and will subside when giving an alarm; Alarm light: red light, which lights up when the alarm stops and goes out when the alarm stops.

2. Turn on the power. After the green light is on or on for 3 minutes, the alarm starts to work normally.

3. When the detected gas reaches the alarm point, the alarm starts to alarm, the green light turns off, the alarm light turns on, and the buzzer sounds "B, B, B…". When the concentration of the detected gas drops below the alarm point, the alarm stops (the carbon monoxide alarm has a delay function).

4. If the manual detection function is added, when the key is pressed, the green light turns off, the alarm light turns on, and the buzzer sounds "B, B, B…".

5. If the function of combined exhaust fan is added, when the alarm sounds, the connected exhaust fan will start and the toxic gas will be swept away.

6. If the function of joint manipulator or solenoid valve is added, when an alarm is given, the connected manipulator or solenoid valve will actively close the gas valve, thus blocking the harmful gas source.

7. If networking function is added, when natural gas has alarm signal, the management center or control center receives normally open and normally closed (NO, NC) signals at the same time (if wireless function is added, alarm host receives wireless signal for 2-3 seconds).
