The gas detector is normal. What light is on?

There are usually three colors of indicator lights on the gas alarm, and the types of indicator lights will be marked below, namely green power light, yellow fault light and red alarm light. When gas leakage is detected, the red alarm light will light up, and when there is a problem with the gas alarm, the yellow fault light will light up. Common faults can be roughly divided into sensor faults and communication faults, which can be repaired after investigation. Let's look at the details. 1. How many lights are there in the gas alarm?

Household gas alarms usually have indicator lights, which are used to display the status of gas alarms. There are usually three indicator lights, namely:

1, power light, usually green.

2. Fault light, usually yellow.

3. Alarm light, usually red.

Second, the gas detector is normal. What light is on?

Under normal circumstances, if the gas detector is used normally, only one of the three lights will light up. Under normal circumstances, the alarm will detect itself after being electrified. If no gas leakage is found, the green power light will light up. When it is detected that the gas concentration exceeds the set threshold, the red warning light will light up.

Generally speaking, the yellow fault will not always be on. If it is on, it means that the gas alarm is out of order and needs to be checked and repaired in time. What should I do if the gas alarm fault light is on?

Third, how to solve the problem that the gas alarm is on?

As an electronic product, gas alarm will gradually age with the extension of use time, and various failures may occur. When the gas alarm fails, it will be accompanied by a warning that the fault light is on to inform the user that there is a problem with the equipment. The following are some common fault causes and solutions:

1. The display board and the output board do not communicate: check whether the cable connecting the display board and the output board is loose and plugged tightly.

2. Sensor failure of gas detector: Reconnect the sensor or replace it with a new one.

3. Communication failure of gas detector: Check whether the connecting wire of gas detector falls off or is loose.

4. Chip failure of gas detector: Common chip failures mainly include memory chip failure and clock chip failure, which cannot be solved by themselves, so it is necessary to return to the factory for maintenance and replace the main board of gas alarm.

5. The circuit connected to the gas detector is short-circuited: check the bus circuit and adjust the circuit with short circuit.

Generally speaking, the fault types of gas alarm system are mainly divided into two types: sensor fault and communication fault, which can be maintained after troubleshooting. If you don't know much about maintenance, it is recommended to find a professional maintenance person or contact the property and gas company and ask them to send someone to repair it.
