When the gas detector detects, the gas will also alarm when the gas does not reach the alarm value
1. Check whether the various alarm parameters of the gas detector have been modified;
2. Check whether the alarm mode and alarm mode of the gas detector have been modified;
3. Check whether the alarm state of the gas detector is a concentration alarm or other fault alarm. The concentration alarm appears A1 or A2, and the red light flashes;
4. If the gas detector alarm is caused by manual modification, it can be solved by restoring the factory installation. The fault alarm needs to be further checked for short circuit, open circuit, poor contact, sensor failure, etc., or return to the factory for inspection.
