What to do if the audible and visual alarm device of a gas detector fails?
Step 1: Verify the alarm parameters
Confirm whether the alarm threshold and alarm mode (such as instant alarm or delayed alarm for concentration exceeding the standard) set by the gas detector meet the actual usage requirements
Check if the mute mode has been accidentally triggered or if the alarm sensitivity has been adjusted
Step 2: Check the hardware connection
Observe the indicator light of the gas detector equipment to confirm if the power supply is normal, plug and unplug the power cord to test the contact condition
Gently shake the connection cable between the alarm device and the host. If it is loose, unplug or replace the spare cable
Step 3: System restart
After turning off the detector host, wait for 30 seconds, then turn on the alarm device and start the detector again. Observe whether the alarm light flashes during the system self-test
Step 4: Component replacement
If it is confirmed that the gas detector alarm module is damaged, it is necessary to purchase components that match the prototype number (pay attention to parameters such as explosion-proof level)
During installation, strictly follow the instructions and pay attention to the corresponding relationship between the wiring terminals
Step 5: Professional Support
If there is still no improvement after completing the first four steps, please contact the gas detector manufacturer or certified maintenance personnel in a timely manner to avoid disassembling the core components on your own. If you have purchased our Yiyuntian products, please feel free to contact us at any time. We are fully online and aim to provide high-quality after-sales service for everyone.
Daily maintenance suggestions:
Quarterly testing of alarm function with standard gas, in conjunction with cleaning of sensors
After using the gas detector in a dusty environment, clean the heat dissipation holes of the alarm device with a soft bristled brush
