Reasons and solutions for false alarms and disorderly alarms of combustible gas detectors
Combustible gas detector is a type of detector that can be widely used in places where combustible gases, vapors, and other substances are emitted. When the concentration of combustible gases in the detected area reaches the alarm set value, the detector immediately sends out sound and light alarm signals to remind the early adoption of safety measures, prevent explosions, fire accidents, and ensure fire safety. However, during the use of combustible gas detectors, there may be issues with false alarms and disorderly alarms. What are the reasons for this?
1. Installed in areas with high airflow;
2. Installed next to vibrating objects such as air conditioners;
3. Spray paint around the combustible gas detector and spray a large amount of irritating gas;
4. When the green light flashes (flashing indicates preheating status, and constantly on indicates entering working status), perform a jet check;
5. During installation, vibration, drop, and impact combustible gas detectors;
6. The combustible gas detector is too close to the stove;
7. There is a large amount of thick smoke indoors, and the gas alarm itself is covered with a certain amount of dust and oil smoke;
8. The combustible gas detector has exceeded its service life, etc.
When the combustible gas detector experiences false alarms or disorderly alarms, it is necessary to first confirm whether the machine is a false alarm.
The solution to false alarms and disorderly alarms of combustible gas detectors is as follows:
1. Determine if the gas concentration is seriously exceeding the standard, and if so, take immediate measures;
2. Check if the sensor is damaged. If so, it is recommended to return it to the manufacturer;
3. Check if there are any issues with the circuit;
4. Check if the combustible gas detector is set correctly.
