Why does the gas alarm sound randomly? How to prevent false

Users who have gas alarms installed at home may encounter such problems by chance. While cooking, the gas alarm installed in the kitchen suddenly sounds, but no signs of gas leakage are found in the kitchen. Why is this? Let's take a look together.
What factors can cause gas alarms to alarm incorrectly?
The false alarm of the gas alarm is generally affected by five major factors: cooking, steam and moisture, high flame of the stove, the gas alarm being too close to the stove, and the gas alarm having exceeded its service life.
01. Cooking
In situations where traditional Chinese medicine, heated beer and other alcoholic beverages, eggs and other food ingredients become moldy and odorous, there is a large amount of smoke indoors, and the gas alarm itself is covered with a certain amount of dust and oil smoke, the gas alarm may also misreport.
02. Steam and Moisture
In northern winter, it is not uncommon for water vapor in kitchens to be in a supersaturated state, and condensed water will condense onto sensors, triggering false alarms.
03. The flame of the stove is too high
The flame of the stove is too high, and a small amount of unburned gas floats up around the alarm, which is prone to false alarms.
04. The gas alarm is too close to the stove
The home alarm is too close to the stove, and the internal semiconductor sensor is susceptible to interference from high temperature and humidity, and there is also a risk of false alarms.
05. The gas alarm has exceeded its service life
The service life of household gas alarms is generally around 5 years. However, due to the large amount of cooking fumes in Chinese kitchens and the harsh environment, the service life of household gas alarms with the same performance is relatively shorter, and work environment pollution is also an important reason for false alarms.
How to determine if the alarm is misreporting?
After the alarm emits an audible and visual alarm signal, the user should turn off the gas and brush soap water on the gas hose, various connections, etc. for leakage. If bubbles are found, it is considered a gas leak. If no leaks are found and seasonings such as cooking wine or vinegar are not used, but the alarm continues to sound, or if there is a problem with the alarm itself, the gas company should be contacted immediately for handling.
If none of the above situations occur, it is determined that the alarm was caused by the use of seasoning, etc. The user can handle it on their own and continue using gas; If the alarm is triggered again, the gas company or manufacturer should be contacted for professional personnel to investigate the leakage.
If you want to avoid false alarms from the gas alarm during cooking, you should maintain ventilation and use a range hood while cooking.
How to prevent the occurrence of false alarms?
1. Location selection
Installed on indoor walls within 4 meters and 2 meters away from the gas appliance or gas source horizontally. If testing natural gas and artificial gas, it should be installed around 0.3 meters from the ceiling; If liquefied petroleum gas is detected, it should be installed approximately 0.3 meters above the ground.
It should be avoided to install in the following positions: passages and other places with high airflow velocity; A place with mist or dripping water; Places or high-temperature environments near the stove that are easily contaminated by oil fumes, steam, etc. (such as directly above the stove); Places obstructed by other objects (such as in cabinets); Near vibrating objects such as refrigerators and air conditioners.
2. Instrument maintenance
Under normal circumstances, the service life of the detector is more than 5 years. Please replace it promptly after the service life expires. During normal use, to prevent oil or dust from blocking the air intake, please clean it regularly with a dry towel or soft brush, and do not use cleaning agents, laundry detergent, etc.
Correct installation and use of gas alarms can reduce the occurrence of false alarms and effectively play the role of gas alarms, safeguarding family safety!
