With the improvement of people's living standards and the enhancement of environmental protection awareness, convenient and clean gas has entered thousands of households and become an important part of people's life. At the same time, the flammable and explosive properties of gas also make the gas alarm become one of the important members to protect family safety. However, in the process of use, some users found that the gas alarm had a false alarm.
Why? Under what circumstances will it lead to false alarm of gas alarm? Let's answer it for you!
The core of the gas alarm is the gas sensor, commonly known as "electronic nose", which is a unique resistance. When "smelling" the gas, the sensor resistance changes with the gas concentration. When the gas reaches a certain concentration and the resistance reaches a certain level, the alarm will give an audible and visual alarm to remind people of the gas leakage.
The false alarm of gas alarm is roughly affected by five factors: cooking, steam and moisture, too high flame of stove, too close distance between gas alarm and stove, and the service life of gas alarm has passed. In the case of brewing traditional Chinese medicine, heating beer and other alcohol, eggs and other food materials moldy and smelly, there is a large amount of smoke in the room, and the gas alarm itself is covered with a certain amount of dust and oil fume, the gas alarm may also give a false alarm.
How can users judge whether it is a false positive?
Users should turn off the gas and brush soapy water on the gas hose and connections for leakage. If bubbles are found, it is air leakage. If no leakage point is found, and cooking wine, vinegar and other spices are not used, but the alarm continues to alarm, or there is a problem with the alarm itself, contact the gas company immediately. If none of the above conditions occurs, the alarm is determined to be caused by the use of spices. The user can dispose of it by himself and continue to use gas. If the alarm is sent again, the user should also contact the gas company for disposal.
If you want to avoid false alarm of gas alarm during cooking, you should keep ventilation while cooking and use range hood at the same time.
If you want to judge whether the alarm works normally, you can check the self-test button on the alarm, and press it after recognition to give an audible and visual alarm.
How to deal with gas leakage?
When it is confirmed that the gas leakage occurs, the user should immediately turn off the gas source and evacuate the family for window ventilation. Remember not to make calls, switch lights, light lighters and other behaviors prone to sparks in the room filled with natural gas.
In order to avoid the occurrence of false alarm of gas alarm, in addition to avoiding heating food and beverage containing combustible gas in daily life, the gas alarm should be overhauled regularly to ensure normal function.
