The core component of the household gas alarm is the sensor. A gas sensor is installed inside the gas alarm device. When gas is detected (the gas concentration is 5% of the lower explosion limit of natural gas, that is, the concentration of natural gas in the air is 0.25%), the sensor and the alarm inside the alarm. The central control system will issue "sound and light" alarm instructions, the alarm indicator lights will light up and flash, and intermittent alarm sounds will be issued.
The leakage of combustible gas is not only harmful to human health, but once the concentration of combustible gas in the air is too high, it will cause more serious consequences such as fire in case of an open flame. Therefore, it is very important to do a good job in preventing the leakage of flammable gas.
An effective way to prevent household flammable gas poisoning is to install household gas alarms. When the gas in the air rarely reaches the dangerous value or there are other suspicious gases, the detector will issue an alarm, and the linked gas shut-off valve will automatically cut off the gas.
It is very necessary to install a gas alarm in the kitchen. Don't wait for the danger to come before thinking about installing it, especially if there are elderly people at home. Buying a gas alarm is to care for the elderly. At present, there are some gas alarms on the market that are not of good quality. Therefore, when buying a gas alarm, you must choose a well-known and high-quality product. The gas alarm can be linked with the solenoid valve and start the exhaust fan. When the danger comes, it can alarm and relieve the danger. To ensure the safety of the home environment and maintain the safety of life and property, household gas alarms are worthy of promotion.
