Smoke sensory alarm industry background
With the widespread application of bright fires, accidents such as explosions, poisoning and fire caused by fire have also occurred from time to time, which to some extent increased the unsafe and instability of the city to some extent. It is necessary to cause a large -scale fire unit and residents to choose a suitable smoke alarm device. Household smoke detection alarm is a small gas safety prevention product suitable for home use. It can effectively avoid vicious accidents such as explosions, fires, and poisoning caused by gas leakage, and has been widely used in most countries around the world.
The main function of the smoke sense alarm device
The smoke alarm detects the gas concentration of the gas through the gas sensor. When the concentration reaches the preset critical point, the smoke alarm will send a alarm signal to remind the relevant personnel to take safety measures.
The value of the smoke sensor adds the value of the voice function
1. Real voice alarm is more direct and real than simple sound alarm. When the fire occurs when the gas leaks occur, some models that only have a bee -lumator alarm device can only emit simple sound alarm sounds. The owner who purchased the installation heard that the alarm sounded that it was gas leakage and a fire broke out. But if the owner is not at home, there are only elderly people, children, or guests at home at home. They may not know what happened, which causes accidents. The alarm is added to the live -action voice alarm function, which can directly pass the gas leakage information, the fire of the fire, clearly and clear, allowing them to immediately know the gas leakage, or the fire and make proper disposal. (See typical voice 1)
2. Remind the alarm failure to eliminate hidden safety hazards.
After using the alarm for a period of time, there may be parts loss, which causes the alarm to not report to the alarm, and the owner does not know. In this case, the alarm is used in shape. When the alarm work is abnormal, if the voice can be continuously broadcast through the voice, the owner can repair or replace it in time to eliminate hidden safety hazards. (See typical voice 2)
