What is a 10 year sealed smoke detector?

 Recently, my uncle (my father's brother) called me. he said that he has to replace the battery of the smoke detector that is just use one year because that battery is get out of power. then my uncle asked me if I  can recommend him a smoke detector without replacing battery frequently. of course, our company sumring develops and sells these fire alarm products, I at once recommend a 10 year sealed smoke detector for my uncle.

speak of 10 year sealed smoke detector，what is it ？maybe someone do not about and Let me explain it.
10 year sealed smoke detectors are powered by sealed lithium batteries that have a life span of ten years. These alarms provide 10 years of continuous protection with no need to replace the battery for the life of the alarm.10 year sealed smoke detector provide up to 10 years of continuous service.

Although the 10 year sealed smoke detector can be used for 10 years, this is true, but we also need to take care of it and clean it from time to time to prevent dust and other things from entering the detector and affecting its function.

My uncle's family is now using the 10 year sealed smoke detector I recommended to him. Although it was only installed and used for a few days, he was very satisfied with the product appearance and performance. Really good!

Where is the application of fire heat detectors ?

We all know that smoke detectors and fire optical heat detectors are used to detect whether a fire has occurred. Smoke detectors monitor the concentration of smoke to prevent fires. Temperature heat detectors detect fires through changes in temperature. According to the different detection methods, the application places of the two fire detectors is still slightly different. Here we focus on the application places of optical heat detectors.

The fire optical heat detector has two alarm methods of rate-of-rise alarm and fixed temperature alarms. The temperature sense of the alarm at a fixed temperature of 57 degrees Celsius is suitable for all places where fire will occur. When the temperature reaches 57 degrees Celsius, it indicates that the fire has occurred or is occurring or is about to happen; It is noteworthy that Pay attention to the place where the temperature changes rapidly, it is better to choose a heat detector with Rate-of-rise alarm whose temperature rising rate>8℃.

Temperature-sensitive optical heat detectors: A temperature-sensitive maintenance area is 20 to 30 square meters
Where smoldering occurs or a fire cannot be reported in time, a optical heat detector should not be selected
Where one of the following conditions is met, a temperature-sensitive fire heat detector should be selected:
1) The optical heat detector is suitable for relative humidity often greater than 95%;
2) Smokeless fire;
3) There is a lot of dust;
4) Smoke and vapor stay under normal conditions;
5) Kitchen, boiler room, generator room, drying workshop, etc .;
6) Smoking room, etc .;
7) Other halls and public places that are not suitable for installing smoke detectors
