According to the service life requirements of electronic products, it is generally stipulated that it is 8 years, and if the daily maintenance is good, the service life will generally exceed this time.

Generally, there are no special provisions, and the stability of the fire alarm system has a lot to do with the quality of construction. Construction, daily maintenance in place, generally 20 years of use is no problem. When the middle does not exclude environmental factors, aging of field equipment, human reasons and other burning out of the host.

There is no specification that clearly stipulates the service life of the alarm host, and the daily maintenance has a great impact on the service life of the alarm host, as well as the aging of the line, short circuit, etc.

There is no rule that it can be used as long as it is functional.
