The main detection unit of the linear temperature fire detector is the temperature sensing cable. The temperature sensing cable is a heat sensitive, special cable that can detect over temperature within its length range once the ambient temperature reaches the temperature cable rating Of the operating temperature, the cable type linear temperature fire detector will produce an alarm.

Cable type linear temperature fire detectors, with unique advantages over other types of detectors, are ideal for use in high-risk flammable areas and a wide range of business environments, especially with installation difficulties and harsh and environmental Conditions, better reflect its superior performance. But the temperature of the cable on the use of different manufacturers have different claims, some say that can be used for 5 years, some said that can be used for 8 years, and even some manufacturers claim that the temperature cable can be used for 20 years, on the temperature of the cable The use of life was a different phenomenon, and as a consumer in terms of the general lack of experience in judging the experience of the life of the temperature cable, the manufacturers of different claims tend to cause confusion, if the temperature of the cable is not easy and easy to use The replacement of the replacement, will waste a lot of manpower and material resources; the contrary, if the temperature of the cable has been expired and not replaced in time, often the introduction of insecurity, once the temperature of the cable area of the use of fire leakage, will give the country Of life and property caused significant losses.

We found that the production of temperature sensing cable raw materials in the course of the use of aging phenomenon, so with the linear temperature fire detection of the use of the increase in the temperature of the original design parameters of the cable will change, will affect the temperature cable The alarm performance. My company after long-term application experience, and through the use of temperature box to speed up the simulation of temperature sensor aging test found that 10 years or so for the temperature of the aging of the aging period, that is, about 10 years of use of temperature cable aging will intensify Re-use, should be replaced to deal with.

The above description of the use of linear temperature fire detectors is provided for informational purposes only, and its service life is closely related to its use, and these require comprehensive consideration.
