Heat Detectors are used to detect rises in heat in buildings or other premises as an early warning of fire as part of a fire alarm system.
A heat detector（that is what this article refers to residential heat detector) is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All residential heat detectors have this thermal lag.
In addition, residential heat detectors have two main classifications of operation, “rate-of-rise” and “fixed temperature”. The heat detector is used to help in the reduction of property damage. It is triggered when temperature increases.
