A ‘heat detector is a fire alarm device designed to respond when the connected 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.

Rate-of-Rise (ROR) heat detectors operate on a rapid rise in element temperature of increase per minute, irrespective of the starting temperature. This type of heat detector can operate at a lower temperature fire condition than would be possible if the threshold were fixed. It has two heat-sensitive thermocouples or thermistors. One thermocouple monitors heat transferred by convection or radiation. The other responds to ambient temperature. Detector responds when first’s temperature increases relative to the other.
