Heat detectors are used in rooms where smoke detectors are unsuitable, for example, where smoke normally occurs. The heat detector reacts when the temperature sensor in the detector reaches a certain temperature. The detector can either react if the temperature reaches a certain level, or by rapid temperature rise over a given period.
