A Heat Detector is an essential fire safety device that can recognize potentially dangerous increases in temperature in a given environment. Heat Detectors respond to changes in temperature, which means they can be effective in situations where smoke is not a key indicator of a potential fire hazard. Heat Detector can operate in one of two ways, either as a fixed temperature sensor, or as a rate-of-rise sensor. When a heat detector is activated its signals to alarm and fire alarm panels are sent so early action can be taken against fire hazards, preventing further damage to property. Early activation can save lives, property, and businesses from fire hazards.
