A Heat Detector is a fire-detection device that responds to a fixed temperature threshold or to a rapid rate of temperature rise rather than to smoke. In data centers it supplements smoke detection in areas prone to nuisance alarms or where smoke sensing is impractical, though it typically activates later in a fire's development than smoke-based devices.
