- Heat detectors work by detecting changes in temperature1234. There are two main types:
- Fixed-temperature heat detectors: Trigger an alarm when a specific temperature threshold is reached.
- Rate-of-rise heat detectors: Detect rapid temperature rise and trigger an alarm.

To view the original source information, use the "Learn more" links.A 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 heat detectors have this thermal lag.en.wikipedia.org/wiki/Heat_detectorHeat detectors work by detecting changes in temperature or reaching a predetermined temperature threshold, which triggers an alarm. There are typically two types of heat detectors: fixed-temperature heat detectors and rate-of-rise heat detectors.firefighterline.com/what-are-heat-detectors/Put simply, a heat detector - or heat alarm - is a device that's used to detect any substantial increase in temperature which may indicate a fire is about to break out. If there is a fire in the vicinity of the alarm, the convected thermal energy from the flame raises the temperature of a heat-sensitive element in the heat detector.www.sentinelfire.co/what-is-a-heat-detector/Heat detectors are fire detection devices that sense heat produced by combustion. They can trigger an alarm when a rapid temperature-rise is detected, or a preset temperature is reached.www.globalspec.com/learnmore/building_constructi… - People also ask
