This article covers the basics of heat detectors and different types of heat detectors. It compares fixed temperature heat detectors with rate of rise heat detectors, highlighting the differences between them.

Definition: A heat detector is a device that operates based on the detection of heat or temperature.

The following are the main types of heat detectors:

  • Fixed Temperature Heat Detector
  • Rate of Rise Heat Detector

Difference Between Fixed Temperature Heat Detector and Rate of Rise Heat Detector

The following section describes both types of heat detectors and their key differences.

  • Fixed Temperature Heat Detector: This type of detector continuously monitors the air temperature and triggers an alarm when the air temperature exceeds a pre-set temperature threshold within the device.

  • Rate of Rise Heat Detector: This type of detector senses the rate at which the air temperature is increasing in its vicinity. It triggers an alarm when the temperature rises faster than a pre-set rate with respect to time.
