Heat detector

This is because heat detectors are designed to respond to elevated temperatures, which may occur too late to safely alert individuals in the event of a fast-spreading fire.

Portability, ease of installation, and excellent performance and reliability make this a good choice for residential fire protection when combined with the required smoke detectors.

[2] Each type of heat detector has its own set of advantages and limitations, making it important to select the appropriate device based on the specific requirements of the area being monitored.

This type of detector is generally less sensitive to rapid temperature fluctuations, making it more suitable for areas like large, industrial kitchens where ovens or other heat-producing equipment are frequently in use.

This type of detector is more sensitive to sudden temperature changes, making it better suited for areas that contain highly combustible materials.

Example Use Case: If a room filled with highly combustible materials is protected by a Fixed Threshold Detector, a rapidly-spreading fire could exceed the alarm threshold before the detector is triggered due to a phenomenon known as thermal lag refers to the delay that can occur in temperature measurements, which could cause a delay in triggering the alarm system.

In this case, the Rate-of-Rise Detector may be the preferred choice, as it would be more likely to detect rapid temperature increases and trigger an alarm in a timely manner.
