What is the defining feature of a Rate-of-Rise Heat Detector?

The defining feature of a Rate-of-Rise Heat Detector is that it triggers an alarm with a rapid temperature change. This type of detector is specifically designed to monitor the rate at which the temperature in a given area increases. In scenarios where there is a fire, the temperature tends to rise rapidly, and this detector is sensitive to that quick change. When it detects a predetermined rate of temperature rise, it activates the alarm, allowing for a quicker response to potential fire hazards.

This is particularly beneficial in environments where smoke detectors might be too slow to react, as smoke can take time to build up and trigger a smoke alarm. In contrast, a Rate-of-Rise Heat Detector aids in catching potential fire events that exhibit a swift increase in temperature, ensuring a faster alert system for firefighting and evacuating purposes.
