What type of detector is a continuous-loop fire detector categorized as?

A continuous-loop fire detector is categorized as an overheat detector. These detectors are designed to monitor temperature along a length of sensing cable. When the temperature along the loop exceeds a predetermined threshold, it indicates that there may be a fire present due to excessive heat being generated.

Effective operation is achieved as the continuous loop can provide a real-time assessment of temperature changes across the area being monitored. Since it can detect gradual increases in temperature typically associated with smoldering fires or hot spots that could lead to combustion, it is particularly suited for environments such as power plants where equipment can rapidly heat up and present a fire risk.

In contrast, other types of detectors focus on different methods of detection, such as smoke, which identifies products of combustion, or flame detectors that specifically recognize the light emitted by flames. Understanding the specific function of continuous-loop fire detectors in detecting overheat conditions allows for more effective fire prevention and response strategies in critical areas.
