The component shown in the illustration would be installed in which of the following types of fire detection systems? Illustration SF-0004

Correct Answer: Option A — Fixed temperature

Fixed temperature fire detectors utilize a bimetallic strip or a fusible link that melts or deforms at a specific calibrated temperature. Unlike rate-of-rise detectors, which respond to rapid temperature changes, these devices are designed to trigger an alarm only when the ambient temperature reaches a predetermined threshold.
