What is the role of a heat detector in fire safety?

The role of a heat detector in fire safety is primarily to monitor temperature. Heat detectors are designed to sense changes in temperature within a specific environment. When the temperature rises to a set threshold—indicating a potential fire condition—the detector activates an alarm. This capability is crucial because it allows for early detection of fires, giving individuals time to escape and ensuring that emergency services can be alerted promptly.

While other devices may detect smoke or provide audio alerts, the unique function of a heat detector focuses on temperature changes related to fire. The activation of sprinklers is typically the responsibility of a different system, such as a fire suppression system, which may be activated based on various triggers, including the signals from heat detectors but also smoke detectors and manual activation.
