What type of alarm is triggered by high temperatures indicating a fire?

A heat alarm is specifically designed to detect increases in temperature, which can be indicative of a fire. Unlike smoke alarms that respond to the presence of smoke particles in the air, heat alarms assess the temperature within an environment. When the temperature reaches a certain threshold, typically due to the heat generated from a fire, the heat alarm activates to alert occupants of the potential danger.

This type of alarm is useful in areas where conventional smoke alarms might produce false alarms, such as kitchens or garages, where cooking or machinery may generate normal smoke or steam. The careful monitoring of temperature helps ensure that fires are detected promptly while minimizing unnecessary alerts.

In contrast, smoke alarms are reliant on the presence of smoke, which can lead to false alarms caused by harmless activities like cooking, while fire alarms can refer to various alarm systems that respond to either smoke or heat, making heat alarms a more specific and suitable choice for the scenario described. A warning alarm could refer to any alert system without specifying the type of danger, which makes "heat alarm" the most precise answer in this context.
