What is the difference between a smoke alarm and a heat alarm?

A smoke alarm and a heat alarm are two different types of fire detectors with distinct functionalities. A smoke alarm is designed to detect the presence of smoke particles in the air, while a heat alarm is specifically engineered to detect rising temperature levels. Smoke alarms are highly effective at detecting early signs of fire, even before the presence of flames, by sensing smoke particles and triggering an audible alarm to alert occupants. On the other hand, heat alarms are particularly useful in environments where smoke may be present under normal circumstances, such as kitchens or garages. Heat alarms activate when the surrounding temperature exceeds a certain threshold, providing rapid response in situations where smoke is not necessarily an immediate warning sign. Overall, both smoke alarms and heat alarms play significant roles in ensuring prompt fire detection and enhancing overall safety in different types of settings.
