Where are heat detectors typically installed due to their activity?

Heat detectors are specifically designed to respond to the presence of heat rather than smoke, making them ideal for installation in environments where smoke detectors might produce false alarms. Therefore, they are commonly placed in unheated or dusty areas, such as garages, attics, and mechanical rooms. These locations might not have the consistent airflow that could lead to smoke accumulation, making smoke detectors less effective and possibly causing nuisance alarms.

In contrast, installing heat detectors in offices, classrooms, well-ventilated spaces, or lavish hotel lobbies could be counterproductive as these spaces are often more conducive to the production of smoke, where smoke detectors would be a better fit. Additionally, the presence of dust and other particulates can also lead to false alarms with smoke detectors; hence, heat detectors become a more reliable option in less controlled environments.
