Which fire detection system is designed specifically to respond to smoke?

The smoke detector is designed specifically to respond to the presence of smoke in the environment. It utilizes various technologies, such as ionization or photoelectric sensing, to detect smoke particles in the air. When smoke is present, it triggers an alarm to alert occupants of a potential fire hazard, allowing for timely evacuation and response.

In contrast, the heat detector is focused on detecting changes in temperature rather than the presence of smoke. Gas detectors are designed to identify specific gases, such as carbon monoxide or flammable gases, rather than smoke. Flame detectors respond to the infrared or ultraviolet radiation emitted by flames, making them suitable for outdoor or industrial applications where fire is expected but not for smoke detection in standard environments. Thus, the choice of a smoke detector is the most appropriate for detecting smoke specifically.
