What is the primary function of smoke detectors?

The primary function of smoke detectors is to detect the presence of smoke and provide a warning to individuals in the vicinity. When smoke particles enter the detector, it activates an alarm that alerts occupants of the potential danger, allowing them valuable time to respond appropriately—whether that means evacuating the building or taking other safety measures.

While smoke detectors play an essential role in fire safety, they do not directly alert firefighters, control building alarms, or notify the fire department automatically. Their main purpose is to serve as an immediate warning system for those present, enhancing personal safety and facilitating a quicker response to fire emergencies.
