What is the function of a fire alarm system?

A fire alarm system is primarily designed to detect smoke or fire and provide warnings to building occupants. This system plays a crucial role in enhancing safety by alerting individuals to the presence of danger, thereby allowing them to evacuate the premises in a timely manner. The detection components, such as smoke detectors and heat sensors, are critical in identifying the early signs of a fire, and the alarm functions, like sirens or strobe lights, inform people to take action quickly.

Suppressing fires automatically, controlling fire escape routes, or illuminating the building during a fire—while important aspects of fire safety—are not the primary focus of a fire alarm system. Suppression systems, for instance, are designed to extinguish fires, whereas alarms serve to warn and notify. Fire escape routes are typically managed by building codes and safety regulations, and illumination systems are often separate backup safety measures. Therefore, recognizing the specific function of a fire alarm system is essential for understanding its role in fire safety and prevention.
