What is the main purpose of a fire alarm system?

The main purpose of a fire alarm system is to detect fire incidents and alert both the occupants of the building and emergency responders. This system is essential for ensuring the safety of individuals, allowing them to evacuate in a timely manner and notifying emergency services to respond. Fire alarm systems utilize various detection technologies such as smoke detectors and heat sensors to identify signs of a fire.

While controlling sprinkler systems, providing light during an emergency, or extinguishing fires may be functions of other fire safety equipment, they do not encompass the primary role of a fire alarm system. The core function remains centered on detection and alerting, which is critical for saving lives in the event of a fire emergency.
