What is the primary function of a fire alarm system?

The primary function of a fire alarm system is to alert occupants of a fire emergency. This life-saving role is crucial, as timely notification allows individuals in a building to evacuate safely and quickly in the event of a fire. Fire alarm systems are designed to detect smoke, heat, or flames and produce audible and/or visual signals to warn people of potential danger.

While preventing fires, notifying the fire department, and controlling HVAC systems are important aspects of overall fire safety and building management, these functions are not the primary objective of a fire alarm system. The focus is on early detection and alerting occupants to minimize risks and protect life.
