The primary purpose of fire alarms is to detect fires and alert both occupants of a building and emergency responders. This detection is crucial because it allows individuals to evacuate the premises safely and promptly, reducing the risk of injury or loss of life. Fire alarms can sense smoke, heat, or flames, and once activated, they emit an audible or visual alert that informs people to take immediate action.

While notifying the fire department automatically can be a function of certain advanced fire alarm systems, this is not the broad primary purpose of fire alarms, as they mainly focus on detection and alerting. Additionally, the provision of lighting during emergencies, though important in mitigating dangers during an evacuation, is not a function attributed directly to fire alarms. Reducing the spread of smoke is a function of other fire protection systems, such as smoke barriers or ventilation control, and is not the primary role of alarms. Thus, the emphasis on detection and alerting is what underscores the vital role fire alarms play in fire safety protocols.
