The primary function of a fire alarm system is to detect smoke or fire within a building and alert occupants to evacuate safely. This system comprises various components such as smoke detectors, heat detectors, and alarm notification devices that work together to provide early warning in the event of a fire. By alerting occupants, the fire alarm system helps ensure that individuals can vacate the premises promptly, minimizing the risk of injury or loss of life.

While it is crucial for fire alarm systems to notify local authorities in certain configurations, that is not their primary function. The role of extinguishing fires automatically is typically fulfilled by fire suppression systems, like sprinklers, rather than alarm systems. Monitoring environmental conditions may be part of other systems, but it does not encompass the core responsibility of a fire alarm system. Therefore, the ability to detect and alert occupants is foundational to the purpose of fire alarms, emphasizing their critical role in fire safety and protection.
