What is the function of a fire alarm system?

A fire alarm system is primarily designed to detect the presence of smoke, heat, or flames and to alert building occupants of a fire emergency. This system plays a crucial role in ensuring safety by providing early warning, so individuals have the necessary time to evacuate the premises or take appropriate actions. It typically includes alarms, smoke detectors, and sometimes visual indicators to ensure that all occupants, including those with hearing impairments, are alerted promptly.

The focus of a fire alarm system is on detection and notification rather than suppression; it is not intended to extinguish fires automatically, provide medical instructions, or connect directly to emergency services. The main purpose remains centered on alerting occupants to evacuate and seek safety.
