What is the primary function of a fire alarm system?

The primary function of a fire alarm system is to produce signals at one or more places on the premises. This involves detecting the presence of smoke, heat, or fire and alerting occupants through audible alarms, visual alerts, or both. The main purpose of these signals is to notify individuals within the building of a potential fire hazard, prompting them to evacuate safely and seek assistance.

A fire alarm system operates continuously to monitor the environment, ensuring that any signs of fire are quickly detected and communicated. By producing signals, it plays a critical role in the overall safety of the building's occupants, helping to minimize risk and response time in emergencies. This system is essential for initiating alerts that lead to timely evacuation and, ultimately, saving lives.

While other options involve necessary safety measures, such as guiding firefighters or managing HVAC systems, these functions are not the primary responsibility of the fire alarm system itself but can be influenced by its operation and the overall fire safety plan of a building.
