The function of a building's fire alarm system is to detect and alert occupants in the event of a fire or other emergency, allowing them to evacuate the building safely and quickly. The system typically includes smoke detectors, heat detectors, manual pull stations, audible and visual alarms, and communication devices that can inform emergency responders. It also may include suppression systems like sprinklers or gas suppression systems that can control or extinguish fires. The fire alarm system is an essential component of building safety and can significantly reduce the risk of injury or loss of life in an emergency.
