A fire alarm system is a comprehensive safety network designed to detect fire early and alert occupants through audible and visual signals. It typically includes smoke detectors, heat detectors, manual call points, control panels, alarm sounders, and sometimes sprinkler activation interfaces. When a sensor detects smoke, heat, or flames, the system sends a signal to the control panel, which triggers alarms and may notify emergency services. Fire alarm systems can be conventional, addressable, or wireless, depending on the building s size and requirements. Proper installation, routine testing, and regular maintenance ensure reliable performance and enhance overall fire safety.
