Fire Alarm System
A marine fire alarm system is a crucial safety feature on ships designed to detect and alert crew members of fire or smoke. These systems typically include fire alarm control panels, smoke detectors, heat sensors, manual call points, and alarm bells. When triggered, the system provides visual and audible alarms, allowing for quick response to potential fire hazards. Marine fire alarm systems are essential for ensuring the safety of the vessel and its occupants, complying with international maritime safety regulations.
