The Marine Watertight Door Alarm System is a critical safety and operational control system designed for modern vessels. It provides audible and visual alerts prior to and during the closure or opening of power-operated watertight doors. This system ensures crew safety by preventing accidental entrapment and is essential for compliance with SOLAS regulations. It features robust, corrosion-resistant components for reliable performance in harsh maritime environments, offering both local and bridge console warnings to enhance situational awareness during emergency drills and actual events.
