Product Description
MSA-1ZQ Watertight Door Alarm Unit
Product Introduction
The Marine Watertight Door Alarm Unit is a dedicated, self-contained control module engineered to manage and signal the operational status of a vessel's watertight doors. As a critical node in the ship's overall safety architecture, this unit is responsible for initiating clear, mandatory audible and visual alarms (typically a rotating red beacon and a distinctive buzzer/horn) at the door location before any automatic or remote closing sequence begins. This direct, localized warning is essential to prevent crew entrapment and injury. Built to withstand the harsh marine environment with corrosion-resistant materials and high IP ratings, the unit often integrates seamlessly with the ship's central watertight door control panel and general alarm system. It ensures strict compliance with SOLAS regulations (particularly Chapter II-1) and classification society standards, providing reliable, standalone functionality for the door it serves.
