Vesper External smartAIS Alarm & Mute Switch Kit f/WatchMate XB-8000

The Vesper External smartAIS Alarm & Mute Switch Kit for WatchMate XB-8000 is a marine-grade networked alert system designed to extend collision avoidance and Man Overboard detection beyond your primary display. This external alarm module activates independently of mobile device status, ensuring audible warnings reach crew on deck or in engine spaces where connectivity may be unreliable. The kit installs remotely from the primary WatchMate unit, placing acoustic alert capability at strategic locations—helm station, bridge, or crew quarters—critical for operational awareness in high-traffic anchorages or congested shipping lanes.

The system triggers on three distinct smartAIS threat vectors: collision risk detection when the WatchMate XB-8000 calculates intercept course with tracked targets, anchor drag alert when vessel position drift exceeds programmed parameters, and MOB (Man Overboard) activation for emergency crew recovery operations. The dual-signal design—simultaneous smartphone notification plus hardwired alarm—eliminates single-point failure in the alert chain. Mute switch functionality prevents nuisance alarms from disabling the system entirely, allowing crew to silence false positives while maintaining detection and re-alert capability. Compact form factor (2×2×2 inches, 0.1 lbs) permits flush mounting in cabin bulkheads, console soffits, or open galley spaces without occupying significant real estate.

This kit suits cruising sailboats, commercial fishing vessels, and offshore power vessels where crew distribution across multiple compartments prevents reliance on single-point alert systems. Operators running extended passages, anchoring in busy harbors, or operating short-handed benefit from distributed alarm architecture that guarantees critical warnings reach personnel regardless of mobile device presence, battery state, or signal strength. The external module integrates with existing Vesper WatchMate XB-8000 installations without replacing the primary unit.
