Uni-Safe Electronics BW-800 Bridge Watch Alarm System BNWAS Unit

Maintain strict maritime safety compliance and safeguard your vessel with the Uni-Safe Electronics BW-800 Bridge Watch Alarm System (BNWAS). Purpose-built for the demanding environments of commercial cargo, logistics, and marine transport vessels, this system continuously verifies the alertness of the Watch Officer on the bridge. If the system detects a lack of interaction within a specified interval, it triggers a structured, multi-stage audible and visual alert sequence throughout the ship’s control centers to prevent navigation errors.

This specific unit features the reliable PCB Ver. 1A hardware architecture paired with Software Ver. 1 firmware layout, ensuring seamless integration with existing maritime sensor networks and voyage data loops.

Key System Capabilities

• Dual Monitoring Modes: Equipped with tactile controls to quickly switch operations between Manual and Auto configurations depending on vessel status.

• Integrated Key-Switch Security: High-grade physical key lock (ON / OFF positions) safeguards system parameters, preventing unauthorized tampering with safety timing cycles.

• Redundant Power Infrastructure: Built with a safe, decoupled power matrix featuring main supply paths (24Vdc, Pins 1-2) alongside a backup power layer (24Vdc, Pins 3-4).

• Multi-Stage Alert Routing: Designed to broadcast 24Vdc emergency signals progressively across three distinct audible/visual stages (Pins 19 through 24) to ensure rapid response.

• Voyage Data Recording: Features a dedicated VDR Data Output (NMEA) communication channel via Data+ and Data- terminals (Pins 15-16) for automated data logging.
