The NSR NBW-1000 is a Bridge Navigational Watch Alarm System, abbreviated BNWAS. It is used on a vessel’s bridge to monitor the presence and alertness of the officer on watch. If no reset or activity is detected within the selected dormant time, the system activates visual and audible alarms in stages.
The system is designed for professional marine installations where international bridge watch and safety requirements must be met. The NBW-1000 features a 7 inch colour LCD, selectable alarm tones, log recording, routine test, emergency call and a data interface for BAM/INS integration.
The exact configuration may differ per vessel. Depending on the installation, reset units, alarm units, motion detectors, junction unit, cables and mounting materials may be required. Always check the quotation, class requirements, flag state rules and required system layout before ordering.
