BNWAS Basic is a full-featured Bridge Navigational Watch Alarm System as required by IMO Carriage requirements. The BNWAS Basic was designed to fulfill all of the requirements at a minimum cost level. It is optimised for retrofit installations and can be installed by the crew providing basic electrical experience. The system is suitable for vessels of all sizes.

The BNWAS is a low-cost monitoring system of "Navigator Fitness" fulfilling the latest IMO requirements.

By monitoring bridge activity via the user interaction and physical movement in the bridge area (optional motion sensor), the system can detect operator disability and alert backup navigators to the bridge area, thus participating in the safe operation of the vessel to help avoiding accidents.

Backup navigators can be alerted (following rules and regulations), i.e. captain's cabin can be alerted and different officer's cabins can be selected to be on duty for second backup call alarms. All control and handling of alarm system, backup call functions and timer settings are performed at the Watch Alarm Panel WAP 2012 located centrally in the bridge console.
