DM BNWAS

The Danelec DM BNWAS is a three‑stage Bridge Navigational Watch Alarm System that monitors bridge activity and alerts if the watchkeeper becomes unresponsive, meeting IMO SOLAS requirements. The supplied category identifies the equipment as INS), and it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that listed role, its primary purpose is to provide navigation, position, heading, speed, depth, traffic or bridge-management information according to the listed category. Radar, ECDIS, gyrocompass, GNSS, speed log, echo sounder and integrated bridge systems use different sensing principles, so calibration and interfaces must match the actual installed equipment. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states capacity: 3-stage alarm. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
