BNWAS BNWAS

The purpose of the Mega-Guard Bridge Navigational Watch Alarm System (BNWAS) is to monitor bridge activity and detect operator disability which could lead to marine accidents. The BNWAS monitors the awareness of the officer on the bridge and automatically alerts an on duty officer in case the officer on the bridge becomes incapable of performing his duties. In case the officer on duty does not respond, the other officers and other crew members are alerted by the BNWAS. The Mega-Guard BNWAS also includes an officer on duty selection and an officer call function. The BNWAS is operational whenever the ship's heading or track control system is engaged. The Master is allowed to disable the BNWAS and this function is protected by entering a personal code. A NMEA-0183 serial output is available for connection to the VDR. The Mega-Guard BNWAS is powered by two 19~32VDC power supplies: one main supply and one back-up supply.
