“JRC” BNWAS The Bridge Navigational Watch Alarm System (BNWAS) main purpose is to monitor the presence of watch officers and their alertness for early detection of unsafe sailing conditions. JRC’s BNWAS is also able to manage other onboard equipment alarms. When any connected equipment alarm is activated, the BNWAS displays a list of alarm information automatically. When the officer fails to acknowledge within pre-set intervals, visual and audible alarms will be generated in the wheelhouse and other crew spaces as necessary. JCX151/152
