The Furuno BR500 BNWAS monitors the watch officer's presence through watch safety system functions. A watch officer is required to press the button on a Timer Reset Panel or to operate navigation equipment (i.e.: ECDIS, Radar, etc.) at certain preset intervals. If the officer fails to press the button, operate connected equipment or trigger optional motion sensors within preset intervals, visual and audible alarms will be generated in the wheelhouse. If the officer doesn't respond to the alarm, the BR500 transfers the alarm to the Cabin Panels installed in other sections of the vessel in order to inform backup officers of the watch officer's incapacity.
