The JRC JCX-161 BNWAS (Bridge Navigational Watch Alarm System) main purpose is to monitor the presence of watch officers and their alertness for early detection of unsafe sailing conditions. The JCX-161 incorporates many display modes readily available on a highly visible 4.5-inch LCD display. Besides the display being fully dimmable and having backlit keys, it features dual LED backlight (white and orange), making it easy to operate in various light settings on the bridge.

The system has a range of standard (and optional) possibilities to reset the timer for visual indication and audible alarm. On the display you can reset the alarms and a maximum of 6 reset buttons can be connected, regardless of normal or waterproof type. Movement detection by motion sensor resets the alarms but also when the BNWAS is connected to other navigation equipment such as radar (JMA-9100) or ECDIS (JAN-901B), the alarm is reset when the officer physically operating the controls.
When any connected equipment alarm is activated, the BNWAS displays a list of alarm information automatically. When the officers fails to acknowledge within pre-set intervals, visual and audible alarms will be generated in the wheelhouse and other crew spaces as necessary.
BNWAS was mandated for all new build passenger ships and cargo ships above 150GT constructed on and after 1 July 2011 and is being phased in for existing ships over the coming years to meet IMO requirements.
