Description

Dual LED backlight

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.

Accessories

Along with our introduction of the new JCX-161, we introduce new accessories that compliments our unified design approach.

Calling functions

Also available on the unit is the emergency call function which triggers all devices (buzzers) to activate. In addition, officer call also available which provides audible notice for backup officer at 2nd stage alarm.

Operation modes

The unit has automatic and manual operation modes. While the ship’s heading TCS or HCS is active, the set period countdown operates automatically. In case you turned on the system to operate manually countdown operates continuously. When ship is in anchorage the unit can be turned off, however emergency calls, other call functions and bridge alarm transfer are still operable.

Operation

Manage other alarms

 

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.

Connect to VDR

 

The system can output system status and alarm situation to the VDR through serial interfacing using the NMEA0183 ALR sentences.

IMO

 

BNWAS will be mandatory for all new build passenger ships and cargo ships above 150GT constructed on and after 1 July 2011 and will be phased in for existing ships over the coming years.

 

Long LCD life

The LCD has a life span of 50, 000 hours that equals roughly 6-years of continuous, 24/7 operation – regardless of the LED backlit color selected.
