 System parameters

 System interfaces

The JHD01-BNW bridge navigation watch alarm system (BNWAS) is used to monitor the alertness of the bridge watch officer, and you can use the three operational modes to select one of them. If you choice the “manual” operational mode, the system will enter the running status directly, when you choice the“Auto”mode, the system will be activated by the working signal of auto pilot system.
