1.1 Functions
The system is a Bridge Navigational Watch Alarm System (BNWAS) consisting of a control unit, a
display unit, buzzer units, and reset devises. It is designed to prepare for any contingency in
which a duty officer is disabled to fulfill his duties due to a nap, health problem, or other reason.
Upon such an event, the system alerts other officers.
1.1.1 Purpose of the system
The purpose of the Bridge Navigational Watch Alarm System (BNWAS) is to monitor the motions
of the duty officer in the bridge and detect any his behavior disorder that may lead to a marine
accident.
To achieve the purpose, dormant period is set. If no reset operation is performed within the
dormant period, the system recognizes that the duty officer cannot fulfill his duties and outputs an
alarm in the bridge. If no response is given even after that, it alerts the captain or other qualified
officer for its situation.
1.1.2 Operational mode
BNWAS includes the following operation modes.
1) Auto Mode (Automatic mode)
While the ship's heading control system or the track control system is active, the
dormant period count down operates automatically. When their systems are not
activated, the countdown will not operate.
2) Manual On
The dormant period countdown operates continuously.
3) Manual Off
The dormant period countdown does not operate.
The Manual Off only stops the dormant period countdown. It operates the emergency
call, other call functions, and the bridge alarm transfer function.
Except in anchorage or in-bay navigation, operate the unit with “Manual On”.

7ZPNA4321
1.1.3 Operation sequence of displays and alarms
Depending on the operation mode, the unit is activated and the dormant period countdown
starts. When the countdown ends, the following displays and alarms are triggered.
1) Visual Indication
At the end of this dormant period, the alarm system initiates a visual indication on the
bridge. The visible display is a blinking manner.
2) First Stage Bridge audible alarm (1st Stage Bridge audible alarm)
If not reset within 15 seconds since the visual indication is initiated, the BNWAS
additionally sounds a 1st stage bridge audible alarm on the bridge.
3) Second Stage Remote audible alarm (2nd Stage Remote audible alarm)
If not reset within 15 seconds since the 1st stage bridge audible alarm is initiated, the
BNWAS additionally sounds a 2nd stage remote audible alarm in the back-up officer's
and/or Master's location.
4) Third Stage Remote audible alarm (3rd Stage Remote audible alarm)
If not reset within 90 seconds (which can be set 0s, or between 90 ~ 180s) since the 2nd
stage remote audible alarm is initiated, the BNWAS additionally sounds a 3rd stage
remote audible alarm at the locations of further crew members.

1.2 Features
1.2.1 Versatile functions with standard configuration
1）BNWAS function
When dormant period are measured, and the confirmation is not done, warning is
output with the visual indication and the alarms according to the sequence of 1.1.3.
2）Support of emergency call function and bridge alarm transfer function
The emergency call function is offered without optional equipment. The bridge alarm
can transfer an unacknowledged alarm with the serial interface that uses the
IEC61162-1 ALR sentence.
1.2.2 Various reset devices and number of inputs
1) Reset devices
A maximum of 6 pushbutton reset devices (NCJ-895 and NCJ-896) can be provided so
that the dormant period can be reset within 15 s in anywhere since the visual indication
starts. The reset function is equipped also in the LCD Display unit (NWZ-4650).
2) Motion sensor type reset device (option)
The motion sensor (NYG-5) which performs automatic reset by human presence and
motions can be installed.
3) Reset by external unit
The system supports the reset signal from other navigational equipment. The reset
signal can be input via. an IEC 61162 serial interface or a contact input.
1.2.3 Output to external device
1）System Failure output by contact signal
The system can output the System Failure to CAS by contact signal.
2）VDR output by serial interface
The system can output machine status or alarm situation to VDR by the serial interface
using the IEC61162-1 ALR sentence.
