Foreword
Bridge Navigational Watch Alarm System is to monitor the awareness of
the Officer of the Watch (OOW) and automatically alerts the Master or
another qualified OOW if for any reason the OOW becomes incapable of
performing the OOW's duties. This purpose is achieved by a series of
indications and alarms to alert first the OOW and, if he is not responding,
then to alert the Master or another qualified OOW. Additionally, BW508
also provide the OOW or other equipment with a means of emergency
calling for immediate assistance.

Setting
Select dormant period (Td)
In case that authorized person (Master) demands to select other dormant
period, person has to turn key switch S1 on BW508MAIN to position
“SET”. In this position only dormant period can be chosen by using rotary
encoder S2. Display is showing as follow
By turning rotary encoder S2 in clock wise direction, value is increasing.
By tuning rotary encoder S2 in counter clock wise direction, value is
decreasing. Possible main period value is limited between 3 and 12 min.
Step width is 1 min. By turning key switch S1 into centre position, system
accepts new value.
Adjust buzzer characteristics of 1st Stage Alarm
1st Stage Alarm internal buzzer’s sound characteristics can be adjusted.
By turning key switch S1 on BW508MAIN to position “SET”. Display is
showing as follow
Now push rotary encoder S2 on operating device BW508MAIN
repeatedly till the display is showing as follow
6
Now turn rotary encoder S2 to choose an adequate buzzer characteristic.
By pushing rotary encoder S2 display is changing and system accepts
adjusted value.
Adjust buzzer’s volume of 1st Stage Alarm
1st Stage Alarm internal buzzer’s sound volume (1~15) can be adjusted.
To adjust internal buzzer’s volume turn key switch S1 on BW508MAIN to
position “SET”. Display is showing as follow
Now push rotary encoder S2 on BW508MAIN repeatedly till the display is
showing as follow
Now turn rotary encoder S2 in counter clock wise direction to decrease
buzzer’s sound volume or in clock wise direction to increase sound
volume. By pushing rotary encoder S2 display is changing and system
accepts adjusted value.
Adjust time period of 2nd Stage Alarm
Adjustment could be necessary due to large vessel. Period can be
adjusted to max. 180sec (default value is 90sec), to allow sufficient time
7
for back-up officer and/or Master to reach bridge area before watch alarm
system is triggering 3rd Stage Alarm .
To adjust a.m. time period turn key switch S1 on BW508MAIN to position
“SET”. Display is showing as follow
Now push rotary encoder S2 on BW508MAIN repeatedly till the display is
showing as follow
Now turn rotary encoder in clockwise direction to increase time period
value or in counter- clock wise direction to decrease time period value.
System allows only value between 90 and 180sec. By pushing rotary
encoder S2 display is changing and system accepts adjusted value.
Adjust backlight of LCD and BW508R
If you want to adjust backlight of LCD and BW508R .Please turn rotary
encoder in clockwise direction to brighten, in counter- clock wise
direction to dim.

Operational mode
Automatic
System can be switched on by external systems (ship's heading or track
control system)
By turning key switch S1 left once. System is in AUTO mode. Auto
indicator is on. Display is showing as follow.
When ship's heading or track control system is activated, system’s
running is triggered. Count-down is active as shown on display as follow.
Manual ON
Authorized person (Master) switches on system by turning key switch S1
left twice. Count-down is active as shown on display as follow.
Manual OFF
Master is able to shut down system by turning key switch S2 left for longer
than 2 sec .
