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

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

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 .
