1INTRODUCTION :
The ALPHA BNWAS Bridge Navigational Watch Alarm System is flexible in
use and complies to the latest International regulations (Approved
according to IMO Resolution 128(75)). This BNWAS system is applicable
on all sea-going vessels.
The ALPHA BNWAS has an internal buzzer and at the same time a relay
for an audio alarm at the bridge. Also there are 2 relays contacts to call
the officer and to call the crew.
Between the “call officer” and the “call crew” stage the time is adjustable
from 90 to 180 seconds. This adjustment can be made by a 16-position
switch which is located next to the big chip on the print.
Normally this switch will be in the default zero position (90 sec.) This time
may be adjusted to the maximum time of 180 seconds when the watch
alarm is placed on for example a large passenger vessel.
The status of the relays and buzzer are visualized by the three red LED’s
on the top of the front panel. When the watch alarm is malfunctioning or
the power supply is not connected, the watch alarm will generate an
alarm message on your monitoring system by opening the malfunction
contact.
All LED’s except for those of the “call officer” and “call crew” are dimmable
in five stages which can be performed by holding the reset button for
more than 1 second. The reset button is tamper proof because the time
system will only recover on the rising edge of the internal and external
reset input. The run led will flash when the watch time is running and is
also available on the Alarm Buzzer or Remote Reset Button. The BNWAS
control unit is provided with an emergency call function, this mode can be
activated when immediate help is needed on the bridge.
The ALPHA BNWAS is Lloyd’s register approved.

3OPERATION
The ALPHA BNWAS is easy to operate by the push buttons on the front
panel of the watch alarm. Adjustments can be made to time and
auto/on/off when the key switch is in its vertical position. In this position
the key cannot be removed.
When the watch alarm is in the ON position or
the auto pilot is on duty, the watch time is
between 3 or 12 minutes. When the key is in
the horizontal position no changes can be made
to time or auto/on/off settings.
When the time exceeds the selected time limit,
the reset LED will begin flashing. After 15
seconds the internal buzzer or the bridge siren
will sound. The Officer of the Watch has to
respond within 15 seconds by pushing the reset
button on the front panel or optional remote
reset button.
If he or she fails to do so the resting Officer will
be alarmed in his cabin via the Alarm Buzzer. If
there is still no response the stage 3 call crew
will be triggered after 90–180 seconds.
When the emergency mode is activated by pushing the emergency
button on the front panel or the optional external emergency button
somewhere on the bridge the watch alarm switches to “call officer”
stage, and when no response the “call crew” will trigger.

The AlphaBNWAS is easily operated by the buttons on the front panel.
Changes to time and on/auto/off mode can only be made when the key
switch is in the vertical position. The key cannot be removed when the
key is in the vertical position.
The 3 to 12 minute timer can be adjusted by pushing the time select
button. The on/auto/off mode can be selected by pushing the on/auto/off
select button. Activating the AlphaBNWAS will start the 3 to 12 minute
timer until it exceeds. The “reset” LED will start blinking and the internal
buzzer will sound for half a second giving a pre-alarm.
After 15 seconds the internal buzzer will pulsate continuously and the
relay contact for the (optional) bridge siren will sound.
If the officer on the bridge does not respond by operating the reset button
within 15 seconds, the backup officer will be alarmed and “call officer” LED
will light.
When the backup officer does not respond within the preset time (90-180
seconds) the entire crew will be notified by activating the general alarm.
This last stage can be adjusted with the 16-position switch (0-F) behind
the removable front panel.
The time is adjustable from 90 to 180 seconds in steps of 6 seconds
(0=90 , F=180 seconds). When the “Emergency” button is operated the
AlphaBNWAS will switch to “call officer” stage without activating acoustic
signalling on the bridge. The LEDs on the front panel can be dimmed by
holding the reset button for a few seconds.
