25.7
How an Alert is Transferred to the BNWAS
Alerts are transferred to the BNWAS in the following sequence.
Note: For a DNV class vessel, only category A alerts are transferred.
1) An alert generated by an equipment connected to the AMS is transferred to the
BNWAS if it is not acknowledged within 30 seconds.
2) The BNWAS sends the Emergency Call to applicable Cabin Panels in living quar-
ters and general quarters, to inform personnel of an unacknowledged alert.
To stop both the Emergency Call and the transfer of the alert, do as follows:
• Category A alert: Acknowledge the alert at the equipment that generated the alert.
• Category B alert: Acknowledge the alert at the equipment that generated the alert
or the AMS.

Note: The transfer of alarms can be stopped (when in port, etc.) by setting the system
in standby. See section 1.4 for details.
