25.7 How an Alarm is Transferred to the BNWAS
Alarms are transferred to the BNWAS in the following sequence.
Note: For a DNV class vessel, only category A Alarms are transferred.
1) An Alarm 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 Alarm.
To stop both the Emergency Call and the transfer of the Alarm, do as follows:
• Category A, Category C Alarm: Acknowledge the alert at the equipment that gen-
erated the Alarm.
• Category B Alarm: Acknowledge the alert at the equipment that generated the
Alarm or the AMS.
Note: The transfer of Alarms can be stopped (when in port, etc.) by setting the system
in Silent mode. See section 1.4 for details.
