25. ALERT MANAGEMENT SYSTEM
(option)
25.1 What is an Alert Management System (AMS)?
An AMS warns the navigator, with audio-visual indications, when safety parameters
are violated or there is a failure of connected equipment. The AMS also transfers un-
acknowledged Alarm level alerts to the BNWAS.
The main functions of the AMS are
• Organize and track alerts that occur on the vessel. The AMS displays the alerts on
its HMI system and sounds a buzzer when an alert condition occurs.
• Acknowledge alerts.
• Transfer Alarm level alerts not acknowledged within 30 seconds to the BNWAS.
(The BNWAS then activates the Emergency Call to inform appropriate officers’
quarters of unacknowledged Alarms.)
25.2 System Configuration
The AMS is an integral part of the ECDIS. Refer to the system configuration for the
ECDIS.
25.3 Alert Definition, Priority and Category of Alerts
“Alert” is a generic name for an emergency, alarm, warning or caution generated by
an equipment connected to the AMS or the ECDIS.
Priority of alerts
Alerts have one of four priorities:
Priority of

and that immediate action must be taken. Emergency alerts are handled
the same as alarms.
Alarm Alarms indicate situations or conditions which require immediate atten-
tion, decision and (if necessary) action by the bridge team to avoid any
kind of hazardous situation and to maintain the safe navigation of the ship.
Warning Conditions or situations which require immediate attention for precaution-
ary reasons, to make the bridge team aware of conditions which are not
immediately hazardous, but may become so.

ordinary consideration of the situation or of given information.
