The alert system

The system will continuously check for danger situations and system faults while running.
Type of alerts
There are 3 alert types in the system:
• Alarms: This is the system's highest priority alert, activated when situation occurs that
might result in collision, or for conditions that critically effect the capability or
performance of the system. An alarm is accompanied by an audible signal (3 short signals
repeated every 7 seconds), and the alarm icon is flashing until the alarm is acknowledged.
• Warnings: This is alerts of lower priority, announcing conditions that could result in
unwanted system response or eventual failure if no action is taken. A warning is
accompanied by an audible signal (2 short signals repeated every 2.5 minute), and the
warning icon is flashing until the warning is acknowledged.
• Cautions: This is information about danger and caution objects that requires attention.
Caution alerts have no audible signal.
Alert notifications
When an alert is triggered, the alert appears in the Alerts panel. Alarms and warnings remain
in the Alerts panel until the reason for the alarm/warning is removed and the alarm/warning
has been acknowledged.
The alerts are displayed in a sorted order. The sort order is the severity (i.e. alarm before
warning), then age.
Alarms and Warnings have different states:
• Active - not acknowledged, not silenced
• Active - not acknowledged, silenced
• Active - acknowledged
• Active - responsibility transferred to another work station
• Rectified - not acknowledged
When a rectified alert is acknowledged it will disappear from the Alerts panel.
Cautions are not acknowledged, and they disappear from the system when they are rectified.
Cautions have therefore only an active state.
A number of related alerts are aggregated and shown in the Alerts panel as one single item
with the aggregation symbol next to the alert symbol. The aggregated symbol shows the
state as unacknowledged if at least one alert in the aggregated list is unacknowledged. Each
alert in the list has to be acknowledged individually.
The table below shows alert icon and behavior depending on if the alert is active,
acknowledged, transferred or rectified.
