Alert priority and state
The
priority
of an alert indicates its severity. The BAM concept defines 4 priorities: Emergency Alarm,
Alarm, Warning and Caution. The LT-3100 system can raise alerts of the following priorities:
•
Warning
: Condition requiring immediate attention, but no immediate action by the bridge team.
Warnings are presented for precautionary reasons to make the bridge team aware of changed
conditions which are not immediately hazardous but may become so if no action is taken.
•
Caution
: Lowest priority of an alert. Awareness of a condition which does not warrant an alarm or
warning condition, but still requires attention out of the ordinary consideration of the situation or
of given information.
The shape and color of the BAM icon indicates the priority of the alert and the symbol inside indicates its
state as per Table 24 below.
