Sum-Alarm and Sum-Warning Message
In contrast to the common alarms the ARPA- and the AIS Alarm or Warning
massages are combined in six groups:
-- Lost Target Warning AIS
-- Lost Target Warning ARPA
-- TCPA/CPA Alarm AIS
-- TCPA/CPA Alarm ARPA
-- Guard Zone Alarm AIS
-- Guard Zone Alarm ARPA
The purpose of the sum-alarms or warnings is to minimize the number of alarm
messages in the alarm readout display and to minimize the acknowledgement
effort for the operator.
In case several alarms of one type occur (see groups above), they are
displayed as one single alarm message in the alarm readout display.
Number, date and time stamp of the last received alarm is displayed.
The message text is the same for each alarm message of the group.
Situation: e.g. TCPA/CPA ARPA (message text)
first alarm [ 1 ] RADAR ALARM
2013--12--03 13:36:16

TARGET (S)
second alarm [ 1 ] RADAR ALARM
