IEC 62923-2-2018 pdf download.Maritime navigation and radiocommunication equipment and systems – Bridge alert management – Part 2: Alert and cluster identifiers and other additional features (IEC 62923-2:2018).
This part of IEC 62923 specifies standard alert identifiers and reserved cluster identifiers to be used when applying bridge alert management. The intent is to reduce the number of different identifiers used for similar alerts as much as possible.

4 Alert identifiers
4.1 Requirements
When defining alerts listed in Annex A, the corresponding alert identifiers defined in Annex A shall be used.
Alerts not listed in Annex A shall be assigned an alert identifier in the range 1 0000 to9999999.
The manufacturer shall provide a list of all alerts in the EUT, together with their assigned alert identifiers.
4.2 Method of test and required results
Confirm by inspection of manufacturer’s documentation that:
• if the manufacturer has defined alerts listed in Annex A, the corresponding alert identifiers are assigned as specified in Annex A; and
• if the manufacturer has defined alerts not listed in Annex A, the corresponding alert identifiers are assigned within the range 1 0000 to 9999999.
If applicable, cause up to 5 alerts listed in Annex A and confirm by observation that the reported ALF messages are indicating the appropriate identifier.
If applicable, cause up to 1 0 alerts not listed in Annex A and confirm by observation that the reported ALF messages are indicating an identifier in the range 1 0000 to 9999999.
5 Reserved cluster identifiers
5.1 Requirements
When defining clusters (see IEC 62923-1 ), the cluster identifiers defined in Annex B shall be used for their intended purpose. Only when the cluster identifiers defined in Annex B are not applicable, the free range of cluster identifiers as defined in IEC 62923-1 shall be used.
The manufacturer shall provide a list of all alerts in the EUT, together with their assigned cluster identifiers.
5.2 Method of test and required results
Confirm by inspection of manufacturer’s documentation that cluster identifiers are used as specified in Annex B. If the clusters defined in Annex B are not applicable, confirm by inspection that the cluster identifiers are used in the free range of cluster identifiers as defined in IEC 62923-1 .IEC 62923-2 pdf download.
