Block Alarm
The block alarm is used for all configuration, hardware,
connection failure or system problems in the block. The cause of
the alert is entered in the subcode field. The first alert to become
active will set the "Active" status in the "Status" attribute. As soon
as the "Unreported" status is cleared by the alert reporting task,
another block alert may be reported without clearing the "Active"
status, if the subcode has changed.
