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.
