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.
UNACKNOWLEDGED
Unacknowledged
R/W A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.
