Restoring a check-in group
Typically, when all members of the check-in group respond
within the time-out period (as established in the 3-SDU), the
Function Active, Check-In Activate event restores automatically
and no other events associated with the check-in group will be
reported. However, if any member fails to respond within the
time-out period, the following sequence must be enacted to
restore the check-in devices to the group at the conclusion of the
time-out period. Otherwise, EST3 will consider those devices as
being out-of-service for all subsequent check-in group
activations.
Note: The check-in group time-out period must be expired and
member devices must have failed to respond. Otherwise,
activating member devices under otherwise normal conditions
will trigger an emergency alarm event.
To restore devices that did not respond within the time-out
period:
• Activate and restore each check-in device that did not
respond within the time-out period.
