During this time if an existing override schedule becomes active (the door
programmed override schedule), then the door will remain locked.
Authorised PIN/card users can open the door as normal.
An unlock command issued from management or configuration software will
unlock the door and cancel the start action.
An open door or timed open door command issued from management software
will perform the function but will not cancel the start action.
Cancelling a start action
A start action that is running can be cancelled by overriding its operation from
management or configuration software. For example:
•
Where a start action is holding the door unlocked, the action can be cancelled
by locking the door via management or configuration software. The
cancellation is only for the current iteration of the door schedule and future
iterations will still operate.
•
In the case where the door is being unlocked by the start action and an
unlock command is sent from management or configuration software, the
action will continue to operate and is not affected.
When a start action is cancelled, the end action is not performed. The door will
return to its default state (locked) if no other override or macro is active.
If a start action that enables the door is cancelled then the door will remain
enabled. Similarly, if a start action that disables the door is cancelled then the
door will remain disabled.
Deleting a door schedule
When deleting an active door schedule, the start action is immediately cancelled
and the cancellation rules described in the "Cancelling a start action" section
above apply. Once the running action has been terminated, the door schedule
record is removed from CDC4 so that no future iterations of the door schedule
can occur.
When deleting a door schedule that is not active, the door schedule is
immediately deleted and no future iterations of the start action can occur.
