Description of basic functions
4.4
Temporary unlocking (KZF)
4.4.1
Temporary unlocking releases the emergency door protection for a limited time. During this time, access through
the door is possible without triggering an alarm. It is activated with the built-in key switch or an external actuator
connected to the Temporary Unlocking input.
Cancellation of temporary unlocking
4.4.2
When temporary unlocking is active, the door locks prematurely when it is closed before the temporary unlock-
ing time has expired. This prevents unauthorized access through the door after an authorized person has gone
through.
Retriggering on temporary unlocking
4.4.3
If the temporary unlocking function is triggered again while the function is still active, the temporary unlocking
period starts again.
Pre-alarm
4.4.4
If the door is passed through after the temporary unlocking time has expired, an audible signal is issued to warn
the user that the temporary unlocking time has expired. If the door is closed while a pre-alarm is active, the door
is locked again automatically and the pre-alarm is reset.
Door alarm
4.4.5
If the pre-alarm time is exceeded, the door alarm is triggered. This must then be reset with the built-in key switch
or with a new temporary unlocking command. If the door is closed while the door alarm is active, it locks and can
be unlocked again only after the alarm has been reset (except when the emergency button is pressed or emer-
gency unlocking is triggered). The door alarm is also triggered when the door is opened forcefully.
Unlocked
4.4.6
The power supply to the locking element is permanently interrupted. The door can be passed through without
triggering an alarm.
Locked
4.4.7
The locking element is energized through the door control unit. The emergency door protection is active and
unauthorized people can open the door only by pressing the emergency button, which triggers an alarm.
Emergency unlocking
4.4.8
The TZ320 can be unlocked in an emergency by the fire detection, burglar alarm or hazard alert system. This is a
non-safety-relevant interruption of the power supply to the locking element.
Direct unlocking (according to EltVTR)
4.4.9
Safety-relevant interruption of the power supply to the electrical lock through an NC contact when the emer-
gency button is pressed.
