Unlocking function
Unlocking from the inside
The lock can be unlocked from the inside at any time using the panic function.
Day mode (switching function, panic B)
When Day mode is activated, the flip latches are blocked and the bolt is retracted to 5 mm. The door is not
considered to be locked, rather just held closed.
Day function (suffix TF)
When the Day function is activated, the flip latches are switched to a soft action setting and work in the
same way as a roller latch. The flip latches are not blocked. Switching in opened door status, 1 x key turn in
closing direction.
The lock is mechanically self locking and the door is,
therefore, always locked when in a closed state. The lock is
unlocked by mechanical actuation.
Functional locking principle
When the door is closed, the extended flip latches
(Fig. 5 –
2
) are pressed inwards onto the strike plate. If the
flip latches are pressed in, the trip latch can also be (–
pressed in. When the door is completely closed, the flip
latches slide into the latch opening in the strike plate and
are then extended again. The trip latch remains pressed in.
When the flip latches are extended and the trip latch is
pressed in at the same time, then the bolts (–
released and extended by a spring mechanism.
The locking process is concluded.
