Requirements on the door and the used lock cylinder

Read this section entirely before starting to mount the device!
Door requirements:
The door lock drive can only be used on doors with locks and bolts that move easily and
do not jam.
Please note!
Doors with locks that can only be operated by pushing, pulling, lifting, lowering
or twisting the door are not suitable for operation with the door lock drive!
• Note, especially with wooden doors, that weather can cause the door to warp,
which can in turn make the door unsuitable for locking and unlocking operation with
the door lock drive at times. The door lock drive cannot handle the forces that are
required by a warped door on the door latch.
• Make sure that the door can be locked and unlocked smoothly and easily under all
climatic conditions before implementing the drive. This can be tested by locking and
unlocking the door lock with the key and without using the door handle. Set the door
hinges and/or the striking plate in the door frame so that locking and unlocking is
smooth and easy with the key as described previously.
• In order to use the door opening function of the KeyMatic system, the door seals
must be intact and designed so that the door will open on its own after completely
unlatching the lock because of the expansion of the door seal.
Lock cylinder requirements:
The door lock drive is mounted directly on the cylinder lock (N) and moves the cylinder
with the respective key inserted. Accordingly, the cylinder lock must be dimensioned so
that it juts out on the inside of the door (K) by 8 -15 mm more than the handle fitting.
Determine the dimensions of the required lock cylinder using fig. 3. When selecting the
lock cylinder, the dimensions "inside" (inside cylinder dimension) and "outside" (outside
