Lock cylinder requirements
The door lock drive mounted direct-
ly on the cylinder lock (F) of the door;
when the appropriate key is inserted,
the drive causes the cylinder to move.
Accordingly, the cylinder lock must be
dimensioned so that it juts out on the
inside of the door by 8 – 15 mm more
than the handle fitting.
8 - 15 mm
Determine the dimensions of the re-
quired lock cylinder.
G H
When selecting the lock cylinder, the
inner dimension (G) and outer dimensi-
on (H) of the cylinder are significant.
It is always measured from the outsides
of the lock cylinder including door fit-
ting to the fixing screw (I).
Once you have determined the inside
and outside dimensions of your lock
cylinder, check whether the inside di-
mension overlaps by 8 – 15 mm for the
installation of the door lock drive.
If this is not the case, add 8 – 15 mm to
the inside dimension (ideal 10 mm) to
find the appropriate standard size.

Example:
You measure an outside dimension
of 40 mm and an inside dimension of
40 mm. Therefore, the cylinder is a
40/40 cylinder. In order to use the lock
actuator, you therefore need the next
standard size, a 40/50 cylinder. The
cylinder will then protrude inside by
10 mm.
If necessary, please replace your
lock cylinder by a new one if it
does not fulfil the installation
requirements. Make sure that you
only use locking cylinders with
emergency and danger functions
in which the key is turned syn-
chronously on the inside. This is
necessary so that the position can
be transmitted correctly.
