Installation of the Kaba Mauer guiding tube:
The key hole in the door of the secure storage unit has to be dimensioned between 11 and 13 mm (following DIN 2768-
mH), considering the outer diameter of the tube shown in sketch 3, the secured area given in sketch 4 and the security
requirements of the secure storage unit. According to sketch 4, all areas outside the given zone have to be protected by
the armoring of the secure storage unit.
During the installation and adjustment make sure that the key guiding tube gets properly put onto the two round projections
on the lock case as well as to the round groove of the key hole cover. Please take care that after installation the key
guiding tube is in a 90° angle to the lock and the escutcheon (see sketch 5: section of mounting situation).
Length (L) of the key guiding tube in mm: L = X + 2,4 [+0/-0,5] mm
Length (L) of the key guiding tube in inches: L = X + 0,095 [+0/-0,019] inches
(see sketch 5).

If you’re not using the Kaba Mauer escutcheon and key guiding tube make sure that the inner diameter of the alternative
key guide has the same dimensions as the Kaba Mauer tube following DIN 2768-mH. The dimensions of the key guide
have to follow the security requirements of the secure storage unit and considering the security area given in sketch 4. All
areas outside the given zone have to be protected by the armoring of the secure storage unit. After installation, the key
guide has to be well fixed and it has to be in a 90° angle to the lock and –if used - the escutcheon. After the installation
make sure that the key can be easily inserted into the lock and turned with minimal force and without binding.
When using the optionally available bolt switch please make sure that the area shown in sketch 6 is kept clear to prevent
the cables or the switch from being damaged. The cables must not be buckled in the area of the heat shrinking tubes. The
cables have to be installed such that they can’t be damaged by moving parts (e.g. from bolt work) or sharp edges. For
further details regarding the specification of the bolt switch cables refer to sketch 7.
Install the bolt switch according to sketch 8 and secure it with the supplied Quicklock ring according to sketch 9.
It is highly recommended to use a dedicated mounting tool for the Quicklock ring. This tool can be supplied by Kaba
Mauer.
After the installation of the bolt switch test the mechanical and electronic function of the bolt switch. Attach the bolt switch
cables needed for your application to an electrical test device and open and close the lock several times.
