ENGLISH
The distance between the two faces has to be as great as possible (
between 3 and 4 mm
) so that the pressure applied by the door handle
on the brass window is controlled. This also increases the lifetime of the product and allows for smoother closing.
Given that the operation is very tight for correct opening but without excessive power consumption, you must ensure that the lock receives
a
stable 12 v
supply and the specified
amperage
. We thus recommend the use of power supplies and transformers that have sufficient
power for the lock without exceeding 12V.
The electrically-operated lock can be powered either using direct or alternating current. However,
better operation
has been noted
using
alternating current
as the variation in current means that even if there is a slight power failure the lock opens in a short period of time.
For direct current operation we have installed a diode to protect the installation from possible overvoltage. If you plan to use this type of
current and this is not specified in the order, then we recommend that you install a diode.
To ensure that the device receives a voltage of 12V the 850 model can be used with an additional
booster
. This produces an increase
in the initial power supplied, thus guaranteeing its operation even in older buildings where significant power failures may occur. The booster
has to be installed in parallel and as close as possible to the electrical section to ensure the optimal functioning of the system.

INSTALLATION GUIDE:
It is better to install the
ramp shaped accessory
in the
entry to the electrical section to facilitate the entry of the
door handle, thus reducing the force required to close
the door, vibration and noise, whilst also substantially
increasing the door handles lifetime (as the door handle
receives less impact upon closing).
The lock has to be installed in the
centre of the electrical
section
so that the lever head can be freely retracted.
If the door tends to open then the friction reducing nipples
on the side of the level housing will have to be filed down
(in the gap of the electrical section you can see two
nipples on each side; the nipples closest to the opening
direction should be filed - in an outwards direction, never
downwards). In addition a door closer should be installed
to centre both sections automatically.
