VERTICAL CONFIGURATION
The module holder supports (KSM 70/1 - KSM 70/2 and KSM 70/3 KSM70/4) are provided with a preassembled
lower plastic head. Both the supports and the heads have an anodised grey aluminium colour (e.g. AN6025/
L).
To complete the panel, simply insert the module(s) in the specifi c grooves, as shown in the drawing.
When making a panel with several button modules, before inserting the second module, remember to loosen
the two screws on the side of the "Button Common" of the lower module. Arrange the plastic spacer included
with the module support, insert the next module making sure that the 2 forked tabs are correctly inserted
under the two screws of the previously inserted module (DO NOT TIGHTEN THE SCREWS). Proceed following the
steps shown in the free fi gures on the embedding box (and the fi gures below).
Complete the panel preparation by inserting the upper head and tightening the two head closing screws
included.
For panels formed by several modules, complete assembly by tightening the two screws of the button
module.
The panel is now ready and correctly assembled.
Remember to fold the two button common forks by 90° on the last module on the bottom (the one in
contact with the lower head) as shown in the fi gures to avoid interference.

When assembling button modules with other than 4 buttons, connect two wires between the upper and the
lower module for the "button common" (follow the specifi c instructions shown in manuals and diagrams
for special systems).
HORIZONTAL CONFIGURATION
The panels may also be assembled horizontally (up to 3 rows). Coupling profi les are included with the module
supports for this application. Insert the profi les in the two external grooves of the two module supports
arranged side by side. Perform this operation before fi xing the upper heads. The profi le accessory allows to
perfectly align the panels without the use of frames (as shown in the fi gures on the packing and in the fi gures
on page 12).
button common to the left button common in the same row (unless otherwise specifi ed in specifi c system
instructions).
BUTTON COMMON CONNECTION (in standard audio-video systems)
In order to avoid in-line jumpers, all button modules (including the 1-button GVM70/1 AN6082/L video
doorphone module) have two forks on the lower side in correspondence of the two "button common"
contacts.
To connect the button common between module and module, simply loosen the screw of the fi rst button on
the lower module, insert the fork and close the screw. The operation is described in the vertical assembly
paragraph.
If multiple row panel versions are used, use one connection wire between the two button commons of the
adjacent rows. For video versions on multiple rows with only one module in each row (horizontal confi guration),
connect the button module common with a wire to the CP terminal of the video
module (GVM 70/1), since the button common screw is not accessible.
You will still need to jump the right button common to the left button common
within the same row.
PANEL BACKLIGHT CONNECTION
The name tags lighting is obtained by connecting the power wires identifi ed by
terminals ~ and ~ on the audio/video or 0 ~ on the audio group unit to the two
terminals identifi ed by letter "L" on the printed circuited positioned behind the
module. (Refer to the button module instructions for details).
Proceed in the same manner for each button module (1, 2, 3 or 4 buttons).
See fi gure.
WALL INSTALLATION
After assembling the panel, anchor the lower heads to the embedding boxes
using the screws included with the "module supports". Proceed by connecting
the system wires as described in the following paragraph and then, once
correctly aligned, fasten the upper head in the same manner. Important: In
horizontal confi gurations, remember to fi x all the upper and lower screws:
otherwise the panel may not adhere perfectly to the wall and water infi ltration
may occur.
