Notes
- Connect the video intercom terminal 4 (wire
shown with dotted line) if the control switch on
from the secondary door station is required.
- For the connection of name plate lamps read
notes 6, 7 and 8 of the installation instructions
on page 91.
- For wires dimensioning and video connec-
tion refer to the installation instructions and
Si 37MO/1
Connection of two door locks, of which
the secondary is always activable, in a
system with multiple entrance
For this option it is necessary to install a
diode (100V-1A; type 1N4007) between
terminals 7 (cathode) and 7a (anode) of
every secondary exchanger.

button panel.
table on pages 91÷93.
- To use the Matrix series push-button pan-
els, see the application diagram and notes
on page 115, 117 or 119.
Working instructions
It is similar to the basic system described on
page 94, but with the following variations:
- The audio-video operations and the door
lock release are automatically switched at
the time of the call or with the control switch
ON.
- The services towards the secondary video
entrances are independent among them-
selves and therefore they can function at the
same time.
Control switching ON deactivation
To activate the control switching ON from the
videointercoms only when the system is in standby,
it is necessary to install a relay (type 1471 or 1472)
and connect it as shown on the diagram.

The main entrance push-button panel
must have separate common terminals.
One common terminal for each secondary
door station. Buttons of the Mody series can
be divided into 2-button groups.
