Notes
- To have the control switch ON for the 3 video
entrances it is necessary to make the dashed
line connections and use WB5160, WB5660,
WB2160, WB1260 wall brackets. The wall
brackets are configurated to work without the
audio privacy, to restore it the jumper J1
must be moved (see pages 73, 75, 77, 79
and 80).
- 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
table on pages 91÷93.
- For one-way systems connect the coaxial
cable to the monitor bracket directly, without
using the DV video distributor.
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.
Si 33MO/1
Use expandable fixing brackets
WB5160, WB5660, WB1260,
WB2160.
Floor-call
This working diagram allows for differentiat-
ing the floor-call from the call from the push-
button panel.
Control switching ON deacti-
vation
To activate the control switching
ON from the videointercoms only
when the system is in standby, it is
necessary to install a 2-exchange
relay (type 1472) and connect it
as shown on the diagram.
