Notes
- To have the control switch ON for the 2 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 connection
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:
- Carrying out a call from the entrance only audio,
the corresponding monitor turns itself ON without
images.
-The audio-video operations and the door lock
release are automatically switched at the time of
the call or with the control switch ON.
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 deactivation
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.
