VIDEOINTERCOMS
Extension of ONE-WAY system
To realise a one-way system with several monitors and/or
intercoms in parallel, with or without intercommunicating
service, you must proceed as follows:
- make a photocopy of the additional diagram desired, select-
ing it among those of pages 222, 223, 224, 226 and 227;
- place the diagram on the basic diagram so as to cover the
existing video intercom and line up the wires of the two
diagrams;
- if specified in the additional diagram, connect the wires I and
C (common terminal of additional buttons) to terminals IV and
7 of art. 1282E;
- to obtain the intercommunicating service, make the connec-
tions which have been drawn with a dashed line, install the
1443E module inside timer 1282E and move the jumper J1
of the videointercom bracket from position 2-3 to 1-2.
Example (see page 219): by making a photocopy of the
additional diagram of page 224 (2 video intercoms and 1
intercom in parallel with or without intercommunicating serv-
ice), placing it on the installation diagram of page 197 (Si
42MO/1), lining it up to the wires of the first video intercom and
eliminating the second video intercom and the video distribu-
tor, it is possible to obtain a one-way system with 2 video
intercoms and 1 intercom in parallel connected to 2 external
video stations.

Extension in one apartment of a MULTI-WAY system
To realise a multi-way system with several video intercoms and/or intercoms in
parallel in one apartment with or without intercommunicating service, you
must proceed as follows:
- make a photocopy of the additional diagram desired, selecting it among those
of pages 223, 225, 228 and 229;
- place the diagram on the basic diagram so as to cover the existing video
intercom and line up the wires of the two diagrams;
- to obtain the intercommunicating service, make the connections which have
been drawn with a dashed line and move the jumper J1 of the videointercom
bracket from position 2-3 to 1-2.
Example: by making a photocopy of the additional diagram of page 224 (2
videointercoms and 1 intercom in parallel with or without intercommunicating
service), placing it on the installation diagram of page 197 (Si 42MO/1), lining it
up to the wires of the first video intercom, it is possible to obtain a multi-way
system with 2 video intercoms and 1 intercom in parallel in one apartment and
intercommunicating connected to 2 external video stations.
Extension of a MULTI-WAY system in several apartments
To realise a multi-way system with several video intercoms and/or intercoms in
parallel in 2 or more apartments with or without intercommunicating service,
you must repeat the operations described in the preceding section several times.
