Working instructions
It is similar to the basic system described on
page 94, but with the following variations:
- from the intercom the user has about 40 sec-
onds to answer by lifting the handset and there-
fore can speak for an unlimited time with video
privacy towards the other users. By replacing the
handset the system shuts itself OFF.
Notes
- If the control switching ON is necessary, con-
nect terminal 4 of the timer (dashed wire).
- If no private conversation feature is required,
all intercoms in the “Intercom” chapter can be
used.
- 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.
In video intercoms the private conversation feature
is permitted by the jumper J1 (position 2-3)
located on the fixing bracket. In intercoms you must:
- insert the private conversation module art. SM50;
- to cut the jumper W1 that links the terminals 3 and
7.
- move the connection of the buzzer from terminal
3 to 7.
- make the connection between terminal 7 of the
intercom and the - (minus) of the privacy module.
Cut the resistance R1 in all of the privacy modules.

Application of MD100 and MD200 modules
When using MD100 and MD200 amplified external door stations, it is recommended to
combine the diagram on page 98 with diagram on page 101 by aligning it to the riser.
For wires with alternate power supply refer to directions on page 91.
