Notes
- For the connection of name plate lamps read notes 6, 7 and 8 of the installation
instructions on page 111.
- Connect the video intercom terminal 4 (wire shown with dotted line) if the control switch
on from the secondary door station is required.
- To install a colour system, the ST7100CW video intercoms and the MD41C, MA42C,
MA43C, PL40PC, PL41PC or PL42PC camera must be used.
- For wires dimensioning and video connection refer to the installation instructions and
table on pages 111 and 114.
- Telephones can be used instead of intercoms (see “telecommunication” section).
- For other types of push-button panels see the general catalogue.
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.
Control switching ON deactivation
To activate the control switching ON from the inter-
coms only when the system is in standby, it is neces-
sary 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.
Common terminals of Matrix and Profilo push but-
tons cannot be separated.
