Working instructions
As the basic system described on page 27, with the
following variations:
- The audio functions and door lock opening are auto-
matically switched to the door station which has made
the call and remain in this state until a call from another
entrance is received.
Notes
- For the connection of name-plate lamps, read notes 6
and 7 of the installation instructions on page 26.
- For wires dimensioning refer to the installation recom-
mendations and table on page 26.
- For other types of push-button panels see pages 22 and
23 or the general catalogue.

In intercoms cut the jumper W1 that connects
terminals 3 and 7 and apply:
- the electronic buzzer SR40 by connecting wires 7
and 9 to the intercom terminals 3 and 9,
- or use the buzzer SR41 by connecting terminals 3
of buzzer and intercom together and by connecting
the call wires to terminal 4 (instead of terminal
as shown in the diagrams).
In all intercoms connect one
of the two terminals of the sin-
gle button unit to terminal 7.
