Working instructions.
As the basic system described on page 36, with the following variations:
- The audio functions and door lock opening are automatically 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, 7 and 8 of the installation instructions on page 35.
- For wires dimensioning refer to the installation recommendations and table on page 35.
- Telephones can be used instead of intercoms (see “telecommunication” section).
- For other types of push-button panels see pages 30 and 31 or the general catalogue.
