Working instructions.
As the basic system described on page 27, 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.
- Services to secondary door stations are independent and can be operated at the
same time.
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 recommendations and table on page
26.
- For other types of push-button panels see pages 22 and 23 or the general catalogue.
