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
- Do not forget to connect terminals C of the additional buttons and install the SR41 electronic buzzer in each intercom.
- If only 2 intercommunicating intercoms are requested, even Compact series can be used (see page 76).
- When using intercom PT526E you must connect the common terminal of the additional buttons to terminal 7.
- For the connection of name-plate lamps, read notes 6 and 7 of the installation instructions on page 35.
- For wires dimensioning refer to installation instructions and table on page 35.
- For other types of push-button panels see pages 30 and 31 or the general catalogue.
