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
- You can also use Prestige and TM push-button panels. For the latter series you must request the version
with separate common terminals.
- For the connection of name-plate lamps, read notes 6, 7 and 8 of the installation instructions on page
26.
- For wires dimensioning refer to the installation recommendations and table on page 26.
- Telephones can be used instead of intercoms (see “telecommunication” section).
- For other types of push-button panels see pages 22 and 23 or the general catalogue.
Application of Matrix push-
button panel
The button common terminal of
every module CANNOT be
separated. For the composition of
the push-button panel at the main
entrance, carefully select the button
modules in order to obtain the
necessary number of buttons for
every common terminal.
Use the power supply
with electronic
buzzer PRS240
instead of PRS220
