The main entrance push-button panels must
have separate common terminals. One common
terminal for each secondary door station. Buttons of
the Mody series can be divided into 2-button groups.
The common terminals of push-buttons Profilo and
Matrix series can be separated only module by

Working instructions.
As the basic system described on page 218, with the following variations:
- The audio-video functions and door lock opening are automatically switched to the door
station which has made the call (or control switching ON) 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 audio compatibility we do not suggest to connect door stations MODY series with
internal devices ECHOS series.
- If the control switching ON is necessary, connect terminal 4 of the timer (dashed wire).
- For the connection of name plate lamps read notes 6, 7 and 8 of the installation
instructions on page 146.
- For wires dimensioning and video connection refer to the installation instructions and
table on pages 146÷148.
- For other types of push-button panels see the general catalogue.
Connection of 1281E power supply-timer in-
stead of 1281 plus 1282E.
By adding 1281E to the schematics on page 217
instead of 1281 plus 1282E, the system working will
modify as follows:
- switching-OFF at the end of the timing only.

Control switching ON deactivation
To deactivate the monitoring function
during the conversation and to keep it
only when the system is in standby, it is
necessary to install a relay (type 1471 or
1472) and connect it as shown on the
diagram.

Connection of two door locks, of which the
secondary is always activable, in a system with
multiple entrance
For this option it is necessary to
install a diode (100V-1A; type
1N4007) between terminals 7
(cathode) and 7a (anode) of every
secondary exchanger. The diode
allows to activate also the door
look of your own entrance when the
door look of the main entrance is activated. On the
contrary when the door lock of your own entrance is
activated the door look of the main entrance is not
activated.
