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.
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 2-
exchange relay (type 1472) and connect it as shown on the diagram.
Connection of 1281E power supply-timer
instead of 1281 plus 1282E.
By adding 1281E to the schematics on page
203 instead of 1281 plus 1282E, the system
working will modify as follows:
- switching-OFF at the end of the timing only.

Notes
- If monitoring function is required it is necessary to connect the
dashed conductors and:
-Echos series - verify that jumper J5, located on the back of
videointercom, is in the position 2-3;
-Exhito series (possibility of monitoring only the “a” entrance);
- Compact series (possibility of monitoring the “a” and "b" entrances
- connect together terminals 1C and PC on the wall bracket;
- Studio series - connect together terminals 1C, PC and C on the wall
bracket.
- For audio compatibility we do not suggest to connect door stations
MODY series with internal devices ECHOS series.
- 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 one-way systems connect the coaxial cable to the monitor
bracket directly, without using the video distributor.
- For other types of push-button panels see the general catalogue.
