The following pages show the installation diagrams most often used in DUO digital intercom/video intercom systems.Upon request ACI Farfisa supplies installation diagrams for the configurations not present in this manual.

Videointercom systems with 1 or more main entrances Videointercom systems with 1 or more main entrances and secondary entrances Combination intercom-video intercom systemsSystems with floor call Systems with intercommunicating service between video intercoms and intercoms in single or apartments

For a clearer understanding of the diagrams, the sequence of terminals in each individual article has not been followed. Only the terminal codeis valid (letter and/or number), not the graphic sequence.Terminals with the same letter or number have the same functions.

The items may have more terminals than the ones in the installation diagrams. The excess terminals must not be used.

The installation diagrams for 1 or more door stations illustrated in this technical manual have been represented with only one intercom or videointercom for each user. However, it is possible to “personalise” the installation by matching properly the applications on page 116 to the basediagrams of pages 93÷115.

Graphic symbols

For a better comprehension of the installation diagrams we have made a list of the graphic symbols most often used.

INSTALLATION DIAGRAMS

Optional wire (normally for connectionof floor buttons and door lock button)

Division lines (for conveniencepurposes only the first and last userare illustrated in multi-way installations.Theoretically, all articles that arenecessary for the installation areincluded between the two division lines)

Digital push-button panel

Conventional push-buttonpanel with digital encoder

Intercoms

Power supplies, transformers,exchangers and actuators

Videointercoms

Floor distributors

J.. mobile jumpers to adjust line im-pedance (available in floor distribu-tors and video amplifiers) and pro-gramme external door stations, ex-changers and actuators. Their correctposition allows for the correct opera-tion of the installation.

SW.. microswitches in exchangers.digital encoders and push-buttonmodules. They must be positioned asindicated in the installation diagramsand installation instructions.

Push-button

Electric door lock

Switchboard. We recommend toinstall all articles in this frame in thesame switchboard.

Note to two-family installations- The user code of external door stations and

videointercoms is 100 by default; for this reason, thesecond videointercom must be programmed with code101 (see automatic programming of videointercomson pages 16 and 23).

- In videointercom 1 move jumper J11 (EH9262..) or J1(KM8262..) from position 3-4 to 1-2 (open line).
