The following pages show the installation diagrams that are most commonly used in intercom systems. Upon request ACI Farfisa can supply
installation diagrams for configurations that are not included in this manual.
Systems with 1 or more main entrances
Systems with 1 or more main entrances and secondary door stations
Systems with private conversation
Intercommunicating systems without external door station
Intercommunicating systems with 1 or more main entrances
Intercommunicating systems with 1 or more main entrances and secondary door stations
Systems with floor-call
Systems with intercommunicating service between intercoms in individual flats
For a clearer understanding of the diagrams, the sequence of terminals in each individual article has not been followed. Only the
terminal code (letter and/or number) is valid, not the graphic sequence.
Terminals with the same letter or number have the same functions.
The items may have more terminals than the ones shown in the installation diagrams. The excess terminals must not be connected.
- The intercommunicating installation diagrams connected to 1 or more door stations allow for the use of 5 intercommunicating intercoms
(see diagrams from page 47 to 61). If a different number is required, the installation diagrams on pages 62÷70 should be looked at, paying
attention to the type of installation (single or common call from door station). The installation diagram to use (2, 3, 4, 6 or 7 intercoms) should
be also copied and placed over the 5-intercom basic diagram.
Example: copying the installation diagram of 4 intercommunicating intercoms on page 66 and placing it to the installation diagram on page
53 (Si 121L/5M), aligning the 6 cables at the riser, will produce a system of 4 intercommunicating intercoms connected to 2 external door
stations with common call and electronic ringing for internal calls.
- The “telecommunication” section contains only some intercom-telephone (pages 173÷175); many of the installation diagrams contained
in the intercom sections can be however used, following the indications on page 170.
