The following pages show the installation diagrams that are most commonly used in intercom, video intercom and telephone 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-video 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 55 to 71). If a different number is required, the installation diagrams on pages 74÷80 should be looked at, paying attention
to the type of installation (single electronic call, common electronic or alternate current call from door station). The installation diagram to use (2,
3, 4, 6 or 7 intercoms) should be also photocopied and placed over the 5-intercom basic diagram.
Example: photocopying the installation diagram of 4 intercommunicating intercoms on page 78 and placing it to the installation diagram on page
65 (Si 221L/5S), 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 and external calls.
- The “telecommunication” section contains only some intercom-telephone (pages 215 and 216) and video intercom-telephone (pages
217÷227) installation diagrams, with application diagrams (see pages 228÷230); many of the installation diagrams contained in the intercom and
video intercom sections can be however used, following the indications on pages 212 and 213.
