The following pages show the installation diagrams that are most commonly used in videointercom 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 installation diagrams with 1 or more external door stations contained in this technical manual are shown with only one video intercom for
every user. Installation can be customised by combining the applications on pages 126 to 148 with the basic diagrams on pages 99 to 123. For
more information see page 124 and 125.
The installation diagrams shown from page 99 to 119 and on page 123 can also be used for one-way installations by connecting only one
video intercom, using only one call wire and not using the floor video distributor (the coaxial cable is directly connected to the video intercom
bracket).
The "Telephony" chapter contains only some video intercom telephone installation diagrams (page 176 to 187) with application diagrams (see
pages 188 to 191); many of diagrams contained in the "Video Intercom" chapter can be used following the instructions on page 170. Mixed video
intercom/video intercom telephone systems with video signal connection by means of twisted pair are not possible.
