The Farfisa electronic call system allows for the
realisation of intercom, video intercom, digital
and intercom-telephone systems.
The modularity of Farfisa indoor and outdoor
devices allows for system extension to satisfy
the most diverse user’s requirements, from
individual houses to apartment buildings, from
simple intercoms to complete video intercom-
telephone sets.
Selecting the system
The Farfisa electronic call system allows for the
realisation of different types of installation.
• Intercom systems
• Video intercom systems
• Intercom-telephone systems
• Video intercom systems
• Digital systems
(see technical manual n.10)
• Mixed systems (intercom/video intercom/
telephone)
Intercom systems
It is the simplest of the installations. It provides
bidirectional audio communication between
intercoms and external door stations with door-
opening function. The following variants of the
basic installation are possible:
- intercommunicating service. It allows for
communication between different intercoms
of the same apartment or between different
apartments with private conversation to other
users and to external stations.
- private conversation. By adding a board to
each intercom you can restrict the communi-
cation between internal and external user to
the called user. The other users do not hear
the conversation in progress when they lift the
handset.
For the realisation of a basic intercom system
you need 4 common wires + 1 single for each
user.
Video intercom systems
Apart from audio communication and door-
opening function, video intercom systems pro-
vide visual control of the entrance. The typical
characteristics of video intercom systems are:
- Timed operation. The video intercom of the
called user is enabled for about 40 seconds.
The time doubles if the handset is lifted. The
system returns to the stand-by state when the
handset is replaced.
- Private conversation. Video intercom sys-
tems allow for audio communication only for
the called user. The other users do not hear
the conversation in progress when they lift the
handset.
- Intercommunicating service. This service
allows for audio communication between dif-
ferent intercoms or video intercoms of the
same apartment or between different apart-
ments with private conversation to other users
or external stations.
- Control switching ON. The user can enable
the system, switch ON his/her own video inter-
com and monitor the area framed by the cam-
era. Additional wires and activation buttons
are needed in case of multiple entrances.

For the realisation of basic video intercom
systems you need 7 common wires + 1 single
for each user + common coaxial cable or twisted
pair.
Intercom-telephone and video intercom-
telephone systems
It is a variant of traditional intercom and video
intercom systems in which internal stations use
telephones (with monitors for video intercom-
telephone functions) instead of intercoms or
video intercoms. In this case intercom connec-
tions are established over an interface board
that provides telephone and intercom commu-
nication. The interface can be a stand alone
product (art. FT11D) or an interface board to
be installed inside the FT105P or FT208P
electronic PABX (art. ES60 or ES65).
Internal stations can use:
- a standard telephone in which intercom func-
tions are obtained by dialling specific codes
on the keypad
- an intercom-telephone set (art.ST740) or
video intercom-telephone set (art.ST740 +
ST7100) with telephone functions and spe-
cific buttons for the main intercom services.
In intercom-telephone systems the intercom-
municating service can be realized by means
of a PABX that allows also for private conver-
sation.
Intercom-telephone systems need 4 common
wires + 1 single for each user (+ 3 common
wires + common coaxial cable or twisted pair in
case of video intercom-telephone systems) for
connections to the riser. Telephone connec-
tions are made with a telephone pair.
Digital systems
Digital technology allows for reducing installa-
tion time and cost of systems with medium or
large number of users. All calls are sent to a
common data wire, thus eliminating the tradi-
tional single call wire for each user. FN4000
digital systems need 5 common wires for inter-
com systems and 5 common wires + common
coaxial cable (or twisted pair) for video inter-
com systems.
Digital systems provide all traditional functions
of intercom, video intercom and telephone sys-
tems, with additional communication function
with door-keeper service and anti-panic alarms.
For technical details, information on installa-
tion and description of the articles that can be
used for this type of installation refer to Techni-
cal Manual 10 (2005 edition).
Mixed systems (intercom/video intercom/
telephone)
All intercom, video intercom and telephone
systems can be combined according to the
user’s requirements. It should not be forgotten
that there are considerable differences (with
specific products and interfaces) in the
realisation of digital or analogue installations.
Choosing the correct article
When choosing the article and type of instal-
lation, you should consider:
• user’s requirements
• number of users
• installation possibilities
• possible location of articles.
The following options are possible for external
door stations:
• Mody series push-button panels for digital/
analogue intercom, telephone and video in-
tercom systems
• Matrix series stainless steel push-button
panels for digital/analogue intercom, tele-
phone and video intercom systems
• Profilo series push-button panels for ana-
logue intercom, telephone and video inter-
com systems
• Prestige series brass push-button panels
for analogue intercom, telephone and video
intercom systems
• ErreP/R series push-button panels for ana-
logue intercom, telephone and video inter-
com systems
• TM series push-button panels for analogue
intercom and telephone systems
• UP series push-button panels for analogue
intercom and telephone systems with maxi-
mum 2 calls
The following options are possible for internal
stations:
• Studio modular line for intercom, video in-
tercom and telephone systems
• Compact line for intercom and video inter-
com systems
• Project line for intercom systems
• PuntoVirgola line for intercom systems
• Slim (900) line for intercom systems
Slim, PuntoVirgola intercoms and some
models of the Project series are provided with
a mechanical buzzer that is not normally used in
electronic call intercom systems.
