The Farfisa electronic call system with reduced
wires technology allows for the realisation of
intercom, video intercom and intercommuni-
cating 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 videointercoms.
Selecting the system
The first choice to be made is the preferred
type of system.
• Analog system with reduced number of
conductors (1+1 intercoms: 1 common
wire +1 wire for each user; 4+1 videointer-
coms: 4 common wires +1 wire for each
user).
• traditional analog system (4+1 intercoms:
4 common wires +1 wire for each user; 7+1
videointercoms: 7 common wires +1 wire
for each user + coaxial cable).
The Farfisa electronic call system allows for the
realisation of different types of installation.
•
Intercom systems with 1 or more main
entrances and with or without secondary
entrances
•
Videointercom systems with 1 or more
main entrances and with or without second-
ary entrances
•
Intercommunicating systems
•
Mixed systems (intercoms/videointer-
coms/intercommunicating systems)
GENERAL CHARACTERISTICS
•
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.
•
Videointercom 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 100 seconds.
Picking-up the handset the enabling time will
be doubled; hanging up the handset the sys-
tem switches back to the stand-by mode.
Systems which are using the power supply-
timer art.1181E and 1281E switch back to the
stand-by mode only when the enabling time
expires.
- 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.
•
Mixed systems (intercoms/videointer-
coms/intercommunicating systems)
All intercom and video intercom systems can
be combined according to the user’s require-
ments.
Selecting the articles
When choosing the article and type of installa-
tion, you should consider:
•
user’s requirements
•
number of users
•
installation possibilities
•
possible location of articles
The following options are possible for external
door stations and internal stations:
• External door stations:
- Agorà series
- Profilo series
- Matrix series (steel push-button panels)
- Mody series
- UP series
• Internal stations:
- Echos series
- Exhito series
- Compact series
- Studio series
- Project series
Optional wire (usually control switch-
ing ON, door release button or inter-
communicating calls)
Dashed line (for schematic purposes
the first and last monitors are shown in
the multi-family systems. Required
additional monitors can be inserted in
such dashed line to complete the in-
stallation).
