Intercom-telephone and video intercom-
telephone systems
Itisavariantof traditional intercom andvideo
intercomsystemsinwhichinternalstationsuse
telephones(withmonitorsforvideointercom-
telephone functions) instead of intercoms or
videointercoms.Inthiscaseintercomconnec-
tions are established over an interface board
thatprovidestelephoneandintercomcommu-
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).
Internalstationscanuse:
-astandardtelephoneinwhichintercomfunc-
tions are obtained by dialling specific codes
onthekeypad
-an intercom-telephone set (art.ST740) or
video intercom-telephone set (art.ST740 +
ST7100) with telephone functions and spe-
cificbuttonsforthemainintercomservices.
In intercom-telephone systems the intercom-
municatingservicecanbe realized bymeans
ofa PABX thatallows also forprivateconver-
sation.
Intercom-telephonesystemsneed4common
wires + 1 single for each user (+ 3 common
wires+commoncoaxialcableortwistedpairin
caseofvideointercom-telephonesystems)for
connections to the riser. Telephone connec-
tionsare made witha telephone pair.
Digital systems
Digitaltechnologyallowsforreducinginstalla-
tion time and cost of systems with medium or
large number of users. All calls are sent to a
commondata wire, thus eliminating the tradi-
tional single call wire for each user. FN4000

Mixed systems (intercom/video intercom/
telephone)
All intercom, video intercom and telephone
systems can be combined according to the
user’srequirements.Itshouldnotbeforgotten
that there are considerable differences (with
specific products and interfaces) in the
realisationofdigitaloranalogueinstallations.
