Bell Syste~ ~nd~or Multiple ~oor ~P~ r- Systom
The invention relater to a door telephone and bell
eystem with nn array of keys which 1~ provided with at lea~t
one ;~ntif i ~ on sign.
Many designs of bell and ~ultiple door telephone
~ystemo _re known to the Btate of the art ~hich have
' layout of individual functional elements nuch as
n~me platss~ bell key~, door iht~ ~' ~nd ~
rt le Al80 knuwn from DE 83 55 428 Ul for the keys
to be provided with lightn. F~L;' , an aLI _ ~ 18
~ ln DE 81 07 819 Ul in whieh an A; ' -' ~ell is
provldsd wlth a control device whlch ~ake8 it ~ ; h~ e to
di~fer, iAte whether the bell has been rung outside the
house door or outside the ap~ i l door. This i~ _chieved
by the oell havlng two ringing device~ with different
Acoustic signal~ which are integrated in a co~on phase
which al~o cont~ins tho internal control dlodes, while the
oxternAl dloder are - l ~ tn of the apart~nt
bell.
~ he disadvantAge in tho arrAr 'r known to the
state of th~ A-rt i8 that they are only ~uitable for _
relatively R~ll nurber of ap~rt~nts becaure they either

~part~onts with each other they require ve~y high
expenditure on cahling and ~ni~-l part~. Apart from
which, in thl~ case tho c~ble~ mu~t bo indlvldually

The ~ r print~d p4tent docu~ent XP-A-O 03Z g82
descrlbo~ a house nystem for the transmlbnion of

e~senti~lly identically aonutructed, highly integrated
clrcult is provlded ~t oach br~nch ~tntion, where the
desired indivldual function blocka are ~ ~ Led to uaid
circuit. Thefe hlghly int~gr~d clncuit8 are in c ~ 'i~
with each other by ~H~n~ of one ~lngle i ~ ~edium
through nn l.-t _ Ll~ o~ coupllng element~.

Further t~eF~ nQ ny~tem~ ~re known in which the
door tql~rh~n~ statiOn is ~ '~d via a two-wlr~ ; n~rf r -
to th8 t~lorhnn~ sy~te~.
The di~dvantage of the known nL ~ that
~l- t~ 1 c~bling i8 rDqrlre~ between the t~l~r~n~ nnd the
gystem.
The ob~ect of the pressnt lnv~ntlon is to crcate a
door t~ r and bQll nyntem which makss lt EC ~hlc to
~rrango additlonal sxtra functionn ~ Aq the bsll and
thereby suhstAntially avoid add~tional expenditure on
cabling and ~hich make~ a continual updating E ~;hl~ in a
~i~plo vay.
According to the present inventlon, the obj~ct 18
a4hieved ln that olectronically controlled display~ are
provided aB identification slgns and that elsctronically
controlled display~ of a lett~r-box siqn are ~nr ~A to
the ~y~tem.

arQ given in claims 1 to 9.
Whureby it 1B~ for examplc, poRsible that an
eluctronlcally controlled dinplay i~ provided a~ an

connectod vi~ a bun ~ystem to microcontrollers~ The
c 3~n can ~lno be made without a bus syHtem.
LCD diaplays, LED dLsplays, fl rcr displays can
be used for tha electronic diuplay or oven dinplays bssod on

The connection between tho c --'; , stQtlon~ c~n,
for exorple, be ~ade vla a ~ix-cor~d aablo.
In addition, it in pos~i~le for additional ~el ,'
statlons to be _ q t 1 to the sy~tem.
Th~ uy~tem ~ccording to the present invention
distinguishen itself by a high degree of operat~onal
r~ lity and high ~tability ovor lengthy periods of time
~ n consequence of the ~mall number of mechQnical
connoctiny points.
A further su~nt~ntlal adva~t~ge of the syste~
~ '-J to the present invention ari~e~ from the fact thnt
the co~tly manual l~belli~~ of bell nnd l~t~ -bo~ plates

Fur~ e, it is L ~ ;~le for n letter-box sign
provided with an electronic displar to be ndditlonally
~~ ~ L~l to the bell uystem, this in~ Lad via the same
bus.
An adv~ntrJL~us ~ rt of the bell ~y~tem in
nccordanaa with the present invent$on provides ~or
