Model 826 DIGITAL CALL SYSTEM
PERFORMANCE CHARACTERISTICS
TheURMETDOMUSModel826DigitalCallSystemconnectsentrance
panels to apartment stations in large and medium size residential
complexes.
The system can manage two different sets of codes: one for identifying
doorphone and/or video doorphone apartment stations, and one for
identifying special services. For both sets, codes from 1 to 9999 can
be assigned.
Compared to conventional systems, the Digital Call System provides
the following major advantages:
•Riser cable connections are made using only 5wires for standard
doorphone systems, or 7wires plus coaxial cable for video
doorphone systems. This streamlines installation and makes for
significant savings in materials.
•Complex multi-entrance systems can be set up for automatic
switching between entrance panels without the need for additional
switching relays.
•Calls to apartment stations are made by entering acode from 1 to
9999 using the numeric keypad, thus ensuring complete privacy for
residents. However, if residents wish their names to be indicated
on the entrance panel, directory nameplates and/or an electronic
directory with LCD display are available.
•The system can be readily adapted to use conventional Model 725
or Kombi series entrance panels instead of the standard Digital Call
entrance module, simply by installing the appropriate digitizer.
•Special codes can be entered on the entrance module keypad to
activate one or more special services, such as opening the entrance
door, actuating one or more electric locks, opening electric gates,
turning on stair lights, arming asecurity system, and so forth. Each
special code consists of amaximum of four digits from 1 to 9999,
and must always be preceded by a“0”.This “0”has two functions:
it distinguishes special codes from ordinary apartment station call
codes, and prevents the code from being shown on the display while
it is being entered, thus guaranteeing complete security.
• Thesystemfeaturesinherentconversationprivacy:onlythe apartment
station that has received acall from the entrance panel can
communicate with the visitor or hear the call. The conversation can
be maintained for up to 10minutes, or until another call is made.
The system is designed so that electric lockscan be activated
from apartment stations at any time by pressing the switch hook
on conventional buzzer doorphones, or by means of the special
door lockrelease key provided on electronic call tone signaling
doorphones. Alternatively, the system can be programmed so that
only the apartment station which has received acall can activate the
electric lockand thus open the door.
Model 826 DIGITAL CALL SYSTEM
PERFORMANCE CHARACTERISTICS -BASIC CONFIGURATIONS
Ifno other calls are made, this apartment station can release the
door lockonly during the 10-minute maximum call period.
•Ring tone is automatically cut off after 5seconds, thus providing
protection against jammed call buttons, etc.
•Electric locksare actuated through momentary trigger type controls
to ensure that they are not damaged if the door lockrelease button
is jammed, held down for an extended period, etc.
•The system is protected against static and impulse type
electromagnetic interference. Itmeets Level 3requirements as per
IEC 801-2and 801-4.

The installationdiagrams enclosedwith this manualcover the most
frequentlyusedtypes of system.For particularlycomplexsystems
or specialrequirements,contactthe URMETDOMUSlocalagentor
engineeringconsultant.
SYSTEMINSTALLATION
The system must beinstalledinaccordancewith acceptedengineering
practice.Consequently,it is necessary to complywith:
•ApplicableCEIstandards
•The surroundingelectricalenvironment(i.e.,sources of potential
interference).
•System extension.
DEVICELOCATION
Where oneor more devices must belocatedindamp areas or sites
where they couldbeexposedto the weather,it is essentialthat they
beplacedinsealed,watertight containers.
Indoor devices shouldbeinstalledinflush mountingbackboxes
separatedfrom those usedfor telephonesystems,electrical
installations,TVantennas,etc.
DEVICEWIRING
DigitalCall System devices are providedwith removableterminal
blocksto facilitate maintenanceandtroubleshooting.Terminalblocks
are removedbypullingupwards.
The maximum conductor cross-sectionthat canbeaccommodatedin
asingleterminalblockis as follows:
•1 mm2 for strandedcore wire.
•1.5mm2for solidcore wire.
Where conductors with larger cross-sectionsare usedinthe system,
they must besplicedto conductors of appropriate sizefor connection
to terminalblocks.
Wire must bestrippedfor alength of 5to 6mm usinganadjustable
professional-type wire stripper.
Where strandedcore wires are used,it is essentialthat they betwisted
to ensure that disconnectingterminalblockswill not cause wires to
protrude,with the resultingriskof accidentalshort circuits across
adjacentconductors.Ifsolidcore wires are used,devices must be
securedbymeansof screwsor wall plugsso that they cannot move
andbreakconductors.
All conductors connectedto aterminalblockshouldbeboundtogether
with atie wrap,as this makes for aneater appearanceandsturdier
wiring.
NEVERjoinseveralconductors under the same terminalclamp,even
if their cross-sectionsare small. Cap or screwterminalsmust beused
for this purpose.
IMMUNITY TOINTERFERENCE
The second-generationDigitalCall System features ahighlevel
of intrinsicimmunity to staticandimpulse type electromagnetic

2)Branch lines from decoder units to doorphones must not exceed
20 meters in length. Minimum line cross section is 0.5 mm2.
LINE RESISTANCE LIMITS
Conductor cross-section must be such as to guarantee aresistance of
less than 5Ohm on each of the 5conductors (+ 24,-24,D,1,2).

Coax cable Upto 300 m, use standard coax cable
75ohm
Specified distances are those between anycalling device and the
associated decoder unit located farthest from it.
Invideo doorphone systems, coaxial cable is routed in series or using
video splitters at each floor, as in conventional installations.
Each video power supplyunit can supplyup to 15video splitters. If
alarger number is needed, additional power supplyunits Ref. 789/2
must be installed (one for every15video splitters). Onthe last video
doorphone on each riser cable, the coaxial cable must be provided
with a75ohm resistance across terminals V5 and V4.
MAXIMUM NUMBER OFDEVICES
The maximum theoretical number of devices that can be connected in
asystem must under no circumstances exceed 400.
Here, the term device is used to designate anyitem connected to data
line D,including four-port decoders, entrance modules, power supply
units, digitizers and so forth. Doorphones and video doorphones are
not included in the total of 400 devices.
POWER SUPPLYUNITS
The power supplyunit is sized for atypical system configuration,
as it can onlysupplyacertain number of devices. Asindicated in
the installation diagrams, complex systems mayrequire additional
power supplyunits. Insuch cases, each power supplyunit’sterminal +
24Vmust be connected separately:under no circumstances must the
power supplyunits be connected together.
PARALLEL-CONNECTEDEQUIPMENT
Output power from four-port decoder Ref. 826/23is sufficient for two
parallel-connecteddoorphones. Doorphone withsingle-portdecoder Ref.
826/31 can be connected to another Model 1131 or 1132doorphone.
SYSTEMS WITHGUARDDOOR SWITCHBOARDSTATION
Conventional keyless buzzer doorphones Ref. 1130, 1131or 1132
must be used in systems with no guard door switchboard station, as
door lockscan be released bypressing the doorphone switch hook.
Insystems with aguard door switchboard station, single-key
doorphones Ref. 1130/1,1131/1 or 1132/1 should be used.
The keyis used to call the switchboard, while door locksare actuated
bymeans of the switch hookor door lockrelease key.
For complex systems with multiple riser cables, the distance between
anycalling device and the decoder unit located farthest from it on each
riser cable must be considered.
Each individual branch must have aresistance of less than 5Ohm on
each of the 5conductors.
Example:
Branch lines from decoder units to doorphones must not exceed 20
meters in length. Minimum line cross section is 0.5 mm2.

LINE CAPACITANCE LIMITS
For purpose of line capacitance, maximum system extension must not
exceed the following limits:
•Single riser cable systems: 1200 m
•Complex systems: 1500 m
For single riser cable systems, maximum system extension is defined
as the distance between the calling device and the decoder unit
located farthest from it.
For complex systems, maximum system extension is the total length
of all line runs, excluding the branch lines from the decoder units to the
apartment stations.
Example:
GENERAL REQUIREMENTS
The following rules must also beobserved:
1)Donot connect several conductors in parallel in order to reach
the required cross-section (e.g.,multi-core telephone cable).A
single, and preferably stranded-core, conductor of appropriate
cross-section must beused.
2)Incomplex installations, do not leaveopen cable runs (i.e.,with no
decoders connected to the system backbone cable):each cable
run must beconnected to at least one powered device.
Ifthisisnecessarytoaccommodatefutureexpansionorformaintenance
purposes, disconnect the open run from the backbone cable.
3) Never exceed the maximum limit of 400 devices (where the term
device means any item connected to the data line).
4)NEVERconnect power supply units in parallel.
5)Position power supply units in the vicinity of calling devices as
indicated on the installation diagrams.
6) Never exceed the maximum number of devices that can be
connected to asingle power supply unit
7) ALL apartment station equipment in asystem must beof the same
type (i.e.,either all electronic call tone signaling or all conventional
buzzer type).
Mixed configurations cannot beused.
8)Donot connect more than one apartment station for each decoder
(withfour-port decoders 826/23,amaximum of fourapartment stations
can beconnected, i.e.,one - and only one - for each branch).
Ifseveral doorphones or video doorphones must beconnected in
parallel to the same branch, see the applicable URMETDOMUS
installation diagrams.
9)All codes used in asystem must beunique.Never assign two
identical codes in order to maketwo apartment stations ring at the
same time.
SYSTEM MAINTENANCE
Another import aspect to beconsidered when designing asystem
(and one which is often underestimated)is that of maintenance.Thus,
future maintenance needs should beborne in mind at the outset in
order to facilitate workshould aproblem arise.
The following measures are recommended:
1)Where possible, use different colored conductors for each signal,
as indicated in the examples below.
Riser cables:
BLUE=1
GREEN=2
BLACK=-24
WHITE=D
RED=+24
Branch lines:
LIGHTBLUE(BLUE)=1
LIGHTGREEN(GREEN) =2
BLACK=6
ORANGE(RED) =7/CA
PURPLE(WHITE)=9
BROWN=C
Ifallofthecolors suggested for branchlinesarenotavailable, use the
same colors as in the riser cable (indicated in brackets),separating
the conductors with tie wraps and marking them appropriately.
2)Ifwires cannot beidentified byusing different colors, markthem
with tie wraps or other suitable means.
3) Always write down the codes programmed in the decoders on the
labels provided for this purpose on the entrance module.
4)Where doorphones or other devices with single-port decoders
are used (826/14,1204/94),disconnectable junctions should be
installed outside of the apartment so that workcan becarried out
on the riser cable even if the occupant is not at home.This applies
to all devices which must belocated on private premises.
5)Insystems with several riser cables whose wiring is grouped
together at the same point, markeach conductor with the codes for
the riser cable of which it is apart (e.g.,“conductor D,riser cable
1”,“conductor D,riser cable 2”,and so forth).
TYPES OF INSTALLATION
The URMETDOMUSModel 826Digital Call System can beused in
the following types of installation:
•Digital doorphone systems.
•Digital doorphone systems combined with video doorphone
installations.
•Installations with adigital guard door switchboard station serving a
doorphone and/or video doorphone system.
Tofacilitate installation work,always base the system to beset up on one
of the four basic configurations described in the following paragraphs.
Regardlessofthetheoreticalconsiderationsexpressedbelow,itshould
beborne in mind that there is aphysical limit to the maximum number
of devices that can besimultaneously connected in any system.

SYSTEM ACTIVATION
How activation isaccomplishedisfundamental to theinstallation’s
success. If thesystemincludesseveral risercables, eachwith its own
secondaryentrance module,proceedinsuccessivestepsasfollows:
•Separateeachrisercable so thatitisindependent of theothers,
disconnectingtheinputterminalblocksfromthesecondaryentrance
panels.
•Supply power, program, and checktheoperation of eachrisercable
inturn.
•ONLY atthispoint, connecttherisercablesto eachotherand to the
mainentrance panels.
•Checktheoperation of thecompletesystem.
Whetheryouaredealing withasingle risercableinacomplexsystem, or
