5. Installation and activation of the monitor
Execution of electrical installation
Detailed recommendations regarding the electrical installation of the video door entry sys-
tem can be found in the operating instructions of the CD-2502 or CD-3100 digital door pho-
nes.
The installation should be done using video splitters. You need one splitter for four mo-
nitors.Thesplittercanactasacentralpowersupply,providedthatitispoweredfromthe
15VDC/4A power supply. With this connection the distance between the splitter and the mo-
nitorshouldnotexceed30m,accordingtothetableinFigure4.Themonitorcanalsobepo-
weredfromalocalpowersupply13,5V/1,2A.Thisisrecommendedifthedistancebetween
the external panel and the monitor exceeds 30m. The video signal should still be fed from
the CVR-2 splitter. For video installations it is recommended to use UTP cat.5.5.
Monitor installation
Monitorshouldbemountedinsidethebuildinginaplaceeasilyaccessibletotheresidents,
ataheightofatleast1,5minsuchawaythatitdoesnotposeathreattothemandisnot
exposed to accidental hit.
Do not install the monitor in front of a window or strong light source as this may make it dif-
culttoobservetheimageonthemonitorscreen.Itisnotrecommendedtoinstallmonitors
innarrowcorridorsorpassageways,asthismaycausesounddistortion.
Themonitorshouldbemountedatleast1,5mfromsourcesofstrongelectromagneticinter-
ference–transformerpowersupplies,magnets,metalsewerandgaspipes,asthismaycau-
seimagedistortion.Itisrecommendedtoplaceaush-mountedelectricalboxwithaxing
socket or an electric switch in the place provided for the monitor installation. Connect the
monitor connection cables in a box. Attach the monitor mounting bracket to the box so that
the holders with the holes will be directed up. Attach the mounting plugs to the cables (Fi-
gure5and6).Inserttheplugsintotheappropriatesockets,remembertoputthepowerplug
at the end.
Programthemonitornumber(seesection6„Programmingthenumber”).
Finallyattachthemonitortothemountingbracketandlightlypullitdown,overcominga
slight resistance.

Connecting an additional camera or COMMAX panel
To the monitor can be connected an additional camera or COMMAX video door entry pa-
nel. The CN CAM2 connector is used for this purpose.
Inthecaseofanexternalpanel,connectthewiresinaccordancewiththedescriptionofthe
plug.
Thepanelallowsyoutocallthemonitor,conductaconversation,pressingtheelectricstri-
ke’sbuttoninthemonitorwillactivatetherelayinthepanel,whichcancontroltheelectric
strike. As an additional camera a standard camera with a COMPOSITE VIDEO output can
beused.Itcanbeadisccamera,adomecamera,acameraintheformofaviewnderetc.
AnadditionalcameracanbedirectlyconnectedtotheCN_CAM2plugforVC(+12V),GND
(ground) and C2 (video) terminals.
Someoorpanelsrequire5Vinrestconditionforproperoperation.
TheJP2jumperallowsyoutosetarestingvoltageof1,5Vor5Vonthemonitor’spower
line.
Connecting the doorbell
Themonitorcanreplacethestandarddoorbell(DING-DONGgongsignal).Forthispurpo-
se,astandardbellswitch(NO)shouldbeconnectedtotheterminalsoftheCN_BELLplug.
It should be noted that the switch terminals were not connected to elements of any other in-
stallation,inparticularto230Vmains.
Connecting an additional device
AlongpressoftheCONTROLbuttonactivateforapprox.1secondtheinternalrelay,which
shortstheNOterminalsintheCN_BPplug.Thesecontactscanbeused,forexample,tocon-
trol the drive of the entrance gate or automatic barrier (Figure
6. Programming the number and activating the monitor
Bydefaulttestnumber63isprogrammedineachmonitor.Ineachmonitormustbepro-
grammed target number (including 63).
In the monitor you can set numbers in the range 1...254. It is not possible to program other
numbers.ToprogramthenumbertheLOCKandCONVERSATIONbuttonsareused,as
wellasthePROGbuttonlocatedonthesideofthemonitor.Thenumberofhundreds,tens
and units of the programmed number are programmed sequentially.
Description of buttons:
PROG–enteringtheprogrammingmode(Figure1).
CONVERSATION – entering the programmed value.
LOCK–conrmationofthevalue,transitiontothenextprogrammingstage.

• UTP+TERMINATOR – set the jumper in this position if the video signal is sent symme-
trically with the UTP cable and the monitor is located at the end of the video bus or is the
only line load. In this position the line is loaded with a 100R resistor.
Adjusting the monitor
The regulations available to the user are described in point 3 of this instruction.
In special cases you can adjust the audio signal using the following potentiometers available
on the back of the monitor:
• BAL1–correctionofthelevel(volume)ofthesignalcomingfromtheexternalpanel
• MIC1 – correction of the level (volume) of the signal coming out to the external panel
• BAL2–correctionofthelevel(volume)ofthesignalcomingfromtheoorpanel
• MIC2–correctionofthelevel(volume)ofthesignalcomingouttotheoorpanel
7. Operation of the „installation procedure” (requires activation in the CD-
2502/3100 system)
The procedure makes it easier to activate the door entry system. After starting the installa-
tion procedure you can set in the monitor the number of rings and the tone and volume of
the call (these are individual settings for each apartment number). Then the electronic mo-
dule automatically establishes connection with the handset or monitor in which the procedu-
rewasactivated,givingtheinstallertheabilitytocheckthedevice.
Turn on the preview from the CD door phone camera (one touch of the PREVIEW key) and
press the CONVERSATION button four times. The LED1 and LED2 light up at the same
time.
• Press the LOCK button once. The electronic module will start looking for the monitor
number in which the installation procedure was activated.
• Afterndingthemonitorthemonitornumberwillbedemonstrateusingtheacousticsi-
gnals(threedigitscorrespondingtothenumberofhundreds,tensandunits,similartopo-
int6).Alongerbreakmeansmovingtothenextnumber,alongersoundmeansthatthe
numberiszero.
• Select the call tone by pressing the LOCK button sequentially.
• Set the call volume in the door entry system using the CONVERSATION button (do not
confusewiththevolumesettingdirectlyinthemonitor,seepoint3).Therearethreevo-
lumelevels(loud,moderate,quiet)andaincreasingsignal(threeshortbeeps).
• Theselectedsettingsmustbeconrmedbylong-pressingtheCONVERSATIONbutton.
• After a moment the electronic module will call the monitor in which the installation pro-
cedure was activated. Press the CONVERSATION button to get a connection. The instal-

lercanchecktheoperationofthevideo,soundandelectricstrike.
• End the conversation.
8. Doorbell function
In the monitor there is a generator which can function as a door bell.
The generator is activated with a bell button connected to appropriate terminals in the mo-
nitor. Pressing the bell button causes generating gong sound. If bell button is pressed during
monitorcallingthencallsignalwillbereplacedforamomentbygongsound,andthenswit-
ched on again.
All signals are automatically turned down during the conversation.
Note!
Bellterminals(BELL,GND)shouldnotbeconnectedtoanyotherelectricalsystems,espe-
cially 230V mains.
9. Maintenance
Inthecaseofcontamination,monitorshouldbecleanedwithsoft,dampcloth.
Monitorinsideshouldnotbeoodedwithwaterorotherliquidbecausethiscancausethe
equipment damage.
