It is forbidden to install the units without first reading the following
instructions.
I. GENERAL INFORMATION
CDNP is a door entry unit with digital dialling as well as apartment number display
and access control function (front door code opening). It features a large, blue
backlit LCD display and a blue backlit keyboard. A special sensor (only CDNP6
series) activates a display heater when the temperature drops (below 5oC) to
greatly improve display readability. The CDNP unit can be integrated to work with
conventional and electronic name display modules. It can also support different
external devices such as proximity card readers.
The device requires a double wire installations (audio version) or a T568B
standard UTP (Video version). They are suitable for use with uniphones featuring
digital decoding: INS-UP, INS-UP720, UP800 or INS-MP, INS-MP7 and
MP800/UP800V video inside units. It is possible to expand them with different
additional modules. They will also work with door entry units of other CDNP series
(Master / Slave mode).

4
CDNP housing is made of aluminium alloy to ensure effective protection against
devastation and weather conditions. CDNP units are easy to operate, functional,
their installation is simple and are adaptable to the changing requirements of
contemporary housing construction.
CDNP digital door entry units can be expanded to complex multi-entry systems
that combine a number of units, for instance residential estates with access
control, gate house, main gate, building entrances etc. In practice this makes it
possible to call an apartment both at the entrance to the site as well as the
entrance to a building or staircase. Their other advantage is the possibility to
individually program the ringing parameters for each apartment, by choosing one
of the four available signals and signal repetition in the ringing cycle. With two
pre-programmed additional numbers it is possible tocall one uniphoneusing three
different numbers (each with different ringing settings), such as in a tenement
house where one uniphone is used by several apartments on the same floor. The
units, with connected additional CDN-ACC module, also support door opening
using proximity cards and RFID key fobs (in Unique 125 kHz standard). Series "6"
units are also available with internal, built-in proximity key reader - the
CDNP6ACC version.
The control unit can also support control of an additional gate, etc., from uniphone
(button F2), by means of individual resident codes or proximity cards/key fobs (for
CDNP6 series master panels by means of built-in second relay output, for slave
panels by means of an optional CDN-I/O input/output module). With CDN-USB
cable and corresponding "CDNP" or "ACC" software (for key fob management by
CDNP6ACC) downloaded free of charge from www.aco.com.pl, it is possible to
program settings, create backups and transfer settings to other units. For detailed
information on the operation and capabilities of CDNP units refer to this manual.
Their other advantage is the possibility to individually program the ringing
parameters for each apartment, by choosing one of the four available signals,
signal repetition in the ringing cycle, door opening signal and automatic opening.
With eight programmed additional numbers it is possible to call one uniphone
using many different numbers (each with different ringing settings), such as in a
tenement house where one uniphone is used by several apartments on the same
floor.
Door entry units feature one built-in input activated by short circuit to ground. It is
used to connect an external “doorbell" button, such as INS-OB.
The default operating mode is direct opening of the door (E-lock activation) - for
instance when leaving the staircase. It is also possible to set door opening delay
or switch to direct call mode.

5
The door opening delay is programmable in installer's menu and the mode
settings can be changed using a computer software.
The units also feature a second built-in relay output (only CDNP6 Master units),
which can be used to control additional devices such as another gate, lighting,
etc. These additional devices can be controlled both from the uniphone (F2
button) as well as by using individual resident codes or proximity cards/key fobs.
Slave panels require an optional CDN-I/O input/output module with 2 NO/NC relay
outputs and two inputs activated by short circuit to ground. The CDN-I/O module
may also be used in Master panels and can support a number of applications,
described in the computer program or on the website.
The unit features an output for connection of a standard or reversible E-lock. Use
CDN-PK relay module to connect another device in place of the E-lock.
It is also possible to use one door entry unit to control two pairs of doors - to open
the right apartment door (CDN-I/O module required). Apartments can be freely
assigned for opening specific door.
Use the optional CDN-USB cable and the computer software that can be
downloaded free of charge from www.aco.com.pl to program settings, create
backups and transfer settings to other units. Unit settings can be managed using
the "CDNP" software, while proximity cards and key fobs - using the "ACC_v3x"
software.

III. OPERATION
In standby (factory settings) the unit displayshows "aco". Using the P22 software,
this can be changed to any other 6-character inscription or to 6 different screens
(6 characters each) can be entered using a PC, displayed in cycles with a fixed
interval. Heated display (CDNP6 series only) for better readability at low
temperatures.
To call an subscriber, their number must be selected using the keypad (the
number will appear on the display). Within 3 seconds the uniphone in the
apartment will start ringing.
First, the unit sends ringing tones (as set in P3 software - by default 2) and sets
itself to stand bywaiting for the handsetto be picked up. If the call is not answered
within 20s, another single signal is sent and the unit continues waiting for 20s.
While awaiting for the call to be answered, the display backlighting will blink. If
the uniphone handset of the selected apartment is not picked up within
approximately 40s, standby condition will be automatically cancelled and the
system will switch from calling to standby mode. Calling can be cancelled with the
“#” button.
If the handset of the uniphone is picked up at the apartment during the waiting
time, its connection with the unit will be established. The display will become
brighter. Now conversation is possibleand the entry doorcan be opened. The call
will last approx. 2 minutes unless the uniphone handset is hanged up or the
connection is terminated with the use of the "#" button.
Two additionalsupported numberscan be addedto the unit (program P15). These
can be any number in the range of 1-999, to which physical addresses of
uniphones can be assigned.

7
Additional numbers can assigned to the same uniphone so that it can be called
using three different numbers (for instance two additional numbers and one
primary number). Each such additional number may be configured with different
ringing parameters (ring tone, volume, number of signals). If the primary numbers
and additional numbers overlap, the latter have priority and calling in these cases
is always made according to their settings. Individual access codes for opening
are the codes in the table, corresponding to physical addresses of uniphones (set
in uniphone jumpers).
The unit detects a short-circuit of uniphone lines - displaying the flashing "LineEr”
message. During this time, E-lock can be activated by pressing any button and
building can be exited. When the correct state of the line is detected (when short
circuit ceases), the unit is automatically restored to normal operation.
An additional CDN I/O expansion module can be connected to the unit. It features
2 NO, NC relay outputs and two inputs activated by short circuit to ground. It can
be used to control lights in the hallway or open an additional gate, etc.
The unit features an output for direct connection of a standard E-lock or reversible
E-lock - in case of CDNP6. Use CDN-PK relay module to connect another device
in place of the E-lock.
The door can be opened:
1. With the “key” button on receiver
in the apartment
The door will open upon pressing the opening button ("key") on the receiver.
Typically, the door can be opened only during connection (conversation). During
one connection the door can opened three times (that together with enabling the
second output - F2), after which the connection will terminate automatically (the
parameter can be set to: 1, 2 or 3). The door can also be opened without having
to connect with the apartment - refer to the I/O module settings in the computer
program for details. In this case, on classic uniphones the handset must be picked
up and the open button pressed three times, on active receivers (INS-UP720MR,
UP800/MP800, INS-MPx) the open button must be pressed once.
2. With user’s access code
Use the unit keypadto select the apartment number, confirm with the "key" button
and enter the four-digit entry code for the apartment. The entry code is unique for
each apartment and can be easily changed. These codes are provided in tables.
Each table has its unique number, used to generate 255 different access codes
for residents.

8
Full table with residents’ codes or residents’ name tags together with use
instruction can be printed using the "ACO Code Generator" available at
www.aco.com.pl - user zone (“download"). A name tag may include a logo and
one line of text for company name and phone number etc..
In Master panels the code table is entered at the factory as a 4-digit number at
the back of the unit; the same table must then be entered in Slave panels. The
installer can check (in P1 program) the current value of each code and change it
if necessary. Users can also change this code by themselves (refer to P16 bit7
software for description and activation).
For the code table number "9999" opening with a user’s code is disabled.
3. With proximity card or key fob
Units with the ACC proximity reader can be used with proximity card or key fob
(resident’s or administrator/installer’s), programmed in the unit. A card or key
fob which is not programmed will generate a “beep” sound twice.
4. With administrator’s access
code
To get access using the administrator’s code, press the "key" button on the
keypad and then enter the six-digit administrator’s code. This code is used by
persons such as technicians, postmen, housekeepers, etc. In the P1 software it
is set as apartment No. 0.
5. With any key on the keypad in case of a malfunction
If calling an apartment is not possible due to a failure (such as short circuit on
uniphone lines - message: ”LineEr”), door can be opened with any key on the
keypad.
6. With additional external button
The unit features an additional input. If value 0 is set in the P12 software, this
input functions as additional opening - whenshort circuited, the E-lock is activated
for time set in the unit (delay is configurable). Such opening while the call is
pending completes the procedure of calling the apartment.
Any NO button, code lock, motion detector etc. can be connected to this input.
The input is protected against a permanent circuit short-circuit (short circuit
triggers it’s disconnection from the system until released).

9
7. Further door opening function in Slave panels.
The slave unit features the so called afurther door opening function. In the master
panel, after opening the door and ending the conversation, or opening with a
unique code (or proximity card), downstream Slave unit automatically activate the
"waiting time” (marked with the key symbol on the display; the signal also activates
waiting time countdown). During this time, pressing the "key" button activates the
E-lock. This option is possible only in those slave units through which the
connection was made. When opening with a unique code (or proximity card), in
those units that must be passed to reach the apartment to which the openingcode
(or card) is assigned. Standby mode can be cancelled with the "#" button. If bit 1
in P16 is set to ON, the E-lock will automatically engage after the pre-set delay
time has elapsed. The waiting time is set in P6 of each slave unit. The further door
opening pulse must be enabled (bit 4 in P16) in the master unit. For more
information, refer to the P6 andP16 program description - bit.1 andbit4. By default
this function is disabled.
8. Input from additional module.
For this unit door opening is also possible via an additional module such as: CDN
I-O, CDN ACC proximity card and key fob reader, or internal proximity key reader
(CDNP6ACC) built into the unit.
9. Automatic opening when calling
Automatic door opening after the first ringing tone. When the handset is not hung
up and this function is enabled, the door will open automatically after the first
ringing tone. Ifthe handset was hung upduring the first ringing tone, the unitworks
normally - the handset can be picked up and communication is possible. This
function most commonly used in commercial buildings - letting people in is done
by simply lifting the handset; after business hours the handset is hung up and the
door entry unit works normally. For more information, refer to description of
additional numbers - P15 program.
When the E-lock is being opened the display shows "Enter” (for persons with
hearing impairment) and a signal is heard from the loudspeaker (for persons with
sight impairment).
The E-lock operation time and delay can be changed in P6 (by default it is 4
seconds without delay).

10
Control of the built-in second relay OUTPUT:
The OUTPUT exit (CDNP6 Master units only) can be activated upon pressing the
F2 button in the receiver or entering the usercode - in which case the "key" button
must be pressed twice before entering the code, which is the same as the basic
access code. Typically, exit is possible only during the connection (conversation).
Exit can also be activated without having to connect with the apartment - refer to
the I/O module settings in the computer program for details.
In this case, on classic uniphones the handset must be picked up and the open
button pressed three times, on active receivers (INS-UP720MR, UP800/MP800,
INS-MPx) the open button must be pressed once.
The response time and functions of the OUTPUT exit can be changed via the
computer program (similar as for port 2 of the CDN-I/O module). The default
response time is 1s. Slave panels must feature an optional CDN-I/O module.
At exit the display shows “OUT-2”.
Exit control for individual premises can be disabled.
In units with the ACC proximity reader, the second output can also be activated
without pressing the "key" button and the proximity card or proximity key fob
(resident’s or administrator/installer’s).
The unit detects a short-circuit of uniphone lines - displaying the "LineEr”
message. During this time, E-lock can be activated by pressing any button and
building can be exited. When the correct state of the line is detected (when short
circuit ceases), it is automatically restored to normal operation.
Refer to the "Solving common problems" section at the end of this manual for
more information and description of common problems.
IV. DESCRIPTION OF ADDITIONAL AND SPECIAL MODULES
The CDNP door entry units support a great number of additional and special
modules. Additional modules can be added independently (can be purchased as
separate modules).
NOTE! Modules may only be connected with the power supply switched off.
The following module types are available:
230E module - electronic resident list module. Names
(16 characters in the top line and 11 in the bottom line)
are arranged alphabetically and can be viewed on the
LCD display using two buttons. It only displays
apartments with assigned tags (names). Pressing the
bell button activates calling the name being displayed.

11
The display time is limited to some 10s. After 10 seconds the display switched to
Intro, where any text can be typed in two lines of 16 characters each, for instance
building address, name, servicing company telephone number, etc. Upon
selecting the apartment number on unit’s keypad, the display will show relevant
data for that number. The module needs to be connected to the "EXTMOD1" or
"EXTMOD2" input of the unit and programmed directly from the keypad (P19
program) or via the special CDN-USB cable and using the appropriate software
("230E") which can be downloaded free of charge from www.aco.com.pl (Note:
for modules version 7.00 and above, programming is possible via a PC only). 4
different start screens can be uploaded using this software (2 x 16 characters);
they will be displayed in sequence at the interval of 1s to 15s, depending on the
setting.

CDNVK module - camera module used in CDNV video
door entry system.
The module features a built-in high-resolution colour
camera (min. 600 lines) with a 2.8 mm wide angle lens.
It features IR LED (infrared) backlight that automatically
switches on after dusk and ensure image visibility in the
dark (monochrome). The video output of the camera is
a PAL (symmetrical) signal, so it requires a combiner,
which can be connected the camera module.
Typically, the combiner is installed directly in the door entry unit and provides
power supply to the camera module as well as converts the PAL signal into a
differential signal transmitted in ACO video door entry system bus, based on UTP
(min. cat 5e). This type of bus is used for all video inside units.

Slave panels.
Combiner modules are connected only to the "EXTMOD2" port (top
port).
CDN-U signalling module with opening
function
This module can be used to connect additional
devices signalling ringing in the apartment, for
instance additional bells, light bulbs etc. for
persons with hearing impairment. The module
also enables remote or automatic door opening
without picking up the handset.
The module can operate independently (built-in sounder) and in parallel with
uniphone. For proper operation power supply must be connected from a separate
10.5 - 12V~ transformer or 12V power supply unit (voltage from the "EXTMOD"
connector can be used), uniphone lines must be connected to the L+, GND
terminals and proper apartment number needs to be set using switches. The
output of the module are NO contacts of 1A relay. To open the door, connect a
bell (monostable) NO switch to the INPUT and GND and set the switch to the
"ON" AUTO position. Short circuiting this input permanently will automatically:
answer the call, open the door and end the call. When the AUTO switch is in the
"OFF" position, the module will short circuit the OUTPUT when ringing. The
module has a built-in buzzer, activated by the "Buzzer" switch.

15

This module features two programmable
ports: P1 and P2. Each of these ports has an
INPUT and a relay OUTPUT.
Inputs can be used for calling or opening and
outputs can be used as control of opening an
additional entrance gate, switching on the
staircase lighting, etc. Module parameters
are set using the P18 program. Refer to page
52 for module configuration description.
V. OPERATION OF THE CDNP UNIT
The unit can be used with uniphones featuring digital decoding, such as:
INSPIRO, INS-UP720 or INS-MPR type (3.5 inch and 4 inch) monitors.
Terminals of all uniphones are connected in parallel to corresponding "Line +"
and "-" terminals of the unit. For video systems, the monitors should be
connected via active splitters (CDNVRa). In the standby mode of the unit, the
voltage on uniphone line (audio line) is approx. 9V, while during calling it goes
up to approx. 12V.
As the handset is picked up (uniphone activated), the line is loaded and the
voltage drops to approximately 5 V, which the unit recognises as permission to
connect the call. If voltage drop below 5V other then during a connection or a call
is recognised as a short-circuit by the unit - the display shows “LineEr”. The line
is then de-energised and checked, at certain time intervals, if the short circuit is
still present. When the correct state of the line is detected (when short circuit
ceases), the unit is automatically restored to normal operation.
The E-lock is controlled by AC voltage generated by the unit and specially formed
for this purpose, therefore it is possible to supply the unit with DC voltage source
- for instance a buffer PSU with a battery.
VI. INSTALLATION OF THE UNIT
Install the unit on building wall (vestibule, sheltered wall, east wall, etc.) so that to
minimise the effect of adverse weather conditions. The recommended height of
installation of the unit is such that it can be used by children (some 1.35 m) and
persons with disabilities (persons with sight impairment, in wheelchairs, etc.).
Make sure that the panel of video systems is installed at the desired height.
Typically that height is 1.60 m from the ground. For optimal field of view of the
camera, verify the installation location and position of the panel by trial and error.

16
Avoid locations where the camera lens may be exposed to direct, perpendicular,
light (from the sun, street lamps, etc.).
The base plate for surface mounting of the unit is installed to the floor with
rawlplugs or appropriate screws. Install the flush-mounting frame of the unit in the
appropriate wall opening using rawlplugs and gypsum (wait for the gypsum to dry
before screwing the outside unit to the mounting frame). Lead the wires through
the holes in the frame.
Auxiliary holes around the frame are used
for makeshift installation with nails etc. when
mounting the unit in soft materials such as
polystyrene. These holes also help when
mounting the unit using mounting foam.
Upon completion of the installation the top
holes of the frame must be plugged (with
mounting foam or plaster). Then screw
evenly all screws of the housing to the frame
using a 3mm Allen wrench.
- CONNECTIONS
Connect the following wires to the unit:
•2 wires x 1mm2- power supply to the transformer - for the Audio system or
power supply for the DC adapter (15VDC) of the Audio/Video system
•1 wire in yellow green insulation - to connect the housing's grounding
•2 wires x 0.75mm2- to E-lock,
•2 wires x 0.5mm2of intercom cable to connect receivers - for Audio system
or
•1 x UTP cable (min. cat 5e) - for the video system (the first master unit in
the system)
•2 x UTP cable (min. cat 5e) - for the video system (further slave units in
the system)
Note! all RJ45 plugs on UTP must be crimped in T568B standard.
Maximum lengths of signal cables (of the line or bus). The cross section
(resistance) of the bus for digital transmission and audio track (LINE terminals)
has a significant impact on the maximum bus length for both Audio and Video
systems. For typical cable cross sections (0.5mm) the maximum distance is 300
m. This distance increases with increasing wire cross section:

17
- with 1 mm2wire the distance can be increased to 400 m
- with 1,5 mm2wire the distance can be increased to 600 m
- with 2,5 mm2wire the distance can be increased to 1000 m
Use CDNV-RJ45 module to increase the cross-section of the above mentioned
cables (UTP) in the video system. When necessary, the video signal should also
be amplified with a separate device.
The maximum lengths of the other cables are described below.
It is recommended that the connection between the unit and the E-lock and the
power transformer be made using a 1 mm2cross-section cable (such as LY1,0).
Use similar cable to connect power supply of video systems (15VDC) to the
combiner located in the unit frame.
PLEASE NOTE! To ensure proper functioning and use safety, connect the
door entry unit (in metal frame) in its installation point to earth by
connecting the grounding terminal on unit’s body with relevant protective
installation (PE).
For wires of other cross-sections use the following formula to calculate the
voltage drop:
2 x L[m] x I[A]
U = ---------------------------- [V]
57 x S[mm2]
Where: L - wire length from the unit to the transformer, e.g.: - 15m.
I - current - unit during opening - 0.44A (with backlit name tag
module)
S - cable cross-section e.g.: - 1.0 mm2
2 x 15 x 0.44
U = --------------- = 0.23V
57 x 1.0
PLEASE NOTE! The maximum voltage drop is 1.2V, or 10% of power supply
voltage. The maximum cable length for E-lock circuit is 7 m, for power supply
circuit - 15 m. Too small cross-sections and extensive wire lengths may cause
voltage drops during connections or opening (E-lock release), leading to
interference or resetting (restart) of the unit.
2. Power supply connection:
In case of passive audio receivers (2-wire receivers) the door entry unit issupplied
from a mains transformer, the supply voltage is 11.5VAC, connection to AC/AC
terminals (12V~). Recommended mains transformer is TR 11.5V 1.2A or TR DIN
11.5V 1.2A, available from ACO.

18
In case of active audio receivers (that require power supply), the door entry unit
uses 15VDC DC power supply, connection to +DC (ELOCK+) and GND (LINE-)
terminals. Same can also be used for passive receivers.
For VIDEO systems, 15VDC supply voltage is connected to combiner module
terminals: +15V and GND. In both cases the recommended power supplies are
available from ACO.
It is possible to connect a buffer power supply to the same terminals (buffer power
supply must ensure 15V, alternatively use an off-the-shelf inverter that supplies
15V from 12V to 15V input voltage).
3. Connecting the E-lock:
E-locks without any specific polarity are connected to "ELOCK" output terminals.
This output is used for direct connection of the E-lock; it generates AC voltage
during opening (hence the outside unit may be supplied from a DC voltage
source). It is recommended to use (non-reversible) E-locks that work on 8V to
12V.
It is also possible to connect a reversible E-lock (opens when de-energised). This
option can be activated by in the installer's menu No. P10 and upon closing the
Z13 jumper (if presnet). In this case, "ELOCK" is energised when in standby and
de-energised during opening. When power supply is provided from a transformer
and a reversible E-lock is used, transformer power is calculated using the
following formula: P[W] = (12V * E-lock current [A] + 4W) * 1.6. Insufficient
transformer power causes "buzzing" during conversation. 15VDC power supply is
recommended. Note! In case of reversible E-locks, voltage appears at the
"ELOCK" output depending on the power supply or transformer used - use
suitable reversible E-lock. It is also possible to use the MOD-DC-12V module for
12VDC power supply of reversible E-lock if the door entry unit is supplied by a
15VDC power supply or a transformer.
4. Connecting another device in place of an E-lock:
If E-lock needs to be replaced by another device instead, use a relay (12V coil)
connected to "ELOCK" terminals with an additional 100 - 470µF electrolytic
capacitor (depending on relay type), as per the diagram:

19
ACO offers off-the-shelf CDN-PK modules.
Relay contacts can be used as needed - it is recommended to power the unit
connected to relay contacts from a separate power supply. Do not connect other
inductive loads (such as an E-lock) via a relay from the same transformer that
powers the door entry unit.
5. Connection of the receivers (wiring - topology):
Refer to chapter V for details on receiver wiring.
Passive audio receivers (2-wire) are wired using a 2-wire intercom cable, and the
terminals of all receivers are connected in parallel and connected to the "LINE"
terminals of the door entry unit. Make sure that + terminals of the receiver are
properly connected to LINE+ of the door entry unit and -terminals of the receiver
properly connected to LINE - the door entry unit. Improper wiring of even one
receiver will cause bad operation of the entire system.
Same with active audio receivers that need two additional wires for power supply.
All power and LINE terminals of the receivers are to be connected in parallel. In
small systems one power supply will support both the receiver and the door entry
unit - in each case a DC power supply. For larger installations that require
additional power supplies for receivers, LINE and -DC (GND) terminals of all
receivers should always be connected in parallel then connected to door entry
unit, and the +DC to -DC terminals for additional power supplies.
For Video systems, the entire wiring must be made using UTPs in T568B
standard, min. cat 5e standard (all wires to be used); these systems also require
optional combiner modules: for Master devices: CDNVS, for Slave devices:
CDNVSp.
Note! All UTPs should be ended with an RJ-45 plug, making sure that the same
wire sequence is maintained.
UTP should origin at the door entry unit (combiner output), to the main input of
the first splitter, then the main output of the splitter is to be connected to the main
input of the next splitter and so on. The last splitter must be a terminal splitter or
a video terminator jumper.
All splitter in video systems must be active and the monitors are to be connected
using relevant outputs of the splitter. Monitors on cat 5e UTPs should be
connected at a distance of 70m or less from the connection point, while the whole
system must remain within 300 m. Additional power supplies can be connected
directly to the splitters - then the right jumper in specific splitter must be removed.
Another way to wire the installation is to keep all active splitters in one place and
branch to each monitor.

20
In system with multiple video door entry units (Master / Slave), panels must also
be connected with UTPs.
In simple video installations with only power supply unit (connected to the
combiner), the maximum distance between the door entry unit and terminal
monitor is 70 m. Connect additional power supplies to distributors or directly to
monitors in order to couple monitors over longer distances.
With additional wires (refer to the beginning of the chapter for information) and
with CDNVRau-DIN active splitters (offered by ACO) to amplify the video signal,
video installations may have up to 1000 m.
Typically, the monitor is powered using UTPs (double pair) via a combiner,
intermediate combiner or splitter and turns on automatically when its address is
called, and turns off when the connection is ended. In this setup one 15VDC /
2.8A power supply supports 5 splitters. When the option of image viewing at any
time is enabled in the monitor (without having to call from the panel), the monitors
should be powered via splitters following the rule of one 15VDC / 2.8A power
supply per 8 monitors. When several monitors may call at the same time (have
the same address) this must be taken into consideration when selecting the
number of power supplies (assume one 15VDC / 2.8A power supply per 6
monitors calling at the same).
Combiners supply power to the door entry unit via a ribbon cable connected to
the EXTMOD2 port. Combiners can be installed at a further distance from the
door entry unit - in which case the door entry unit must be supplied using a
dedicated wire: +DC and GND panel terminals connected to +15V and GND
combiner terminals . In CDNVS combiner the ribbon cable needs not be plugged
in. InCDNVSp intermediate combiner the ribbon cablemust be plugged in(control
of the camera image in slave door entry unit) - use the ARK-RS module, offered
by ACO, as ribbon cable extension.
Refer to chapter "Connecting more door entry units in the system" for more
information on master/slave systems. Visit www.aco.com.pl to download sample
video installation diagrams.
6. Before initial power-up:
When wiring is completed and verified as correct (use a meter to check for
possible short circuit in the uniphone line and between other terminals). Before
plugging UTP to the monitor, splitter and combiner, it is absolutely necessary to
check if all RJ-45 plugs are properly crimped, check for short circuits between
wires and for continuity of cables.
