Introduction
The VK4K Series is a new range of videokits that use the 4000 Series external door station and the Art.6458 Series videophone.
The camera / audio unit is the size of a single 4000 Series module and is available in either ush (VK4K) or surface (VK4K-S) mounting
versions.
As a result of using microprocessor technology in the door panel and videophone, a number of additional features have been add-
ed to enhance the operation of the videokits and give greater feedback to the visitor and user.
• Disability friendly, visual and acoustic signals from the door panel to inform the visitor of call status (call made, ringing, speak,
door open).
• Programmable door open and conversation time.
• Expandable to 4 entrance panels (requires an additional relay Art.506N for each entrance panel).
• Connections for a push to exit button.
• Two methods of operating the electric lock:- 1) Dry contact relay, 2) capacitor discharge 12Vdc output.
• Facility for the connection of a codelock Art.4800M, display module Art.4820, stand-alone proximity reader Art.4850 or stand-
alone biometric reader Art.4821 etc.
• Programmable number of call tone rings from 2 to a maximum of 8.
• Input for local door bell push button.
• Programmable timed privacy function from 15 minutes to a maximum of 8 hours.
• Door open status LED (additional wire required from the door to the videophone)
• Up to 4 videophones can be connected in parallel, all with intercommunication facility.
• Videophones can have a maximum of two additional audio telephone handsets connected in parallel.
• Camera recall on all systems, with selective recall on systems with multiple entrances.
• Door panel camera can be adjusted horizontally and vertically (10 degrees).

In case of system failure, try the following preliminary checks:
• Check that the cables are connected as shown in the installation diagram and that the cables are rmly xed into the relevant terminals;
• Check that the mains voltage is available on terminals 230Vac (or 127Vac) and 0 of the power transformer Art.850K;
• Check the 24Vac voltage output of the power transformer Art.850K. If this voltage is not available it could be the 1,6A fuse, in this case
remove the mains voltage, remove possible short-circuits or overload sources then replace the fuse with an equal or equivalent one.
• Check that the voltage between the terminals“+” and “-” of the speaker unit is between 16 and 20Vdc.
If the problem persists try the tests in the following table or contact technical support.
SYMPTOM CAUSE SOLUTION
The door station is not able to call the ex-
tension (the bell LED is switched on for 2
seconds):
• Wrong connection between door sta-
tion and the videophone
• Cable size too small.
• Programmed videophone address in-
correct.
• You have changed the videophone ad-
dress without power down the system.
• Check the 6 common wire connections
especially wire“1”(speech line/data).
• Increase cable size or double up using
two wires for each connection.
• Check videophone address on dip-swi-
tches.
• Power down the system then power up
again to detect the new videophone ad-
dress.
External call works but when answered
the communication fails:
• Cable size too small. • Increase cable size or double up using
two wires for each signal.
During the conversation it is not possible
to open the door:
• Cable size too small. • Increase cable size or double up using
two wires for each signal.
During the conversation it is not possible
to open the door but the key LED on the
door station switches on for the program-
med time:
• Incorrect position of J2 jumper.
• Electric lock wires unconnected or in short.
• Wrong electric lock type.
• Check J2 position on the door station.
• Check connection.
• Check that the electric lock type (ac or dc)
is suitable for the J2 position chosen.
Speech only from outside to inside: • Wire “2” broken or in short. • Check connection of wire“2”.
Low volume of speech: • Volume trimmers of door station require
adjustment.
• Adjust the trimmers until the required
volume is reached.
Noise over the speech line during the con-
versation:
• The 6 common wires are cabled to-
gether with 230 or 380Vac power lines.
• The 6 common wires are cabled to-
gether with 24Vac videophone power
supply wires.
• Separate the 6 common wires from the
high voltages cables.
• Separate the 6 common wires from the
two 24Vac wires or cable them together
only for a short distance.
Camera recall service does not work: • Camera recall button pressed for a num-
ber of times dierent from the ID of the
door station to be switched on.
• Check the ID (1..4) of the door station to be
recalled and press the camera recall but-
ton as many time as the ID value.
Intercommunicating call does not work: • ”Key” button pressed for a number of
times dierent from the videophone ad-
dress value.
• Check the address of the videophone
you are calling and try again.
The video shown on the monitor is of a bad
quality and the image is distorted or double
• V1,V2 signals unconnected, reversed or
shorted.
• The switches of the two way dip-switch
are not both in ON position.
• V1,V2 of the last Art. 316N (if present)
not closed with 75 Ohm resistor.
• Check that the wires are not broken or
shorted.
• Set both switches to the ON position.
• Use 2x 75 Ohm resistors to connect V1
& V2 to 0V.
Local call does not work: • Wrong connection or call button broken. • Check connection or replace the button.

When the door open relay operating mode is set to “capacitor discharge”*, one terminal of the electric lock must be connected to
ground while the second must be connected to“NO”terminal. The“NO”terminal will supply a temporary voltage when the speaker
unit receives the door open command.
* When “capacitor discharge” operating mode is set, one terminal of the electric lock must be connected to the ground while the
second one must be connected to“NO”terminal. The“NO”terminal will supply a temporary voltage when the speaker unit receives
the door open command (we suggest to use a 12Vac/dc 1A max electric lock). Setting “dry contacts” operating mode, when the
speaker unit receives the door open command, the “NO” terminal will be internally linked to the “C” terminal for the programmed
time (switch 4 of the 4 way dip-switch bank).

BUILTIN RELAYS  BACK EMF PROTECTION
The Art.4833 includes selectable back EMF protection on the relays. The jumpers marked J4 (One jumper for each relay) are used to
select the protection type. When using a fail secure lock with connections C & NO the jumper should be in the NO position. When using
a fail open lock with connections C & NC the jumper should be in the NC position and when using the codelock to trigger a gate con-
troller or another third party controller the jumper should be removed completely (This disables the protection on the relay).
LOCK RELEASE BACK EMF PROTECTION
A varistor must be tted across the terminals on AC lock release
(Fig.1A)
and a diode must be tted across the terminals on a DC
lock release
(Fig.1B) to suppress back EMF voltages. Connect the components to the lock releases as shown in gures.

CODELOCK UNIT MODULES ART.4800M
The module features 12 stainless steel buttons (Keys 0 - 9,
ENTER and CLEAR), 2 LED’s for progress information during
use and programming and a mirror nish stainless steel front
plate (Standard version). With three integral relays each with
common, normally open and normally closed connections and
two inputs to enable the external triggering of relays one and
two (For example, push to exit button). Key presses are signalled
both acoustically and visually while each button press has a tac-
tile feel. Entering the correct code followed by ENTER will ac-
tivate the relevant relay. Programming is carried out through
the same keypad following a simple programming menu. The
module can be combined with other 4000 Series modules in an
audio or video intercom system.
‘
MAIN FEATURES
• 3 C, NC, NO relay outputs (24Vac/dc – 5A max);
• 3 Programmable secret codes (one for each relay);
• Each relay can be set to be activated for a specic time (01 to 99 seconds) or to work as latch;
• Two active low inputs to command directly the relay 1 and 2;
• Programming menu guarded by a 4-8 digit programmable engineer’s code;
• Visual and Acoustic signal during operating and programming;
• Keypad illumination LEDs;
GENERAL DIRECTIONS FOR INSTALLATION
In order to achieve the best results from the schematics described it is necessary to install only original VIDEX equipment, strictly
keeping to the items indicated on each schematic and follow these General Directions for Installation:
• The system must be installed according to national rules in force, in any case the running of cables of any intercom unit must be
carried out separately from the mains;
• All multipair cables should be compliant to CW1308 specication (0.5mm twisted pair telephone cable).
• Cables for speech line and service should have a max resistance of 10 Ohm
• Lock release wires should be doubled up (Lock release wires and power supply wires should have a max resistance of 3 Ohm);
• The cable sizes above can be used for distances up to 50m. On distances above 50m the cable sizes should be increased to keep
the overall resistance of the cable below the RESISTANCES indicated above;
• Double check the connections before power up;
• Power up the system then check all functions.
LOCK RELEASE BACK EMF PROTECTION
A varistor must be tted across the terminals on AC lock release
(Fig.1A)
and a diode must be tted across the terminals on a DC
lock release
(Fig.1B) to suppress back EMF voltages. Connect the components to the lock releases as shown in gures.

BUZZER BACK EMF
When using intercoms with buzzer call (Art.924/926, SMART1/2, 3101/2, 3001/2 and 3021/2) add one 0.1uF (100nF) capacitor be-
tween terminals 3 and 6 on the telephone.
BUILTIN RELAYS  BACK EMF PROTECTION
The Art.4800M includes selectable back EMF protection on the relays. The jumpers marked MOV (One jumper for each relay) are
used to select the protection type. When using a fail secure lock with connections C & NO the jumper should be in the NO position.
When using a fail open lock with connections C & NC the jumper should be in the NC position and when using the codelock to
trigger a gate controller or another third party controller the jumper should be removed completely (This disables the protection
on the relay).

4000 Series Surface and ush mounting door station installation
INSTALLING A SURFACE MOUNT DOOR STATION
1. Place the surface box against the wall (165-170cm between the top of the box and the oor level as shown in Fig.1) and mark the
xing holes for the wall plugs and the hole for the cables E (g.2). Observe the orientation of the box with the hinge on the left;
In order to prevent water ingress we highly recommend using a silicon sealant between the wall and the back box C
(Fig.3) and around all holes D (Fig.3);
2. As shown on Fig.2, drill the xing holes A, insert the wall plugs Band feed the cables Ethrough the surface box opening D, x
surface box Cto the wall using the screws F;
3. Apply the Ysilicon sealant on top of each module as shown in Fig.4;
4. Before installation of the module support frame, hook the modules Gto the support frame Has shown in Fig.5 then, as shown
in Fig. 6, t the two anti-tampering locks Wfor each module (do the same for the second module support frame);
5. When you have more than one support frame, hook the support frame to the surface box starting from the left. For convenience we
will described how to attach the left frame but the same must be carried out for the right frame. As shown in Fig. 7, hook the module
support frame H(complete with modules) to the surface box Cmoving the frame as suggested from pointers. Ensure that the pivots
L (Fig. 7) go inside the relevant housing Mas shown in Fig. 8;
6. As shown on Fig. 9, pull back the module support frame Hwhile moving it slightly to the left as suggested by the pointers;
7. As shown in Fig. 10, open the module support frame Has suggested by the pointer, hook the hinge locks Nto the hinges M,
make the required connections using the screwdriver provided P(at blade end) and make the required adjustment by adjust-
ing the settings (through openings O) and adjust trimmers;
8. Repeat the same operations described above for the second module support frame (or for the third if available);
9. When the system has been tested and is working correctly, move back the module support frames carefully, x them to the surface
box using the screwdriver provided P(torx end) and the pin machine torx screws Q (Fig. 11). Note: do not over tighten the screws
more than is necessary.
INSTALLING A FLUSH MOUNTING DOOR STATION
When ush mounting and the number of modules is greater than 3, the required back boxes need to be linked together (before
embedding them in the wall) as shown on Fig. 14, 15 and 16:
• Arrange the back boxes and remove knockouts to allow cables to be fed from one back box to the other;
• Hook the spacers to rst back box then hook the second back box to obtain the result shown on Fig. 16;
1. Protect the module support frame xing holes from dust then embed the back box into the wall (165-170cm between the top
of the box and the oor level as shown on the Fig. 1) feeding the cables E (Fig. 2) through a previously opened hole in the box.
Observe the direction of the box ensuring the hinge is on the left and take care that the box prole is in line with the nished
wall prole;
In order to prevent water ingress we highly recommend using a silicon sealant between the wall and the back box H
(Fig.12);
2. Continue from step 4of surface mounting instructions , but at step 7hook the hinge locks Nas shown on Fig. 13.
Note: if additional holes are made in the surface box, oxidation problems may appear unless the unprotected metal is
coated with a protective paint.
NOTES
• The screwdriver’s blade has two sides, one at and one torx, to select one of them unplug the blade from the screwdriver body
and plug it into the required side.
• The example shows the use of only one back box bottom hole for wires, this is done to keep le drawings clear. Naturally the
installer can use the left hole or the right or both if required.
HOW TO REMOVE THE CARD NAME HOLDER
• To avoid damage to the module front plate, tape the side that will be in contact with the screwdriver blade;
• lnsert the screwdriver (at side) into the card-holder hole as shown in Fig. 17;
• Move the screwdriver to the left as shown in Fig. 18 to extract the card name holder;
• Edit the card name then replace it inside the holder and ret: insert the holder inside its housing from the left or right side then
push the other side until it clips into place.
