General directions for installation
CONNECTION TO MAINS
The system must be installed according to national rules in force, in particular we recommend to:
• Connect the system to the mains through an all-pole circuit breaker which shall have contact separation of at least 3mm in each
pole and shall disconnect all poles simultaneously;
• The all-pole circuit breaker shall be placed for easy access and the switch shall remain readily operable.
POWER SUPPLY INSTALLATION
• Remove the terminal side covers by unscrewing the retaining screws;
• Fix the power supply to a DIN bar or directly to the wall using two expansion type screws;
• Switch o the mains using the circuit breaker mentioned above and then make the connections as shown on the installation diagrams;
• Check the connections and secure the wires into the terminals;
• Replace the terminal covers and x them using the relevant screws;
• After completing the wiring, double check all connections then restore the mains.
CABLE SIZE
Video connections and Audio connections must be wired in twisted pair: pair the video lines (terminals/signals V1 and V2), pair
the audio lines (terminals /signals 1 and 2).
IMPORTANT NOTE: SOLID COPPER CABLES MUST BE USED. COPPER COATED STEEL CCS AND COPPER COATED
ALUMINIUM CCA CAN NOT BE USED ON THE SYSTEM.

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 powering 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 2broken 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.

BUILTIN RELAY  BACK EMF PROTECTION
The Art.4833 includes selectable back EMF protection on the relay. The jumpers marked J4 is 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 used to trigger a gate controller or another third party con-
troller 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 ter-
minals on AC lock release (Fig. 3) and
a diode must be tted across the ter-
minals on a DC lock release (Fig. 4) to
suppress back EMF voltages. Connect
the components to the lock releases as
shown in gures.

HOW TO CONNECT ELECTRIC LOCK
The“door-open” relay can operate either as“dry contact” or “capacitive discharge” mode.
• In “dry contact”operation mode the relay works in a traditional way, a power supply or a power source is needed to operate the
lock (12-24Vac/dc 2A max), and activation lasts according to the door opening time programmed.
• In “capacitive discharge” operation mode the relay’s contacts, when active, supply directly the lock (12Vac/dc 1A max) for a mo-
ment. You don’t need a power supply for the lock and the door opening time programmed does not aect the activation time.
A possible deterioration of the mechanical performance of the electric lock, might cause the“capacitive discharge”to malfunction in time. In case
the electric lock is used in very dusty environments or in peculiar climate conditions, we suggest to use the lock in dry contact mode.

DESCRIPTION
The Art.4901 is manufactured from 316 grade brushed stainless
steel and the module features 12 stainless steel buttons, backlit
in blue (Keys 0 - 9, ENTER and CLEAR) and 2 LED’s for progress
information during use and programming. 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 tactile feel. Entering the correct code followed by ENTER will activate 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 ter-
minals on AC lock release (Fig. 5) and
a diode must be tted across the ter-
minals on a DC lock release (Fig. 4) 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.4901 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).
BACK LIGHT ADJUSTMENT JUMPER JPL
The jumper JPL (Fig. 2, D) is used to
adjust the brightness and determine
the operation of the backlit buttons.
There are four brightness settings for the
backlit buttons and two programming
modes (Mode 1 and 2) for the jumper.
The two modes that can be programmed
change the functionality of the jumper
JPL. The table beside indicates the
programming mode, the position of the
jumper and the operation of the backlit
buttons.

2. Short out terminals and SW2;
3. Press and hold down button 1and keep it pressed down
while the power is switched back ON;
4. When power is restored to the codelock wait for the module
to emit a single beep and the red status LED (Fig. 1, B) to
ash once;
5. Listen for the conrmation tone and wait for the red status
LED (Fig. 1, B) to ash once again;
6. Release button 1and remove the short between terminals
and SW2;
7. Set the jumper JPL to the desired position.
PROGRAMMING MODE 2
Follow the steps below to set the codelock to Mode 2:
1. Disconnect the power from the Art.4901 codelock;
2. Short out terminals and SW2;
3. Press and hold down button 2and keep it pressed down
while the power is switched back ON;
4. When power is restored to the codelock wait for the module
to emit a double beep and the red status LED (Fig. 1, B) to
ash once;
5. Listen for the conrmation tone and wait for the red status
LED (Fig. 1, B) to ash once again;
6. Release button 2and remove the short between terminals
and SW2;
7. Set the jumper JPL to the desired position.
BACK LIGHT AND BUTTON OPERATION
If the back light programming mode is set to Mode 1 (with jumper JPL in either the Aor Bposition) when a button is pressed on
the keypad the back light will switch to full brightness for approximately 10 seconds.
After this time the back light will either switch OFF or switch back to low brightness (depending on the jumper position) unless another
button has been pressed within the 10 second period in which case the back light will stay on full brightness for a further 10 seconds.
The exception to this is if the back light programming mode is set to Mode 2, i.e. the back light will be on full brightness all of the
time or if the jumper is removed the back light will be disabled.

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
ON THE LEFT, TOP AND RIGHT SIDES ONLY AND AROUND ALL HOLES D.
DON’T USE SILICON SEALANT ON THE BOTTOM SIDE OF THE BACK BOX (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 adjusting 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 module support frame
Hand the back box ON THE LEFT, TOP AND RIGHT SIDES ONLY.
DON’T USE SILICON SEALANT ON THE BOTTOM SIDE OF THE MODULE SUPPORT FRAME (Fig.12);
2. Continue from step 4of surface mounting instructions , but at step 7hook the hinge locks
N
as 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.
