ART.138N AMPLIFIER UNIT FOR THE VX2200 SYSTEM
The Art.138N is a functional digital amplier unit based on the “2 wire” BUS intercom for the VX2200 system.
Although the Art.138N amplier unit can be connected up to 24 call buttons the 25H/SP/DDA/2W panel will
already have a US91-15 DDA friendly braille push button pre-wired into the J1 and J2 button harness (using
the yellow (1) and white (A) wires).
The amplier can be congured as a MASTER
or a SLAVE panel depending on the number of
Art.138N ampliers connected on a system, this
can be done by adjusting switch 1 on the 8 way
dip-switch. The default setting is MASTER (switch
1 in the ON position).

BALANCE
Switches 6, 7 and 8 are used to setup the device
number of the Art.138N (these switches are usually
only set when there is a VX2210 concierge unit on
the system where the intercom panel making the
call needs to be identied on the concierge. It is
also used on video systems when camera recall is
required for each door).
Volume Adjustments
There are three adjustable POTs available on the Art.138N amplier module for speech volume adjustment.
This system uses only one wire to carry both directions of speech and so it is necessary to use the balance
POT to adjust the gain of the two speech directions to the required levels*.

(*Volume adjustment tip: set the speaker and mic POTs to approximately a third of a turn and then during ‘live’
speech adjust the balance POT whilst rubbing the bottom of the mic cap. Continue adjusting the balance POT to
the point at which the minimum volume of speech comes through the door panel’s speaker. Finally adjust the
speaker and mic POTs to optimal level ensuring that no feedback occurs when the panel is placed back into the
back box).

CABLE REQUIREMENTS
The 25H/SP/DDA/2W audio kit follows the same cable requirements for the VX2200 (audio) system. The
following tables below show the minimum number of cable cores required for this audio kit.
Table B
Connection Min.
Cores
50m 100m 200m 300m
Art.3171 2
3 pair CW1308
or CAT5e
4 pair CW1308
or CAT5e
4 pair CW1308 or
4 core 0.5mm² YY
4 core 0.75mm² YY
(*2 Please Note: It is perfectly acceptable to use an equivalent cable type if a CW1308, CAT5e or a YY cable is
not being used providing it meets the same cable characteristics as those described above and those shown
in table B).
The Art.521 power supply should be located as close to the door panel as possible, typically between 20 to
30m (max.). The location of the power supply can also serve as a central point for the Art.3171 audiophone
connections. Any electric door lock and push-to-exit connections can be cabled directly back to the intercom
door panel. If tting a break glass unit then it should only be wired with a fail safe lock and in series with the
lock. The maximum acceptable resistance for all of these connections = 3Ω (ohms) or less for best possible
performance. Table A below shows the recommended cable type to use*1.
Power Supply, Lock Release, Push to Exit and Break Glass Connections
Table A
Connection 20m 30m (max.)
Art.521 Power Supply 2 core YY @ 0.5mm² 2 core YY @ 0.75mm²
Lock Release 2 core YY @ 0.5mm² 2 core YY @ 0.75mm²
Push to Exit 2 core YY @ 0.5mm² 2 core YY @ 0.75mm²
Break Glass 2 core YY @ 0.5mm² 2 core YY @ 0.75mm²
(*1 Please Note: It is perfectly acceptable to use an equivalent cable type if a 2 core YY cable is not being used
providing it meets the same cable characteristics as those described above and those shown in table A).
Art.3171 Audiophone Connections
The Art.3171 audiophone requires a 2 core databus connection (L and -) with a maximum acceptable
resistance of 7.5Ω (ohms) or less. For the databus connections a twisted pair cable should be used. Doubling
up on these connections to increase the CSA (cross sectional area) of the connection and reduce the
overall resistance is acceptable, however it should be noted that wherever possible no more than 2 cores
per connection should be used as this can cause an increase in capacitance of the cable. The maximum
acceptable resistance for all of these connections = 7.5Ω (ohms) or less for best possible performance. Table
B below shows the recommended cable type to use*2 and the cable distance shown is the overall cable run
between the intercom door panel via the central point, where the power supply (Art.521) is located, up to
and including where the Art.3171 audiophone is located. If more than one intercom door panel is used on
the system (multiple entrance system) then an additional core for the BSY (busy) connection will be required,
but will only need to be connected between the central point and the intercom door panels being used.
IMPORTANT NOTE: Please be aware that when selecting a cable for this audio kit the following should NOT
be used: Copper Coated Steel (CCS) and Copper Clad Aluminium (CCA). While these types of cable may oer
a low cost solution they will have a higher resistance than pure copper cable and can aect the overall
performance of the system therefore Videx DO NOT recommend these types of cable.

PANEL AND BACK BOX INSTALLATION
The following guide lines should be followed with respect to the installation and care of the VR panel and
accompanying back box. The back box should be adequately secured to the wall to prevent risk of injury.
• To prevent water ingress to the VR120 panel ensure that a good seal between the back box and the face
plate itself is made. The neoprene seal on the face plate will oer this as long as the back box front is ush
with the wall surface. Always ensure the panel is tightened suciently to compress the neoprene seal.
• In the event of gaps due to uneven walls we suggest a silicon sealant be used. In the event of water
ingress to the back box we would also suggest drilling 3x4mm holes at the bottom of the back box to
allow any collection of water to escape.
• Always ensure all cable entry points are suciently sealed to prevent water ingress (refer to Fig.5, Fig.6
and Fig.7 respectively). All cables should loop down and then back up to the termination connections to
avoid any water travelling along the cable and onto the pcb.
The VR intercom door panel must be earthed to its back box (with the earth strap provided) and then the back
box earthed to the buildings earth connection.

Back Box Mounting Height
A suitable height to mount the back box (from oor
level up to the top edge of the back box) is anywhere
between 160 - 170cm, as shown in Fig.8, (it should
be noted, however, consideration should be taken
into account to mount the back box based on user
specic requirements). The intercom cables can be
fed through any of the available 20mm knockouts at
the rear of the back box and should be given enough
‘slack’ to enable the cable wires to be connected to
the panel components.
VR Panel Mounting
After the back box has been tted the VR panel can
then be xed into position using the hex pin security
screws provided and using a ‘torx’ screwdriver, as
shown in Fig.9.

PANEL CARE AND MAINTENANCE
The VR intercom door panel is manufactured from brushed 12 Gauge 304 grade stainless steel. It is important
that the fascia is cleaned on regular occasions to prevent dirt build up and tarnishing of the metal. A general
household metal polish can be used but care should be taken to follow the grain of the metal when polishing
and always only polish in one direction with a soft cloth to avoid light scratching of the fascia. Also try to
avoid any polish build up around the call button which may prevent the button from operating correctly.
Table C below identies the best methods for cleaning and maintaining the intercom door panel.
Table C
To Clean Method
Finger Prints Detergent and warm water or a household polish.
Routine Cleaning Soap, detergent or dilute (1%) ammonia solution in warm water.
Staining and
discolouration
Mild non-scratching creams and polishes. Take care to avoid build up of creams in
the buttons which could cause sticking.
Cleaners that CANNOT be used
• Chloride containing cleaners.
• Hydrochloric acid based cleaners.
• Sidol stainless steel cleaner (can aect engraving).
• Hydrochloride bleaches.
• Silver cleaners.

138N wire harness is rmly plugged in between the UIM-138 display module
and the 138N speaker.
Check that the 138N speaker has 12Vdc connected, if necessary check the dc
psu has a steady 12Vdc output.
Check that the contrast control on the UIM-138 display module hasn’t been
turned down. Try adjusting the contrast control until the display shows the
programmed message (refer to page 11).
If there is still nothing shown on the UIM-138 display module try performing a
module reset (described on page 35).
No speech annunciation
coming through the 138N
speaker amp.
Check that the volume control on the UIM-138 display module hasn’t been
turned down. Try adjusting the volume control until there is speech playback
(refer to page 9).
Check that the volume and balance POTs on the back of the 138N speaker
haven’t been turned down. Try adjusting the volume and balance POTs on the
back of the 138N speaker amp until there is speech playback.
Check the speech playback setting hasn’t been switched o via the programmer
software on the ‘settings’ window (refer to pages 16 - 17).
The auxiliary inputs on
the UIM-138 display
module aren’t performing
as expected.
Using the programmer software check that the auxiliary inputs have been
setup correctly according to the users requirements (refer to pages 17 - 18 for
the auxiliary input modes).
Check the wiring between the auxiliary inputs and the push buttons or the
devices they are connected to are not damaged in any way (this will also depend
on the users requirements).

Symptom Tests / Checks to carry out
Intercom panel display
switches between ‘ERROR’
and ‘PRESS BUTTON
TO CALL’ and makes an
acoustic signal every few
seconds.
Check the polarity of the L/- BUS connections between the Art.138 speaker
and the Art.3171 audiophone.
Check the L/- BUS voltage (should be 7.5Vdc at the intercom panel and at the
audiophone).
If necessary reset the Art.138N speaker as a ‘MASTER’ panel (refer to dip-switch
settings on page 8).
When the call button is
pressed the intercom
panel is not able to ring
the audiophone. The

(refer to phone ID dip switch setting on page 13).
Check that the yellow and white wires from the Art.138N speaker wiring
harness are connected correctly to the DDA call button (refer to page 8).
The Intercom panel
makes a call correctly and
the audiophone rings,
but when answered the
communication is cut
OFF.
Check the L/- BUS voltage (should be 7.5Vdc at the intercom panel and at the
audiophone).
Increase the CSA of the L/- BUS connection by doubling up on the cable cores.
The call rings through
to the audiophone okay,
but there is only one-way
speech.
Check the input voltage to the Art.138N speaker hasn’t dropped below 10.5Vdc.
Check the GND and +12Vdc connections on the Art.521 PSU and on panel the
Art.138N speaker, also check the voltage output on the PSU with and without
load.
