MANUAL INTRODUCTION
The information in this manual is intended as an installation and commissioning guide for
the vandal resistant one button audio intercom kit. This manual should be read carefully
before the installation commences. Any damage caused to the equipment due to faulty
installations where the information in this manual has not been followed is not the
responsibility of Videx Security Ltd.
VIDEX run free training courses for engineers who are not familiar with the Videx product
range. Technical help is also available on 0191 224 3174 during office hours or via e-mail
tech@videx-security.com.
SYSTEM INTRODUCTION
This kit will enable a caller at an entrance point to signal an occupant in the dwelling by
pressing a call button which will send an electronic call tone to an audio telephone. A
Yellow ‘SPEAK’ LED will indicate the call has been answered and a two way conversation
can take place, the occupant can release an electric lock release by pressing a button on
the telephone base unit. The kit does not include the electric lock release. A 12V AC
release should be used with this kit (The output for the lock is a dry contact relay so any
other type of lock can be used with an appropriate PSU). If this kit is to be used with a
gate, the dry contact output can be used to trigger the gate control board. DDA features
such as a ‘SPEAK’ LED, ‘DOOR OPEN’ LED and reassurance tones are standard on this
kit.
SYSTEM COMPONENTS
This kit comprises of a flush or surface vandal resistant door panel, audio telephone and
PSU. Up to a maximum of three telephones can be used on the system to call in parallel.
DOOR PANEL
The vandal resistant door panel will consist of an amplifier module, button, vandal resistant
plate, frame and back box.

POWER SUPPLY
Art.520M
The power supply is the Art.520M. Outputs of 12Vdc (200mA), 8Vdc (300mA) and 13Vac
(1A) are available. The dc outputs are designed to power the amplifier modules only and
must not be used to power other devices such as lock releases etc. These items must be
connected to the AC output of this power supply or an auxiliary power supply.

Art.3111
BLOCK DIAGRAM
INSTALLATION
The wiring diagram towards the back of this manual should be followed carefully. Heavy
duty conductors on wiring diagrams are shown heavily outlined, these wires should be
doubled up.
- Check that all components are free from damage before installing (Do not proceed with installation in the
event of damage).
- Keep all packaging away from children.
- Do not obstruct the ventilation openings or slots on any of the devices.
- All connections to mains voltages must be made to the current national standards (IEE Wiring
regulations)
- Install an appropriate fused spur or isolation switch to isolate the mains.
- Isolate the mains before carrying out any maintenance work on the system.
- All intercom and access control cables must be routed separately from the mains.
- When the panel is mounted on an uneven surface, use additional sealant to protect from water ingress.
LOCK RELEASE
12V AC
~~ 0.1uF capacitor
The Art.3111 is a white ABS plastic wall mounting electronic call
telephone and includes a lock release push button and spare dry
contact button. There is a three position call volume control external
to the top left side of the telephone.
CONNECTIONS:-
Function
1 Transmit speech to the door panel
2 Receive speech from the door panel
3 0V
4 Call tone input
5 Lock trigger (Switched 0V)
6 Not used
8 One side of spare dry contact button (Max. 200mA 24V)
9 Second side of spare dry contact button (Max. 200mA 24V)
Lock release back EMF protection : A
capacitor should be fitted across the terminals on
an AC lock release as shown in the diagram
below to suppress back EMF voltages.

Connections 0.5mm² 0.75mm²
The power supply should be located as close to the door panel as possible for best performance.
Maximum acceptable resistance for above cables = 3Ω
TESTING THE INSTALLATION
- Check all the connections have been made correctly and dip-switches have been set
and then power up the system.
- Call the apartments. Check for call to the apartment, speech in both directions and lock
release and correct operation of the SPEAK & DOOR OPEN LED’s.
- If the volume of speech needs to be adjusted, this can be done by adjusting the presets
on the rear of the amplifier at the door panel.
PANEL CARE
The door panel is manufactured from 12 Gauge 304 grade stainless steel. It is important
that the facia 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 also avoid any polish build up around the call
button which may prevent the button from operating correctly.

WIRING DIAGRAM
o A normally open push to exit button can be connected across PTE & - on the door
panel.
o When triggering a gate, use C & NO as dry contacts.
o When using a fail safe lock release use a separate DC PSU and the NC connection
instead of the NO connection.
o Remember to fit the 0.1uF capacitor across the lock release.

TROUBLE SHOOTING
SYMPTOM TEST
No speech from the door panel to the
telephone.
Check terminal 2 on the amplifier for continuity to
terminal 2 on the telephone.
Check the voltage drops to approx. 1Vdc after the
handset is lifted. (If not try another telephone)
If all else fails try another amplifier at the door station
No speech from the telephone to the door
panel.
Check terminal 1 on the door panel amplifier for
continuity back to terminal 1 on the telephone.
Check the voltage drops to approx. 4Vdc after the
handset is lifted. (If not try another telephone)
If all else fails try another amplifier at the door station
No speech in either direction Check the 315mA fuse in the power supply
Check for 12Vdc across terminals + & - on the door
panel amplifier. This should be there all the time and
comes directly from the PSU.
Lock will not operate from telephone Check terminal 5 on the telephone. This terminal
shorts to terminal 3 of the telephone when pressed
(Becomes 0V) and sends a 0V to terminal 5 on the
VX136 amplifier at the door panel which in turn
triggers the relay
Check the relay on the VX136 is energising. Use a
continuity meter to check the switching.
Nothing happens when call button is
pressed
Check the common of the button is connected to T
on the VX136
Check continuity from the other side of the call
button to terminal 4 on the handset
Hum on the speech lines Ensure all intercom cables do not run close to higher
voltage cables
Try another amplifier at the door panel.
