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

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 buzz an audio telephone inside. A two way conversation
can take place once the telephone is answered and then if required, the occupant can
release an electric lock release by pressing a button on the telephone. Additionally users
can gain access using an access code. The kit does not include the electric lock release. A
12V AC release should be used with this kit.
SYSTEM COMPONENTS
This kit comprises of a flush vandal resistant door panel with coded access, audio
telephone and PSU. The door panel can be converted to surface by ordering the VR/S2
surface back box. 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, codelock module,
button, vandal resistant plate and back box.

Speech volume adjustments are carried out at the door panel using a small trimmer driver.
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
can 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.

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.
Lock release and AC buzzer back EMF protection : A capacitor must be fitted across
the terminals on an AC lock release and the AC buzzer inside the telephone. When using
a DC lock release with a separate DC PSU a diode must be fitted across the terminals of
the lock release as shown in the diagrams 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 then power up the system.
- Call the apartment. Check for call to the apartment, speech in both directions and lock
release.
- 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 panels are manufactured from either 12 Gauge 304 grade stainless steel or
mirror finished brass. 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.

VX800N CODELOCK
The VX800N includes two relays (5A contacts), two push to exit inputs (Switched negative)
and can have up to two 4 to 8 digit access codes programmed (One per relay). The relay
times can be programmed from 01 second up to 99 seconds or by setting the relay time to
00, latch the relay(To latch, enter the code followed by enter and to unlatch enter the code
followed by clear).
INITIAL PROGRAMMING
All programming is carried out using the codelock keypad. The programming menu is
protected by an engineer’s code. The factory default engineers code is 111111 (6x1). This
code can be changed to any four to six digit code during the program but must be different
to the codes used to gain entry. Follow the flow chart to setup the system:-
Enter the master code.
111111
Then press enter
The red LED will illuminate to acknowledge programming mode. If the red
LED does not illuminate check the master code is correct. If the master
code may have been changed from the factory default and you do not
know what it is then follow the factory default procedure on the following
page.
Enter a new engineers
code or enter the same
engineers code again
followed b
y
enter
This code can be from 4 – 8 digits and will not activate a relay. It can only
be used to enter programming mode.
Note this new code in the box provided on the next page. It will be needed
to re-program the codes in the future.
Enter the access code
for relay 1 and then
press enter
This code will be used to open the door/gate (Relay 1). The code can be
from 4 – 8 digits long and must be different from the engineer’s code.
Enter a two digit relay 1
time from 00 – 99 and
then press enter
This is the time the relay 1 will energise for. 00 will latch the relay when
the code is entered and require the code followed by clear to unlatch.
Enter the access code
for relay 2 and then
press enter
This code will be used to open the door/gate (Relay 2). The code can be
from 4 – 8 digits long and must be different from the engineer’s code.
Enter a two digit relay 2
time from 00 – 99 and
then press enter
This is the time the relay 2 will energise for. 00 will latch the relay when
the code is entered and require the code followed by clear to unlatch.
More
codes?
YES
NO
Press enter twice The red LED will go off to confirm the exit from programming mode.
