MANUAL INTRODUCTION
The informaon in this manual is intended as an installaon and commissioning guide for the Videx VR120 vandal resistant one buon audio intercom kit. This manual should be read carefully before
the installaon commences. Any damage caused to the equipment due to faulty installaons where the
informaon in this manual has not been followed is not the responsibility of Videx Security Ltd.
VIDEX run free training courses for engineers who have not installed this system before. Technical help is also available on 0191 224 3174 during oce hours or via e-mail: [e-mail].

SYSTEM INTRODUCTION
This audio kit will enable a caller at an entrance point to signal an occupant in the dwelling by pressing a call buon 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 conversaon can take place, the occupant can
release an electric lock release by pressing a buon 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, ‘BUSY’ LED, ‘DOOR OPEN’ LED and reassurance tone are standard on this kit.
A
ush back box is standard in this kit, however a ush stainless steel bezel back box and a surface
back box with rainshield are also available (see page 6).
Key Features
• 12 Gauge stainless steel.
• IP68 rated buon.
• SPEAK, BUSY and OPEN call progress LEDs.
• Call progress reassurance tone.
• Dry contact relay output for lock release or gate controller.
• Timed call, speech and lock release.
• Speaker and microphone volume adjustment.
This audio kit can be used for a single entrance system, however
it can be expanded to include mulple entrance panels.

POWER SUPPLY
The standard power supply in this kit is the Art.520M. Outputs of 12Vdc (200mA max), 8Vdc (300mA max) and 13Vac (1A max) are available. The dc outputs are designed to power the amplier module
only and cannot be used to power other devices such as code locks, lock releases etc. These items must
be connected to the AC output of this power supply.

INSTALLATION
Inial Installaon Checks
The wiring diagrams towards the back of this manual should be followed carefully. Heavy duty conductors on wiring diagrams are shown heavily outlined in some instances where voltage drop is
experienced then these wires should be doubled up.
• Check that all components are free from damage before installing (Do not proceed with the instal-
laon in the event of damage).
• Keep all packaging away from children.
• Do not obstruct the venlaon openings or slots on any of the devices.
• All connecons to mains voltages must be made to the current naonal standards (IEE Wiring regu-
laons)
• Install an appropriate fused spur or isolaon 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 Wiring and Back EMF Protecon
When ng an electric lock release back EMF protecon will be required. If ng an AC lock release then a 100nF ceramic disc capacitor must be ed across the terminals on the lock. If ng a DC
lock release (fail secure or fail safe) then a 1N4002 diode must be ed across the terminals on the lock.
CABLE TYPE AND CABLE SIZE GUIDE
The following cable types described below are measured in mm² for the cross seconal area (CSA) for each conductor (core) within the cable bundle. The tables show the distances in metres between
system components. All cable types are catagorised using the AWG (American Wire Gauge).
Suitable cables for this system are a BT type telephone cable CW1308 and a YY cable (other similar or
equivalent cables are also suitable). When selecng a parcular cable type care must be taken to ensure
that excessive voltage drop is avoided and the lowest possible resistance is achieved. Use the following
cable types and the tables as a guide to ensure that the best possible performance is achieved.
