VLS-AIM INTERFACE MODULE

MANUAL INTRODUCTION

The information is this manual is intended as an installation guide for the Videx intercom to
SmartDisc/SmartTel digital video transmission system. 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 Vista.
SYSTEM INTRODUCTION

The VLS-AIM module has been designed to interface a standard Videx door panel with the Vista
SmartDisc/SmartTel Digtial video transmission system to allow a call to be made from the Videx door panel.
Both duplex speech and video are supported by the system and a facility to release a lock is also available.
For more information please consult the SmartDisc/SmartTel manual.
SYSTEM COMPONENTS

The VLS-AIM will interface with any of the following Videx door amplifiers (For convenience they are shown
with camera and back box as sets):-

DOOR PANELS
The door panel connections are as follows:-
Connection Function
Speech volume adjustments are carried out at the door panel using a small trimmer driver.

AUDIO SYSTEM POWER SUPPLY

The Art521 is a 12Vdc power supply with a 800mA continuous or 1A surge output.
CONNECTIONS
Terminal Function
+12

VIDEO POWER SUPPLY
Art. 893N
20Vdc 800mA continuous 1A surge PSU. This power supply only
has an output when either a 0V is applied to –C or when a voltage
is applied to +C. At all other times the + output is switched off.

Connection Function
230V~ 0
Switched 20Vdc output (Triggered by –C or +C) + volts trigger input (From 8V up to 30V)
SYSTEM OPERATION
When a call is placed from the door panel a signal is sent to the SmartDisc/SmartTel alarm
input. The SmartDisc/SmartTel operator must then activate relay 1 to open the speech and
video paths to the door panel. The SmartDisc/SmartTel operator can then activate relay 2
to release the door if required. Please consult the SmartDisc/SmartTel manual for more
information.
INSTALLATION
The wiring diagrams 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.

VLS-AIM TECHNICAL MANUAL
- Check that all components are free from damage before installing (Do not proceed with - 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 - 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 protection : A diode must be fitted across the terminals on the lock release
to suppress back EMF voltages. The diagram below shows the polarity of the diode when
fitted to the release.
LOCK RELEASE

Cable size and type : When running cables for any intercom system, these cables must
be installed separately from the mains cables. All multi pair cables should be to CW1308
specification. (0.5mm twisted pair telephone cable). Max resistance = 10 Ohm.
Lock release wires should be doubled up. Max resistance = 3 Ohm
The cables 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.
