INSTALLATION DIRECTIONS

For video door entry systems that user colour monitors, we recommend to use a coax cable.

All the operations of installation and maintenance must be carried out by specialized engineers only. Do not

install the components of the system in humid environments or near heat sources. Make sure that the power

supplies present in the system are not connected to the mains, during the mounting operations of the

devices. Before powering the system, check that the cabling is correct and that the voltage levels are

compatible with other power suppliers on the system. The wiring diagrams must always be followed (in case

of different applications contact Videx technical) and always use cables with sections as per the following

table. If the sections proposed are not respected the system may not work correctly. It is advisable to

separate the Mains lines (lift, electricity, electricity lock, etc.) from the BUS lines (A distance of at least 10

cm) to avoid electrostatic discharge and magnetic influence that could cause control problems to the CPUs

present on the system.

Supply cables ( power supply Æ outdoor station): they must have a minimum size of 1.0mmsq (AWG17)

of 1.5 Ohm

for each wire.

Features of the system

For intercom systems the upright column consists of the “2 wire” BUS, while for video intercom systems it is

necessary to install a minimum of the “6 wire” BUS (2 wires + 2 wire bus for the balanced video signal + 2

wires for videophone power supply.

• Before switch on the system, check the cabling and set all dip-switches

• In video intercom systems it is important to connect to the output of the last video distributor Art.316 2

resistances of 75Ω ¼ W between “─” and the terminals “V1” and “V2” of the distributor or of the last video

intercom, in case of small system where Art. 316 are not used.

• All phones, videophones and accessories are identified by an address programmed through the 8 way Dip-

switch and each device must have a different address; see decimal/binary conversion table to program the

addresses. Note that each peripheral (phone, videophone or accessory) reads its address from the

dip-switch at power up (when the system is powered): to change the address of a peripheral and to

arrange that it is read again, it is necessary that the peripheral is disconnected from the system

(disconnect the BUS wires for a phone or an accessory, disconnect BUS wires and power wires for

a 900 series videophone or, for 3000 series videophones, unplug the connector from the connection

board), update the address by adjusting the dip-switch then reconnect the peripheral to the system.

• In case someone needs to activate more than one device by a single call (for example 2 intercoms in the

same apartment or 1 intercom and 1 additional sounder or 2 videophones, etc.), all devices must have the

same address up to 3 devices max. If the 3 units are videophones, to switch on at the same time another

power supply must be added, because the power supply Art.893N1 can supply a maximum 2 videophones

at the same time.

• It is necessary to check that master and slave programming of call panels are correct (VX2202, VX2203);

for the VX2203 this can be checked before powering the system (dip-switch 1 ON = Master, OFF = Slave)

while for the VX2202 the check can be done only after powering the system (the factory setup for the

VX2202 series is “MASTER”).

• The system can be on a single level (for ex. a building with 3 main entrances) or on more levels, one of

which is the main and the other are the secondary blocks. In both cases, only one of the call keypads

(VX2202 or VX2203) connected on the same level must be “master” (the master supplies the system) and

all the others must be configured as “slave”. Secondary levels are those branches of the system that are

separated from the main level by a Art.2206 or 2206V for video door entry systems.

Once the system is supplied, the programming of the VX2202 digital front panels (see the flow-chart) and of

the VX2210 concierge, if present, can be performed, paying attention that the programming of the flat

numbers (combining between the phone ID address and the call code) is the same for all the units that are

on the same level. In case of systems on more levels, the keypads of the main level and also the concierge,

if present, must contain the programming of all the phones installed in the system, while the keypads of the
