MANUAL INTRODUCTION
The information in this manual is intended as an installation and commissioning guide for
the digital GSM door intercom 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
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 office hours or via e-mail tech@videx-security.com
.
SYSTEM INTRODUCTION
The system is designed to work on the same technology as mobile phones. It enables a
call to be made from an entry point (Door, gate etc), to any telephone number (mobile or
land line). Up to 1000 apartments can be programmed into the door panel, each able to
call two telephone numbers (If the first is busy or not answered, the call can be diverted to
the second). Additionally, each user can have a unique access code up to 6 digits, an
apartment number up to 6 digits, their numbers added to the dial to open list (to allow them
to dial into the panel and release the door/gate), a time band to restrict when this
apartment can receive calls and on the scroll panels, a user name up to 16 characters.
Features of the system include a dry contact relay output, an open collector auxiliary
output, push to exit input and switched 0V auxiliary input. Programming of the telephone
numbers and additional features can be carried out via the panel, PC using a specially
designed Windows program or text message. An additional access control feature is
included for all 2000 telephone numbers allowing a number of callers to open the
gate/door simply by dialling the telephone number of the intercom panel (The intercom
panel will not answer these calls but will activate the relay output).
A SIM card is required for this product but not supplied. It is recommended to choose the
SIM card which has the best coverage for the area in which the intercom panel will be
installed. Both contract and ‘Pay as you go’ SIM cards can be used but if using a ‘Pay as
you go’ we would recommend setting up an automatic top up to avoid running short on
credit and loosing the use of the intercom panel. Alternatively if you already have a
contract mobile phone it should be possible to get a second SIM card and telephone
number on the existing account. For more information contact the SIM card provider or
visit their web sites. Remember to restrict the spend ion the SIM card to avoid
unnecessarily large phone bills due to misuse or fault.
Network provider selection: It is imperative for the reliably operation of the system that
the best network provider for the area is selected. Problems such as network
disconnection can occur if the provider has signal or interference problems for that area.
We would recommend using a GSM signal strength meter to survey the intended antenna
location. Contact Videx for more information on where to purchase a tester. As an initial
check, also go to www.sitefinder.ofcom.org.uk and enter the postcode of the intended
installation. This will show all transmitters in the area. It is advised to choose the closest
one or if there are many then choose a transmitter working on 900MHz as this frequency
works best through obstacles such as walls, buildings etc. The antenna should always be
mounted vertically at the highest point possible. Metal structures and sources of
interference such as power cables, control panels etc can affect signals and so the
antenna should be mounted away from these.

When registering a new SIM you may be asked for the IMEI number. This is the unique
serial number of the GSM intercom and can be found on the rear of the module just below
the SIM holder on a white label. It’s the long number below the barcode.

PRECAUTIONARY ADVICE
o When mounting the GSM antenna, choose a location which is away from human interaction
and away from the intercom panel. Route the GSM antenna cable from the intercom panel
so that it is separate from the power supply cables and microphone wire. Always mount the
antenna vertically.
o Always ensure the power is off to the intercom panel before inserting or removing the SIM
card.
o New SIM cards will need registering before they can be used. Full details of how this is
done can normally be found in the SIM card pack. It will normally require that the SIM card
is inserted into a mobile phone, a number dialled and instructions followed. While the SIM is
in the mobile phone it would be a good time to disable any PIN codes, call diverts, ring back
and disable features such as voicemail and text alerts. Details of how to do this can be
found on the SIM card provider’s web site or by calling their customer services. Please use
one of the following SIM card providers (Vodafone, TMobile, O2 or Orange). We do not
recommend using 3 at this present time.
o To be able to receive text messages from the intercom panel, the SIM card will require an
SMS service centre number. This is normally preinstalled on new SIM cards but if you are
having trouble receiving SMS messages you will need to confirm this by inserting the SIM
card into a telephone and using the telephones menu options to check it. If a number is not
programmed then it should be programmed while in the telephone (The number can be
obtained from the service provider).
o Voicemail and text alerts must be switched off on the SIM card when using the dial in to
release the door/gate feature. For Vodafone and O2 this can be done while the SIM card is
in the intercom panel. For Orange and T-Mobile the SIM card must be remove and put into
a mobile phone.
o When storing the intercom panel’s telephone number in your own mobile phone avoid using
an obvious name such as ‘Front Door, or ‘My Gate’ as this would make it easy to decipher if
your phone was lost or stolen.
o The PIN request feature must be disabled on the SIM card before using it in the Intercom
panel. It is likely on a new SIM card that it will not be enabled but if it is, it will prevent the
system from working at all.
o This product may not be suitable for installation in hospitals, health care facilities or in the
presence of flammable gases or liquids. Seek advice and authorisation before installing this
product in these locations.
IMPORTANT NOTE ABOUT SIM CARD
When using a pay monthly SIM card you must ask the service provider to put a spend limit
on the account (Vodafone call this service ‘spend checker’). This is to safeguard against
possible problems which could result in a large phone bill at the end of the month. All
providers offer this service. You will need to either ring them or e-mail them to set this up.
Automatic top ups should also have a monthly limit.

SYSTEM COMPONENTS
A system comprises of an intercom panel, power supply, SIM card and antenna. The
intercom panel is of modular design allowing it to be customised to the installation
requirements by including proximity access control, coded access or bioaccess.
DIGITAL MODULE
The digital panel is available for the 4000 Series modular design or flush vandal resistant.
There are two versions in the 4000 series design, name scroll facility which includes a
numeric keypad and 3 buttons to navigate tenants/company names on the display and a
alpha numeric version which includes a numeric keypad and letters A-F. The vandal
resistant panel is also available with letters A-I.
DIP SWITCH SETTINGS
There are 2 dip-switches located on the back of the module. They can be used to alter the
volume from the Door Intercom speaker. Additionally, the volume can also be adjusted
during a call via the telephone keypad.

PANEL CARE
The door panel’s facia is either mirror finish stainless steel, brushed stainless steel or matt
finish aluminium. 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 buttons which may prevent the buttons from operating
correctly.

TESTING, POWER UP AND RESET
After connecting the power supply, antenna, lock output and auxiliary devices as shown in
this manual and before powering up a SIM card must be installed. The SIM holder can be
found on the back of the module under the label ‘SIM’. A SIM card from any supplier can
be used. Simply push the SIM card in (It will only fit one way). IMPORTANT: Replace the
label over the SIM hole.
- Check all the connections have been made correctly and then power up the system.
- The GSM intercom requires approximately 30 seconds too initialise properly. We
recommend not sending SMS messages or pressing buttons during this time.
- From power up; the panel display will first show the software version number for a few
seconds and then ‘WAIT’. After a delay the display will show the standby message.
- Once initialised, you can begin programming.
RESET TO FACTORY DEFAULTS
There are two reset modes available. The first will reset the master code only and the
second will reset everything and clear all stored telephone numbers.
RESET THE MASTER CODE TO 1111
1. Power down the intercom panel
2. Hold down the ‘Enter’ button (on VR4802 or 4802) or the ‘4’ button (on 4802R)
3. Power up continuing to hold the button
