A copy of this Technical Manual can also be downloaded from the Videx websites: For UK customers www.videxuk.com and for
overseas customers www.videx.it.

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 50 call buttons can be connected to the door panel, each able to
call four telephone numbers (if the rst is busy or not answered, the call can be diverted to up to three dierent numbers). The
standard GSM PRO intercom works on a 2G network. A 3G variant is also available (sux /3G to the part number e.g. Art.4810-0/3G,
Art.4810-1/3G etc.). Features of the system include:

• A dry contact relay output and push to exit input;

• Two open collector auxiliary outputs and two auxiliary inputs;

• Integrated Proximity Access Control (up to 1000 proximity fobs or cards can be stored, these fobs/cards when presented to
the nameplate window on the GSM PRO intercom or directly in front of the Art.4850R expansion reader will activate the
door/gate relay);

• Call progress speech annunciation and call progress LED indication;

• Dial to Open facility (this feature enables up to 1000 stored numbers to dial the GSM PRO intercom, the intercom panel will
not answer these calls, but will activate the door/gate relay without being charged for the call);

• Programmable call button timeband facility (a single timeband only);

• Programmable access control timeband facility (up to 10 timebands);

• Programmable free access timeband facility (up to 10 timebands);

• Up to 10 programmable access levels;

• Micro USB connection for ease of programming using the GSMSK PC software (version 4.0.0.0 or later);

• RS485 bus terminals for connecting additional ‘slave’ devices including coded keypads (Art.4903) and additional proximity
readers (Art.4850R), up to a maximum of 8 devices, also used for ease of programming using the GSMSK PC software;

• Integrated bootloader function for updating intercom panel rmware via the GSMSK PC software;

• Event logging system that can record up to 4000 events which can be downloaded via the GSMSK PC software;

• Remote event logging facility (unlimited events) which can be monitored in real time (also refer to additional notes on page
71 under user management).

Programming of the telephone numbers (primary no, divert no’s and dial to open no’s) and the additional features including
programming key fobs for the integrated proximity reader and additional proximity readers, programming access codes for
additional coded keypads, timebands, access levels etc. can be carried out via text messaging (refer to notes programming the
GSM intercom on pages 37 - 61) or using the GSMSK PC software (refer to the manual GSMSK_66251720_EN_V2-0 or later).

SIM CARD SELECTION

A SIM card is required for this product but not supplied by Videx. The GSM PRO intercom can only accept a standard size SIM card
(refer to the following SIM card size chart), both a micro-SIM and nano-SIM are not suitable. 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, however if using a ‘Pay as you go’ we would recommend setting up an automatic top up to avoid running short
on credit and losing 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 website.

NETWORK PROVIDER SELECTION

It is imperative that for the reliable 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.

For UK customers, as an initial check we also recommend visiting the ofcom website www.ofcom.org.uk and follow the onsite links to
their online mobile coverage tool (ofcom broadband and mobile checker app). This tool will advise on the best coverage for the main
network providers and other general queries that you may have about the service provider. For all overseas customers we suggest
consulting the website of the network provider that will be used to check the coverage in your area.

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 aect 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. This
number is located internally on the main hardware chip inside the GSM PRO module. To obtain the IMEI number from the GSM
module refer to the programming notes obtain the GSM’s IMEI number on page 61.

PRECAUTIONARY ADVICE

• 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 ensure the power is switched OFF to the intercom panel before inserting or removing the SIM card.

• New SIM cards will need registering with the network service provider 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. Recommended SIM card providers are: Vodafone, T-Mobile, O2 or
Orange/EE. The 3 network can only be used on our 3G devices (Art.4810-0/3G, Art.4810-1/3G etc.), also refer to page 6.

• 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 conrm this by
inserting the SIM card into a mobile phone and using the phones menu options to check it. If a number is not programmed then
it should be programmed while in the phone (the number can be obtained from the network service provider).

• 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/EE, T-Mobile and other providers the
SIM card must be removed from the intercom panel, inserted into a mobile phone and the mobile phone menu instructions
followed. This procedure may vary from provider to provider of dierent countires, we suggest contacting your provider for
information.

• 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.

• 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.

• This product may not be suitable for installation in hospitals, health care facilities or in the presence of ammable gases or
liquids. Seek advice and authorisation before installing this product in these locations. This product is not designed to be used

as an emergency call point.

Network provider and services conguration codes mentioned in this manual are specic for the UK. For overseas customers please contact
the network provider of your country for the corresponding codes, however Videx oers no guarantee that any additional codes will work.

IMPORTANT NOTE ABOUT THE SIM

When using a pay monthly SIM card you can ask the service provider to put a spend limit (credit 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. Most network providers oer this service. You will need to either ring or e-mail them to set this up. Automatic top
ups should also have a monthly limit. We would suggest a limit of £50.00 which should be more than enough. This service is not

provided by Videx.

Button connections to the GSM module are shown in Fig.4 on page 7 (only the wiring of the button matrix is shown). It is important
to take care when using additional button modules with a GSM intercom module which also has onboard buttons. For example, an
intercom module with one button means the extension button module used must start wiring from button 2, an intercom module
with 2 buttons means the extension button module used must start wiring from button 3 and so on.

IMPORTANT NOTE: When extension button modules are being used
on systems where proximity access is required and the Art.4810-0 GSM
PRO module is used, the location of the onboard proximity reader is on
the front of the main GSM PRO module below the speaker, as shown in

Fig.3.

Standard versions of the GSM PRO (e.g. Art.4810-0 etc.) works on a 2G
network. A 3G variant is also available (see Fig.1 above) that works on a
3G network, sux /3G to the part no. (e.g. Art.4810-1/3G etc.).

RS485 BUS TERMINATION JUMPER JP1

The jumper JP1 on the rear of the keypad sets the RS485 bus termination when
connected to the Art.4810 GSM PRO or other RS485 devices. By default the
jumper is set to the ON position (across to the left). When more than one RS485
device is connected to the keypad in line on the RS485 bus terminals then the
jumper can be set to the OFF position (across to the right) and only set to the

ON (closed) position on the end of line device, see Fig.12.
RELAY BUILTIN BACK EMF PROTECTION JP2 AND JP3

The Art.4903 includes selectable back EMF protection (metal oxide varistors)
jumpers JP2 and JP3 for each relay (marked MOV) and are used to select the
protection type. When using a fail secure lock with connections C & NO the
jumper should be in the NO position. When using a fail open (safe) lock with
connections C & NC the jumper should be in the NC position, as shown in
Fig.13. When using the codelock to trigger a gate controller or another third
party controller the jumper should be removed completely (this disables the
protection on the relay).

PROGRAMMING AS A STANDALONE KEYPAD

When using the Art.4903 as a standalone keypad the programming is the same as the programming of an Art.4800M keypad
(refer to programming guide and owchart below). All programming is carried out using the keypad. The programming menu is
protected by an ENGINEER’S CODE, the factory default of which is six times 1 (“111111”). This code can be changed to any 4 to 8
digit ENGINEER’S CODE during the programming and is used to gain entry to the programming menu only.

Each relay (RLY1 and RLY2) can be programmed with a 4 - 8 digit access code (one code per relay) and will activate the respective
relay for the programmed relay time (01 - 99 seconds or 00 for latching). The access code programmed is stored in the keypads
internal memory.

PROGRAMMING WHEN INTEGRATED WITH THE GSM PRO ART.4810 MODULE VIA THE RS485 BUS CONNECTIONS

The Art.4903 can also be programmed using the GSMSK PC software
(refer to the manual: GSMSK_66251720_EN_V2-0 or later) and also
via text messaging (refer to notes programming the GSM intercom on
pages 37 - 61). When wired directly to the GSM PRO module using the
RS485 bus connections, see Fig.16, additional access code features of
the GSM PRO module become available which include:

• program up to 400 permanent access codes (000 - 399);

• assign any of the 400 access codes to an access level (0 - 9) and relay;

• program up to 32 temporary access codes;

• allocate any of the 32 temporary codes to a specic time period

(between 1 - 255 hours) after which time the code will be deleted;

• assign any of the codes, whether permanent or temporary, to trigger

any or a combination of the two relays (RLY1 and/or RLY2).

Also refer to notes RS485 network connection on pages 27 - 29.

The access codes can be 4 - 8 digits in length and are stored in the GSM
PRO module’s memory not the keypad.

Even when the Art.4903 is connected to the GSM PRO with the RS485 bus
connection any access codes programmed directly using the keypad,
following the programming owchart on page 15, for relays 1 and 2 (as if
the keypad were programmed as a standalone keypad) will still operate
the respective relay.

The RS485 connection also allows the keypad to be networked with other
Art.4903 keypads and Art.4850R proximity readers where each module
requires a unit ID to be setup (see below) up to a total of 8 devices.

DESCRIPTION LEGEND

The Art.4850R proximity reader is an expansion reader that can be connected to
the Art.4810 GSM PRO intercom via an RS485 bus connection. It allows the GSM
intercom to have up to 7 additional proximity access doors or can be used with
a combination of proximity and coded access using the Art.4903 keypad (up to
a total of 8 devices with the GSM PRO’s onboard reader as device ID.1).

The front of the module has a tri-colour LED to indicate to the user the status of
the reader (amber = standby, green = access granted and red = access denied).
The reader is housed in a 4000 series module with a stainless steel or aluminium
surround front frame, see Fig.17.

When connected directly to the GSM PRO intercom module with the RS485 bus
connection it can be programmed by either sending SMS text messages (refer
to notes programming the GSM intercom on pages 37 - 61) or using the GSMSK
PC software (refer to the manual: GSMSK_66251720_EN_V2-0 or later).

setting the unit ID on page 18).

IMPORTANT NOTE: The Art.4850R reader can only be used as an expansion reader for the GSM PRO intercom, therefore
programming can only be carried out (when connected by RS485) by sending SMS text messages to the GSM PRO or using the
GSMSK PC software (software version 4.0.0.0 or later). The only manual programming that can be performed on the module is
the unit ID setup and relay time. All proximity fob data is actually stored in the GSM module’s memory and not the proximity
reader.

Compatible key fobs: 955/T and/or PBX-1E ; compatible proximity cards: 955/C and/or PBX-2.

IMPORTANT NOTE: MIFARE PROXIMITY FOBS/CARDS CANNOT BE USED WITH THIS READER.

CONNECTING TO A GATE CONTROLLER

For a GSM4K series audio kit if the Art.4810 GSM intercom is going to be connected to an electric gate then the wires from the gate
controls can be connected directly into the C and NO relay terminals on the GSM module, as shown in Fig.27. For a GSM4KCR series
audio kit if the gate controls are going to be connected directly to the Art.4903 keypad the relay terminals C1 and NO1 can be used
(or C2/NO2 depending on the relay required), remembering to remove the respective back EMF protection jumper (JP2 or JP3), as
shown in Fig.28.

CONNECTING A PUSH TO EXIT BUTTON AND A BREAK GLASS UNIT

The push to exit button must be congured as a “push-to-make” switch and connected across terminals g & 6 on the Art.4810 GSM
PRO module. The break glass unit, congured as a “push-to-break”, would only be used when connecting a fail safe/fail open lock
release (e.g. a mag lock) and would connect in series with the GSM’s relay connections C and NC, as shown in Fig.29.

When the exit button is pressed the GSM relay will trigger for the programmed relay time. When the break glass unit is activated it
will break the power to the mag lock.

Auxiliary Inputs/Outputs

AUXILIARY OUTPUT AO1

The auxiliary output AO1 has six modes 00 - 05 and is set using the A1M command (refer to page 43 for full list of A1M programming
modes). It is an open collector output (switched low, 150mA max.) and depending on the mode it is set to will determine how the
AO1 output behaves. The following examples show how the AO1 output can be connected.

AO1 SET TO MODE 00, ‘CALL ACTIVATED’

When set to mode 00 auxiliary output AO1 will activate when the call begins and deactivate when the call ends, as shown in Fig.30.

To Antenna

Art.4810

AO1 output will activate
for the duration of the call

Fig. 30

AO1 SET TO MODE 01, ‘USER ACTIVATED’

When set to mode 01 auxiliary output AO1 will activate when the terminals g & 5 are shorted together on the GSM PRO module or
by pressing 6 on the telephone during a call, as shown in Fig.31. Auxiliary output AO1 will only activate for the programmed time.

Auxiliary Inputs/Outputs

AO1 SET TO MODE 02, ‘STATUS INDICATION’

When set to mode 02 auxiliary output AO1 is used exclusively as a monitoring input. For example, checking if a gate/door is open
or closed. Once set the AO1 input status can be interrorgated in two ways:

1. During a call: press 9 on the telephone keypad and listen to the number of beeps in the ear piece. One beep indicates the input
is closed and two beeps indicates the input is open.

2. At anytime: send the SMS message 1111CHK? to the GSM PRO intercom. An SMS message will be returned with IN=OP for
open or with IN=CL for closed.

For this feature an additional relay will be required and the AO1 input must be wired as shown in Fig.32.

AO1 SET TO MODE 03, ‘DIVERT CALLS TO MASTER NUMBER’

It is possible to have the GSM PRO call buttons diverted to the master number (outside certain hours) using the TBA timeband
feature (refer to timeband TBA programming notes on page 47). Alternatively it is possible to divert the GSM PRO call buttons to
the master number when auxiliary output AO1 has been set to mode 03 (auxiliary output AO1 is used as a monitoring input). In
this instance a switched common and normally open (CO/NO) trigger needs to be used to enable or disable ‘divert calls to master
number’ and the auxiliary output AO1 must be wired as shown in Fig.33. In either case a master number is required following the
STM store master number feature (refer to STM programming notes on page 46).

If there is no master number stored, the intercom will beep and the busy LED will ash once to indicate no call is taking place (if the
speech board is switched ON, the GSM PRO module will announce “the phone is switched o please try later”).

AO1 SET TO MODE 04, ‘CALL ACTIVATED TIMED’

Similar to mode 00, however, when set to mode 04 auxiliary output AO1 will activate when the call begins and deactivate when the
auxiliary AO1 time expires, see Fig.34.

The auxiliary output AO1 time can be set using the SMS programming code 1111A1Tnn? (where nn = time in seconds, also refer to
notes programming the GSM intercom on pages 37 - 61) or setup by using the GSMSK PC programming software.

AO1 SET TO MODE 05, ‘ENABLE/DISABLE DIAL TO OPEN NUMBERS’

When the auxiliary output AO1 mode is set to 05 the dial to open numbers will only activate the GSM relay when a common and
normally open (CO/NO) switch connected across terminals g & AO1, as shown in Fig.35, is open circuit. When the switch is closed
and terminals g & AO1 are short together this will disable the dial to open numbers.

To Antenna

Art.4810

IMPORTANT NOTE: When auxiliary output AO1 is set to a particular mode (00 - 05) it cannot be used as an input/output for
anything else.
