Introduction

MANUAL INTRODUCTION

The information in this manual is intended as an installation and commissioning guide for the 4000 series GSM LITE audio intercom
system. This manual should be read carefully before the installation commences. Any damage caused to the equipment due to faulty
installation where the information in this manual has not been followed is not the responsibility of Videx Security Ltd.

It is recommended that the GSM audio intercom is installed by a competent electrician, security or communications engineer.

For UK customers Videx run free training courses for engineers who are unfamiliar or who have not installed this system before.
Technical help is also available for UK customers on tel: [phone] during oce hours (8:30am - 5:00pm MON to FRI) or via e-mail:
[e-mail] and for all overseas customers on tel: [phone] or via e-mail: [e-mail].

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 4 call buttons are available in the door panel, each able to call two
telephone numbers a primary number and a divert number (if the rst is busy or not answered, the call can be diverted to a second
number). The standard GSM LITE intercom works on a 2G network. A 3G variant is also available (sux /3G to the part number e.g.
Art.4811-1/3G, Art.4811-2/3G etc.). Features of the system include:

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

• A single open collector auxiliary output (AO1) and two auxiliary inputs;

• Dial to Open facility (this feature enables up to 100 stored numbers to dial the GSM LITE intercom, the intercom panel will
not answer these calls, but will activate the door/gate relay without being charged for the call);

• Program both primary and divert number in a single text message;

• Program up to 5 dial to open (DTO) numbers in a single text;

• Delete a dial to open (DTO) number without knowing it’s stored location;

• Up to 5 possible auxiliary output modes (AOM);

• Programming carried out via SMS text messages or limited programming features using the GSM mobile app, the Videx
SMS Wizard.

SIM CARD SELECTION

A SIM card is required for this product but not supplied by Videx. The GSM Lite intercom can only accept a standard size SIM card
(refer to the following SIM card size chart below), 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, as this service is not provided by Videx.

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.

4000 Series GSM Lite Audio Intercom

Introduction

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 LITE module. To obtain the IMEI number from the GSM
module refer to the programming notes obtain the GSM’s IMEI number on page 39.

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 website 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.4811-1/3G, Art.4811-2/3G 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 pre-installed 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.

When using a fail secure lock with connections C & NO the jumper should be in
the NO position for the selected relay (RLY1, RLY3 or RLY3).

When using a fail open (safe) lock with connections C & NC the jumper should
be in the NC position for the selected relay (RLY1, RLY3 or RLY3).

When using the codelock to trigger a gate controller or another third party
controller the respective jumper should be removed completely (this disables
the protection on the relay), as shown in Fig.10

PROGRAMMING THE KEYPAD

All programming is carried out using the keypad. The programming menu is protected by an ENGINEER’S CODE, the factory default
of which is 6x1 (“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, RLY2 and RLY3) 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.

BACK LIGHT AND BUTTON OPERATION

If the back light programming mode is set to mode 1 (with jumper JPL in either the A or B position) when a button is pressed on the
keypad the back light will switch to full brightness for approximately 10 seconds.

After this time the back light will either switch OFF or switch back to low brightness (depending on the jumper position) unless
another button has been pressed within the 10 second period in which case the back light will stay on full brightness for a further
10 seconds.

The exception to this is if the back light programming mode is set to mode 2, i.e. the back light will be on full brightness all of the
time or if the jumper is removed the back light will be disabled.

OPERATION

• Type in the programmed access code and press ENTER to conrm;

• If the access code is correct, the green accept LED (Fig.9,

) will illuminate for approx. 2 seconds and the relay that is relevant to

the code will operate for the programmed relay time;

• If an incorrect access code is entered, a continuous melody will sound for 4 or more seconds, according to the number of mistakes

and the red program/error LED (Fig.9,

) will illuminate.

OPERATION NOTES

• To operate the relays together, set the same code for each relay;

• If an incorrect code is entered, the system will lock out for 5 seconds which will increase each time an incorrect code is entered.
The system will only operate when the correct code is entered.

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.4811 GSM
LITE 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.14.

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.
