GSM DOOR INTERCOM TECHNICAL MANUAL
VER 2.0.5
MANUAL INTRODUCTION
The information in this manual is intended as an installation and commissioning guide for
the 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 50 call buttons can be connected to 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) or with the additional divert facility enabled it is possible to have up to 10 call
buttons each with 1 primary number and 5 divert numbers. 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 text messaging or PC using a specially designed Windows
program. An additional access control feature for up to 250 telephone numbers is also
available on the system 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.
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.
PAGE 4 of 40
GSM DOOR INTERCOM TECHNICAL MANUAL
VER 2.0.5
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.
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.

STATUS INDICATION INPUT
Using the following hardware and software configuration it is possible to interrogate an
input to see if it is open or closed. This feature can be useful to find out it a gate or door is
open when it is not in line of site. The input status can be interrogated in two ways:During a call: Press 9 on the telephone keypad and listen to the number of beeps heard in
the ear piece. One beep indicates closed and 2 beeps indicates open.
At anytime: Send a SMS message 1111CHK? to the intercom panel. An SMS message
will be returned with I/P=OP for open or I/P=CL for closed.
To use this feature, auxiliary output mode must be set to 2 (Used for status indicator) and
the input must be wired as shown below:-
NOTE: WHEN USING THE AO OUTPUT FOR STATUS INDICATION IT CAN NOT BE
USED AS AN OUTPUT FOR ANYTHING ELSE.
ALL CALLS DIVERT FACILITY AND CALL BUTTONS DISABLED FACILITY
It is possible to have all call buttons diverted to the master number outside certain hours or
when an input is active. If there is no master number stored, the intercom will beep to
indicate no call is taking place. To setup the time band follow the procedure in either the
SMS programming section or the PC programming section of this manual.
To use a switch to enable or disable call divert to master number first the auxiliary output
mode setting must be set to 3 (Used to divert calls to master number) and the input must
be wired as follows:-

INSTALLATION
-
Check that all components are free from damage before installing (Do not proceed with
installation in the event of damage).
-
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
Wiring regulations)
-
Install an appropriate fused spur or isolation switch to isolate the mains.
-
Isolate the mains before carrying out any maintenance work on the system.
-
Avoid water ingress into the rear of the module, always seal the module frame after
installation using a suitable silicon based sealant.
- All intercom and access control cables must be routed separately from the mains.
Lock release back EMF protection : A capacitor must be fitted across the terminals on
an AC lock release and a diode must be fitted across the terminals on a DC lock release
as shown in the diagrams below to suppress back EMF voltages.

PANEL CARE
The door panel’s facia is either mirror finish 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.

VER 2.0.5
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; two short beeps will be heard and then following a short delay of
approximately 15 seconds, a further short beep will be heard. After approximately
another 15 seconds another short beep will be heard. The module is now fully
initialised (Note: If you here a different combination of beeps in place of the last short
single beep then you can find the meaning of these beeps towards the back of this
manual. Once initialised, you can begin programming.

PROGRAMMING
Programming can be carried out either by text message or by PC.
IMPORTANT NOTE: When you are required to use “ in a text message it is very important to use the
correct symbol and not for example ‘ (Or two ‘ single apostrophes side by side which you will see
look the same but will be interoperated differently by the SMS intercom panel).

VER 2.0.5
PROGRAMMING BY TEXT MESSAGE
Programming by text message is a simple way to customise the settings of the intercom
panel and add or delete telephone numbers. If you have a large number of buttons or
telephone numbers to enter you may find programming easier with the PC software.
Simply send texts in the format below to the telephone number of the SIM within the
intercom panel:<4 DIGIT CODE><3 DIGIT FUNCTION CODE><OPTIONAL DATA><OPTIONAL ?>
4 DIGIT CODE:
The code prevents unauthorised access to the programmable
features of the system. The code must be four digits long but
can be any combination using digits 0 – 9. The default code is
1111 and will be used for all examples in this manual.
3 DIGIT FUNCTION CODE:
The 3 digit function code identifies the programmable feature
to be changed. The code must be in capital letters. The table
below lists the available codes.

VER 2.0.5
OPTIONAL ?:
Most of the commands support the ? feature. When this is added to
the end of the text message, a confirmation text message will be sent
back to the sender indicating the new data has been received and
stored.
When sending text messages there may be a delay from when you send the message to
when it is received by the intercom panel depending on how congested the network is. If
you are at the door panel when sending the message you will here a single beep from the
intercom panel to indicate it has receive the message.
STORING THE CALL BUTTON TELEPHONE NUMBERS (STN) (STD)
Telephone numbers can be stored for the 50 available call buttons. Each call button can
call up to two telephone numbers (If the first is busy or not answered in a certain time it
can call the second number if the divert facility is setup). The STN code stores the first
number called when the button is pressed and the STD code stores the diverted telephone
number if the first is busy or not answered. The messages to store/check numbers are as
follows (Replace STN with STD when storing/checking divert numbers).
1111STNnnn”yyyyyyyyyyy”
Store the primary telephone number yyyyyyyyyyy in
position nnn
1111STNnnn”yyyyyyyyyyy”?
Store the telephone number yyyyyyyyyyy in position nnn
and send a confirmation text message to confirm
storage of new number.
1111STNnnn?
Query the telephone number stored in location nnn. A
text message will be sent to the sender with the stored
number for that location.
1111STNnnn””
Delete the telephone number stored in location nnn.
1111STNnnn””?
Delete the telephone number stored in location nnn. A
text message will be sent to the sender with the delete
confirmation for that location.
nnn is a button number between 001 & 050. The telephone number y can be a maximum
of 30 digits.
Example: To store the number 01912243174 for button 5 and a divert number if that one is
not answered or busy of 01912241558 would be the following two SMS messages:1111STN005”01912243174”
1111STD005”01912241558”
STORING A TELEPHONE NUMBER FOR DIAL IN DOOR RELEASE (STR)
Dial in door release allows users of telephones with their number stored to release the
door/gate simply by dialling the telephone number of the SIM in the intercom panel. The
intercom panel will check the callers ID when it receives a call and if it matches the list of
stored numbers, it will clear the call down (Avoiding the caller being charged for the call)
and will activate the relay for the programmed time. Up to 250 numbers can be stored. The
messages to check, store or delete numbers are as follows.

sending text messages to the intercom panel. The following message changes the code:1111CDEnnnn
nnnn = new 4 digit code
SET DAYS TO WAIT BEFORE MAKING A CALL (NOD)
In the event the intercom panel is not used for long periods of time it could be possible that
the network disconnects it. To prevent this from happening it is possible to program a time
period (From 01 – 99 days) to wait before the intercom panel makes a short call to refresh
the connection. This time period is reset after each call made on the system and will only
happen if the full time period elapses without any incoming or outgoing calls.

FORCED DIAL (DLE)
A useful feature of the Intercom panel is its ability to call a number sent to it in a text
message. This feature can be used when setting up the SIM card. For example, disabling
the voicemail facility or disabling automatic SMS messages or missed calls. Any number
up to 15 digits can be called and the call will last for a maximum of 40 seconds. The
example below would switch off voicemail on a Vodafone SIM card. Substitute the
Vodafone number for other service providers (See important note on page 19).
Dial 1210 for the intercom panel
1111DLE”1210“
Other useful numbers which can be used with this feature are as follows. Please also
check the service provider’s web sits for other useful codes.
Vodafone

Several network providers offer the facility to check available balance on their pay as you
go tariffs. For example, on Vodafone the string is *#1345# and on O2 the string is *#10#.
Other networks may also have this feature. Because the intercom will not know the details
of the network provider’s SIM card which you have inserted it will be necessary to store the
correct string in order to use the credit balance check features.
Store the balance check string for a Vodafone pay as you go.
Store the balance check string for an O2 pay as you go.

UNDERSTANDING THE SIGNAL STRENGTH (SIG)
When a request for signal strength message is sent to the intercom panel it will reply with a two
digit signal strength code. The code will be between 0 – 31 or 99. Ideally the signal strength should
be as close to 31 as possible. The lower the number, the weaker the signal. Signal strengths lower
than 10 may cause operational problems such as loss of speech quality (and possibly missing
DTMF tones) and network loss. A signal strength of 99 indicates it could not be detected.
DIALLING INTO THE INTERCOM FROM ANOTHER TELEPHONE
There are three possible outcomes to dialling into the GSM intercom depending on the
telephone number you are dialling in from and the features setup during programming. The
three possible outcomes are shown in the table below and are shown in order of priority
(For example, if the number is programmed to automatically activate the relay, this will
take priority over the following two options and if the telephone number is stored as a
telephone number called from one of the push buttons, this will take priority over the last
option.
FUNCTION
Dial in to open the door.
After dialling the number, the relay will
activate and the call will be dropped.
Dial in to activate a call (Live speech,
activate relay/AUXO)
REQUIREMENT
The telephone number of the telephone
dialling in must be stored in memory location
STR001 - STR250
PRIORITY
1st
The telephone number of the telephone
dialling in must be stored in memory location
STN001 - STN050 or STD001 – STD050
2nd
If neither of the two requirements above are
met.
3rd
After dialling the number, the call will
be answered and two beeps will be
heard. The speech will then be live.
Dial in to open the speech from a
number not stored in the GSM
memory.
After dialling the number, the call will
be answered and two beeps will be
heard. You will then be required to
enter the four digit code to open the
speech.

GSM DOOR INTERCOM TECHNICAL MANUAL
VER 2.0.5
UNDERSTANDING THE BEEPS
Functions and errors are indicated by beeps from the intercom panel. The following will help you
understand the different beeps heard and what, if anything needs to be done in response to the
beeps.
BEEP
Short beeps at 1 second intervals
Single short beep while the
system is in standby and not
being used.
Two short beeps followed by a
long beep
Long beep followed by short beep
while the system is in standby.
REASON
Relay or auxiliary output activated.
A valid text message has been
received and processed
SOLUTION
None, this is normal
None, this is normal
Button pressed but no number
stored
Invalid text message received.
Long beep followed by short beep
while the system is in use.
Manually ending a call by pressing
a call button
Four long beeps
Not registered with a network
provider but still trying
Six long beeps
Unknown registering problem
Eight long beeps
Registered but roaming for a
better network
Single short beep every 10
seconds after power up
Unable to see the SIM card
Short beep, long beep repeated 3
times
Call button pressed and either the
call is on divert to master or it is
outside the time set in the time
band and there is no master
number stored.
Program a telephone number for
the button pressed.
If this has happened when
sending one of the programming
text messages then check the
message for errors. These beeps
will also be heard if the 4 digit
code in the text message is
incorrect. If you are unsure of the
4 digit code, try resetting it to
1111.
None, this confirms the call has
been cancelled. Another call can
be placed if required.
Leave it a short while to see if it
manages to find the network. If the
beeps repeat every 30 seconds
then try moving the antenna to a
better location or changing the
SIM to another network provider.
Try moving the antenna to a better
location. Try changing the SIM
card to another network provider.
This could happen if it registers to
another network instead of its
primary one. This may result in
higher call charges. Try another
SIM provider for that area.
Check the SIM card is fitted
correctly. Try removing the SIm
card, cleaning and fitting again.
Try a different SIM card.
This may be the required setup
but if it’s not then either change
the time band times, store a
master number to divert the calls
to or open the switch between AO
& G used to switch the calls into
divert mode.

TROUBLE SHOOTING
SYMPTOM
Interference on the speech
TEST
The intercom panel repeatedly beeps twice
and the name plate back light of the module
(Not additional button modules) does not
illuminate.
Check the power supply is of adequate voltage as show
earlier in this manual and that the jumper JP1 is in the
correct position.
Check the signal strength ‘1111SIG?’. If the signal strength
is to low the GSM module which increase it’s power to
compensate causing interference with the speech circuits.
Try relocating the antenna or using a more powerful or
directional antenna.
Ensure the antenna cables are not running close to the
power supply cables or the microphone wires inside the
intercom panel
Try a different SIM card from a different service provider as
they may have better coverage in that area.
Try a full reset as shown earlier in the manual (Powering
up with C2 & PTE shorted).
Try a different SIM card.
Intercom module may have a fault.
A long beep is heard when I press a button.
No telephone number setup for that button. Check the
programming.
Check the SIM card is fitted correctly.
The intercom panel does not respond to
SMS messages
Check the SIM card has a SMS service centre number
stored. This will require putting the SIM card into a mobile
phone to check. Contact the SIM card provider if you are
not sure.
Check the number you are sending the message to is
correct (The number of the SIM card in the intercom panel
After sending a SM to the intercom panel. Listen for a
single short beep from the Intercom panel. This will
indicate that the message was received and understood. If
a long beep is heard it indicates the message was either
not understood or the 4 digit code was incorrect.
Try resetting the 4 digit code to 1111 as shown earlier in
this manual (Powering up with C1 & PTE shorted).
The call keeps dropping out
Increase the call time in programming.
Check the signal strength and if necessary, move or
change the antenna or try a different SIM card provider.
Speech echoes and feeds back
Try lowering the speaker volume using jumpers JP2 & JP3
Try adjusting the volume using the programmable settings
during a call
Check the microphone is fitted correctly in the intercom
panel and that the mic hole is not blocked in any way.
ERROR message returned in SMS when
programming or no SMS returned at all
even though a ? was included at the end of
the message sent.
Check over the message sent again and compare it with
the examples in the manual.
Common errors include:1. Using two apostrophe marks side by side instead of “.
Note that these look the same in the message. An easy
way to see if this is the problem is to move the cursor
along in the message and if the cursor can get between
the two “ then it is not the connect character used.
2. Lower case letters instead of upper case. For example
using stn when STN should be used.
