MANUAL INTRODUCTION

The information in this manual is intended as an installation and commissioning guide for the Vandal resistant GSM door intercom systems using the Art.150 self contained GSM audio module. 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 ten 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). The Art.150 is the GSM module which can be fitted to vandal resistant panel. Features of the module include a dry contact relay output, an open collector auxiliary output, push to exit input and switched 0V auxiliary input. Additionally, a SPEAK, BUSY and DOOR OPEN LED are available on the front of the module (DDA facility) to guide the caller through the call, speak and door open stages of the call. Programming of the telephone numbers and additional features can be carried out via text messaging or dial in. An additional access control feature 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 providers or visit their web sites. The SIM card holder is located under the cover of the amplifier. See Testing, power up and reset for more information.

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 as shown in the picture below:-

IMEI Number

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.

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 panels 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.

PAGE 15 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

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 inside the Art.150 modul. A SIM card from any supplier can be used. Simply push the SIM holder in the direction of ‘OPEN’ and then lift. Insert the SIM card (It will only fit

one way) and then push back down and into the ‘LOCK’ position. IMPORTANT: If this is a new SIM card it may require initialising before inserting into the intercom panel.

- 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.

Power up initialisation sequence

 2 short beeps (RED LED Illuminates)  Approx. 15 seconds delay

 1 short beep (RED LED Goes out)

 Approx. 15 seconds delay  One short beep  System is ready

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 call button telephone numbers.

RESET THE MASTER CODE TO 1111

1. Power down the intercom panel

2. Put a short across C1 & PTE

3. Power up, 2 beeps will be heard followed by a delay and then a further beep.

4. Remove the short after the 3rd beep.

5. The master code is now reset to 1111

FULL RESET

1. Power down the intercom panel

2. Put a short across C2 & PTE

PAGE 16 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

PROGRAMMING

Programming can be carried out either by text message or by dialling into the intercom panel (Certain programming features can only be setup by text message).

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).

PROGRAMMING BY TEXT MESSAGE

Programming by text message is the simplest way to customise the settings of the intercom panel and add or delete telephone numbers. 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.

It may be a telephone number, a time setting or may not be used at all. For more information see the command settings below.

PAGE 17 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

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 A CALL BUTTON TELEPHONE NUMBER

Telephone numbers can be stored for the ten 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 messages to store/check

numbers are as follows (See important note on page 18):-

1111STNnnn”yyyyyyyyyyy” Store the 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 can be found using the following table. The telephone number y can be a maximum of

19 digits.

STORING A TELEPHONE NUMBER FOR DIAL IN DOOR RELEASE

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. The number of numbers thatcan be stored depends on the SIM card’s available memory. SIM cards are normally able to store

100 – 250 numbers. The messages to check, store or delete numbers are as follows (See

important note on page 18):1111STNnnn”yyyyyyyyyyy” Store the telephone number yyyyyyyyyyy in position nnn

where nnn = 100 - 250

1111STNnnn”yyyyyyyyyyy”? Store the telephone number yyyyyyyyyyy in position nnn

where nnn =100 - 250and send a confirmation text message to confirm storage of new number.

1111STNnnn? Query the telephone number stored in location nnn

where nnn = 100 - 250. 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

where nnn = 100 - 250.

1111STNnnn#? Delete and confirm deletion of a telephone number in

location nnn where nnn = 100 - 250.

Memory location nnn can be in the range of 100 – 250. (Important note: Some SIM cards may use some of the memory locations for special features such as checking balance, retrieving voice mails etc. If you are not planning to use all memory location we would suggest storing from location 111 onwards. Use the chart on page 26-27 to record the telephone numbers stored.

Note: It is important to switch off voicemail and automatic SMS features on the SIM card when using this feature. See the ‘Forced Dial’ section for more details. Also note that it will not be possible to use the dial in and program facility from a number stored to release the door/gate when dialling in.

SET CALL TIME

The call time is the maximum time in seconds that a call can last before the intercom panel automatically clears the call down. The time can be from 20 seconds up to 240 seconds (4 minutes) and begins from when the call button is pressed. The default time is 40 seconds. The following messages are used to set/check the maximum call time.

1111SPTnn Store the time nn x 20 seconds (e.g. nn = 03, time = 60

seconds.

PAGE 19 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

1111SPTnn? Store the time nn x 20 seconds (e.g. nn = 02, time = 40

seconds. Also send a confirmation text back to the sender.

1111SPT? Query the current stored time. A text message will be

sent to the sender showing the stored time. (Remember to multiple the number in the received text by 20 seconds)

SET RELAY TIME

The relay time can be from 01 – 99 seconds or latching (Set the relay time to 00 for latched mode. In latch mode, the relay will stay energised until the command is send again).

1111RLTnn Store the time nn = time in seconds. 1111RLTnn? Store the time nn = time in seconds. Also send a

confirmation text back to the sender.

1111RLT? Query the current stored time. A text message will be

sent to the sender showing the stored time.

SET AO (AUXILIARY OUTPUT) TIME (FOR AOM = 01 ONLY)

The AO time can be from 01 – 99 seconds or latching (Set the AO time to 00 for latched mode).

1111AOTnn Store the time nn = time in seconds. 1111AOTnn? Store the time nn = time in seconds. Also send a

confirmation text back to the sender.

1111AOT? Query the current stored time. A text message will be

sent to the sender showing the stored time.

SET AO (AUXILIARY OUTPUT) MODE

There are two mode of operation for the AO terminal:-

User activated: nn = 01 To activate the AO terminal either short AI to C1 or press 6 on the telephone during a call.

CHANGING THE FOUR DIGIT CODE

The four digit code can be any combination of numbers 0-9 but must be 4 digits long. The code allows access to the programming menu in dial in mode and must be used when 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

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.

1111NODnn Store the time nn = time in days. 1111NODnn? Store the time nn = time in days. Also send a

confirmation text back to the sender.

1111NOD? Query the current stored time. A text message will be

sent to the sender showing the stored time.

DIVERT TIME

The divert time is the number of seconds to wait for a call to be answered before diverting to the second number (The divert facility must be set for this to work). The default time is 15 seconds (The count down begins from when the call button is pressed, but is refreshed when the telephone begins to ring) and can be set to 01 – 99 seconds).

1111DITnn Store the time nn = time in seconds. 1111DITnn? Store the time nn = time in seconds. Also send a

confirmation text back to the sender.

1111DIT? Query the current stored time. A text message will be

sent to the sender showing the stored time.

DIVERT SETUP

Divert can be set for any or all of the call buttons. When set, if a call is not answered within the divert time, the call will be forwarded to the second number and the call time will be

refreshed. The following table shows the value of nm used in the programming messages. Default is all diverts disabled (m=0).

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 18). 1111DLE”1210“ Dial 1210 for the intercom panel

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.

Disable voicemail 1210 1760 Disable text alerts #148# 1760

Vodafone O2

NOTE: Disabling voicemail and text alerts is very important as there is no way to retrieve

either of these services from an intercom panel. Disabling these features will also prevent the intercom panel switching to voicemail or sending a text when dialling in from another phone.

STORE SMS AUXILIARY MESSAGE

When C2 & AI are shorted on the intercom panel, a text message will be sent to the number stored in memory location 020. The text message can be customised using the

following message(See important note on page 18) :-

PAGE 22 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

1111SMS”HouseAlarm” Change message to HouseAlarm

Note: The message can be a maximum of 20 characters long and can not include spaces or “.

The memory location used to store the telephone where the text will be send is also the same memory location used for the divert telephone number for button 10 (i.e. 020).

PROGRAM BY ‘AT’ COMMANDS

This is an advanced feature of the system which can allow an AT format command to be sent to the OEM GSM module.

1111PRG(command) Send an AT command to the OEM module

STORE CREDIT BALANCE CHECK STRING

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.

1111SDL”*#1345#” Store the balance check string for a Vodafone pay as you go. 1111SDL”*#10#” Store the balance check string for an O

pay as you go.

PAGE 23 of 36 VR GSM DOOR INTERCOM TECHNICAL MANUAL VER2.0.0

PROGRAMMING BY DIAL IN

Note: programming dial in cannot be used from telephones which are already programmed to open the door when they dial the intercom panel.

When dialling into the GSM intercom from a telephone number which is already stored as one of the call button telephone numbers it will be necessary be press  to switch from call mode to programming mode.

To gain access to the programming menu via dial in, follows these steps:-

1. Call the telephone number of the intercom panel.

2. Wait for the intercom panel to answer and signal by two beeps (If the number you

are dialling from is already programmed as a call button number then you will need to press  before proceeding to the next step).

3. Enter the four digit code listening for a confirmation beep after each digit.

4. If the code is correct, you will here two beeps to indicate programming mode. If the

code is incorrect the call will end and the line will go dead.

Once in programming mode, the following options are available. Remember to listen for a beep after each digit entered. This indicates that it has been received and understood by the intercom panel. The intercom panel will stay in programming mode until the call ends or a timeout occurs. The timeout will occur after 30 seconds if no buttons are pressed. This is reset to 30 seconds each time a button is pressed.

Note: At any point press the # key to clear and begin a programming sequence again. # is also used to confirm and store a new value. After pressing #, two beeps will be heard from

the telephone to indicate successful completion of a command, four beeps will indicate an error in the command.

The following table outlines the available programming codes. These are explained in detail on the following pages.

SYSTEM OPERATION

TO MAKE A CALL FROM THE INTERCOM PANEL

Press the required call button. Two beeps will be heard to indicate the call has been placed and the red LED will illuminate. If a mistake is made, press any other button to clear the call (A long beep followed by a short beep will be heard to confirm the call has been cleared. (Note: If the same button is pressed after five seconds of placing the call this will also clear the call down. Pressing the same button before five seconds will do nothing). When the call is answered, the yellow LED will illuminate.

DOOR/GATE RELEASE

This is signalled by 1 second interval beeps from the intercom panel. Pressing 3 releases the door/gate for the programmed time. Pressing 1 followed by 0 will latch the door/gate in the open position (Note: To unlatch press 3, the door/gate will unlatch after the programmed time. When the door/gate is released, the green LED will illuminate.

RELEASING THE GATE/DOOR BY DIALLING THE INTERCOM PANEL NUMBER

This feature is only possible if the caller’s number has been stored correctly for this feature. Simply dial the number of the intercom panel. The intercom panel will drop the call and then open the gate/door for the programmed time.

USER COMMANDS

The following commands can be carried out during a call: (Note: Successful commands are signalled by two beeps from the telephone, errors are signalled by four beeps).

FUNCTION 1 LATCH RELAY (UNLATCH BY PRESSING 3) 1 0 RELEASE THE DOOR OR GATE 3 N/A ACTIVATE THE AUXILIARY OUTPUT 6 N/A END A CALL 8 N/A ADJUST DOOR SPEECH VOLUME 4 0-9 (0=Lowest, 9 = Highest) ADJUST PHONE SPEECH VOLUME 7 0-9 (0-Lowest, 9 = Highest) ENTER PROGRAMMING MODE DURING A CALL

CHECKING THE BALANCE

*Note: The balance can only be checked if the correct balance check string has previously been stored using the SDL code explained earlier in the manual.

The intercom also has the facility to monitor the available credit and then text you to inform you when it has fell below £5.00, €5.00 or $5.00. It will then remind you with another text after every 5 calls until the credit is either increased or it runs out. To use this feature, the following settings must first be made:-

o You must be using a Pay AS You GO SIM card from a provider that offers this service (Vodafone, O2) o The correct balance check string must be stored using the SDL code. o A mobile phone number in which to receive the balance low text must be stored in location 020 using the

STN code.

UNDERSTANDING THE SIGNAL STRENGTH

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)

After dialling the number, the call will be answered and two beeps will be heard. The speech will then be live.

Dial in to enter programming mode.

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 gain access to the programming menu.

The telephone number of the telephone dialling in must be stored in memory location 100 - 250

The telephone number of the telephone dialling in must be stored in memory location 001 - 020

If neither of the two requirements above are met.

TROUBLE SHOOTING

SYMPTOM TEST

Interference on the speech

The intercom panel repeatedly beeps twice and the name plate back light of the module

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.

Check the power supply is of adequate voltage as show earlier in this manual and that the jumper JP1 is in the correct position.

The call keeps dropping out

Speech echoes and feeds back

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.

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.

No telephone number setup for that button. Check the programming. Check the SIM card is fitted correctly.

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).

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.

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.

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.
