Programming the GSM Intercom
FORCED DIAL/DIAL A NUMBER (DLE)
A useful feature of the GSM 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.
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 sites for other
useful codes.
Vodafone
O
2
DISABLE VOICEMAIL
1210
1760
DISABLE TEXT ALERTS
#148#
1760
IMPORTANT NOTE: Disabling voicemail and text alerts is very important as there is no way to retrieve either of these services
from a GSM intercom panel. Disabling these features will also prevent the intercom panel switching to voicemail or sending a
text when dialling in from another phone.
CHANGE THE FOUR DIGIT CODE (CDE)
The four digit code can be any combination of numbers between 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 GSM intercom panel. Use the following
message to change the code.
1111CDEnnnn
Change the 4 digit code to nnnn (where nnnn = new 4 digit code).
TRIGGER THE RELAY (RLY)
There are several ways to trigger the GSM relay. The first is to press button 3 on the telephone during a call and the relay will operate
for the programmed time. Another way is to send the following text message.
1111RLY
Operate the GSM relay (for the programmed time).
1111RLY?
Operate the GSM relay (for the programmed time) and send a confirmation text back to
the sender.
TRIGGER AUXILIARY OUTPUT AO (A1O)
It is possible to trigger the auxiliary output AO for the programmed
A1T
output time (please note that this method of triggering
auxiliary output AO is only possible when the
A1M
mode has been set to mode 01, refer to page 41 and the example on page 26).
The auxiliary output AO can be triggered by pressing button 6 on the telephone during a call or by sending the following message
to the GSM intercom.
1111A1O
Trigger auxiliary output AO (for the programmed A1T time).
1111A1O?
Trigger auxiliary output AO (for the programmed A1T time) and send a confirmation text
back to the sender.
STORE BALANCE CHECK DIAL STRING (SDL)
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
2
pay as you go.
IMPORTANT NOTE: Videx are only aware of the balance check dial string codes for the network providers mentioned above.
Check dial string codes for other networks are currently unavailable at this time. Please also note that this programming
function is only applicable for pay as you go SIM cards.
CHECK CREDIT BALANCE (BAL)
The balance can only be checked if the correct balance check string has previously been stored using the
SDL
code explained
above. At any point the user will be able to send the following text message and the GSM intercom will reply with the current
balance stored on the SIM card.
