4000 Series GSM Audio Intercom with Proximity
In the example the extended output time for both the relay and auxiliary output 2 (AO2) has been enabled. Since the
original relay time RLT has been set to 05 and the original auxiliary output 2 (AO2) has been set to 10, when either of
these two outputs are triggered the relay time will activate for 5 minutes instead of 5 seconds and auxiliary output 2
(AO2) will activate for 10 minutes instead of 10 seconds. As code 85 was used auxiliary output 1 time (A1T) will still
only operate in seconds (whatever the A1T has been set to).
IMPORTANT NOTE: When the extended output time feature is enabled the respective output is still triggered in the same way
i.e. the relay can still be triggered by pressing 3 on the phone during a call, triggered remotely by sending the text 1111RLY or
if any dial to open numbers have been stored activated when a DTO number dials into the GSM intercom.
OBTAIN THE GSM’S IMEI NUMBER IME
If the IMEI number (the unique 15 digit number of the main internal hardware chip) of the GSM intercom is required the following
text message can be sent to obtain the number.
1111IME? Query IMEI number of the GSM module, also send conrmation to the sender.
Example: Obtain IMEI number of the GSM module, the following message can be sent to the GSM intercom:
1111IME?
The GSM intercom will reply with the following text:
IMEI-357803045065535
VIDEX 4G
IMPORTANT NOTE: If installing the GSM for the rst time, when registering the SIM card with the chosen
network provider they may ask for the IMEI number of the GSM module. As the programming command
described above will only work with a SIM card that has already been registered with a network the
command will not work.
Therefore to obtain the GSM’s IMEI number, located on the main hardware chip internally, the GSM
module will have to be opened. The IMEI number is printed on the main chip label, see Fig.82.
It is recommended that you contact Videx Technical on tel: 0191 224 3174 for UK based customers and
Videx Customer Support: +39 0734 631669 for overseas customers for advise on how to do this.

Alternatively use a SIM that is already registered with another network provider and t it into the GSM intercom (following
the procedure on page 33 for initialisation), then use the programming command above 1111IME? to obtain the GSM’s IMEI
number so that when registering the actual SIM that will be used with the GSM with the chosen network you will have the
appropriate IMEI number to hand.
UNLATCH PREVENTION FEATURE LLA
The unlatch prevention command LLA, when enabled, will prevent a programmed latched output (the GSM’s relay or either of the
auxiliary outputs) from being inadvertently unlatched by a programmed fob/card, access code, DTO number or by pressing the
relevant button (3) on the phone during a call. Even when this feature is enabled if the GSM’s relay or either of the auxiliary outputs
have been setup to latch they can still be unlatched using the relevant 1111RUL, 1111A1U or 1111A2U programming command.
By default this feature is disabled (set to 00), but can be enabled (set to 01). The following programming commands can be used to
enable/disable and check the unlatch prevention feature.
1111LLAnn Set the unlatch prevention feature to nn, where nn = 00 (disabled) or 01 (enabled).
1111LLAnn? Set the unlatch prevention feature to nn, where nn = 00 (disabled) or 01 (enabled). Also
send a conrmation text back to the sender.
1111LLA? Query the status of the unlatch prevention feature stored in the GSM module.
NETWORK CONNECTION INDICATION CON
As well as checking the power & network status indication LED on the back of the 4G GSM intercom (Fig.7,
page 14) to check
which network type (2G, 3G or 4G) the GSM intercom is connected to, the following command 1111CON? can be sent to the GSM
intercom.
1111CON? Check the network type (2G, 3G or 4G) the GSM module is connected to, also send
conrmation to the sender.
Example: To check which type of network the GSM module is connected to, the following message can be sent to the GSM
intercom:
1111CON?
The GSM intercom will reply with the following text:
