4000 Series GSM Audio Intercom - Technical Manual
4000 Series GSM Audio Intercom with Proximity
onboard relay is activated. The alternative mode can be set to ‘00’, whereby the internal speech board will announce “the door is
open”. To set the required mode the following commands can be sent to the GSM module.
1111GATnn Set the speech board annunciation to mode nn: 01 or 00 (01 = “the gate is open”, 00 = “the door
is open”).
1111GATnn? Set the speech board annunciation to mode nn: 01 or 00 (01 = “the gate is open”, 00 = “the door
is open”) also send a conrmation text back to sender.
1111GAT? Query the speech board annunciation mode set.
SHUTDOWN AND RESTART RBT
This command feature allows the GSM intercom to be remotely shutdown and then rebooted again. The following command can
be sent to the GSM module.
1111RBT Shutdown and restart the GSM module.
IMPORTANT NOTE: This feature should not be confused with the ‘hard-wired’ reset (described on page 34). The RBT function
simply powers down the GSM module and then powers it back up again.
SIMULATE A BUTTON PRESS VIA SMS MESSAGE FOR BUTTONS 0150 BUT
It is possible to simulate a button press (for the call button range 01 - 50) on the intercom by sending the following programming
command, shown below, to the GSM intercom. This feature can be useful if there is suspected fault with a call button or if there is
an issue with the wiring for the buttons into the GSM’s button matrix.
1111BUTnn Simulate a button press for button number nn, where nn = button number 01 - 50.
The following commands are reserved for the technical department for interrorgating the GSM module when testing and applying
specic additional features that are not covered in this technical manual. For the application of these commands please contact
Videx Technical on tel: 0191 224 3174 for UK based customers and Videx customer support on tel: +39 0734 631699 for overseas
customers.
ENABLE EXTENDED OUTPUT TIMES EXO
The extended output time feature EXO allows the existing output time of the GSM’s relay (RLT) and two auxiliary outputs (A1T
and A2T) to be increased for every second programmed to be extended to 1 minute. For example if the relay time RLT was set to 5
seconds and the extended output feature was enabled then the relay time would become 5 minutes.
There are 7 set extended output codes, from 81 to 87, that can be used. When one of these codes is used (refer to the EXO code table
below) it will allow one or a combination of the outputs to have an extended output time. For example if code 83 was used then
both the relay and auxiliary output 1 will have the extended output time feature enabled. So whatever the programmed relay time
RLT and auxiliary output 1 time A1T are set to the time will be in minutes and not seconds and this will be the time the respective
output will activate for. In this example auxiliary output 2 time A2T would still be set in seconds.
EXO code Output(s) EXO code Output(s) EXO code Output(s)
81 Relay 82 AO1 83 Relay and AO1
84 AO2 85 Relay and AO2 86 AO1 and AO2
87 Relay, AO1 and AO2 32 disabled (default)
By default this feature is disabled (set to code 32). The following texts can be used to set the extended output time.
1111EXOnn Enable the extended output time for the required output(s) using EXO code nn, where nn = 81 -
87 (refer to EXO code table).
1111EXOnn? As above and also send a conrmation text back to the sender of EXO code.
1111EXO? Query the stored EXO code.
Example: To enable the extended output time of the GSM’s relay to 5 minutes and auxiliary output 2 to 10 minutes, the GSM’s
relay time RLT must rst be set to 5 seconds using the 1111RLT05 command and auxiliary output 2 (AO2) must rst
be set to 10 seconds using the 1111A2T10 command. Then the following text message can then be sent to the GSM
intercom:
1111EXO85?
Including a ? at the end of the programming command the GSM intercom will reply with the following text:
EXO = 85
