 Alarm indications which may occur on one or more of the 3 programmable input lines. Bear in mind that 2 voice messages can be
recorded for each of the 3 input lines on the device, one for Activation and one for Resetting.
 PSTN line test. 2 voice messages may be recorded: one for PSTN line absence and one for Resetting.

Power supply voltage test. 2 voice messages may be programmed: one indicating Power supply voltage problems and one for
Resetting.
 Periodic voice message, with a programmable time period between 1 hour and 1 year.
A voice call takes place when an event occurs on a channel for which a voice message and at least one telephone number has been
programmed.
In this case, the Communicator performs the following steps:
1. The Communicator selects a telephone number and forwards the call over the GSM telephone line.
2. The Communicator makes sure that the number is not busy and that there are no problems on the GSM network, so that it can proceed
with the next step, otherwise the call will end and step 1 will be attempted again, up to a maximum of 8 times (depending on the
programmed value). After 8 attempts the call cycle will be considered complete. If the alarm channel has been programmed to call
several telephone numbers, they will be called in a set sequence. By doing this, for example, the possibility of calling a busy number
several times in the space of a few seconds can be avoided.
3. The Communicator waits for a response from the number called for a period of up to 60 seconds. If the outcome is positive, the
Communicator moves on to step 4; otherwise the call will end and step 1 will be attempted again, up to a maximum of 8 times (depending
on the programmed value). After 8 attempts the call cycle will be considered complete.
4. The Communicator reproduces the message corresponding to the channel experiencing alarm status; the call is only considered
complete once the

button (if programmed) on the telephone receiving the message has been pressed. In any case, the call is
considered successful after the message has been repeated up to a maximum of 8 times (depending on the programmed value). If, at
the selection stage, several events occurred causing several different messages to be sent to the same telephone number, these
messages are reproduced (each for a maximum of 8 times, depending on the programmed value) in sequence during the same
telephone communication, thus avoiding calls being made to the same number several times. If at the end of the call cycle, the line which
caused the Communicator to be activated is still in alarm mode, the procedure described above will not be repeated again. In fact, the
line that caused a call cycle must return to standby mode before a new cycle is activated.
Priority management (GS3125 series only)
The Communicator can be used to transmit alarm events and SMS or voice messages; several priorities may be programmed using the
GS3100 Series Console software (please refer to the section corresponding to programming procedures using the GS3100 Series
Console software). The table below lists the default priority management settings.

Simulated telephone line priority
When the device connected to the LI terminals requests the line, any other call made at that moment in Voice dialer mode will be terminated. The
calls requested by the device connected to the
LI terminals (a burglar alarm control unit, for example) take place in this manner. When the device
connected to the LI terminals frees the line, the voice dialer will resume the suspended calls and begin sending voice messages again.
SMS dialer priority
If a piece of equipment connected to the LI terminals is making a call over the GSM network through this dialer and an SMS dialer action
needs to be performed, the call from the interface will not be terminated and the SMS message will still be sent.
Dialer event priority
The SMS messages have a lower priority than Voice messages but they can not be interrupted while they are transmitted: in this case, the
queued Voice message will be sent at the end of the SMS message sending.
