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

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 Alarm Communicator plays the message corresponding to the channel where the alarm is taking place, the call is
considered completed only once the message has been received, or when the
key is pressed (if “Call Confirmation” has
been selected, see the Voice dialer->Call Confirmation section) on the phone receiving the message. 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.

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 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.
in this case, the queued Voice message will be sent at the end of the SMS message sending.
