GSM/GPRS Alarm Communicators
Pay As You Go Balance (GS3125 series only)
If the GS3100 Series Console software has been used to program the device (see Options->Pay As You Go ), it will be possible to check
how much credit is left on the pre-paid SIM CARD. If the credit balance check feature is enabled, an SMS providing credit balance information
(supplied by the operator) is sent to the
first number in the phonebook at regular intervals. In Italy the operator (TIM, Wind, Vodafone)
is recognised automatically, so the credit balance check also takes place automatically. For all other operators which support credit balance
requests via a network command, it will be possible to enter a request for information using the GS3100 Series Console software.
     PLEASE NOTE - The pre-paid SIM CARD credit management service may be suspended at any time, at the discretion
of each individual GSM network operator.
(PTM) monitoring of communication with the control unit
The constant monitoring of communication with the control unit (PTM function) allows the Communicator to transmit calls via the GSM
network if communication between the alarm control unit and the surveillance control unit does not take place successfully over the PSTN
telephone line. If programmed (using the GS3100 Series Console software
PTM page), this feature only works when the PSTN line is
connected to the LE terminals.
The PTM function correlates to the following Communicator alarm transmission modes:
1. Alarm on GPRS (IP communication - receiver).
2. Alarm on GSM (voice mode).
     The PSTN Fault event occurs when the PTM function activates.
ACTIVATING THE OUTPUTS
The GS3105 series has the Open-Collector Outputs (the T1, T2 and T3 terminals). The GS3125 series has 3 terminals (the T1, T2 and
T3 terminals) that can be programmable as Inputs or/and Output: this terminals are programmed as Outputs by default. The Open-
Collector Outputs can be activated automatically (when certain pre-programmed events occur) or remotely, through SMS trasmission (for
the GS3125 series only) or caller identification from a number programmed previously.
Activating/Deactivating Automatic Outputs
The T1, T2 and T3 Open Collector outputs can be activated automatically by the following events:
 Land line trouble (line down), (T1, GS3105 series only).
 GSM Network trouble (Limited/No Service), (T2, GS3105 series only).

Supervision message missing.
 Internal event communication failed (FTC).
    
Once an output has been activated automatically, it will not restore its state until all the causes of activation clear.
Remote Activation and Deactivation of the Outputs
     CAUTION - The GSM connection must be established before the outputs can be activated/deactivated remotely.
We recommend the device is programmed with the Black list enabled (Options->Dial Options) and White list disabled
(Phonebook->White list) for the numbers you wish to use for this function.
The number used to activate the outputs via Caller Identification must be visible.
GS3105
The T1 and T2 Open Collector outputs as BISTABLE , while the T3 output is MONOSTABLE (Once a Monostable output has been
activated, it will not deactive until On Time expires).
GS3125
The Open Collector outputs can be set as Bistable (activation and deactivation takes place by means of 2 separate commands) or
Monostable (the output remains active for the ON time and returns to standby mode when this period has elapsed). Moreover,
every output can be programmed to provide a confirmation signal (an SMS programmed previously if output activation/deactivation is
performed via SMS, or a confirmation ring if output activation/deactivation is performed via caller identification).
