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. For all
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).
GSM Network trouble (Limited/No Service), (T2, GS3105 series).
Supervision message missing (GS3125 series only).
Internal event communication failed (FTC), (GS3125 series only).
Once an OC output has been automatically activated, it will only return to standby mode when all the causes
of activation have been cleared, except if there is a Failure To Communicate an internal event (FTC), in which
case it returns to standby mode after the ON Time has expired.
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).
