ET082 GSM/GPRS COMMUNICATOR
4.GENERAL OPERATIONAL DESCRIPTION
ET082 communicator is used with third-party PSTN/non-GSM alarm panels as a communication gateway via GSM and IP-based networks
for data transmission from the alarm panel to monitoring station and/or preset user phone number by SMS text message.
The device comes equipped with PSTN line state monitoring feature that in case of PSTN line loss would result in switching to a pre-
congured communication method, such as GSM, SMS, GPRS, until the PSTN line is restored followed by notifying the monitoring station
and/or preset user phone number by SMS text message. The device can detect a physical PSTN line cut-o or even when a dial tone is still
present due to temporary service suspension by the service provider for technical or billing reasons (requires Smart PSTN module).
The device has 3 digital inputs (normally closed or normally open) for alarm device’s PGM output or detection device connection, such as
magnetic door contact. By connecting the input to a non-GSM alarm panel’s PGM output, up to 3 preset user phone numbers will be able to
receive an SMS text message as well as to notify the monitoring station regarding arming/disarming and other events depending on the
alarm panel conguration.
The device comes equipped with 3 open-collector outputs allowing up to 3 preset user phone numbers to turn ON or OFF the electrical
appliances, such as heating, lighting, lift the gates, blinds by free of charge phone call or SMS text message. Alternatively, the outputs
can be controlled automatically based on the associated ET082 input alarm/restore event. The outputs can also be used for PSTN or GSM
connection loss indication as well as for arming/disarming by connecting an output to one of the alarm panel’s zones pre-congured as a
keyswitch.
The device will ignore SMS requests and phone calls coming from non-preset phone numbers.

• RING/TIP interface – The alarm panel is linked up with ET082 communicator via the RING and TIP terminals simulating the connectiv-
ity of the PSTN line. For more details, please refer to 6.1. RING/TIP Interface
• Keybus interface – The alarm panel is linked up with ET082 communicator via the keybus (serial data) interface just like the alarm
panel accessory, such as keypad. For more details, please refer to 6.2. Keybus Interface
ATTENTION: Only one of the aforementioned methods is supported at a time.
6.1. RING/TIP Interface
Using this communication wiring method, the communicator simulates the PSTN line presence for the alarm panel. Depending on the
PSTN line accessibility in the installation area and user requirements, the communicator can be wired to the alarm panel using one of the
following diagrams:
• No PSTN line – The communication link between the alarm panel and the monitoring station is established using ET082 device in the
middle. The communicator retreives data from the alarm panel and transmits it to the monitoring station via the pre-congured com-
munication method. PSTN line is completely excluded from the communication process.

1. Connect the communicator’s RING and TIP terminals to the alarm panel’s RING and TIP terminals respectively.
2. DOT NOT set any jumpers on the communicator’s JP8 and JP9 pins.
• With PSTN Line Supervision – The communication link between the alarm panel and the monitoring station is established directly
via PSTN line adding PSTN state (terminals L3 and L4) supervision provided by ET082 communicator. The communicator is not involved
in the communication process while PSTN connectivity is available. In case of PSTN loss (terminals L3 and L4), the communicator will
take over the communication link and continue data transmission via the pre-congured communication method as described in No
PSTN Line until PSTN connectivity is restored.

1. Connect the communicator’s RING and TIP terminals to the alarm panel’s RING and TIP terminals respectively.
2. Connect L3 and L4 terminals to the PSTN socket.
3. Set the jumpers on the communicator’s JP8 and JP9 pins.
• With External PSTN Line Supervision – The communication link between the alarm panel and the monitoring station is established
directly via PSTN line connected via PBX (private branch exchange) adding external PSTN state (terminals L1 and L2) supervision
provided by ET082 communicator. The communicator is not involved in the communication process while PSTN connectivity is
available. In case of external PSTN loss (terminals L1 and L2), the communicator will take over the communication link and continue
data transmission via the pre-congured communication method as described in No PSTN Line until PSTN connectivity is restored. In
case of internal PSTN loss (terminals L3 and L4), the PSTN connectivity would remain present.
