1. General Information
Communicator ET08 / ET081 is a device for transmitting data from alarm system to monitoring station via:
• GSM audio channel;
• GSM audio channel and/or to users via SMS message;
• Telehone landline (PSTN);
• GPRS network.
The system can be used in the following applications:
• Property security.
• GSM network backup for PSTN.
1.1 Operation Description
ET08 / ET081 communicator acts as a gateway between the alarm system and monitoring station providing a dial tone and fully
replacing the landline (PSTN). The communicator noties monitoring station (ET081 ONLY) and/or the preset user by SMS message
in case PSTN is unavailable, has been cut o or disconnected by PSTN provider. ET08 / ET081 supports only outgoing calls. DTMF
number dialing mode in alarm system must be enabled.
ET08 / ET081 can detect temporary service suspension by the service provider for technical or billing reasons even if a dial tone is
still present (optional feature).
ET08 / ET081 features several communication ways between alarm system and monitoring station via:
1. GSM audio channel;
2. PSTN using GSM audio channel as backup connection;
3. SMS messages to preset users;
4. PSTN using GSM audio channel as backup connection with data duplication to preset users via SMS;
5. GPRS network.
6. PSTN using GPRS network as backup connection.
Please, refer to chapter 4. Communication Modes for more details.
The system ET08 / ET081 has 1 digital input (normally open) for sensor connection. The open collector output allows to connect
and control 1 electronic appliance on receipt of the correct SMS text message from one of the preset phone numbers. This feature
provides control over heating, lighting, gates, blinds etc.
ELDES Conguration Tool software is used to congure the system to operate in one of its communication modes, providing data
transmission either via SMS text message or via GPRS. The device has to be connected to the computer using a USB cable. Please,
refer to software‘s HELP section for more details.

3. Installation
NOTE: Due to GSM network characteristics it is recommended that ET08/ET081 be equipped with a SIM card from the same
GSM operator who provided the SIM cards used by users who will receive messages from the system. Thus you will ensure the
quickest SMS message delivery and receipt.
NOTE: To ensure maximum system operation reliability we recommend not to use pay-as-you-go SIM cards. If the balance is
insucient the system will not be able to inform users by SMS or send Contact ID messages.
IMPORTANT: Power supply at alarm system must be disconnected before any installation or tuning work.
The system can be installed in a metal or non-ammable plastic enclosure together with alarm control panel. When the metal
enclosure is also used it is necessary to ground the enclosure using yellow/green colour cable. For the connection use 0.50 mm2
1 thread cable.
Device Installation and Pre-operation:
1. Fasten the system in the enclosure using fastening holders.
2. Place SIM card into the SIM card slot and x it with holder after making sure that SIM card PIN code is disabled. PIN code
can be disabled by inserting the SIM card into mobile phone and following proper menus. SIM card should not have any
remaining SMS messages.
3. Connect the GSM antenna to SMA connector. It is not recommended to turn on the device without GSM antenna connec-
ted.
4. Connect the circuit according to desired communication mode (see chapter 4. Communication Modes)
5. The system should start in less than a minute. GSM LED indicator should be blinking or be ON indicating successful con-
nection to GSM network.

• decodes data to user-understandable text format and continues transmitting it to preset user (-s) by SMS message until the
external PSTN is restored.
NOTE: User phone number (-s) must be set and notication about PSTN loss/restore (if required) has to be enabled for the
communicator using ELDES Conguration Tool. Please, refer to software‘s HELP section for more details.
1. Connect the circuit as indicated in Fig. No. 21 – connect telephone contacts of the alarm system RING/TIP to RING/TIP
contacts of communicator.
2. Connect L1/L2 contacts to external landline (PSTN).
3. Connect L3/L4 contacts to internal landline (PSTN) of PBX.
4. Connect power supply to DC+/COM contacts. Power supply is usually used as AUX- and AUX+ output of alarm system.
5. Set the jumper on MODE pins. See Fig. No. 22 for correct jumper position.

4.11 Communication Mode 11. Data Transmission from Alarm System to
Monitoring Station via PSTN through PBX using GSM Audio Channel
as Backup Connection and SMS Messages to Preset User (-s)
In this mode the communicator retransmits alarm system Contact ID data to monitoring station via landline (PSTN) through pri-
vate branch exchange station (PBX). The communicator also monitors the voltage (dial tone monitoring optional) on the external
PSTN. In case the external PSTN is unavailable, disconnected or cut o (voltage drops below 4V), the system:
• switches to backup connection – GSM audio channel,
•noties monitoring station about PSTN failure,
• sends an SMS report to the preset user (-s) on PSTN failure,
• continues transmitting data to monitoring station via GSM audio channel until the external PSTN is restored,
• duplicates and decodes data to user-understandable text format and sends it to preset user (-s) by SMS message until the
external PSTN is restored.
NOTE: User phone number (-s) must be set and notication about PSTN loss/restore (if required) has to be enabled for the
communicator using ELDES Conguration Tool. Please, refer to software‘s HELP section for more details.

4.12 Communication Mode 12. Data Transmission from Alarm System to Monitoring
Station via PSTN through PBX using GPRS Network as Backup Connection
In this mode the communicator retransmits alarm system Contact ID data to monitoring station via landline (PSTN) through pri-
vate branch exchange station (PBX). The communicator also monitors the voltage (dial tone monitoring optional) on the external
PSTN. In case the external PSTN is unavailable, disconnected or cut o (voltage drops below 4V), the system:
• switches to backup connection – GPRS network,
•noties monitoring station about PSTN failure,
• continues transmitting data to monitoring station via GPRS network until the external PSTN is restored.
NOTE: Notication about PSTN loss/restore (if required) has to be enabled for the communicator using ELDES Conguration
Tool. Please, refer to software‘s HELP section for more details.
I. The following communicator GPRS settings must be set up using ELDES Conguration Tool software:
• CID over GPRS Enabled – enables Contact ID data transmission via GPRS network.
• APN – access-point-name provided by GSM operator.
• User Name – user name provided by GSM operator.
• Password – password provided by GSM operator.
• Server IP – external IP address of the computer running EGR100 software.
• Server Port – forwarded UDP port for the computer running EGR100 software.
Please, refer to ELDES Conguration Tool software's HELP section for more details.
II. The following settings must be set up in EGR100 software:
• TCP/UDP Server Port - forwarded port for communication with the device via GPRS.
Please, refer to EGR100 software's user guide for more details.
NOTE: UDP port must be set the same both on the communicator using ELDES Conguration Tool and in EGR100 software.
