LX20G transmitters are modern microprocessor devices for real time data transmission which can simulate a telephone line (PSTN) with transmission on a GSM voice channel. In case of telephone line (PSTN) failure or after dialing specific prefix number, devices establish voice connection with monitoring station and enable data transmission using Contact ID (DTMF) or SIA (FSK). Also available are other transmission channels - GPRS and SMS.

Thanks to LX20G GPRS Transmitter/GSMDialer/GSM Gateway it is possible to make downloading even, when PSTN network isn't connected to protected premises. Additionally no PSTN modem is needed at installer site. Data is transmitted over the GPRS network which reduces the cost of transmission. Installer must only have access to the LX20G device via OSM server at monitoring station and have access to the network with incoming traffic from LX20G enabled (public IP address or TCPport redirected in case of public APN orconnection to corporate private APN).Configuringcontrol panel remotely using LX20G is stillperformed using control's panel configurationapplication supplied by control panel manufacturer. Instead of connecting PSTN modem to it, ModemEMU application supplied by EBS is used which translates modem communication format to GPRS transmission with LX20G transmitter. LX20G decodes GPRS dataand translates it to the Bell103 format used bycontrol panel.


- Costs savings: remote technical controls of control panels, remote configuration and service;
- No need to have telephone line;No need to have PSTN modem;
- Possibility to check the proper functioning of the control panel from monitoring station;
- Efficient verification of false alarms;
- Faster response to any irregularities in the operation of control panel;
- Supervision over the work quality of the installer.
