For Immediate Release

Dual-Path Alarm Signal Communication with Full Redundancy is Ideal for Commercial Applications

ISC WEST -- Las Vegas, Nevada, Wednesday, April 1, 2009 – DSC is pleased to announce the TL260GS Internet and GSM/ GPRS Dual-Path Alarm Communicator, a complete, integrated solution. As more and more businesses move away from traditional phone lines, towards Voice over IP or digital cellular communication, it is essential to provide alternate methods of alarm communication. DSC’s TL260GS Internet and GSM/GPRS Dual-Path Alarm Communicator conveniently utilizes the existing Internet connection and the GPRS data channel of the GSM network to ensure high speed and RELIABLE alarm communications. Designed for COMPATIBILITY with DSC PowerSeries PC1864/1832/1616 control panels, customers have the option to combine alarm reporting paths through Public Switched Telephone Network (PSTN), Internet and GSM/GPRS channels. The addition of Internet with GSM/GPRS back-up provides complete security and has the extra benefit of providing the opportunity for increased recurring monthly revenue (RMR) for dealers.

Through the Internet connection or the GPRS channel of the GSM network, the TL260GS offers full data reporting and remote management for installers, saving time and reducing costs. With the use of DSC’s DLS IV downloading software, installers can remotely program and configure the control panel, change user information, retrieve historical records, generate status reports and maintenance details from a PC via the Internet or the GPRS data channel.

With 128-bits AES encryption of the alarm signal on both the IP stream and the GPRS data channel, central stations, installers and customers can be assured that this is the most secure alarm communicator offered. And with programmable (by seconds) supervision heartbeats, the communicator’s availability is fully monitored.

The TL260GS connects to the PC-Link connector on the DSC control panel and is easily mounted within the same cabinet, providing the Internet and GSM/GPRS connection that sends predefined SIA format codes to a central monitoring station. For the retrofit installation, simply install this communicator to an already existing control panel and the service is instantly UPGRADED to a triple-path alarm communicator. TL260GS can be programmed remotely by CONNECT 24. Activating and initializing the TL260GS can be done using the automated telephone activation system or visiting the new web-user interface provided by CONNECT 24.

Customized cost-effective rate plans have been negotiated and are available through CONNECT 24 directly or authorized master resellers. Visit www.connect24.com for more information.

DSC designs and manufactures exceptional products that work when it matters most.
