For Immediate Release

Communicator can be used in both a primary or backup role

Las Vegas, Nevada, Wednesday, April 2, 2008 – Powered by DSC’s legendary RELIABILITY and QUALITY, our GSM universal wireless communicator (GS3060) connects the alarm control panel to the GSM network and reports alarm signals directly to a central monitoring station. For those customers not using a traditional public switched telephone network (PSTN) phone line, the GS3060 can be utilized as a primary alarm communicator. The GS3060 uses the GPRS data channel of the GSM network to ensure low-cost, high-speed and reliable alarm communications and is COMPATIBLE with most control panels that communicate using the Contact ID format.

The GS3060 is installed between the telephone connection of a control panel and telephone line. When used in a backup role, the communicator assesses the connection to the PSTN phone line, and if that has failed, it then connects to the GSM network to send an alarm signal to the monitoring station. In a primary role, the communicator simply sends the alarm transmission over the GSM network immediately. Alarm signals are transmitted directly without the need of a clearinghouse to the IP line card of the monitoring station receiver (such as Sur-Gard System II/System IIl). Whether used in its primary or backup role, the GS3060 has the FLEXIBILITY customers require.

Activating and initializing the GS3060 can be completed using the automated telephone activation system (VRU) or also by web-user interface provided by CONNECT 24.

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

The GS3060 Universal Wireless Alarm Communicator is available in the U.S. and Canada. For more information visit www.dsc.com, ISC West booth #23001, or online at www.dsc.com.
