DMP and Uplink Introduce Digital Wireless Solution for Security Monitoring

November 29, 2006

Digital Monitoring Products, one of the few U.S. providers of control panels made in the United States, has announced today the release of the DMP XR500, an integrated intrusion, fire, and access control panel with optional cellular backup. Powered by Uplinks AnyNET-DMP wireless communications device and Numerex Networks, the all-digital solution will provide instant notificationand uninterrupted alarm communicationsto central stations in the event of phoneline outage or Internet service interruption.

The solution includes the Uplink AnyNET-DMP, an onboard communications device integrated with the XR500 panel and Numerex Networks digital wireless service to central monitoring stations. The solution is designed to provide easy web-based administration, quick installation, instant connectivity, flat-rate pricing and automated testing. The integrated solution is quicker to install, and account setup is faster and easier than comparable backup systems. Numerex Networks provides digital service coverage throughout North America, including the Caribbean.

Now the XR500 offers simple, clean back up communication, said DMP Vice President of Sales Gary Kallman. With Uplink the XR500 signals the same receiver, same line card, same IP address as a landline, so it avoids cost increases and the chance for confusion and miscommunications that can happen when cellular backup demands a separate receiver.

The integration of the Uplink AnyNET-DMP digital device represents a significant new product offering for DMP and provides new market opportunities for DMP dealers. DMP customers, both consumers and businesses, now have the option of cost-effective, dedicated protection from a fully wireless security connection, said Chuck Horne, Senior Vice President of Marketing at Numerex.

The AnyNet-DMP is available immediately from Uplink .
