Excelsus Z-A431EU Alarm Panel DSL Filter for Europe; Filter Prevents Interference between Alarm Panels and DSL.

SAN DIEGO -- Pulse, a Technitrol (NYSE:TNL) Company, introduces the Excelsus(R) Z-BLOCKER(R) Z-A431EU alarm panel DSL filter for use in Europe. The Z-A431EU eliminates interference that occurs with alarm systems and DSL service, and that often prevents proper operation of some of the alarm panel's features. It is the first alarm panel DSL filter that is compatible with the new European technical standard for alarm systems.

The Z-A431EU isolates high-frequency DSL/HPN signals from low-frequency voice and data signals. This enables simultaneous full functionality of both the alarm panel and the DSL service. The filter supports the line seizure and cut-line protection features of the alarm panel, providing reliable dial-out in case of an emergency or cut line. It also provides uninterrupted DSL/HPN communication during alarm panel incidents, surge protection circuitry for extra customer premises equipment protection from lightning surges and power crosses and two pass-through lines for line monitoring and signaling by the alarm provider.

The Z-A431EU has three filters: one plain old telephone service (POTS) low-pass filter to protect the alarm panel from DSL interference, a second POTS low-pass filter to protect DSL from impedance changes in the alarm panel and a high-pass DSL filter to ensure ongoing DSL service, even during an alarm call.

"Alarm dealers and DSL service providers asked us to solve the problem of interference between alarm panels and DSL," explained Millard Schewe, sales and marketing manager of Pulse's Excelsus products. "Previously they have tried installing splitters or separate phone lines, which can be time-consuming and expensive. A standard DSL filter doesn't work because the alarm panel may not be able to seize the line to dial out in an emergency if it is cut. Customer response to our alarm filter for North America was overwhelmingly positive. We believe the features and performance of the Z-A431EU will receive a similar response in the European market."

The filter is designed for use with many alarm panels in the United Kingdom, France, Italy and other countries that can utilize screw terminal connections. The unit can mount on the wall or inside the alarm panel, and has screw-down terminals for connecting the phone line and alarm panel. It also comes with a quick reference guide containing warranty and safety information. It is compatible with the new EN standard 50131 for alarm/intrusion systems.

The Z-A431EU is available now to alarm manufacturers, licensed alarm service providers and security industry distributors in Europe. DSL customers can contact their local alarm service provider for more information.
