The 9047 is guaranteed to revolutionize the speed in which wireless systems are installed

ISC WEST -- Las Vegas, Nevada, Wednesday, April 2, 2008 – DSC is pleased to announce the PowerSeries 9047 Self-Contained Wireless Panel. This highly anticipated self-contained wireless product is guaranteed to revolutionize the speed in which wireless systems are installed.

With DSC’s new PowerSeries 9047, installation time is significantly reduced when compared to traditional hybrid systems. This provides an opportunity for an increase to the number of installations completed in a day.

The PowerSeries 9047 eliminates the clutter and expense of pulling wire to sensor and detector accessories and has the smallest footprint of any selfcontained wireless alarm system available. Along with the esthetically pleasing design, the PowerSeries 9047 also features instantaneous, 2-way audio VOX and push-to-talk alarm communication with the monitoring station.

Not only is the PowerSeries 9047 from DSC COMPATIBLE with all sensors and detectors, the system is fully UPGRADEABLE to 32 wireless zones and 2 hardwired zones. With a wireless range of 1148 feet, it is FLEXIBLE enough for a variety of applications.

Best of all, it has the same functionality as the proven hardwired PowerSeries Systems with the added bonus of consistent programming structure, template programming and wireless quick enroll to help reduce programming and install times.

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

The PowerSeries 9047 is available in the U.S. and Canada. Its sister product, the PowerSeries 9045, with a number of the same features, is available in Europe, Middle East, Asia, Australia, and Latin America.
