Leviton Expands Vizia™ Collection with Z -Wave® -Enabled Wireless Home Control Devices

Wireless Technology Delivers Reliable Lighting and Home Control

Denver, September 14, 2006 - Leviton Manufacturing Company, North America's leading manufacturer of electrical and electronic wiring devices, has expanded its Vizia Collection with Vizia -RF™, a scalable, affordable wireless lighting control system for residential applications. Easy to install, set up and operate, Leviton's Vizia -RF™ Lighting and Home Control system uses Zensys' Z -Wave® technology to overcome the performance issues and high cost of earlier generations of wireless home control systems. The advanced wireless Vizia -RF system includes digital dimmers and switches, along with a full -function scene controller, zone controller, appliance and lamp modules and remote controls. These devices can be installed as a single, stand -alone lighting control network or as part of Z -Wave's larger "intelligent" network of controls for HVAC, access control, intruder and fire detection, appliance control and other home systems.

Vizia -RF's advanced technology offers performance features previously not available in any Z -Wave product. Vizia -RF Plug -In Modules with 'best in class' circuitry and an extended Z -Wave range deliver optimum performance exceeding the performance of other Z -Wave Plug -Ins on the market. The Leviton Plug -In Modules also provide load sensing, the most requested feature in these devices. When a lamp is plugged into a Vizia -RF Lamp Module, users can operate it manually using a switch, pull chain or other lamp -mounted switch. The improved radio frequency range of Vizia -RF also enhances reliability and extends compatibility with other Z -Wave products. Leviton's exclusive two -way protocol actively indicates whether the load is ON or OFF and delivers peak performance without sacrificing compatibility. All Vizia -RF products are backed by Leviton's century -old reputation for quality and reliability.

"Through the integration of Z -Wave's technological advantages with our own legendary standards for quality and reliability in switching and lighting control devices, Leviton is able to offer the industry a generation of home controls that sets the standard for performance, value and dependability,' said Grant Sullivan, Product Marketing Manager for Leviton Integrated Networks and Controls. "Since Vizia -RF devices work well with other Z -Wave enabled devices, users can easily expand their Vizia -RF system by adding products from other Z -Wave Alliance™ partners."

Leviton has joined with more than 125 companies to participate in the Z -Wave Alliance, a consortium of leading -edge companies that are working to incorporate Z -Wave technology into their products. The companies include industry leaders such as Logitech, Honeywell, Motorola, Intermatic, Wayne -Dalton and Universal Electronics. Z -Wave compliant products range from heating and air conditioning, security and safety, access control and appliance control to home entertainment.
