From the Manufacturer Wireless self-powered technology means no new wiring is required. Leviton LevNet RF Wireless Self-Powered Solutions are easy to install and maintenance-free, saving ongoing labor and material costs while saving energy. EnOcean technology allows energy harvesting LevNet RF Transmitters to operate indefinitely without the use of batteries. The motion of a switch actuation, light on a solar cell, or temperature differentials in the environment provide power to LevNet RF Transmitters, allowing zero maintenance wireless devices. The LevNet RF line includes multiple products that operate in the uncrowded 315MHz band offering greater transmission range (50-150 feet) and minimal competitive traffic. LevNet RF Remote Switches can control an unlimited number of LevNet RF Receivers that are in range. LevNet RF Remote Switches use no wires or batteries. Pressing the switch or inserting a hotel key card into a switch provides the energy to transmit a wireless signal that controls lights or other devices connected to LevNet RF Receivers. Wireless Switches are primarily used to control lights in businesses or homes, but they can be used to control virtually any on/off device. Each Wireless Self-Powered Remote Switch can be placed anywhere within range of a Receiver. Traditionally the Remote Switch is surface mounted on a wall with screws or industrial tape, but can also be used in a standard switch box or as a wireless handheld remote. The unique ID of each Switch activates only the intended Receiver(s). Wireless, self-powered technologies make them the ideal solution for retrofits and new construction; installation is quick and easy with no additional wiring required. It takes only minutes to install and configure. Control one light or one group of lights with the Wireless Self-Powered Single Rocker Switch. One switch can control an unlimited number of LevNet RF Receivers that are within range. Wireless receivers and transmitters sold separately.
