Payne-Sparkman’s “distributed intelligent” lighting system, LiteNET, communicates across the LiteTALK twisted pair network to an array of “smart” modules and provides the customer with a lighting network comprised of addressable devices: smart relays, smart switches and sensors, controllers, incandescent dimmers, fluorescent dimmers, low level HID dimmers, even the patented LiteSHADE for complete blackout of any HID fixture.
