Data Sheet Digi-Touch® Network
Overview Eliminate Line Voltage Home-Runs Digi-Touch® Network system extends the functionality of Lumisys’ panels and Qwik-Kits by providing the capability of networking digital switches over a single twisted pair of wires. This twisted pair network is Lumisys’ Digi-Touch Network. Significantly less wire needs to be run and maintained when utilizing a Digi-Touch™ Network as compared to a traditional wiring process; thereby reducing installation costs by eliminating the need for multiple low voltage and line voltage home run wiring.
