With HAI's Omni-Bus Lighting Network you can experience all of the benefits of a sophisticated lighting control system. Lighting control can enhance the enjoyment and value of your home, add security for peace of mind, and contribute to savings on your energy bill. Control lights, shades, fans, shutters, pumps, and much more with HAI Omni-Bus. Power modules feed power to dimmer or non-dimming switches. Each switch wires to a DIN rail module. The power for the circuit also goes to these DIN rail modules, thus switches are not directly wired to lights but rather to the modules controlling the lights. As with third-party solutions, Omni-Bus lighting works by a low voltage wire from the hardwired switch to the dimmer DIN rail module, but with the distinctive advantage of being an HAI product.
