1. A decentralized low-voltage bus for managing a load circuit, the decentralized low-voltage bus comprising:
- a) a plurality of nodes;
b) a control unit at each of the nodes;
c) a sensor directly coupled to at least one of the plurality nodes;
d) a control switch directly coupled to at one of the plurality of nodes;
e) lights electrically coupled to at least one of the plurality of nodes; and
f) means for changing a mode of operation of the sensor or the control switch wherein the lights are controlled by the control units in response to control signals from the sensor unit and the control switch that are transmitted over the low-voltage bus.

Abstract
A system and architecture for managing lighting through a seamless low-voltage bus network is disclosed. The system comprises a plurality of control units that serve as nodes for integrating devices, such as light fixtures, control switches and sensors into the bus. Each of the control units preferably includes a printed circuit board and node interconnects for assembling the low-voltage bus and for integrating the devices. Alternatively, the system comprises a central hub with a master printed circuit control board and a plurality of interconnects for assembling the bus and for integrating the devices.
