GreenBus™ is the Encelium communication technology designed specifically for controlling lighting to achieve maximum energy savings and optimum lighting comfort.

GreenBus enables cost-effective, individual dimming control of thousands of fixtures in a building and integrates peripheral devices such as occupancy sensors, photosensors, relay-based controls, switch packs, and low-voltage wall keypads into a complete, programmable lighting control system.

Each GreenBus channel originates at an Encelium Manager and typically propagates in a daisy-chain fashion from device to device, although it is topology free and “T” connections are acceptable.

GreenBus is a Class 2 network, which provides low voltage power to all devices on the network eliminating the need for external power supplies and power packs for devices such as occupancy sensors.

GreenBus allows extremely flexible daisy chain wiring topologies and the ability to add fixtures or control devices in-circuit at any time. Different devices may be connected randomly on the network and special termination of each network channel is not required. Automatic addressing of individual nodes during system commissioning simplifies installation by eliminating the need to pre-address devices or record serial numbers during the process.
