GreenBus by Encelium


The easiest wired lighting communication architecture to specify and install

GreenBus™ by Encelium is a communication architecture technology designed specifically for controlling thousands of luminaires in a building that also integrates peripheral devices such as occupancy sensors, photosensors, relay-based controls, switch packs, and low-voltage wall keypads and touch panels into a complete, programmable lighting control system.

What is unique about GreenBus?

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 and keypads.

GreenBus allows flexible daisy chain wiring topologies and the ability to add luminaires 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.

How does it work?

GreenBus is a two-wire communication topology for supplying data and power to the system. Each luminaire, sensor, and wall controller is daisy-chained back to the Encelium Manager using pre-terminated “click & go” GreenBus communication cabling. Encelium Managers typically control individual floors and are linked via an Ethernet Network. Internet or LAN connection allows floorplan-based control software to be operated anywhere on the network.

The GreenBus communication network is created using two pre-terminated 18 AWG conductors. GreenBus is a Class 2, polarity independent communication bus that connects to the Encelium X Light Management System. The maximum connected length of wiring is 2,500 ft. per channel.

Standard, pre-terminated GreenBus cable lengths of 0.5 ft, 1 ft, 5 ft, 10 ft, 15 ft, 20 ft, 25 ft, 50 ft, and 1,000 ft reduce installation time by eliminating on-site cable cutting, splicing, and crimping.
