The 

Redwood

®

 Engine 3 Model 4834 powers and communicates with 

Redwood

 gateways, sensors,  and  wall 

switches

 to  provide intelligent lighting control and building intelligence. The engine provides a sophisticated level of 

control  w h i c h   s

ignificantly reduces energy consumption. Multiple engines can be linked together to  power and 

control hundreds or thousands of 

fixtures. 

The engine provides communications and control for all types of lighting including LED, 

fluorescent, CFL  and HID. 

In the case of LED lighting, the engine also provides centralized AC to DC power conversion. It  takes high voltage 
200

–250 VAC or 277 VAC input power, converts it to low-voltage DC, and distributes  the power to all fixtures via 

Redwood

 LED sensors and gateways using Class 2, low-voltage cabling. The engine can be located on a rack or 

wall mounted in an electrical or telecom closet.
