L Lighting control system provides an efficient and cost-effective alternative for HID lamp lighting applications that previously required fluorescent lighting in order to achieve energy savings. The lighting control reduces energy costs for HID lighting fixtures by 25% to 33%. The model enables automatic control, manual control and remote control for high-performance lighting.(VB400 by IEPC Corp.) www.iepc.cc #25 E Protection system controls medium to large-sized AC generators. The device allows the monitoring of instabilities in the power systems and sees how instabilities are affecting the points of generation. The system sup- ports accumulated over- and underfrequency protection that monitors the amount of time a generator has been running at off-nominal frequencies and then triggers alarms. (G60 Generator Protection System by GEMultilin) www.GEMultilin.com #26 battery powered with long MTBF and the router/repeaters are line-powered modules that extend the range of the network and provide alternate routing paths. (A3 Sensor Net by Spinwave Systems) www.spinwavesystems.com #27 A L Ethernet network interface unit facilitates remote access to a commercial building’s lighting control network. The unit monitors the status of lighting loads, makes changes to the control system and overrides lights remotely. It also is able to bridge various lighting control systems that are on the same network. The device comes in sizes as small as 2.83 in. x 2.65 in. (Clipsal® by Square D) www.squaredlightingcontrol.com #28 Wireless mesh sensor network features a system that eliminates interference from RF sources while minimizing power consumption. The device is designed to switch RF channels and avoid the sources of other RF interference. The wireless network also features open architecture and can adapt to other industry protocols based on the IEEE 802.15.4 standard. The sensors in the device are A 2007 CALL FOR ENTRIES Deadline : October 15, 2007 ARC Awards honor Engineers and Engineering Firms that incorporate unique Mechanical, Electrical and Plumbing design elements into commercial, institutional, and industrial building projects.
