Watt Stopper/Legrand introduces the RD-200 Dimming Wall Switch Vacancy Sensor. By combining a preset dimmer and a sensor, this device helps homeowners enjoy the most pleasing light level for each activity and maximize energy savings. The RD-200, which is the newest addition to Watt Stopper/Legrand’s line of residential vacancy sensors, complies with California Title 24 requirements.
Watt Stopper/Legrand has developed lighting control solutions designed to enhance high-end, modern construction. The company’s newest commercial occupancy sensors incorporate sophisticated design details that make them aesthetically pleasing as well as easy to operate. At the same time, each elegant package is manufactured to withstand the rigors of commercial use; both the robust housing and the control electronics are engineered for longevity.
The Square D® Clipsal® Pascal Automation Controller from Schneider Electric enhances the capabilities of a Square D Clipsal lighting control system by providing expansive scheduling capability and facilitating operation of third-party products from input devices such as keypads and touch screens in both residential and commercial applications. The Pascal Automation Controller is easily installed by an electrical contractor, using standard Cat-5 cable. Third-party products, such as a movie projector, screen, and security or HVAC systems, are connected to the Pascal Automation Controller via its two RS232 ports.
The Siloam Family Health Center in Nashville, Tenn., has employed an energy cost-savings strategy using Square D® Wall Switch Occupancy Sensors from Schneider Electric, allowing allocation of more budget to maximizing patient care. The sensors, which use passive infrared (PIR) technology to detect occupancy, requires a button press to activate lighting in occupied rooms much like a standard light switch. If lights are accidentally left on when the room is vacated, the sensor automatically turns them off after a preset time delay. Forty sensors were co-donated by Schneider Electric’s three Middle Tennessee locations — Nashville, La Vergne and Smyrna — in December 2007, as part of the facilities’ Mission for the Community initiative.
The Lighting Controls Association (LCA) has announced the availability of EE204: Hi-Bay Lighting Upgrades, a new course added to its popular Education Express program. Residing at the Association’s website, Education Express provides in-depth education about lighting controls and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as LEED, energy codes and other trends.
Leviton Manufacturing Company Inc. has announced that it has entered into an agreement to acquire ControlThink LC, a leading home and building control software and services company. The acquisition will join Leviton’s strengths in product manufacturing and distribution with ControlThink’s PC-, CE- and mobile phone-based solutions for intelligent home control.
Advance has announced that a variety of its electronic ballast offerings have become charter products within the voluntary new NEMA Premium® Ballast Program.
In terms of lighting, ASHRAE 90.1-2007 clarifies the Standard’s intent and enacts several refinements but otherwise doesn’t revise the lighting power density (W/sq.ft.) limits from the 2004 version, which itself was 20-25 percent more stringent than the 1991/2001 versions.
