OSRAM SYLVANIA Creates Wireless Version of its Lighting Management System

OSRAM SYLVANIA has launched a wireless version of its Encelium Energy Management System, designed to expand lighting control to hard-to-reach locations. The lighting control system is based on the ZigBee Pro network stack and includes wireless managers, sensors, control modules for attaching to light fixtures, and wallstations. The wireless EMS is being installed at the University of Pittsburgh Medical Center (UPMC) in Pennsylvania.

The UPMC had previously installed an Encelium wired lighting control system covering several of its buildings, but needed a different approach for a three-story, subterranean parking garage, which has wiring pre-cast in its concrete infrastructure. The institution is now installing the wireless EMS to control over 350 lighting fixtures in the parking garage.

The new wireless EMS integrates with both wireless and wired Encelium devices and the Encelium Polaris 3D lighting management software, the core element of the system that facilitates the commissioning, usage and data analysis of the lighting installation.

The wireless EMS consists of the following components:

• The Encelium wireless manager is a ceiling or wall-mounted device that controls up to 100 nodes (control modules, wallstations, sensors, and other devices) and collects, processes, and distributes lighting control information to and from those devices via a mesh network based on ZigBee standards.
• The wireless control module mounts internally or externally to luminaires to connect the fixtures to the wireless network for a variety of tasks. The wireless control module enables each ballast or LED driver to be independently controlled and configured to best meet the needs of the facility.
• Ceiling-mounted wireless sensors collect info on space lighting conditions, and offer passive infra red occupancy sensing and daylight sensing in one housing. The wireless sensors are available in two configurations for up to 450 or 1500 square feet and are battery powered.
• Wireless wallstations send occupant commands to the network, offer the flexibility of being placed where convenient for users, and are a cost-effective option compared to wired switches.
