Rockleigh, New Jersey (PressExposure) January 26, 2009 -- Crestron Green Light occupancy sensors are now available to enhance the functionality of Crestron Green Lightâ¢ environmental controls. The new Crestron occupancy sensors have built-in microprocessors and photocells to significantly reduce on-time for lights, cutting energy usage. Climate and device control can also be integrated. Models include wall and ceiling mount versions with a variety of coverage ranges.
Crestron Green Light sensors continually analyze and adjust to changing conditions, using the latest in microprocessor-based technology to optimize performance. Dual-technology (ultrasonic and passive infrared) sensing delivers optimum detection of motion while minimizing the effects of false triggers, such as electrical noise, air currents, and temperature changes. Passive infrared-only versions are available as well.
Upon activation, each sensor initiates in âwalk-throughâ mode. âWalk-throughâ mode is active for a two and a half minute interval, during which lights turn off promptly when a person enters and exits the room. After the 2.5 minute period of occupancy, the sensor shifts into âoccupiedâ mode.
âDelayed offâ is initially set via the timer knob on the sensor, turning lights off when no motion is detected after a specific time. While the sensor is in use, the sensor learns room occupancy patterns. The delayed off time will change as the sensor intelligently adapts to environmental conditions and occupancy patterns.
When enabled, the built-in photocell overrides the occupancy sensor if the ambient light level is above a set threshold, preventing lights from turning on when there is sufficient daylight in the room. Sensor behavior can be customized via the Crestron control system.
