Crestron announced today it is now shipping a new battery-powered photosensor with infiNET EX wireless technology (GLS-LDL-EX-BATT). This dual-loop photosensor provides superior natural light sensing and indoor light control for daylight harvesting applications. Two internal photocells — one for open-loop daylight sensing and one for closed-loop ambient light sensing — effectively cut costs in residential, commercial or retro-fit applications. The GLS-LDL-EX-BATT monitors natural daylight from windows, automatically adjusting shades and lighting to optimize natural light reducing energy usage while maintaining the comfort and convenience of the space and its occupants.
The battery-powered GLS-LDL-EX-BATT can be mounted in a variety of places and communicates with a Crestron control system via an infiNET EX wireless network. The sensor can be mounted to drywall with an anchor and screw, to a drop ceiling or lighting fixture with a magnetic strip, or in a temporary location with adhesive tape. For ceiling mounts, the entire photosensor snaps into a mounting plate that can rotate up to 40 degrees after being secured in place, allowing its position to be fine-tuned after installation.
The GLS-LDL-EX-BATT provides up to 10-years of service via two Lithium-ion AAA batteries. It is designed as a “sleepy” device that will not communicate with other infiNET EX devices unless a certain time or light threshold has been achieved. This ensures that the sensor does not draw on power unnecessarily and that the battery provides maximum lifespan.
