RATIO, by B.E.G. Controls, is a true innovation in digital architectural scene room control. Up to 16 scenes and 16 groups can be created with motion sensing and daylight harvesting from only 3 control components, delivering robust and dynamic digital lighting control. The centerpiece of RATIO is the FLAT multi-sensor. Virtually flush at less than 1 mm depth, FLAT has impressive passive infrared motion detection range with daylight harvesting. A Bluetooth-enabled momentary push button module with four independently configurable button inputs lets you specify the wall station style you want, not just the limited choices normally offered. The RATIO power supply delivers bus power for RATIO controls and DALI devices. Setup is accomplished via an intuitive smartphone app, which can also be used for remote control. RATIO is scalable, aesthetic, digital architectural scene control made simple.
