Unicel Architectural Corp.'s motion sensor operation technology accompanies its Vision Control IGU. The new operator is compliant with the Americans with Disabilities Act (ADA) and includes two sensors enabling easy and automatic louver operation, with one sensor activating the louvers’ upward direction and the other activating the downward direction. Momentary hovering above either of the sensors triggers the louvers to close in the desired direction. Continuous hovering triggers the louvers to tilt until the hand is removed from above the sensor, allowing for precise control of louver angles.
