The CU-250 Ultrasonic Multi-way Vacancy Sensor provides automatic lighting shutoff for a variety of applications including
those with multiple switch locations. It is engineered to comply with specific provisions of California’s Title 24-2013 energy code.
The CU-250 operates as a manual-on sensor. Users must press the pushbutton to turn on lighting. The CU-250 employs 40kHz high frequency ultrasound to sense motion within an enclosed space, and does not require a clear line of sight for proper operation. It keeps lighting on as long as motion is detected and provides automatic shutoff, following a user-selected time delay, when motion is no longer detected. Users may turn the connected load off manually.
A CU-250 connected to other CU-250s and/or RH-253 Decorator Single Pole Momentary Switches provides true multi-way on/off control. An occupant simply presses the on/off pushbutton of any connected device to turn on the lighting. Lights remain on as long as one of the CU-250s continues to detect occupancy. The user may turn off the lighting by pressing the on/off button on any of the connected devices. If the room becomes vacant and lights are on, they will be switched off automatically following the time delay of the last CU-250 to detect occupancy.
CU-250s are ideal for bathrooms, L-shaped rooms, storage areas and other applications where the sensor may have an obstructed view of the covered area.
