The best of both worlds - Legrand combines the benefits of passive infrared (PIR) and ultrasonic technologies to automatically control lighting based on occupancy. High sensitivity to small and large movements, an attractive design, and a host of features make this a must have for the energy conscious consumer.

Choice of Automatic-ON or Manual-ON operation allows you to select what you need
Featured Detection Signature Processing is built in, prevents false triggers, and protects from RFI and EMI
Operates at 120/230/277 VAC
Walk-through mode makes potential energy savings even greater
Tamper and vandal-proof lens combines precision with rugged durability for long lasting use
Select the audible alert feature to hear when the lights will be shutting off before they do
Four occupancy options allow you to select the lighting you need
The override feature allows you to use your sensor switch manually in the event of a failure
Meets with NEMA WD 7 guideline utilized for coverage testing
UL and cUL listed
Available in white, light almond, ivory, gray and black to match your décor
5-year manufacturer’s warranty

This dual technology operates by detecting Doppler shifts in transmitted ultrasound and passive infrared heat fluctuations. You control the technology and settings with easy to manipulate DIP switches.

Ultrasonic sensing with a frequency of 40 KHz
SmartSet™ technology will automatically fit occupant usage patterns
Activate SmartSet with a DIP switch
Sensor shall utilize Zero Crossing circuitry to reduce stress on relay and therefore increase sensor life
Sensor will not protrude from wall more than 3/8” and will have a color coordinated matching lens
Sensor shall feature a walk-through mode, where lights turn off three minutes after the area is initially occupied if no motion is detected after the first 30 seconds, set by DIP switch
Sensor shall cover up to 1,000 sq. ft. for walking motion, with a field view of 180 degree
Each sensing technology shall have a LED indicator that remains active at all times in order to verify detection within the area to be controlled

Ideal for use in:.

Small and executive offices
Small and medium conference rooms
Lunch rooms
ADA Compliant buildings
