Wattstopper Occupancy Ceiling Sensor Ut-355-3-W Ultrasonic Line Voltage 360 Degree 120/230/277 Vacancy; White

Wattstopper Occupancy Ceiling Sensor Ut-355-3-W Ultrasonic Line Voltage 360 Degree 120/230/277 Vacancy; White - The UT-355 is factory set for a 20 minute time delay, ideal for both energy savings and user satisfaction in most applications. Installers can quickly select other fixed time delays (5, 10, 15 or 30 minutes) via DIP switches. Fixed time delays eliminate the occupant dissatisfaction associated with an automatically adjusted time delay option, and reduce callbacks. Walk-through mode may be enabled for added energy savings in spaces with frequent transient traffic. Advanced control logic based on RISC micro controller provides: Advanced signal processing to eliminate false triggers and provide immunity to RFI and EMI. Walk-through mode to turn lights off three minutes after the area is initially occupied. Zero crossing for long relay life. LED indicated occupancy detection. Coverage 500-2,000 square feet. DIP switch simplifies sensor adjustments.
