This is the ultrasonic ceiling sensor. Wattstopper’s W Series Ultrasonic Ceiling Sensors are versatile motion detectors that control lighting in a wide variety of applications. W Series Sensors can be used individually or as part of an integrated system of Wattstopper lighting control products.

The 24 VDC W Series Sensors utilize advanced omni-directional, ultrasonic technology to sense occupancy. When movement is detected in a controlled area, the W Series Sensors will switch lights on via low-voltage wiring through to a Wattstopper power or auxiliary pack. Once the area is vacated and the user adjustable time delay (15 seconds to 15 minutes) has elapsed, lighting systems automatically switch off. Check out Wattstopper DLM products here.

Wattstopper UT-305-X ULTRASONIC CEILING SENSOR. This is the ultrasonic low voltage ceiling sensor. Wattstopper’s UT-300 Ultrasonic Ceiling Sensors automatically turn lighting on and off based on occupancy. The sensors mount on the ceiling with a flat, unobtrusive appearance and provides 360° coverage.

UT-300 Series Sensors operate on 24 VDC, VAC or halfwave rectified. They use 40 KHz high frequency ultrasound to sense occupancy and automatically turn lighting on. When no occupancy is detected for the length of the time delay, lighting automatically turns off. For manual-on operation, the units work with a low-voltage momentary switch.

Wattstopper WT-SERIES ULTRASONIC CEILING SENSOR. This is the ultrasonic ceiling sensor. Wattstopper’s WT Ultrasonic Ceiling Sensors utilize 32 KHz frequency ultrasonic technology to detect occupancy. The sensors are available in several models to control lighting in a wide variety of applications.

WT Sensors are 24 VDC and utilize advanced, omni-directional, ultrasonic technology. When movement is detected in a controlled area, it switches lighting on through a Wattstopper power or auxiliary pack. The sensor controls the power pack through low voltage wiring. Once the area is vacated and the time delay has elapsed, lighting systems automatically switch off.

Features

• ASP circuitry helps to eliminate false on
• Advanced, omni-directional, ultrasonic technology for
reliable occupancy detection
• Angled transmitter and receiver pairs help optimize
sensitivity while eliminating unwanted detection from ceiling
air movement
• Coverage ranges from 600 to 2200 square feet, and 90 linear
feet for hallways
• Isolated relay can interface with HVAC, EMS or an additional
lighting load
• DIP switch-adjustable time delay and sensitivity
• LED indicates occupancy detection
• BAA/TAA-compliant models available

Specifications

• Solid state, crystal-controlled (32.768 kHz ± 0.002%)
• Omni-directional transmission (360° coverage)
