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.

Features

• Advanced control logic based on RISC microcontroller
provides:
– Advanced Signal Processing eliminates false triggers and
provides immunity to RFI and EMI
– Walk-through mode turns lights off three minutes after
the area is initially occupied – ideal for brief visits such as
mail delivery
• LED indicates occupancy detection
• Coverage 500-2,000 square feet
• Available with isolated relay for integration with BAS or HVAC
• DIP switch simplifies sensor adjustments
• Patented ultrasonic diffusion technology spreads coverage to
a wider area
• UT-300 Series Sensors work with low-voltage momentary
switches for manual control
• Clip mounting system makes ceiling tile installation simple
• Uses plug terminal wiring system for quick and easy
installation
• BAA/TAA-compliant models available
• Sensor coverage tested to NEMA Guide Publication WD 7-2000

Specifications

• 24 VDC/VAC
• Time delays: 5, 10, 15, 20 or 30 minutes, Walk-through/
Test Modes
• Sensitivity adjustment: variable with trimpot
• Ultrasonic frequency: 40 kHz
• UT-300 contains isolated relay with N/O and N/C outputs;
rated for 1 Amp at 30 VDC/VAC
• Mounting options: ceiling tile; 4” square junction box with
double-gang mud ring
• Max. UT-300s per power pack: B=2, BZ=3
Max. UT-305s per power pack: B=3, BZ=4
• Dimensions: 4.5” x 1” (114.3mm x 25.9mm) diameter x depth
• UL and cUL listed
• Five year warranty

The WattStopper DT-305 Ceiling Sensor combines the benefits of passive infrared (PIR) and ultrasonic technologies to detect occupancy and reduce false triggers. Sensors have a flat, unobtrusive appearance and provide 360 degrees of coverage. They easily mount to ceiling tiles or junction boxes. Ideal applications include classrooms, open office spaces, large offices, and computer rooms.

These WattStopper sensors use power packs for auto-on/off or low voltage switches for manual-on (both sold separately). In addition, the DT-300 family of sensors easily field modify to trigger lights on when either technology or both detect occupancy, or to require both technologies to hold lighting on. Once lights are on, detection by either technology holds them on. Lights turn off when occupancy is not detected for the length of the specified time delay.

• Sensors work with low-voltage momentary switches to provide manual control
• Patented ultrasonic diffusion technology spreads coverage to a wider area
• LEDs indicate occupancy detection
• Uses plug terminal wiring system for quick and easy
• Eight occupancy logic options provide the ability to customize
• Available with isolated relay for integration with BAS or HVAC
• BAA/TAA-compliant models available

PIR vs. Ultrasonic

PIR technology senses motion via a change in infrared energy within the controlled area. Ultrasonic uses 40KHz high frequency ultrasound.

This is the passive infrared ceiling sensor. Wattstopper’s WPIR Sensor is a versatile ceiling-mount sensor that utilizes the latest passive infrared (PIR) technology to turn lights on and off based on occupancy. The WPIR controls lighting in a wide variety of applications, but is especially adept at controlling small spaces with well-defined coverage.

The WPIR Ceiling Sensor utilizes the latest PIR technology to detect the difference between the infrared energy from a person in motion and the background space within the controlled area. When occupancy is detected, this 24 VDC sensor turns lighting or HVAC systems on through a Wattstopper power pack controlled through low voltage wiring. When occupants leave the area, lighting is switched off after the user-adjustable time delay has elapsed. Check out Wattstopper DLM products here.

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.
