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.

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 WS-250 PIR WALL SWITCH OCC SENSOR. This is the passive infrared wall switch occupancy sensor. The WS-250 Passive Infrared (PIR) Wall Switch Sensor turns lighting on and off based on occupancy and ambient light level. It replaces existing wall switches and fits behind a standard decorator wall plate.

The WS-250 utilizes advanced PIR technology to detect occupancy. Detection occurs when the WS-250 senses the difference between infrared energy from a human body in motion and the background space. Lighting automatically turns on when occupancy is detected. After a user-specified length of time when no occupancy is detected, lighting automatically switches off. The sensor can also be used with line voltage switches for multi-level lighting.

Features

• Pulse Count Processing eliminates false offs without
reducing sensitivity
• Detection Signature Processing eliminates false triggers;
provides immunity to RFI and EMI
• Zero crossing circuitry reduces stress on the relay and
results in increased sensor life
• Time delay adjustment from 30 seconds up to 30 minutes
• Adjustable unit sensitivity from 20% to 100%
• Light level sensor holds lights off when ambient lighting is
above the preset level
• Custom two-tier Fresnel lens enhances detection at the
desktop level
• Sensor coverage tested to NEMA Guide Publication WD 7-2000
• Patented voltage drop protection
• For safety, there is no leakage to load in the off mode and
sensor is safety grounded
• LED indicates occupancy detection
• Compatible with decorator wall plates
• BAA/TAA-compliant models available
