Installation & Operation
The UT-305-3 mounts on ceiling, tile, or surface at 8-10 ft height for optimal 360° ultrasonic coverage. The 40 kHz ultrasonic sensor detects motion within 2000 sq ft (10 x 66 ft, 46 x 46 ft sensing range). Lights turn on automatically when occupancy is detected and off after the adjustable delay (30 seconds to 30 minutes). Adjustable sensitivity (0-100%) prevents false triggers while ensuring reliable activation. Walk-through mode increases savings for spaces with brief occupancy. The ultrasonic detection LED indicator provides visual confirmation during setup. Operates with BZ Power Packs at 24VDC in dry locations at 32°F to 131°F (0°C to 55°C). Note: BZ Power Pack required for operation (sold separately).
Compatible Products
- BZ Power Packs: Compatible with BZ-150 Power Pack for automatic or manual-on operation (required, sold separately)
- Wattstopper Sensors: Coordinate with other Wattstopper occupancy sensors for comprehensive coverage

Frequently Asked Questions
What is the difference between an occupancy sensor and a vacancy sensor?
What is the difference between an occupancy sensor and a vacancy sensor?
Motion sensor switches utilize infrared radiation to monitor their surroundings. They emit energy forms such as light, microwaves, or sound to detect changes caused by movement. Most systems used in lighting and security are passive, meaning they primarily detect the infrared energy emitted by warm objects like human bodies.
Are occupancy sensors compatible with LED bulbs?
Are occupancy sensors compatible with LED bulbs?
Occupancy sensors and vacancy sensors are both used for detecting presence in a room, but they operate differently. Occupancy sensors automatically turn on the lights when someone enters a room and turn them off when no presence is detected after a set period. In contrast, vacancy sensors require someone to manually turn on the lights, but will automatically turn them off when the room is empty.
Do these sensors require a neutral wire?
Do these sensors require a neutral wire?
The primary distinction between a motion sensor light switch and a traditional light switch lies in their methods of activation. A traditional light switch requires manual operation to turn the lights on or off. Conversely, an occupancy sensor automatically activates the lights when someone enters the room and turns them off when it no longer detects any presence.
Can an occupancy sensor be used in a bathroom?
Can an occupancy sensor be used in a bathroom?
Occupancy sensors are designed to detect the presence of individuals or animals in a space and activate the lights accordingly, which can be combined with daylight sensors to enhance energy efficiency. On the other hand, daylight sensors adjust the lighting based on the natural light available, reducing the use of artificial lighting when not necessary.
Why do the lights turn off while I’m still in the room?
Why do the lights turn off while I’m still in the room?
Yes! Most motion sensors have adjustable sensitivity settings. This allows you to fine-tune the device to prevent false triggers or increase responsiveness in larger spaces.
