WattStopper®, DT-355, Ceiling Mount Occupancy Sensor, Dual Technology Line Voltage Low Profile, Series: DT Series, 24 VAC/VDC, 0 to 1500 W Power, Passive Infrared/Ultrasonic Sensor, 1000 sq-ft Coverage, 360 deg Viewing, 5 to 30 min Time Delay, LED/Tungsten Lamp, 40 kHz Response, Flying Lead Connection, Automatic On/Automatic Off Control Output, Ceiling/Swivel Bracket Mounting, 35 deg C, Plastic, White, 4.5 in Dia x 1.02 in D Dimensions
PIR technology senses occupancy by detecting the difference between heat emitted from the human body in motion and the background space. Relying on a clear line-of sight view, passive infrared sensors make 100% coverage cut off possible. These sensors utilize a unique fresnel lens which divides the coverage area into zone, enhancing detection of small movement. Using the doppler principle, ultrasonic sensors work by bouncing ultrasonic sound waves off objects in an area and measuring the time it takes for the waves to return. Movement by a person in the area causes the sound waves to return at a changed frequency, resulting in a doppler shift and occupancy detection.
- 95% relative humidity, non-condensing, for indoor use only environmental conditions
- Dual technology occupancy sensor combines the benefits of passive infrared (PIR) and ultrasonic technologies
- The sensor mounts on the ceiling with a flat, low profile appearance and provides 360 deg of coverage
- Detection signature analysis eliminates false triggers and provides immunity to RFI and EMI
- Walk through mode turns lights off 3 min after the area is initially occupied - ideal for brief visits such as mail delivery
- Built-in light level sensor featuring simple, one step setup
- Zero crossing for long relay life
- 1 x 108 operating cycle
- Ultrasonic diffusion technology spreads coverage to a wider area (patent pending)
- Dip switch simplifies sensor adjustments
- LEDs indicate occupancy detection
- Uses existing line voltage wiring and doesnt require a power pack
- Six occupancy logic options give users the ability to customize control to meet application needs
- Ballast load type
- Architecturally appealing low profile appearance
- Auto set automatically selects optimal settings for each space
- Walk through mode increases savings potential
- Ultrasonic diffusers give more comprehensive coverage
- Terminal wiring for quick and easy installation
