Description
- Zero-crossing for long relay life.
- Ultrasonic diffusion technology spreads coverage to a wider area.
- DIP switch simplifies sensor adjustments.
- LEDs indicate occupancy detection.
- Uses existing line voltage wiring and doesn’t require a power pack.
- Six occupancy logic options give users the ability to customize control to meet application needs.
- Sensor coverage tested to NEMA Guide Publication WD7-2000.
The DT-355 is line voltage and operates on a single phase at 120, 230, 277 or 347 VAC. The sensor turns lighting on when both PIR and ultrasonic technologies detect occupancy. PIR technology senses the difference between infrared energy from a human body in motion and the background space. Ultrasonic technology uses high frequency (40kHz) ultrasound to sense motion within the space. Once lighting is on, detection by either technology holds lighting on. When no occupancy is detected for the length of the time delay, lighting turns off. The DT-355 can also be set so that only one technology is needed to trigger or both technologies are needed to hold lighting on.
