The DT-300 Series Dual Technology Ceiling Sensors combine the benefits of passive infrared (PIR) and ultrasonic technologies to detect occupancy. Sensors have a flat; unobtrusive appearance and provide 360 degrees of coverage.

• Advanced control logic based on RISC micro-controller
• Provides: – Detection Signature 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
• Available with built-in light level sensor featuring simple; one-step setup
• Patented ultrasonic diffusion technology spreads coverage to a wider area
• LEDs indicate occupancy detection
• Sensors work with low-voltage momentary switches to provide manual control
• Uses plug terminal wiring system for quick and easy installation
• Eight occupancy logic options provide the ability to customize control to meet application needs
• Available with isolated relay for integration with BAS or HVAC
• BAA/TAA-compliant models available
• Sensor coverage tested to NEMA Guide Publication WD 7-2000
