Honeywell DT7550C DUAL Technology Motion Sensor: K-Band Technology

Description
Designed for high security commercial installations where masking is a concern, Honeywell’s DUAL TEC® DT7550C Motion Sensor combines DualCore™ signal processing with MaskAlert™ anti-mask technology to ensure superior performance.

Through a combination of PIR and microwave signal processing, MaskAlert technology quickly detects intentional and accidental masks or blocks. The sensor sends a trouble signal whenever it encounters mask conditions. Power-up anti-mask detects mask conditions at start-up to reduce sensor security breaches during installation, servicing, and power outages.

Features

• Advanced DualCore Signal Processing
  DualCore signal processing analyzes PIR and microwave signals through the DT7550’s microcontroller. DualCore processing supports a multitude of advanced functions, including concurrent diagnostics, digital fluorescent light interference filter, digital adaptive microwave threshold, adaptive baselines, and bi-directional temperature compensation.
• Superb Detection Through K-Band Technology
  K-Band microwave technology delivers sharp detection without holes or weak spots. The custom made source offers pattern shaping to fill the protected area with a broad, balloon-shaped pattern which matches the PIR pattern. It also offers pattern containment to reduce the penetration of microwave energy through walls.
• Enhanced False Alarm Prevention Features
  The DT7550 offers more than the standard features that protect against false alarms due to RF signals, electrostatic discharge, and electrical overstress. The patented black bug guard improves white light immunity and digital adaptive microwave thresholds automatically adjust for room disturbances.
• Self-Testing for Consistently Reliable Operation
  Concurrent diagnostics assure optimum performance and reliability. Self-testing is performed upon power-up and at least once every hour on the PIR, microwave, PCB circuitry and temperature compensation circuitry.
• Sturdy, Attractive Housing
  The sleek, sturdy housing fits into a variety of building styles and blends with any room decor. ABS plastic is used for shock and impact protection. The housing offers a convenient wiring channel, knockouts for mounting and wiring, and easy access to wiring terminals.
• DualCore Signal Processing
  PIR and microwave signals are analyzed in the microcontroller in multiple domains, including amplitude, time, frequency and duration to provide superior false alarm immunity without compromising detection. DualCore processing not only supports alarm functions, but also advanced temperature compensation, diagnostics, and false alarm features.
• Uniform Sensitivity Optics
  The custom-designed Fresnel lens provides the same sensitivity for human targets at the edge of the pattern as exists directly in front of the sensor, giving the DT7550 consistent coverage throughout the protected area.
• Digital Adaptive Microwave Thresholds
  The DT7550 digitally adjusts its thresholds to account for room disturbances such as ceiling fans and other repetitive moving objects which are not an intrusion event. The result – excellent false alarm immunity even in “active” rooms.
• Digital Fluorescent Light Interference Filter
  Potential false alarms due to fluorescent lights are eliminated with a digital filter with infinite rejection. Frequency of the filter is selectable between 60 Hz or 50 Hz via DIP switch.
• Patented Mirror Look Down
  Provides better coverage up close with multiple zones in the look down area.
• Global Compliance
  Our designs meet many of the world’s motion detector standards, including the new EN50131-1. And with K-band microwave, it can be used in virtually every market all around the globe.
• White Light Immunity
  A patented black bug guard reduces false alarms by providing 6,500 lux of white light immunity. This helps reduce false alarm problems caused by lights, flashlights or reflective objects.
• Flexible Mountings:
  The DT7550 family mounts on walls, in corners or on ceilings with the SMB10 family of swivel brackets.
• Concurrent Diagnostics
  Optimum performance and reliability are assured through comprehensive diagnostics that do not compromise detection during testing. In addition to performing a full self-test upon power-up, microwave supervision is performed continuously; PIR supervision is performed once every hour. Temperature compensation is monitored and updated every 30 seconds.
