 DUAL Technology Motion Sensor
K-Band Technology
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.
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. |
