 DUAL Technology Motion Sensor
K-Band Technology
The fully-featured DUAL TEC® DT7435 motion sensor achieves reliable protection and improved false alarm immunity
through DualCore™ signal processing. K-Band microwave technology and Uniform Sensitivity Optics ensure optimum
performance.
 FeaturesReliable Detection with 100 lb. Animal Immunity
The combination of DualCore signal processing, Uniform Sensitivity
Optics and K-Band technology, provides installers with both quality detection
and the ability to ignore pets or other animals up to 100 lbs.
Advanced DualCore Signal Processing
DualCore signal
processing analyzes PIR and microwave signals through the microcontroller. It
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 DT7435
protects 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.
Immune to Pets up to 100 lbs.
Backed by extensive design
and field experience with pet immunity, the DT7435 delivers robust pet immunity
without impacting detection performance.
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 DT7435 consistent coverage
throughout the protected area.
Digital Adaptive Microwave Thresholds
The DT7435
digitally adjusts its thresholds to account for room disturbances such as
ceiling fans and other repetitive moving objects which are not intrusion events.
The result is 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 60Hz or 50Hz
via DIP switch.
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.
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.
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.
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.
