C&K DUAL Technology DT7435 Motion Sensor
K-Band Technology
SPEC SHEET PDF
The fully-featured DT-7435 motion sensor achieves reliable protection
with improved false alarm immunity through DualCore™ signal processing. K-band
microwave technology and Uniform Sensitivity Optics ensure optimum performance
Reliable 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 DT-7435 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 DT-7435 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 DT-7435 consistent coverage throughout the protected area.
Digital Adaptive Microwave Thresholds
The DT-7435 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.
