 Motion Sensor
The DT7235T DUAL TEC® Motion Sensor provides reliable protection with pet immunity for up to 100 lbs. in a simple
installation configuration that requires no adjustments. Optimum performance is achieved using K-Band microwave
technology and Uniform Sensitivity Optics.
FeaturesReliable Detection with 100 lb. Animal Immunity
By combining Uniform Sensitivity Optics with the advantages offered
by K-Band technology, the DT7235T sensor gives installers the best of both
worlds — quality detection and the ability to ignore pets or other animals up to
100 lbs.
Fast and Simple Installation without Adjustments
No
adjustments are necessary. Installers simply mount the unit at the recommended
height, conduct a brief walk-test and the sensor is ready. A highly visible,
single colored LED helps the installer easily identify range from any distance
or angle within the pattern.
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.
Patented False Alarm Prevention Features
The DT7235T
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 the patented adaptive
microwave threshold circuit automatically adjusts for room disturbances.
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.
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 DT7235T consistent
coverage throughout the protected area.
Microwave Adaptive Threshold
Using a patented microwave
adaption circuit, the DT7235T automatically 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.
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.
Microwave Supervision
Independent circuitry supervises
the microwave against failure.
Effective in Hot or Cold Environments
The DT7235T
operates effectively in harsh environments (14° to 131° F / -10° to 55° C).
Temperature compensation adjusts processing for improved detection and false
alarm immunity. |
