Designed for tough, commercial environments, the DT7450 Motion
Sensor achieves reliable protection with improved false alarm immunity through
DualCore™ signal processing. Optimum performance is achieved using K-Band
microwave technology and Uniform Sensitivity Optics. The DT7450-MIC is a fully featured DualTec with integrated microphone, for
listen in capabilities.
 Features
Advanced DualCore Signal Processing
DualCore
signal processing analyzes PIR and microwave signals through the DT7450’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 bidirectional
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
DT7450 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
DT7450 consistent coverage throughout the protected area.
Digital Adaptive Microwave Thresholds
The
DT7450 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 DT7450 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.
DT7450-MIC Only:
Integrated microphone for
use with most 2 way voice systems that accept a remote microphone input
compatible with Vista UVS, DSC, Apex Destiny 2 way voice
systems. |
