Designed for high security installations
where masking is a concern, the DT-7550C
motion sensor combines DualCore signal
processing with MaskAlert anti-mask
technology to achieve reliable commercial performance.
Features
- Superior Anti-Mask Protection
The DUAL TEC DT-7550C provides superior protection for
high security installations and other applications where
masking is a concern. MaskAlert™ technology detects
intentional as well as accidental masks or blocks.
Through a combination of PIR and microwave signal
processing, MaskAlert quickly detects the presence of a
wide variety of masking materials. 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 DT-7550C’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 DT-7550C 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 blend 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.
