Feature
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.
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.
Kband Microwave Technology
Kband technology delivers sharp detection and superior false alarm immunity through pattern shaping and pattern containment. Pattern shaping fills the protected area with a broad, balloon shaped pattern which matches the PIR pattern. Because K-band is a higher frequency, the amount of microwave energy that penetrates walls is reduced, containing the pattern within the coverage area.
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-7225 consistent coverage throughout the protected area.
Microwave Adaptive Threshold Using a patented microwave adaption circuit, the DT-7225 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 DT7225 operates effectively in harsh environments (14° to 131C / -10° to 55C). Temperature compensation adjusts
processing for improved detection and false alarm immunity
