Optex QXI-DT Dual Tech Microwave Pir Outdoor Sensor

Product Description

The OPTEX QXI-DT is a wide-angle dual-technology microwave and passive infrared (PIR) outdoor sensor designed for perimeter detection and security applications. By combining microwave and PIR technologies, the QXI-DT reduces false alarms compared to single-technology detectors — both sensing layers must trigger before an alarm is generated. This makes it well-suited for outdoor environments where wind, temperature shifts, and moving foliage can cause nuisance trips in standard PIR-only units. Licensed security technicians and alarm installers are the primary trade installing this type of device.

The QXI-DT is intended for outdoor perimeter security installations, including commercial and residential properties where reliable motion detection is required in challenging environmental conditions. Its wide-angle coverage pattern allows installers to protect broader areas with fewer devices. Typical install scenarios include building exteriors, parking areas, entryways, and fence lines where a combination of detection technologies is preferred for accurate threat identification.

Key Features

• Dual-technology detection combining microwave and PIR for reduced false alarm rates
• Wide-angle coverage pattern suited for broad outdoor zones
• Designed for outdoor perimeter security applications
• Single-unit packaging for straightforward field deployment

Compatibility

Designed as an OEM-style outdoor dual-technology PIR and microwave motion sensor suitable for integration with standard commercial and residential security alarm systems.

Installation Notes

Installation is typically performed by licensed alarm or low-voltage security technicians in accordance with local electrical codes and manufacturer mounting guidelines. Power down or de-energize the alarm panel circuit before wiring the sensor. Mount at the manufacturer-recommended height and orientation to achieve the specified detection coverage pattern. Avoid aiming the sensor at reflective surfaces or high-traffic areas outside the intended detection zone to minimize nuisance alarms.
