Motion detector PYRONIX KX15DT1 dual-technology Microwave + PIR detector KX15DT1

PYRONIX KX15DT1 dual-technology motion detector combines microwave and passive infrared (PIR) sensing to provide reliable indoor motion detection. The device monitors a defined coverage area and activates an alarm output only when both microwave and PIR sensors register movement, reducing the likelihood of false alarms caused by pets, air currents or minor temperature changes. Designed for residential and commercial installations, this detector includes tamper protection and adjustable settings to match different environments.

Advantages

The dual-technology design improves detection accuracy by requiring confirmation from both microwave and PIR sensors before triggering an alarm. Indoor mounting and adjustable sensitivity settings allow the detector to be tuned for different room sizes and layouts. Tamper protection and compatibility with standard alarm control panels make the unit suitable for integration into existing security systems. The detector’s configuration options help balance between detection range and false alarm immunity.

Suitable for

• Residential rooms and hallways where reduced false alarms are required
• Small to medium commercial premises such as offices and retail areas
• Integration with wired alarm control panels in security installations
• Indoor protection in areas with variable temperature or air movement

Key specifications

• Detection principle: dual-technology (microwave + PIR)
• Coverage: designed for standard indoor coverage zones
• Sensitivity: adjustable settings to suit installation environment
• Alarm output: requires both sensors to detect movement before activation
• Tamper protection: built-in anti-tamper mechanism
• Mounting: indoor wall mounting with installation adjustments

How to use

Install the detector on an indoor wall at the manufacturer-recommended height and orientation to ensure correct coverage of the protected area. Configure sensitivity and detection parameters to match the room size, expected traffic, and presence of pets or HVAC airflow. Connect the detector to the alarm control panel following wiring diagrams and safety procedures, and test detection across the coverage zone to confirm reliable operation. Adjust settings if necessary to minimize false alarms while maintaining needed sensitivity.

Usage recommendations

Position the detector away from direct drafts, heating sources and windows to reduce false triggers. When installing in spaces with pets, lower sensitivity or adjust coverage to avoid routine pet movement. Perform periodic functional tests and visual inspections to ensure sensors and tamper mechanisms operate correctly.
