Paradox PMD5M-L9U Indoor Miniature Wireless Motion Detector (White / 902MHz NA)

The Paradox PMD5M-L9U (PMD5M) is an official ultra-compact, wireless dual-element passive infrared (PIR) motion detector engineered for Paradox wireless security systems (including Magellan MG5050, MG5075, and EVO/Spectra via RTX3 receivers). Featuring an ultra-slim, modern enclosure, it delivers reliable indoor volumetric coverage operating on the North American 902MHz frequency band. Equipped with digital auto-pulse signal processing, automatic temperature compensation, and an integrated anti-tamper switch, it ensures rapid intrusion detection with maximum false-alarm immunity.

• Ultra-Miniature Design: Unobtrusive, modern white housing blends seamlessly into residential and commercial interiors.

• Dual-Element PIR Sensor: Delivers 10m X 10m (5ft X 35f) volumetric coverage with an 88.5° viewing angle.

• Digital Auto-Pulse Signal Processing: Automatically adjusts detection thresholds based on movement signal strength to eliminate false alarms from environmental noise.

• Automatic Temperature Compensation: Adjusts PIR sensitivity dynamically as room temperatures approach human body temperature.

• Dual Anti-Tamper Switch: Detects unauthorized opening of the detector casing or removal from the mounting surface.

• Energy-Efficient Battery Operation: Powered by long-lasting lithium batteries with integrated power-save modes for multi-year lifespan.
