Paradox PMD85-K9A Wireless Outdoor Digital Dual-Optic PIR Motion Detector with Pet Immunity (433MHz)

The Paradox PMD85-K9A is a heavy-duty, commercial-grade wireless outdoor passive infrared (PIR) motion detector engineered specifically to withstand challenging external weather conditions while providing precise intrusion detection. Protected by an IP45-rated weatherproof casing constructed from high-impact, UV-resistant materials and a rubber-sealed gasket, the PMD85-K9A ensures reliable year-round performance across residential perimeters, driveways, yards, and commercial storage areas.

Utilizing Paradox's patented Dual Optical Filtering System with two independent dual-element sensors, the PMD85-K9A offers true pet immunity for domestic animals weighing up to 40 kg (90 lbs). This dual-optic geometry analyzes detection signals dynamically via Digital Auto Pulse Signal Processing (APSP), eliminating false triggers caused by pets, birds, wind-blown foliage, or sudden ambient sunlight shifts. Operating at a stable 433 MHz RF frequency, it features multi-level sensitivity adjustment, dual anti-tamper protection, and continuous supervisory check-ins. Supplied complete with factory batteries included ("K9A" variant), it delivers a turnkey wireless outdoor security solution.

Key System Features & Functionality

• Dual Optical Detection System: Combines two independent dual-element infrared sensors to analyze human targets versus environmental movement and animal activity.

• True 40 kg (90 lbs) Pet Immunity: High-performance optical filtering and signal processing eliminate false alarms caused by large dogs, roaming pets, and outdoor wildlife.

• IP45 Weatherproof & UV Protected: Hermetically sealed housing with silicone rubber gaskets protects internal electronics from water spray, dust, ice, and direct UV radiation.

• Digital Auto Pulse Signal Processing (APSP): Advanced signal analysis dynamically adjusts response thresholds based on environmental temperature variations and RF noise.

• 433 MHz Long-Range Wireless Transmission: Delivers reliable wireless communication up to 35 m (115 ft) with Magellan control panels and up to 70 m (230 ft) with RTX3 expansion modules.

• Ready-to-Deploy Package (K9A): Factory-supplied with high-capacity AA batteries for fast field installation by security technicians.
