Paradox PMD75N-K9A Wireless Digital Dual-Optic PIR Motion Detector with Pet Immunity (433MHz)

The Paradox PMD75N-K9A is an enterprise-grade, high-performance wireless passive infrared (PIR) motion detector engineered specifically for indoor residential and commercial environments where large domestic animals are present. Featuring Paradox's patented Dual Optical Filtering System and two independent dual-element infrared sensors, the PMD75N-K9A delivers true pet immunity for animals weighing up to 40 kg (90 lbs), drastically reducing false alarms while ensuring rapid detection of human intruders.

Communicating over a reliable 433 MHz wireless RF channel, the PMD75N-K9A uses Digital Auto Pulse Signal Processing (APSP) and automated digital temperature compensation to maintain stable, precise detection performance across variable thermal conditions. Fully compatible with Paradox Magellan MG series consoles and Spectra SP / EVO control panels via wireless expansion modules (RTX3 / RX1), it incorporates dual-tamper detection (cover open and wall detachment) along with smart battery-saving features. Supplied with factory power cells included ("K9A" package variant), it offers a complete, ready-to-deploy solution for security integrators.

Key System Features & Functionality

• Dual Optical Detection System: Combines two independent dual-element PIR sensors and advanced optical lenses to analyze human movement versus animal profiles.

• True 40 kg (90 lbs) Pet Immunity: High-performance pet discrimination algorithms guarantee reliable rejection of signals caused by large dogs, multiple small pets, and domestic animals.

• Digital Auto Pulse Signal Processing (APSP): Advanced digital signal evaluation adjusts response thresholds to eliminate environmental noise and RF interference.

• Broad Coverage Pattern: Provides 11 m x 11 m (35 ft x 35 ft) area protection with a 110° center viewing angle and zero-dead-zone creep optics.

• Dual Anti-Tamper Protection: Built-in dual tamper switches trigger immediate panel alerts if the front cover is opened or if the detector is removed from the wall.

• Paradox Wireless Integration: Fully compatible with Magellan MG5000, MG5050, MG6250 panels, and RTX3 / RX1 wireless expansion modules operating on 433 MHz.
