Paradox PMD75N-PHY Wireless Digital Dual-Optic High-Performance PIR Motion Detector with Pet Immunity (Without Battery)

The Paradox PMD75N-PHY is an enterprise-grade, high-performance wireless passive infrared (PIR) motion detector engineered specifically for harsh 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-PHY delivers true pet immunity for animals weighing up to 40 kg (90 lbs), drastically reducing nuisance alarms while ensuring rapid detection of human intruders.

Communicating over a reliable 433 MHz wireless RF channel, the PMD75N-PHY 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. This specific "PHY" package variant is supplied without AAA batteries, providing integrators with a cost-effective stock option for custom battery choice upon installation.

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 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.

• Integrator Pack Variant (PHY): Supplied without AAA power cells, allowing technicians flexibility in selecting high-grade battery chemistry during deployment.
