Paradox 476PET-P2C Pro+ Hardwired Pet-Immune PIR Motion Detector (18kg / 40lb Pet Immunity)

The Paradox 476PET-P2C (Pro+ 476PET) is an official hardwired passive infrared (PIR) motion detector engineered for residential and commercial security systems. Designed specifically to eliminate false alarms caused by house pets, it features advanced optical filtering and Auto Pulse Signal Processing (APSP) that effectively ignores domestic animals weighing up to 18 kg (40 lbs). Built with high EMI and RFI shielding, Automatic Temperature Compensation, and a silent solid-state relay output, it delivers rock-solid perimeter detection without compromise.

Key System Features & Functionality

• Pet Immunity up to 18 kg (40 lbs): Specialized single-optic lens array and signal discrimination algorithms ignore dogs, cats, and small pets.

• Auto Pulse Signal Processing (APSP): Automatically converts motion signals into pulse sequences to distinguish genuine human intrusion from ambient thermal interference.

• High EMI & RFI Immunity: Metal shielding and internal noise suppression filters protect detection logic against cell phones, wireless signals, and electrical lines.

• Automatic Temperature Compensation: Adjusts PIR sensor sensitivity dynamically as ambient room temperatures change to maintain uniform coverage.

• Silent Solid-State Relay: Long-life NC solid-state relay output ensures quiet switching operation without mechanical wear.

• Cover Tamper Switch: Front enclosure tamper contact alerts the main alarm control panel immediately if the detector cover is opened.
