Paradox AMD12M-P9U Indoor Dual-Technology Motion Detector (White / 902MHz NA)

The Paradox AMD12M-P9U (AMD12M) is an advanced indoor 2-way wireless dual-technology motion detector engineered for Paradox wireless security systems (including Magellan MG5050, MG5075, and EVO/Spectra via RTX3 receivers). By combining a high-precision passive infrared (PIR) sensor with a microwave Doppler radar module operating on the North American 902MHz frequency band, it effectively eliminates false alarms caused by air currents, thermal fluctuations, and sunlight reflections—making it ideal for challenging indoor environments like warehouses, offices, and residential spaces with severe draft or temperature shifts.

Key System Features & Functionality

• Dual-Technology Detection (PIR + Microwave): Requires both infrared heat signatures and microwave motion doppler detection to trigger an alarm, virtually eliminating false alarms from environmental factors.

• 902MHz 2-Way RF Transceiver: Transmits instant alarm signals, supervisory polling, and diagnostic status feedback directly to the Paradox main panel.

• Digital Auto-Pulse Signal Processing: Dynamically evaluates detection signals to distinguish genuine intruder movement from background ambient noise.

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

• Dual Anti-Tamper System: Protects against unauthorized opening of the sensor enclosure or removal from the wall mounting surface.

• Pet Immunity Support: Integrated optics and digital processing help reject false triggers caused by small domestic animals.
