Ajax Superior MotionProtect Plus Fibra White — Motion Detector with Microwave Sensor

Professional Ajax Superior MotionProtect Plus Fibra White Wired Dual-Technology Motion Detector with NFA2P Certification

The Ajax Superior MotionProtect Plus Fibra in white is a high-precision wired motion detector engineered for indoor protection in environments with complex thermal interference (such as air-conditioned rooms, areas near fireplaces, drafts, or large sunlit windows). In addition to a passive infrared (PIR) sensor, the device integrates an auxiliary K-band microwave sensor. When the PIR sensor detects a thermal variation in the room, the detector performs a radio-frequency scan to confirm whether real human movement is occurring, effectively filtering out false alarms caused by circulating air currents.

The detector includes smart pet immunity, ignoring pets weighing up to 20 kg and up to 50 cm in height when mounted at the recommended height of 2.4 meters. It meets strict European compliance standards, holding EN 50131 Grade 2, NFA2P, and PD 6662:2017 certifications.

#### Physical Anti-Tamper Protection and Advanced Fibra Bus Technology

The housing is equipped with a physical anti-tamper switch that immediately alerts the hub upon any attempt to open the cover or detach the device from its SmartBracket panel. It also features an integrated ambient temperature sensor for diagnostic monitoring and automatic thermal compensation.

Data transmission and power supply operate through the Fibra proprietary wired bus protocol. This bus technology delivers instant bi-directional encrypted communication, bus short-circuit protection, and line support up to 2,000 meters.
