The Ajax Superior MotionProtect Plus Jeweller in black is a dual-technology wireless motion detector designed to protect indoor environments with complex thermal conditions. Belonging to the professional Superior product line, it holds top European security certifications including EN 50131 Grade 2 (specific EN 50131-2-4 standard for combined detectors), NFA2P, INCERT, and PD 6662:2017.
In addition to a high-precision passive infrared (PIR) sensor driven by the SmartDetect software algorithm, MotionProtect Plus incorporates a 24 GHz K-band microwave sensor. Whenever motion is detected by the PIR sensor, the device performs an additional radio-frequency scan to verify the intrusion, effectively filtering out false alarms caused by air conditioning drafts, moving curtains, fireplaces, or solar glare. When installed at the recommended height of 2.4 meters, it reliably ignores pets weighing up to 20 kg and under 50 cm in height.
#### Encrypted Wireless Communication and Long Battery Life
Wireless communication with the control panel is powered by the proprietary Jeweller encrypted two-way protocol, providing an operational range of up to 1,200 meters in open space with frequency hopping against jamming. Supplied ready to install with the SmartBracket mounting panel featuring a security holding screw, anti-tamper switch, and a pre-installed CR123A battery offering up to 5 years of autonomous operation.
