Ajax Superior MotionProtect Plus Fibra

Ajax Superior MotionProtect Plus Fibra — Wired PIR + Microwave Motion Detector

The Ajax Superior MotionProtect Plus Fibra is a wired indoor motion detector that pairs a PIR sensor with a K-band microwave sensor. The microwave channel confirms PIR detections, filtering out false alarms from heaters, air-conditioning drafts and sunlight, while the Fibra bus carries power and encrypted data up to 2,000 m from the hub over standard Cat5.

Key Features

• Dual technology: PIR sensor verified by a K-band microwave sensor
• Detection range up to 12 m
• Pet immunity: ignores animals up to 20 kg and 50 cm tall at 2.4 m mounting height
• Three sensitivity levels selectable in the Ajax app
• Fibra wired protocol: encrypted, two-way, up to 2,000 m using U/UTP Cat5 (beam topology)
• Powered from the hub over the Fibra line — no separate PSU per detector
• Remote configuration and testing from Ajax PRO apps
• SmartBracket mounting for quick installation; indoor use

Where it fits

Wired and hybrid Ajax installations in offices, shops, warehouses and homes with pets, especially rooms with heating, ducted air or glazing where a single-technology PIR is prone to false alarms.
