Ajax MotionProtect Plus Fibra Black Wired PIR + Microwave Motion Detector

Ajax MotionProtect Plus Fibra Black - Wired Dual-Technology Motion Detector

The Ajax MotionProtect Plus Fibra in black is a hardwired indoor motion sensor built for professional intrusion detection systems. It pairs a passive infrared sensor with a K-band microwave sensor that only switches on once the PIR stage registers movement, giving installers a detector that resists false alarms from heaters, air conditioners, drafts and sunlight while still reacting quickly to a genuine intruder. It connects to an Ajax hub over the secure Fibra wired protocol, combining the reliability of a cabled system with the flexible configuration and instant app notifications Ajax is known for.

Key Features

• Dual detection technology - PIR sensor plus a K-band microwave sensor that activates only when motion is first detected, filtering out thermal false triggers
• Long detection range - recognises movement at distances of up to 12 metres when mounted at the recommended 2.4 metre height
• Pet-friendly design - ignores animals up to 20 kilograms in weight and 50 centimetres in height
• Secure Fibra wired connection - supports cable runs of up to 2,000 metres using standard U/UTP cat.5 twisted pair
• Temperature compensation - maintains accurate detection in environments with temperatures close to human body heat
• Tamper protection - triggers an alert if the unit is pried from the wall or removed from its SmartBracket mounting panel
• Low power design - draws minimal power from the Fibra line, helping installers plan larger wired systems
• Remote configuration - sensitivity and settings can be adjusted from the Ajax app without a return site visit
• Sleek black housing - discreet, modern enclosure that blends into most interior fit-outs

Where It Fits in a Security System

This detector is designed for indoor perimeter and room protection in homes, offices, retail spaces and other commercial premises that use a hardwired Ajax security backbone. It suits installers who need the tamper resistance and cable-run distances of a wired system, while still wanting the fast setup, app-based diagnostics and low false-alarm rate typically associated with Ajax's wireless range. It connects to compatible Ajax hub hardware as part of a broader Fibra-based intrusion detection installation.

Frequently Asked Questions

Does this detector work wirelessly?
No. It is a wired device that communicates with an Ajax hub using the Fibra cabled protocol rather than radio signal, which is why it supports very long cable runs.

Will it false-alarm on my pet?
The sensor is designed to ignore animals up to roughly 20 kilograms and 50 centimetres tall, making it suitable for most households with small to medium pets.

What hub does it need?
It requires an Ajax hub that supports the Fibra wired line; check compatibility with your specific hub model before installation.
