Product Description
Wired PIR detector for Ajax Fibra systems, built for installs where a hardwired detection layer is specified in place of RF.
Key specs
- Detection range: up to 12 m, 88.5° horizontal angle
- Signal processing: digital analysis of motion patterns to filter environmental interference and cut false alarms
- Pet immunity: animals up to 20 kg / 50 cm in height won't trigger the sensor
- Connection: Ajax Fibra wired protocol, encrypted, for fast signal transmission and interference resistance
- Tamper protection: anti-sabotage alert on case removal/opening
- Power: low consumption, designed for reliable long-term operation on a wired network
On the job
Placement should account for the 12 m / 88.5° coverage envelope when planning detector counts and overlap across a floor plan. Because it's wired into the Fibra bus rather than RF-paired, it suits sites where cable runs are already planned or where RF interference is a concern.
The pet immunity threshold (20 kg, 50 cm) is worth checking against the client's animals before specifying — it's a hard cutoff, not a general "pet-friendly" claim. Tamper protection covers removal or case-opening attempts, reporting back over the same wired Fibra link used for detection events.
This unit integrates with Ajax Fibra hubs and modules as part of a wired detection layer; confirm current hub/module compatibility for the specific Fibra system version on site before ordering.

Frequently Asked Questions
What is the detection range and angle of the MotionProtect Fibra?
Up to 12 metres with an 88.5° horizontal detection angle.
Will pets trigger false alarms?
The detector has pet immunity for animals up to 20 kg and 50 cm in height, reducing nuisance alerts in mixed-use premises.
Is this a wired or wireless detector?
It's wired, using Ajax's encrypted Fibra communication protocol rather than an RF connection.
Does it have tamper detection?
Yes, it includes tamper protection that alerts the system if the unit is removed or opened.
