Wired PIR Motion Sensor Ajax Superior CombiProtect Fibra — Wall-mounted, 12 m, White

Wired PIR Motion Sensor Ajax Superior CombiProtect Fibra is a wall-mounted indoor detector combining passive infrared motion sensing and acoustic glass break detection in a single compact white housing (110×65×50 mm). Designed for wired Fibra systems, the detector operates from DC power and provides reliable presence detection up to 12 m, with a detection angle of 88.5°. The device integrates Fibra two-way wired communication with encryption and authentication, supports centralized supervision, and is suitable for professional installations in homes and commercial premises.

Advantages

The detector merges motion and glass-break detection in one unit, reducing the number of devices required and simplifying wiring. A high-quality Excelitas PIR sensor and a Fresnel lens pattern improve discrimination between human movement, pets and thermal noise, while SmartDetect software and temperature compensation reduce false alarms. DualTone glass-break analysis registers both low-frequency impact and high-frequency ringing, increasing detection accuracy. Fibra wired communication provides secure, low-interference data exchange with minimal power consumption and centralized monitoring for continuous system supervision.

Suitable for

• Indoor perimeter and room intrusion detection in homes and apartments
• Office and retail spaces requiring combined motion and glass-break protection
• Commercial installations integrated into Fibra wired security systems
• Professional alarm system projects where centralized supervision and tamper control are required

How to use

Install the detector on a wall at the recommended height of 2.4 m with the lens perpendicular to the expected intrusion path to obtain accurate thermal diagrams and optimal pet immunity. Connect the device to the Fibra wired line and DC power according to the system wiring diagram; the detector supports integration with hubs and line-extension modules. Configure sensitivity levels and glass-break thresholds via the Ajax app, run a device test from the app to verify operation, and register the detector in the system for centralized monitoring and notifications.

Recommendations

For reliable performance, position the detector to avoid direct air flow from heaters or vents and away from large heat sources. Use the app to select an appropriate sensitivity level based on site conditions and pet presence, and follow professional installation guidelines for wiring and tamper protection to ensure continuous supervision and reduced false alarms.
