Guardian for doors, windows, and valuables
DoorProtect Fibra is designed to detect intrusion and burglary attempts, offering comprehensive coverage for doors, windows, skylights, and vaults. Equipped with two reed switches as opening sensors, the detector features protection against chattering in its operation. Two magnets of different sizes provide more mounting options. All in line with the Ajax user experience, ensuring quick and easy device installation.

High-end reed switches for reliable opening detection
DoorProtect Fibra features two durable reed switches, allowing the magnet to be positioned on either side of the detector (right or left). This flexibility provides installers with more options for wire routing, as the detector functions effectively irrespective of magnet placement. Housed in resilient plastic capsules, reed switches remain intact during transportation, even in case of drops.

Easy integration with third-party detectors
DoorProtect Fibra has terminals for connecting a third-party wired NC detector. This allows an installer to enhance system reliability with any NC detector, whether newly installed or already in place, such as motion, opening, or vibration detectors. For example, DoorProtect Fibra enables you to integrate an existing third-party3 opening detector into the system.

Use a detector as a doorbell
The Chime feature transforms the combination of an Ajax opening detector and siren into a shopkeeper's bell. When the system is disarmed, the siren notifies about door openings with one of four available short sound signals. PRO users can adjust the volume and assign different signals for separate entrances, making it easy to recognize whether someone entered through the main or a back door.

Unique wired technology
An Ajax system uses secure two-way communication based on Fibra proprietary protocol. It features encryption and device authentication to prevent sabotage, spoofing, and data theft. Fibra lines are versatile and support connecting different types of devices to one line: sirens, keypads, and detectors with photo verification.
