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.

Protection against sabotage and spoofing

Energy efficiency first

LineSupply with connected devices consumes no power from the hub. Fibra communication itself requires minimum power consumption and follows the TDMA principle. Each device has a short time frame to exchange data with a hub, and its communication module is inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.

Each LineSupply output line is power-independent, making the system even more reliable. The module is powered by 110–230 V~ mains and has a connector for a 12 V⎓ backup battery with a capacity from 7 to 18 A·h.

Data encryption

All data the system stores and transmits is protected by block encryption with a dynamic key. Encryption makes it extremely difficult to connect to the module with the intention of sabotage.

Communication failure detection

Communication failure detection

The device regularly exchanges data with the hub. With minimal polling interval settings (3 data packages and 12 seconds), it takes only 36 seconds to identify communication loss and notify the security company and users about the incident. Additionally, the hub is controlled by the Ajax Cloud server, so each element of the system is supervised.
