The next major OS Malevich update allows covering office centres with underground parking lots, sectional metal hangars, and warehouse complexes of several large buildings with a single Ajax system. Once the operating system is updated, ReX 2 will be able to connect to a hub both via radio communication and via Ethernet — using the wire as a single or second communication channel.


ReX 2 works as an extra intelligent control panel: it connects devices into an autonomous group and takes over control at the right time. Thanks to automatic adjustment of signal strength and frame synchronization, any number of system devices can be connected to ReX 2 — the reliability of communication will not be affected by this. If, for some reason, radio communication with the hub is interrupted, ReX 2 will receive an alarm from a sensor and activate a configured siren to draw attention to the incident and deter the burglar.

ReX 2 connection and configuration process saves the installation engineer time. To add a range extender to a system, simply scan a QR-code with the Ajax app and assign it a name and a room. The device is also configured in real time in the app. If necessary, ReX 2 can be disabled or reconfigured without site visits.
