## Summary description

Ajax REX Smart Home wireless range extender in white expands and stabilizes radio coverage for compatible Ajax security systems. It receives and retransmits device signals to improve connectivity in buildings with signal obstacles or large areas. Designed for indoor residential and commercial use, it supports automatic switching, remote configuration via the Ajax app, and reliable signal relay to reduce false disconnections.

## Long description

Ajax ReX Smart Home is a wireless radio range extender that expands and stabilizes the communication radius of compatible Ajax security systems. Designed for indoor use, ReX doubles the radio coverage and allows placing detectors and other devices at greater distances from the hub — for example, in multi-storey offices, detached garages, or large production facilities. Up to five ReX units can extend the protected area coverage to 35 km². The device supports remote configuration via the Ajax mobile app and automatic operation within the Ajax ecosystem.
Advantages
ReX increases system flexibility by acting as an additional decision-making node that relays alarms and maintains device connectivity without affecting alarm delivery speed. It is powered by OS Malevich and a powerful ARM processor, supports secure encrypted communication and Cargo protocol for reliable data synchronization with the hub, and receives over-the-air firmware updates. The extender includes a battery backup for up to 35 hours of operation during mains power loss and notifies the system about jamming or tampering attempts.
Suitable for
Large private houses and multi-storey apartments
Office buildings and multi-floor workplaces
Detached premises such as garages or workshops
Industrial and production facilities with signal obstacles

How to use
Install ReX indoors near a power outlet and within radio range of the hub and the devices you want to extend. To add the extender to your Ajax system, scan the QR code with the Ajax mobile app, give the device a name, and turn it on. In the app select which detectors or devices should operate via the range extender. Mounting is performed on the SmartBracket panel without disassembling the unit. Use the app to run signal strength tests and adjust placement if necessary.
Usage recommendations
Place ReX so that it maintains a reliable line of communication both with the hub and with the furthest devices you intend to connect. Avoid metal obstructions and sources of strong radio interference. Test signal strength from the Ajax app after installation and ensure the unit remains plugged into mains power when continuous operation is required; rely on the battery backup only for temporary outages.
