Ajax ReX – signal amplifier, white

Ajax ReX

Ajax ReX gives your security system the range it needs. This intelligent radio signal range extender lets you install your Ajax devices (motion, door and window detectors, sirens, etc.) further away and in sites with more complex layouts, such as multi-storey offices, detached houses, warehouses or production buildings.

Why choose ReX?

• Greater coverage: ReX can relay the signal between detectors and the hub at up to 1,800 m in open space. With one hub and up to five ReX units, system coverage can reach up to ~35 km².

• Fast, reliable alarms: alarms are delivered in just 0.3 seconds, even when ReX is relaying all device data.

• Autonomous control: ReX is compatible with all Ajax hubs and works together with them. If needed, ReX can take over system control when communication with the hub is lost, for example activating a siren when a detector is triggered.

• Backup power and tamper protection: the device runs on 110–240 V mains power, and its built-in Li-Ion battery provides up to 35 hours of operation even during a power outage. ReX also protects the system against compromise: the signal is encrypted and the device detects tampering and signal jamming.

• Easy installation and setup: connect to the hub, scan the device QR code, name the ReX and mount it on a wall or surface using the SmartBracket. No complex wiring or specialist installation required.

Who is it for?

Ajax ReX is ideal if:

• You need a security system for a large house, villa, warehouse or a property with several buildings.

• Your devices are located far from the hub or need to be spread out, for example in a garage, second house, barn, basement, etc.

• You want your security system to work reliably even during a power outage.

• You have multiple detectors and devices that you want to manage as a single system and need secure, fast signal transmission.
