AJAX REX Range Extender (Hub Support), Black and White
The AJAX REX Range Extender (Hub Support) is a wireless accessory for the AJAX alarm system. Its purpose is to support the AJAX hub by extending the range of the system’s wireless network. Where a device is too far from the hub, or where building materials block the radio signal, the REX can help connect it to the system.
Wireless alarm systems rely on a stable connection between the hub and each device, such as motion detectors, door and window contacts, keypads and panic buttons. Distance, thick walls, metal structures and multiple floors can all reduce that connection. A range extender placed between the hub and a distant device helps maintain communication without running cables through the building.
Key features
- Designed to extend the wireless range of the AJAX hub

Specifications
The supplier description does not list detailed technical specifications for this item. For dimensions, power requirements, radio frequency, compatible hub models, operating temperature range and warranty terms, please refer to the official AJAX documentation supplied with the product.
Typical uses
The REX suits a range of situations. In a family home it can reach a garden shed, garage or upper floor where a sensor would otherwise be out of range. In an office it can extend coverage to a storage room, server room or reception area at the far end of a building. In a shop or warehouse, it can help cover long aisles or separate units that sit beyond the hub’s direct reach.
It is also useful when a system is expanded over time. Adding new detectors or keypads to an existing installation can reveal coverage gaps, and a range extender offers a way to fill them without moving the hub or rebuilding the setup.
Choosing the right colour
The black and white version is intended for installers and customers who want the device to blend in with their interior. Because the colour is part of the product code, check that you order the variant that matches the rest of your installation.
Installation and planning
Before installing, walk the site with the AJAX app and check the signal strength at each location where devices will be placed. This helps identify where a range extender will make the most difference. Place the REX between the hub and the distant devices, away from heavy obstacles where possible, and test the connection after installation. Follow the manufacturer’s guidance on placement and mounting.
A well planned installation keeps the system reliable and easy to maintain. The REX is one tool among several for achieving that, alongside careful device placement and regular checks of the system’s status in the app.
Who should consider this product
The REX is aimed at homeowners, property managers, security installers and businesses who use the AJAX system and need coverage beyond the hub’s immediate area. It is a practical choice for anyone who wants to extend their alarm system without adding complex wiring.
