Ajax ReX | Signal Extender | Jeweller
Summary
The ReX Jeweller is a professional wireless radio signal range extender designed to expand the coverage of Ajax security systems. Using the proprietary Jeweller wireless protocol, it extends communication range up to 2 times the standard distance, enabling installation of Ajax devices in larger facilities or areas with challenging layouts.
Designed exclusively for indoor use, the ReX Jeweller features dual power supply with mains power (110-240V) and a built-in rechargeable Li-ion battery providing up to 35 hours of backup operation. The device communicates with the hub via encrypted radio signals with frequency hopping to prevent interference and jamming, delivering alarm notifications in just 0.3 seconds.
Compatible with all Ajax hubs (except uartBridge and ocBridge Plus), the ReX Jeweller can be configured and monitored remotely through the Ajax mobile apps for iOS and Android. The system supports up to 5 range extenders per hub (depending on hub model), with each extender capable of connecting up to 199 devices, making it ideal for protecting expansive residential and commercial properties.

FAQs
What is the ReX Jeweller and what does it do?
The ReX Jeweller is a wireless radio signal range extender that expands the communication range of Ajax security systems. It allows you to install Ajax devices at greater distances from the hub by acting as a signal repeater, effectively doubling the coverage area of your security system.
How many ReX Jeweller units can I connect to my Ajax hub?
The number of ReX Jeweller units you can connect depends on your hub model. The standard Hub supports 1 ReX Jeweller, while Hub Plus, Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, and Superior Hub Hybrid all support up to 5 ReX Jeweller units per hub.
How many devices can be connected to a single ReX Jeweller?
Each ReX Jeweller can support up to 199 devices, though the actual number depends on your hub model and its total device capacity. It’s important to note that ReX Jeweller does not increase the total number of devices your hub can support—it only extends the wireless range.
What is the wireless range of the ReX Jeweller?
The ReX Jeweller provides radio communication range up to 1,800 meters between the extender and the hub in open space. The actual range between the ReX Jeweller and connected devices is limited by each device’s individual radio signal range, as specified in that device’s technical documentation.
Does ReX Jeweller work on battery power?
Yes, the ReX Jeweller has a built-in rechargeable Li-ion 2Ah battery that provides up to 35 hours of backup operation when external power is lost. The device is primarily powered by mains electricity (110-240V) and the battery charges automatically while connected to external power.
Is ReX Jeweller compatible with all Ajax devices?
ReX Jeweller is compatible with most Ajax devices that use the Jeweller wireless protocol. However, it does not support pairing with MotionCam motion detectors with visual alarm verification, as these devices use the additional Wings radio protocol. The extender only works with Ajax hubs and is not compatible with uartBridge and ocBridge Plus.
Can I use ReX Jeweller outdoors?
No, the ReX Jeweller is designed for indoor use only. It has an IP20 protection class and operates within a temperature range of -10°C to +40°C and humidity up to 75%. Installing it outdoors may damage the device and void the warranty.
How do I know if my devices are connected through ReX Jeweller?
Devices that are paired with and operating via ReX Jeweller will be marked with a special icon in the Ajax mobile application. You can assign devices to the extender through the ReX Jeweller settings menu using the “Pair with device” option.
How fast does ReX Jeweller communicate alarms?
The ReX Jeweller delivers alarms to the hub in just 0.3 seconds, ensuring rapid response to security events. The hub polls the extender every 12-300 seconds by default (36 seconds standard), but alarm communications are prioritized for immediate transmission.
Can I connect one ReX Jeweller to another to extend range further?
No, daisy-chaining ReX Jeweller units is not supported. Each ReX Jeweller must connect directly to the hub. You cannot connect one range extender to another range extender. However, you can install multiple ReX Jewellers (up to 5 on compatible hubs) that all connect directly to the hub to cover different areas of your property.
What happens if ReX Jeweller loses connection with the hub?
If the ReX Jeweller loses connection with the hub, the LED indicator will light red continuously, and you’ll receive a notification in the Ajax app. The system detects communication loss after 36 seconds (depending on your Jeweller settings). Devices connected through the ReX Jeweller will not be able to communicate with the hub until connection is restored.
How do I test if ReX Jeweller is installed in the right location?
You can use the built-in Jeweller Signal Strength Test to check the signal quality between the ReX Jeweller and the hub, as well as between the extender and connected devices. Access this test through the device settings in the Ajax app. For optimal performance, ensure the signal strength shows at least two bars.
