Ajax ReX Jeweller – Wireless Radio Signal Range Extender (White, 9NA)

Product Overview

The Ajax ReX Jeweller  is an intelligent wireless radio signal range extender engineered to expand the coverage boundaries of the Ajax security system. Ideal for large multi-story residences, expansive office complexes, commercial warehouses, agricultural estates, and detached perimeter structures, ReX doubles the operating radius of connected Ajax wireless devices by establishing a secure two-way relay link with the central Hub.

Operating over the proprietary Jeweller encrypted radio protocol, ReX autonomously manages connected sub-devices, evaluating signal conditions and transmitting alarm signals in just 0.3 seconds. Even if communication with the main Hub is temporarily interrupted, ReX takes full local autonomous control over its connected devices, sounding sirens when an alarm is triggered. Powered by a built-in 110-240 VAC mains power supply with an integrated lithium-ion backup battery providing up to 38 hours of autonomous operation, it features Grade 2 anti-tamper security in a clean white casing.

Key System Features & Functionality
