ReX Jeweller by Ajax is a wireless signal range extender designed to expand the communication distance between the Hub and system devices. It enables sensors, sirens, and control units to operate at significantly greater distances, making it ideal for large homes, multi-floor buildings, offices, and extended indoor spaces. It uses the secure Jeweller protocol with anti-jamming protection and includes a backup battery for continuous operation during power outages.
