ReX receives hub signals and transmits them to the devices connected to the range extender. It also transmits signals received from the devices to the hub. Two-sided connection is provided by the Cargo protocol operating over the Jeweller radio protocol.
Unlike regular range extenders that only re-broadcast signals, ReX controls the functioning of the security system devices. By copying the system information from the hub, ReX creates an autonomous group of devices and responds to events instantaneously. If the hub disconnects from the network for whatever reason, ReX receives an alarm signal from the detector and activates the siren.
ReX does not increase the number of devices connected to the hub!
