The NXG-433 wireless receiver adds wireless capabilities to the Aritech Reliance XR Series of panels. The receiver acts as a zone expander and supports most of the legacy 433 MHz 63-bit transmitters and functions as well as the new generation of 433 MHz transmitters and 2-way devices. The number of wireless sensors and keyfobs that can be added depends on the Aritech Reliance XR panel model. The NXG-433 wireless receiver also provides two wired zone inputs and one programmable relay output.
