Spec Data Sheet Button

Ajax ReX 2 Range Extender Black is a radio signal range extender with photo verification support that expands the wireless range between the Ajax Hub and connected wireless devices that gives you even more freedom to place security system devices at a considerable distance from the hub i.e detached buildings, warehouse complex or production facilities.

Please note: ReX 2 operates within the Ajax system, connected to the hub via the protected Jeweller protocol. ReX cannot pair to/extend from another ReX, it can only be paired to an Ajax Hub.

Compatible with Hub 2, Hub 2 Plus and Hub Hybrid. ReX 2 connection to other hubs, range extenders, as well as to uartBridge and ocBridge Plus, is not provided.
