Frequently asked questions
What does ReX do?
It roughly doubles the Ajax system's radio coverage, linking distant devices to the hub in large houses, across floors or in spaces with thick walls.Does it need an Ajax hub?
Yes. ReX runs on Jeweller and connects directly to an Ajax hub (not to another extender). It is compatible with Ajax hubs.How many devices and how many ReX?
Per ReX: up to 99 (Hub/Hub 2), 149 (Hub Plus) or 199 (Hub 2 Plus) devices. Per system — up to 5 ReX.Does it work during a blackout?
Yes. The built-in backup battery provides up to 35 hours of operation without mains — useful during power outages.Does it support MotionCam?
No. ReX does not support MotionCam detectors (with photo verification). For those, ReX 2 is used.What warranty and delivery do you offer?
24-month official warranty from Evrinet SRL (official Ajax importer). Delivery across Moldova, showroom in Chișinău at str. Columna 153.
