ReX 2 expands the radio communication range of the security system, allowing the
installation of Ajax devices at a greater distance away from the hub.
ReX 2 receives hub signals, transmits them to the connected devices, and sends
signals from devices to the hub. The hub polls range extender with the frequency of
12 to 300 seconds (depending on the settings, the default value is 36 seconds).
ReX 2 range extender polls all connected devices with the same frequency.
Regardless of the settings, all alarms are delivered in no more than 0.3 seconds.
The communication range between ReX 2 and the device is limited by the radio
signal range of the device. Radio signal range is indicated on the device page
and in the User Manual.
If the device loses communication with a range extender for some reason, it does
not automatically connect to another range extender or hub.
