AJAX ReX 2 User Manual page 24

Check the Jeweller and Wings signal strength at the installation site. If the signal
strength is low (a single bar), we cannot guarantee the stable operation of the security
system. At the very least, relocate the device as repositioning even by 20 cm can
signi cantly improve the signal reception.
If the place of installation has no stable signal level (2-3 bars) via Jeweller and
Wings between a range extender and a hub, use Ethernet as an additional or
main communication channel. This function allows you to install range
extenders in basements, metal hangars, and other places where there is no
radio signal.
Ethernet can also be used as an additional communication channel with the
hub. Connecting via wire and radio will increase the reliability and fault tolerance
of the system.
ReX 2 should be hidden from direct view. This will help reduce the likelihood of
sabotage or jamming. Also, keep in mind that the device is intended for indoor
installation only.
Do not place ReX 2:
Outdoors. Doing so may cause the device to malfunction or not work
properly.
Near metal objects or mirrors (for example, in a metal cabinet). They can
shield and attenuate the radio signal.
