If the connection between the hub and ReX 2 is lost, all devices connected to the range extender also lose their connection with the hub.
Devices that have lost connection with the hub cannot transmit events, alarms, or photos to users and the security company monitoring station until connection is restored.
Thanks to OS Malevich, the range extender combines detectors into an autonomous group. If ReX 2 receives an alarm signal from the detector after the loss of communication, the range extender will activate the siren connected to it.
