Closed wireless network (group)
With a closed wireless network a main device monitors the
radio connections with all the group devices and all the group
devices monitor the radio connections with the main device.
When a device fails, e. g. as a result of a flat battery or removal
of a device, an alarm is triggered in the main device. If the main
device fails, an alarm is triggered in all the group devices.
