Why?
The first question that would come to mind when seeing this document is to ask why it is
necessary to change the frequency of devices in the system manually. Certain devices in the
RadioRA2 product family are one way transmitters (OWT). In other words, they do not
receive wireless commands from other devices in the system and can only transmit or send
commands to system devices.
In a two Main Repeater system, the two Main Repeaters will not communicate wirelessly
together. Instead they communicate back and forth over IP, connected to the same network
via a router or switch. The two Main Repeaters essentially choose different RF channels to
operate at, creating a system that is comprised of two different subnets.
To communicate the new RF channel to the devices within its subnet, each Main Repeater
will send this information to the system devices activated to it. Devices that can hear the
command will automatically change their channels from the default 434.7MHz. Devices that
do not receive and can only transmit need to be manually configured to the necessary RF
channel in order to operate within the subnet.
These procedures will need to be followed when placing OWTs on both Main Repeaters or
having sensors designed to the second subnet (the second Main Repeater to go through
activation) of the system. The first Repeater through activation will retain the default
frequency and thus not require these procedures.
All of the following procedures must always be
completed with the system in device Activation mode.
