Radio Channels - EMS FIRECELL Programming Manual

5.6 Radio Channels

This menu allows the frequency channels currently used by the system to be viewed or altered.
NOTE: Alterations to the Radio Hub and RCC communication channels can only be undertaken
when no RCC's are allocated to the system. Alterations to the RCC and Device communication
channels can only be undertaken when no devices are allocated to that particular RCC.
This can be achieved either manually or automatically. Two channels are required to be selected
for the Radio Hub to RCC communication path and two separate channels for the Device to each
RCC communication path. It is not possible to select the same channels for these communication
paths. When selecting the radio channels, one channel must be from the Low Band range and the
other must be from the High Band range. This will ensure a minimum of 100 KHz spacing
between channels. The Radio Channels used to communicate between the Radio Hub and the
RCC's are factory set. It is however recommended that it is re-configured to suit the sites
environment. This must be performed before any RCC'S are added to the system. The Radio
Channels used to communicate between the Devices and the RCC's are also factory set. It is
however recommended that it is re-configured to suit the sites environment.
