Additional Gateway/Router Installation
In some instances, it may be necessary to install an additional Gateway to support additional Routers. By
default, the Gateway and Routers are automatically assigned to channel 25. Once the first installation of
Gateway/Routers is complete and configured into the system, you must change the channel to install the
second set.
Channel selection will be site specific and dependent on the sites environmental issues. Environmental
issues include WiFi, 2.4 cordless phones, microwave ovens, and architecture (multiple Gateways). There
are 16 ZigBee channels in the 2.4 spectrums numbered 11 to 26 (1–9 are in the 900MHz spectrum).
Channel 26 is unusable as the power output is limited to half of the other channels due to its proximity to
the edge of the 2.4. spectrums, and is configured “off” in our systems.
NOTE: Channel 25 is the default for all our devices. The preferred channels are: 25, 20, 15
and 11.
