14 9600 Series Wireless Call System (0510-1078-D) - Hardware Installation Guide
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 are complete and configured into the system, you must change the channel to install the
second set.
Channel selection will be site specific and dependant on the site’s environmental issues. Environmental
issues include WiFi, 2.4 GHz cordless phones, micowave ovens, and architecture (multiple Gateways). There
are 16 ZigBee channels in the 2.4 GHz spectrums numbered 11 to 26 (1–10 are in the 868–928 MHz
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. GHz spectrums, and is configured “off” in the 9600 Wireless Call Systems.
Channel 25 is the default for all 9600 Series devices.
