The Zones tab identifies the current Zones as well as the devices in those zones. Clicking Add will open the New Zone Name window.
Devices and db Bus Devices can be placed into Zones for easier management and reporting. Zones have no effect on User Groups (other than how the Devices are displayed in the User Group). They are simply a way to programmatically break up into sections the physical layout of devices and a tool to make system management and reporting easier.
Complete the Zone Name and Zone Description (optional) and click Save. The new zone will appear in the Zones list.
