Use this dialog to specify the devices or device groups to which an Alert Center threshold does or does not apply.
Note: When you add a device group to the list of exceptions, all devices within this device group, as well as any sub-groups contained within the group (and devices in those sub-groups), are excluded from, or include in the threshold. Additionally, if you add a device group to the list of exceptions that contains a device shortcut, then that device is excluded from the threshold—even if that device is also a member of another group which is not part of the list of excluded groups.
Tip: To delete a device or device group from the list, select it, then click Remove.
