Checks are always executed from an endpoint in the respective zone the host and service objects are defined in.
Therefore you would have to create additional host objects for your clients in your *master* zone. (This also applies to checks via ping, since you need to execute the checks from your master, and not from the client!)
These additional hosts in your master zone could then use "cluster-zone" as their check-command.

The cluster-zone check defined on your endpoints in the satellite zones are still useful, since you also might want to check the connectivity from the satellites, in case your master goes down.
