Yes that is the correct way to control a separate zone. With a pressure reducing valve. It is stated in nfpa 20

The insurance inspector wants the existing pressure reducing valve to be replaced with a pressure relief valve. The pressure reducing valve is downstream of the fire pump and limits pressure on a supply to an older part of the facility. Joe C. Powell Pruett Ford & Associates, Inc.
