Simplex is a proprietary product. You may or may not find someone who can get you the modules. As long as the notification appliances are not addressable, you could pick up some NAC power boosters from Silent Knight, FireLite, or Altronix and move the NAC's to the boosters. The boosters usually have the sync protocols in them already. The only problem might be if there are different brands installed in the facility, or if the NAC outputs are currently mapped for other than "everything rings on any alarm".
