A device for selectively controlling access to a plurality of secure areas includes a driver circuit including a plurality of drivers, and a plurality of access modules each assigned to a corresponding secure area of the plurality of secure areas. Each access module is operatively coupled to at least one actuator operative to grant or deny access to the corresponding secure area. Unused drivers provided to a first access module of the plurality of access modules are cascaded to a second access module of the plurality of access modules.
