Abstract
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.
Claims19
A system for selectively controlling access to a plurality of secure areas, comprising:
- a plurality of actuators each operative to grant or deny access to a corresponding one of the plurality of secure areas;
- a plurality of access modules each assigned to at least one secure area of the plurality of secure areas;
- a driver circuit including a plurality of drivers for driving a load, wherein at least one of the plurality of drivers is operatively coupled to an actuator corresponding to an access module's secure area, and
- wherein unused drivers provided to a first access module of the plurality of access modules are output in a cascaded configuration to a second access module of the plurality of access modules.
A system for selectively controlling access to a plurality of secure areas, comprising:
- a plurality of loads each corresponding to a state of access to a corresponding one of the plurality of secure areas;
- a plurality of access modules each assigned to at least one secure area of the plurality of secure areas;
- and
- a driver circuit including a plurality of drivers, wherein at least one of the plurality of drivers is operatively coupled to an actuator corresponding to an access module's secure area, and
- wherein unused drivers provided to a first access module of the plurality of access modules are output in a cascaded configuration to a second access module of the plurality of access modules.
An access module for use in a system for selectively controlling access to a plurality of secure areas, said system including a) a plurality of loads each corresponding to a state of access to a corresponding one of the plurality of secure areas, and b) a driver circuit including a plurality of drivers, wherein the access module corresponds to at least one secure area of the plurality of secure areas, the access module comprising:
- a plurality of inputs configured to receive signals from the plurality of driver circuits;
- a first plurality of outputs operatively coupled to at least some of the plurality of inputs, wherein the first plurality of outputs are configured to communicate the signals to actuators corresponding to the access module's secure area;
- and
- a second plurality of outputs operatively coupled to others of the plurality of inputs, wherein the second plurality of outputs provide a cascaded output of the others of the plurality of inputs.
