A F-Series HandKey II can be operated as a stand-alone access control station, as a network master enrollment station, or as a networked access control station which receives and processes commands from a network host or a master unit.  The network master HandKey functions as the central enrollment and data logging unit for a network of up to 32 HandKeys.

The reader address for a master F-Series HandKey II is 255.  You can check it by going into the password menu, selecting the menu item number 2, and choosing "Set Address" to view the reader address.

Alternatively, you can view the reader address by pressing the "NO" button 15 times.  The reader address of the HandKey will be the third number in the string of numbers displayed: "xxxx xxxx 255"
