A security panel with a keypad

W.W. Banks, F. Uhlig

Abstract

Several control panels presently use keypads to enter data. Sometimes panels require secure keypads in that they must prevent others nearby from seeing the information inputted by the keypad. The invention provides a secure keypad, which is easy to use by the user, yet is difficult for a nonuser to see. The invention places the keypad in a cavity, and provides an opening to allow access to the keypad and a window for viewing the keypad.
