Secret Entry Unit

The BR5020 Secret Electronic Keypad has been designed for high security applications that require extra precautions to safe guard the security of the lock combinations. To achieve this only two digits are displayed at one time. In normal operation mode the lock combination is entered in digital pairs. Initially the digital pair is displayed as two randomly generated numbers that are edited by the left and right hand arrow keys and then sent to the lock. To maintain reliable communication with the lock the left and right hand digits are sent separately as the user alternatively edits the left and right digits. Program Mode offers the choice of dual or single digit entry to allow for the convenient entry of single digits that may be needed during lock programming.
