Protege Alphanumeric
LCD Keypad


The Protege Alphanumeric LCD Keypad provides a user friendly human interface to the Protege integrated system, providing seamless and powerful integration of access control, security and building automation. In addition to sophisticated access features, the keypad incorporates system monitoring and control. Authorized users are able to perform arming and disarming, monitor inputs, control outputs and manage user access, all from the convenience of the keypad.

  • Support for two factor authentication with ID and PIN or card reader and PIN
  • Individual reportable duress code for each LCD Keypad
  • Customizable display options


The keypad allows a user to arm and disarm an area or group of areas:

  • Area progress is shown on the LCD display, which guides the user through the arming or disarming procedure with user friendly plain text messages
  • Easily view open system inputs during the pre-arming phase
  • Local display of user area for quick confirmation of arming and disarming
  • Direct input bypass option

The keypad can be programmed for a custom auto logout time specific to each station.

Monitoring of all objects within the system can be achieved from the keypad:

  • Monitor the status of any door, user (anti-passback), input, or output directly
  • Offline functions allow quick key menu functions to be performed on objects used for automation (lights, HVAC, gates, doors)
  • Single automation quick key for REX (Request to Exit) or output activation

The Time & Attendance feature enables entry, exit, and even break times to be displayed on the keypad, providing users with a clear and definitive view of their recorded start and finish times.

User management functionality provides a quick and convenient way to manage users at the keypad. Users can change their PIN code at any time, and enforced periodic expiry of PIN codes can be configured to improve system security. Authorized users are able to add new users with immediate access, modify incorrect user settings, and delete user records to immediately withdraw access.

To provide an increased level of security, a site can be configured to require dual credential authentication for user access to keypads. A reader can be added to require both card and PIN validation, or the keypad can be configured to require both user ID and PIN. The site can also specify PIN complexity rules and enforce automatic periodic PIN expiry to ensure regular changing of PIN codes.

Extending the Protege system with local inputs and outputs allows convenient and cost effective expansion with additional benefits:

  • 4 inputs which can be used to perform any system alarm and automation functions with a dedicated enclosure tamper switch
  • 1 low current output for driving any signaling device
  • Configuration and addressing of the keypad is achieved by an easy to follow configuration menu available during initialization

A single RS-485 communication interface port used for all network communication functions and interconnection to other modules.
