How to use the beeper in a card reader to beep a different pattern for valid access and invalid attempt.

Issue

Continuum access controllers such as the AC1Plus or the ACX5740 do not have a way to drive the beeper of a card reader directly, however the beeper can be driven using the same lines that drive the LED on the card readers, using this method different beep patterns can be accomplished to audibly differentiate between valid access and invalid attempt for example.

Environment

AC1Plus

ACX5720

ACX5740

CX9702

Cause

Design

Resolution

Typically the reader will have a wire labeled as beeper.

  1. Connect the beeper wire to the reader LED termination on the card reader connector at the controller.
  2. Select the reader led pattern that gives the best results for your application, see Lessons Learned Article #2860 for steps on selecting a reader LED pattern.
