Issue

How to tell if an AC-1 Plus card reader has been tampered with

Environment

AC-1 Plus card reader

Cause

Knowing whether a card reader has been tampered with is an important security measure.

Resolution

  1. Set up an InfinityNumeric. Name it anything.
  2. Set its IOU number the same as the entry IOU (or exit IOU) of the door and set the channel number to 6.
  3. Set the direction for IOInput.
  4. The value of the numeric represents the status of the reader.
    • 0 = Normal
    • 1 = No Reader Present
    • 2 = Reader Voltage problem
      NOTE: This only works on the AC1Plus access control module.
