How-to: Door Contacts and Request to Exits are not Responding on Correct AEC 1.0 Address

Issue

When the Request to Exit input is shorted on a board, the correct strike relay fires, but the AEC Activity Screen shows that a different door was opened.

Solution

Verify that you have configured jumper JP1 on your reader board correctly.  JP1 is the jumper responsible for addressing the Request to Exit and Door Contact inputs on the board.  If you addressed JP1 incorrectly, the strike relay will respond on the reader board, but the AEC messages and programming will react to the address you configured with JP1.
