What would cause Tamper Alert on the NDE lock?

Tamper Alert is typically caused by a missing or misaligned magnet behind the Strike Plate on the door frame on the original NDE locks.

There should be two magnets on a plastic strip that gets installed behind the Strike plate.

If these are newer NDEB locks, that magnet has been replaced with a door position switch.
