I think the most common reason for a tamper alarm going off repeatedly is architectural: too much vibration on the door. I knew one situation where an apartment’s door lock vibration alarm went off every time the door to the apartment one floor below it was slammed. Another where closing the garage door would set off the interior door tamper alarm. Still another on a house where a heavy truck driving by could set it off.
The first thing to check is whether the tamper alert has a configurable sensitivity.
Second, look at the door itself. Is it seated well? Slightly warped? Try knocking on the door and see if that sets off the alert.
Sometimes the easiest fix is new weatherstripping on the door, which will usually reduce the vibration.
You can also temporarily put a vibration sensor on the door for more diagnostics.
In a few cases it’s the fit of the lock against the door that’s the issue, particularly on a warped door. If there are any gaps, that can cause vibration in the lock itself. Sometimes this can be fixed with caulking to seat the lock more firmly.
It usually just takes detective work to find the source of the vibration.
