Schlage Zwave error trouble shooting

I need some help troubleshooting some strange behavior today with a Schlage Zwave lock controlled by my system. A worker who’s code has been working normally attempted to enter through the door using their code and failed, eventually generating a “lock tampered error.” A few minutes later, after calling us, they returned and were able to gain access, but the entry event does not appear in the system log. A few minutes later, the worker exited and attempted to enter again, but again their code failed and the lock generated a tamper error.

I have confirmed that other codes are functioning normally, but I am having a hard time figuring out what is going on with this particular user’s code.

Can you please provide me with the model number, manufacture date, and the firmware version of the lock please? It should be on a sticker somewhere on the device.
