Random Bell Tamper

So after having a system for a couple years, this past month I started to get a completely random Bell Tamper. I checked the wire from the bell tamper to the Hardwire 16 to be secure.
I also checked that the screws on the Bell box outside were secure as well. I’m on IQ2 with the latest firmware.

Any other things I should check? Kind of at a loss of why this would start just randomly show a tamper all of a sudden. Thanks.

Is the tamper persistent or intermittent?

If they are connected to the HW16 to trigger the relay for a wired siren, can you try fully power cycling the HW16? Leave it powered off for a minute before powering back up. Then reboot the panel.

Does the alert come back?
