ADT Smartthings alarm volume wont turn all the way off

My ADT Smartthings hub has 2 devices in tamper mode and is making an alert noise every minute or so. I have the 3 volume settings turned all the way down but I can still hear the alert anywhere on the first floor. I am trying to figure out how to clear the tamper mode for the device (without resorting to remove them for the nth time).

How do I totally turn off all sound from the hub?
How do I turn off the alert that the system is not ready to arm?
