Tamper board is a single board with a tamper button. The button contacts change a state when you try to open the casing lid or detach it from the surface. An Ajax hub receives a notification about the tamper triggering of the device. The hub activates the sirens added to the system, triggers scenarios, and notifies users and the security company.
Case has the tamper board. It’s connected to the Ajax device with a loop in the complete set.
