When a panel tamper occurs on a Qolsys IQ Panel 2, the panel announces that there is a panel tamper and the trouble condition appears on Alarm.com. 

The tamper switch on a Qolsys IQ Panel 2 is the black button on the bottom left side on the back of the panel. 

How to resolve: 

1. Affix the backplate onto the panel and verify the black tamper button is pressed down. 
2. Once the device's tamper is restored, request an equipment list to verify that the trouble condition is resolved. For more information about updating the equipment list, see Request an updated sensor list.
