Hmm, I am not seeing any active trouble conditions on the account, or any within the last couple weeks. The last trouble was a door sensor tamper on 3/22 based on reports from the system to Alarm.com.
What do you see in Settings > Status > History? Are there any indications of the trouble event?
Are all touchscreens beeping or is it just one remote? Both remotes?
It would be good to make sure the panel is updated to the latest firmware:
