Monitoring (armed home) false positives?

So I have been using home monitoring for a little while now and ive noticed 3 times now (last time was 5:46 am today) where the system starts beeping (as if their were a breach)
I dont know what will happen if I let it finish. Guessing it will call security for me… So I go in quick (while im sleeping) and disarm it.
Is there any way to figure out exactly why it did this?
Clearly no doors were open, etc. So I just want to try to figure out why this is happening.
If I cant trust the system, I cant use it.
Thanks
