More Info on the anti theft alarm system

The Lexus RX350 has a remote anti theft alarm system,  Does it work similar to a regular alarm system that can be installed in a vehicle?  What would trigger such an alarm and how loud is it?

I believe the alarm will sound if someone successfully opens a door without unlocking the door using the fob.  Like breaking a window or using a jimmy tool.  I think you can verify by rolling down a window, then put your fob away, but nearby.  Then open the door by reaching through the open window and using the interior latch.  I don't think there's any type of motion detection.  Push the "Panic" button on your fob to see how it sounds.  I believe it just honks the horn, but may keep honking until you shut it off.  Again, check your Owner's Manual to verify alarm operation.
