As Tim Castelijns points out in the comments on the question, AlarmManager has nothing to do with the device shutting down.

You are certainly welcome to have a BroadcastRecevier registered for ACTION_SHUTDOWN. Since the device is shutting down, you may or may not be able to actually play a sound or otherwise notify the user at this point in time, but you are welcome to try.
