Question on Factory Alarm

[SVX92-97]

I have a question on the factory alarm on my 96 Brilliant Red Lsi. I've had the car for 2 1/2 years, and the alarm has never gone off, then suddenly out of nowhere last night at 1:45AM Im waken out of deep sleep to a horn beeping sound right outside my bedroom window. Woke my wife up to, and she ran in the other room to retrieve the remote to shut it off. Then just five minutes before writing this thread, were watching TV at 11:45PM and there goes the horn beeping again. What can suddenly be triggering the alarm. No wind, nobody outside, quiet street with low traffic. Could there be a current draw from somewhere thats triggering it. Im dreading falling asleep now, as Im afraid its going to go off again. What gives?
