Oh, it definitely had an alarm. I have it all bagged up. There's a hole in the tail section on the right side that goes into the glove box tail section (I've plugged it) and he gave me the original handlebar cover that has the hole for the LED indicator when the alarm is activated. If I knew it was still working when pulled (and why it was pulled), I'd consider reinstalling it. But, it's sitting in a zippie bag along with some other extra parts he had.
