Back in '83 I had a Cadillac El Dorado Touring Coupe (I miss that car) with a Black Bart Alarm system installed. It had a sensor inside to detect window breakage and even a slim jim being used based on sound. One weekend right after I got it I went out of town for 3 days leaving it home. I got home to a note on my windshield saying the alarm kept going off all weekend. Long story short, I left my watch in the car and
every hour on the hour it would "beep" setting off the alarm. My nieghbors were pissed.
