RARE Darien IL ACA Hurricane siren test, ORIGINAL video

This is the extremely rare black ACA Hurricane siren on top of a fire station in Darien IL. This siren was so loud it shook the parking lot! Date video taken: 8/2/2011. The end is 3:10. The video goes on after this because I thought it was going to do attack signal. Siren starts at 0:33.
