Our old 2T22s messed up when a car crashed into a certain power control box and knocked down some wiring and the sirens wound up and went on and off for about 15 minutes.
About 5 minutes ago on the news I saw a car that ran into a road sign and then into a pole with a Whelen WS-3016. The siren is damaged, and I don't think it can be repaired.
See if you might be able to find a video clip of it. www.kotv.com
