Hello I got a YouTube video I recorded of Fennimore Wisconsin new 508s they were installed in September 2017. These have been amazing sirens I'm only 4 blocks away from the one I recorded the other is by the rail road museum there are only 2 sirens sadly there were originally 7 sirens. The sth 10s and model 2 and model 5 are gone to other surrounding communities in my area here's my link for the 508 close up
