This is a video of my 3 sirens (Model 2T, Model A, and Thunderbolt 1000B) running alert for the ringing the New Year 2018. I was originally going to re-record the Federal Model B in Greer, SC but the fire department told me "the siren doesn't work". So I decided to stay home and do the sirens blast. Yes, the Model A is high pitched. I'm working on using a "new gadget" for future siren videos.
