This was so amazing!! Alton fire department set the thunderbolt off for me for my birthday!! Check them out and show them love for sure!! enjoy this behind the scenes!!
The test button activates the hi-lo signal...my brain just fried. Nice video! I remember when I first recorded the Melrose Thunderbolt, I could feel it in my chest too!
Now that I listen to the 1003 more and more it seems like a replacement electronic flasher because of how fast it alternates and no slow startup like a Signatrol Model 30 A2 would have.
@@SirensandThunderbolts1003 oh yeah it was the best siren I have heard for a fire department! I was actually mad when I first got thier. One of them was not happy about me being there and told me it already went off at noon. Then the chief came and said to her they are doing a siren test. I wanted to say the the lady CHECKMATE Lol!😁📢
