Hey Guys,
Just went to Sandwich Illinois yesterday to record the Thunderbolt 1000T as you already know I have recorded it doing Alert signal. But never recorded it doing both Alert and Attack signals at the same time. This was the first time for me to record a Thunderbolt 1000T siren doing both Alert and Attack signals. Usually Illinois only do Alert signal. And that's it. And this time I was a lot closer to the Thunderbolt 1000T siren. Don't worry I had ear plugs in my ears on. Never realize how powerful these amazing sirens are, Both the Thunderbolt and the ACA Hurricane-130 siren. Didn't realize how much of a volume boost the blowers give to both sirens. Without the blowers they will be almost completely useless. Here's the link to the siren test video. https://youtu.be/2mYICBPVKRs
