I agree about the dual toned sirens. There are dual toned model 3's and since the 2001 appears to use a model 3 chopper it would not be much of a stretch to make it happen. I also like asc 8 port sirens. The cool thing on test day is to drive over between Coon Rapids roundback 2001 and Andover's T1...

Is the Model 20 actually 20hp? Someone told me a long time ago but i doubt it's true. I don't know if anyone has ever confirmed or denied that. I wouldn't think so, but I could be wrong I sorta believe it if its a dual rotor siren. Its just that it looks a bit too small to be 20hp too... hmm...

I'm planning on making an Ohio statewide siren map that maps only the analog Whelen sirens in the state. If i could get some help with it that would be greatly appreciated! (Your name will be added in the description if you contribute to the map!)

According to Franklin County's webpage, Franklin County has 196 total sirens that are activated in four different zones.

The Newark Thunderbolt might not even have a rotator in there. If you look at a siren map of Newark, one of their Thunderbeams is awfully close to the back side of the Thunderbolt. Probably just a bit over 3 quarters of a mile away even. That leads me to believe that when the system was installed, t...
