I'm talking about Hamilton County's sirens.

[Midwest Siren]

I saw the Hamilton County video and I don't see how putting a Model (?) on a roof or pole can be very useful for tornado warnings. People a mile away might not even hear it very well.

Are you sure there are only 3 Tbolts left? I know of atleast 14.

I know of the one by Sawmill off I-270, one in Gahanna, and 2 down by OSU campus.. so i'm sorry, I meant 4 that I have seen.. Where are the others? According to the list the rest were Whelens


And what is Midwest Siren talking about? Sirens on a pole or roof top.. As far as I know that's how you mount them.. what methods do you know of that will warn people a mile away?

Well that's kinda the reason why they install OTHER SIRENS. And Hamilton county does have a few others...more than 190 actually.

Actually 207 If I remember

Ok you didn't listen to what I said. I know that im saying the Model sirens. Model 2,3,5,7t whatever it is.

[jkvernon]

No, I knew what you meant. Those sirens were either originally there as fire station sirens then later added to the system with county controls or they were installed as a fill in siren where a larger siren like a TBolt or P-10 weren't needed.

There's nothing wrong with a model 3 5 7 SD10. I'd prefer them over any of those other sirens out there, they look and sound the best. Besides no matter what type of siren you have, you aren't going to hear it a mile away inside your home anyway unless it's at 3am and you are up getting a late night snack with all the windows open.

Just to keep in mind.. as far as I know, sirens utilized for weather have only been in use for 10 or 20 years.... From 1940 to probably the 1970's sirens were mainly used for CD air raid and fire.. The idea for bad weather sirens came about after the cold war ended.

[Midwest Siren]

Ok, but for coverage a Model 2,3,5,7,T wouldn't be the best decision compared to sirens that give greater coverage such as a rotating siren or a louder omnidirectional siren. However it would be a smarter decision to use the Model sirens for very small towns and whatnot.

First off I wanna make sure I get this across.

Okay, let me spell this out for you. I think it's obvious that a small siren is appropriate for a small town, which is what Hamilton County used to be made up of along with the city of Cincinnati which is rather large. But over time cities tend to GROW which brings the need for more sirens to cover the areas that either have grown or will grow which brings the need for large output sirens. If the city finds a small gap between sirens where a large siren wouldn't be needed they install a small siren. So there isn't anything unusual about how the Hamilton County system is laid out.
