Oh trust me though they were. If I remember it right lincoln NE had more 1000s than 1000Ts (in fact I think they still do...) But these days I agree that the 1000Ts have caught up and gone over the 1000 number for sure.

Someone may be able to chime in on this but I heard someone say that Civil Defense made a law that dual tone sirens were required back in the day but it's all a blur to me.

"Civil Defense" was not a lawmaking body.

That said, congress did allow communities to apply for matching government funds for some civil defense purposes, civil defense sirens included. By no later than 1954, if you were to receive matching funds, the siren had to be dual tone. But that's only if you were purchasing a siren for civil defense with the appropriated money (and were granted the funds). Single tone sirens were sold and marketed as general alarm sirens (ex. fire sirens). Doesn't mean communities couldn't buy them and install them, they just wouldn't be eligible for the government funds.

Here's an SD-10 ad that directly references this (take it for what it is as a marketing tool)
To the OP: sorry for adding to the derailment of your thread.

Cool thanks.

As Mr. Spock would say: "Fascinating"

Maybe you heard from a Canadian thread. In Canada every siren had to be dual toned, not a law because every siren was installed by the Federal Government but was just mandatory (commonwealth).

I don't believe that is correct.

In 1959 when Dallas put in their first thunderbolts at fire stations (all 1000s) they received matching funds for the sirens.

And yes, matching funds were available for all kinds of CD purchases; boats, trailers, trucks, sirens, municipal shelters etc. etc.
