Squad 51 Siren?

Skip, the sirens I was thinking of are a cross between a model 66 and 66H or 28 and 28H. The number of ports for the higher tone are different than a standard double tone. That particular version of the double tone is rare.
Well, you've mis-stated it again. None of the 60-series are doubletones. The high pitched models: 66GH and 28H have 16 ports, compared to 8 ports for the standard tone. The old Federal catalogs even describe the cycles-per-second differences between the H models and standard sirens. Federal did make a non-coasting doubletone siren for a few years in the late 50s and early 60s. There were two models available: one for Chevies and one for Fords. They were special-built to fit behind the grilles of those two cars; and because of size limitations, the doubletones were non-coasters because there wasn't room to add the coaster clutch. They also offered a special-built 28 for grille-mount applications. Sorry to say, I've never seen one of them; but a friend who used to deal in Federal products said they had a strange look to them.


As to the "H"model high-pitched sirens, Federal offered them in the 60 series and the EW series, all at extra cost. I know how you dislike the high pitches, but Midland PD had a 28H on one of its patrol cars in the '60s which was ear-shattering. I don't know if it came with a specail motor, or if it might've been a 6-volt siren running on 12-volts (as Midland was bad about that), but that one particular siren had a very quick rise to it; and it would hurt your ears. I always wanted one of them ever since and finally got one from the late John Dorgan several years ago, and I latched onto a 66GH a few years ago as well. My only other H model is an EGH.


One last word about the doubletones. It's not widely known, and I've only seen two of them, but Sireno also built a doubletone siren which they called a "dualtone". These were available by special-order only. Now those are sirens that are extremely rare. The two I've seen were both underhood models: the J8A which had no brake, and the J8B which had the brake. Both were painted in a black finish, unlike the gray hammertone color of Federal's underhood sirens (although some of Federal's underhood sirens in the '30s and '40s were black). I had a J8A that I got new back in 1964. A friend of mine in Florida dealt in a lot of used sirens back then, when prices were reasonable. You could get a used 28 from him for less than $50. I had been wanting a doubletone siren for some time. Midland had switched to the 76B underhood doubletones in 1956 and I loved that sound! I had two old sirens that I had acquired: a 6-volt S8 B&M and an old 66 (before they became 66Gs) that Federal called a "junior longroll siren". I traded both of those sirens to my friend in Florida for a brand new J8A. Not long before I made the move from here to Lubbock I loaned that siren to the Sheriff's Posse Jeep Patrol in Odessa. Big mistake! Haven't seen that siren since. If I had known that they would be so rare, that wouldn't have happened. And the sole J8B I saw was on Ebay. A friend of mine in Ohio won it and now it belong's to B&M Siren's owner, Kevin O'Connell. To conclude, Sireno sought to duplicate all of Federal's line, siren-for-siren, but not all would be stock items. The one siren that Sireno built (and there may have been others) that was exclusive to Sireno was called the "Atomic Rocket". It was built "inbetween" their Vanguard series at 8" that competed with the C-series and the 10" ED10 which competed with the Q. The Atomic Rockets were 9". I've only seen pictures of them, so I would assume that tney are quite rare.

I'm not 'mis-stating', and the sirens I'm describing are not 60 series models.


The sirens I'm thinking of have a dual tone rotor/stator assembly with 8 and 16 ports.

Well, that would be a standard doubletone, but you said they were a cross between a 66/28 and 28H. All of Federal and Sireno's doubletone sirens had 8 ports for the low pitch and 16 for the high pitch. The old Federal Catalog 300 describes the doubletones as follows: they have a high pitch (16 ports) for contrast and a low pitch (8 ports) for carrying power and range. If what you saw was a non-coasting model, then it may well have been one of those special grille-mount models that I described in my previous post.


Either way the sound of a doubletone is unmistakeable.

Model 70 series double tone sirens had a row of 8 ports and a row of 10 ports. Never seen what Wailer is describing but anything is possible.

You know, Tim, I've never counted the high pitch ports. I always assumed 16 like on all of the "H" models. Like I said, my only idea is the old special doubletones for the Chevy and Ford police cars "way back when" could've been what he saw, and they were non-coasters.

I have a picture of the interior of the Squad 51 at the Los Angeles Country museum and it is equipped with a Motorola radio and a Federal PA20A series 2E. I have a siren exactly like it, and it does not sound anything like the siren that was used in the TV show.
