Model A siren

[bwf76]

I just purchased a Model A type siren from ebay (brand new). Does anyone know where or who could make this into a two tone type siren (like a model 2t, thunderbolt 1000t, etc..) The siren is 110 volt siren. I know on past discussions, Federal Signal no longer will make their outside sirens (Model 2) a dual sounding siren. If anyone has any suggestions, please let me know. Thanks.

Unless you are a gifted machinist, I doubt it could be done. The Australian "Wailing Joe" siren that Justin once overhauled was a dual tone siren that looked like a Model A, so perhaps the rotors are similar. Now you just need to find one of those, which could involve traveling to Oz.

Umm... It might have been. Someone said that the "bars" over the stator ports might have been guards to stop things from getting amputated. Footy season's over so I won't be able to get a recording of it, but my guess would be that it would be most likely single tone.

Sorry for the confusion there. I wish I still had those pictures.

Wailing Joe is the only one I know of around these parts and I haven't seen any others. I'll keep my eyes peeled for another.

Did the rotor and stator have two sets of ports with different numbers?

Unfortunately because of the angle of the outside horn I couldn't really see that far into the rotor and stator assembly.

I have a gut feeling that those images are on one of my many backups somewhere along the line (and hopefully on my main hard disk), so I'll have a look for them.

No, the Model A was single toned, and had 6 ports, whereas the Model L had 8 ports.

No luck. They're long gone.

If I find another, I'll be sure to snap it up.

Thanks to all for checking reference my siren question. If anyone knows anyone that might be able to turn this into a two tone, contact me!!

Thanks again,

The only thing I can think of would be to get another similarly-sized siren stator and rotor with a different port count and using a twin-shafted motor to mate it to the Model A, but this would be creating an entirely different siren than a Model A.
