SD-10s are 9/12 port. Federal never made any 8/10 port sirens. The closest thing they've made is the Model 2T and Thunderbolt 1000T which were made in 4/5 port at some points.Ohio_Man wrote: ↑Wed Dec 02, 2020 1:53 amYou'd need to replace the rotor and stator to make it an 8 port. Federal used off the shelf motors for their sirens so they should be the same. I'd try and trade your siren for an 8 port since it would be easier than hunting down parts. Is yours the dual tone 8/10 like an SD10 or is there a port ratio I'm forgetting?
You're right, but what are the 5 port dual tones? Do they share the same as the SD10's?Zarlog wrote: ↑Wed Dec 02, 2020 3:28 amSD-10s are 9/12 port. Federal never made any 8/10 port sirens.

The 5 port dual tones sound like this:Ohio_Man wrote: ↑Wed Dec 02, 2020 4:32 amYou're right, but what are the 5 port dual tones?

Just look up "federal signal model 5t". They're very obviously 9/12.Ohio_Man wrote: ↑Wed Dec 02, 2020 8:24 pmSorry, I meant port ratio of a dual tone model 5. Not a 5 port siren.
But yeah you can't wire a siren to have different port ratios you're gonna be looking for either an 8 port rotor and stator, and at that point you should trade your dual tone (I'm guessing 9/12) model 5 for a single tone one.
