The Siren Board

Are Dual Toned P-10's really as rare in this country as they are on youtube? I only see one video and that is BlackMaxima's "Genuine Three Mile Island Siren". I can't find any more. I'm recording one at 12:15 and I'll put it up.

P-10s are just Allertors with a different Shroud they started making them with the new shroud in the 80's and by mid 90s stopped making them.

Here is my video of a dual toned P-10/15 from a few months ago.

The only difference between the P-10 and the P-15 is the motor. One is 10hp and one is 15hp. You can tell them apart by the speed of the wind up.

This single phase dual tone P-10 was installed and filmed by a Board member a couple of years ago. It has starter cap problems in the video, but it has since been fixed.

I believe that the single phase version of this siren is much rarer than the three phase version, because there were a lot of problems with the single phase motors.

The dual tone P-15/P-10 used the same innards as the S-10 screamer, Banshee, Howler, and Allertor. ACA just tweaked the housings and and played with the ratings.
