Yes it's a single phase P-15. The single phase Doerr motors on these sirens spun a little slower than the three phase models. You can also hear the start windings drop out right before it hits top pitch on the windup, which is a dead giveaway it's a single phase model.
Yeah, it has three phase service, since it's next to the water tower, but that thing either has a 10hp 3ph Doerr in it that's trying to go out, or a 15hp 1ph Doerr with the three phase service being tapped down to single phase in the box. Either way, it's got a "single phase" hiccup.
I'll call tomorrow and ask to see the wiring diagram, it comes in handy to have friends at dpw, but my contact told me that the 3 phase runs all the way to the siren head.
These sound ALOT better than the T-128 and T-135's.

Awesome video! You seem to rarely see a gray dual-toned P-15. Really cool. i love the wind down.

Is it a P-15? The pitch sounds very close to the P-10 blackmaxima filmed.
