Very good quality videos, Derek! Why did that 1000T's blower malfunction exactly?
On a side note, was that Thunderbolt set at factory chopper settings? What level is considered "factory settings"?

5 is the common setting

Are you sure that 2001 is the 130? It does not look or sound like the 130 model.

It's definitely a 2001-130.

This Thunderbolts TB105 is set to Terminal 4. I am not sure on the factory setting, may be 4 since it's the middle terminal.
Ah ok, I've seen that happen once before when someone was standing too close to an intake pipe on one like that. I really underestimated the suction power of that blower before I saw that!

Thanks Archon! I've been wondering what it was for a while now, and now I know!

Nice SD-10 video. I love how the snow goes flying out of the siren.

Does anyone have any recordings of a Thunderbolt 1000T that they're sure is set to a level 5? I'd like to hear what that sounds like. I've been trying to figure out what these chopper levels sound like for a while now.

You can be sure what level any Thunderbolt is set to by listening to it. Bad brushes and worn motors and bearings can lower a pitch. Also, it depends on if the siren is hooked up to a 208v 3-phase or 240v 3-phase power source. Even some utilities (especially on older single phase transformers) may have their single phase service set to 220v. These are unique sirens that you never know what you'll hear when you see them go off for the first time.

Why does this Model 2 have an extra set of numbers? Is it additional detail into the horsepower it runs at?
My reasoning for the question is that I've heard various Fed 2's at different pitches: One near my home does an almost perfect C major, most others run at more-or-less C-sharp (like this one) and still others at a D-major or even slightly higher.
My apologies for the note-based references. The tattered thread's worth of of musical talent on my part demonstrated above makes any extrapolation I could make to Hz level a chore.

The extra set of numbers is the voltage.
