The Siren Board

I'm not sure if the stator is iron or steel, but I am quite sure it is not aluminum. If it is, that is the thickest and heaviest piece of aluminum I've ever dealt with.

Well, the area of the stator between the horns seems rather unaffected, so the inside must be protected from the elements even better.

Shoot, that thing is 99.9% guaranteed to be frozen up form both rust and surface aluminum oxide form the rotor. If you flipped this thing on, the motor would hum until it burned up.

Aluminum oxide is a very thin layer of oxidation, at least much thinner and smoother than rust. I think that the rust would be responsible for more than the aluminum would be. Since sirens require very close tolerances, though, maybe the thing would be locked up.

Yea, your right about the aluminum oxide actually. Not all rotors are made of aluminum then, because some do flake quite a bit. I've seen a model 5 with this problem before, and I have two single tone model 2 rotors from the same time period and only one has that flaking (it's not really it flaking but I'm not sure how else to describe it).

I guess I need to take some pics.

As much as the salt air may have affected this, looking at the fact the bells are rotted out _on_the_top_, I'd say there's been some influence of some seagull effluent, too.

Bird poop is a nasty, nasty thing for metals!!


Bleehhhh!!

If that works, it probably would send pieces of the horns everywhere.

This STH-10 is in the worst condition of any that I have ever seen. It goes along the lines of several Florida Model 2s where the housing has turned into a few strips of rusted metal. This siren is located south of Leeville, LA...better known as the Gulf of Mexico.

Ugh, that's just awful. Are they really that lazy to repair it or replace it with another Omni-Directional Siren like a FS Eclipse 8/Sentry 7V8-B/ASC-T-12/FS Model 2?

Probably doesn't matter now. The siren has been removed since the post from what I could tell on google earth

Just needs a little Bondo and duct tape.
