Toshiba Sirens

[AllSafe]

Speaking of Toshiba motors, I used to have a Toshiba gearmotor which came out of a late-70s Canon photocopier. The thing was seriously overbuilt for its purpose; the thing was rated at 240 oz-in. torque at 120rpm.

Most of the sirens in the SONGS system were powered by a diesel generator that would send power to a controller and the blower and chopper motor. When the tone would be played over the emrgency radios. The sirens would activate. So baisically it's a omni-derictonial 8 horned system 7000 thunderbolt. I wish I got a picture of the generator/blower box before the system was taken down in '05.

I had a dream about an 8 headed thunderbolt once and i saw that picture and i though OMG how could this be true? but in my dream it rotated?? weird! Now that would be a sight a rotating 8 headed thunderbolt!

That would be 100% pointless, and fun to watch LOL.

I have still yet to see anything positively showing that these sirens ran using a blower/compressor of any type.

A Thunderbolt blower fed air to the chopper at 250 cfm at 6.5 psi, IIRC. The stator has only one port open. The Toshiba has all eight ports open. To feed air to each port at the same rate, you need 2,000 cfm, which is a honking big compressor, but not impossible. The size of the compressor would be very noticeable. How big is this "compressor unit," if that's what it is? And why all that folderol for to achieve a somewhat louder siren?[/list]

Yeah, that is a ton of CFM. I would love to see a blower to one of these if they exsist.

I believe that this siren was designed so that only four ports were open at any time.

[pyramid head]

so it has a four port chopper? (if the information is correct)
