As seen on American Restoration!! Except this one is
You are offerding on a complete Air Raid Siren/Tornado Siren/ Storm
Warning Siren/ Neighbor Annoyer. It's a
Thunderbolt 1000 from Federal Signal. Everything that is testable works. I
could not test the wireless receiver. I put this all together to sell a
functioning piece. You will need to supply a plug or power interface. Wiring
between the parts are only temporary but do work. If you plan on using as is, and not
restoring, you would need to bring the wiring up to code for your local authorities.
Currently it needs 208/240 VAC 3 phase
power. It can be re-wired to single phase a number of ways. A static phase
converter is the cheapest and since you are probably not planning on running
this for hours is perfect. You can build your own or buy
one from Grainger.
For anyone that has never seen one of
these up close, this is probably the loudest things you will ever hear. It took
me 6 tries to get video of it because the camcorder was to close and would shut
off when the horn would aim at it. Even with ear plugs and earmuffs the sound
is defining and you feel it throughout your body.
The siren consist mainly of three parts.
The chopper, which is the piece on top with the horn. It can
run on 120VAC single phase and is really a variable voltage motor. The control
panel has the ability to feed it different voltages.
The rotator, which is in the box under the horn. It runs on
120 VAC and is just a normal low HP motor meant only to turn the horn.
The blower, which is the big box at the bottom. It has a
mechanical blower that is belt driven by a 7.5HP 208/240 VAC, 3 phase motor. In
all reality you can replace this whole piece with a regular blower motor from
an inflatable slide or something similar. I used a leaf blower for testing purposes. The
siren will not be quite as loud but the more air you supply to the chopper the
louder it gets. This is the only part that needs the 3 phase power and pulls a
lot of current. So if you can find a blower that fits your power requirements
then you don't need this part and can run it off of regular house voltage with
some modifications to the control panel.
If you are wanting shipping on this, you will need to
