Is this a P-20?

I've never heard this siren before. Someone on YouTube suggested that it's a P-20.

It's definately a penetrator... not sure of the exact model.

It doesnt sound like the p-10's and rm 127's we have in tuscaloosa. It has a higher pitch.

yus. That's a P-20 siren. AKA RM-130. I'd guess it means Rotating Mechanical siren and 130dB at 100 feet. Nice sirens. We don't really have too much information on them, unfortunatly. I've seen one in person. I thoguht it was an early T-128.

Nice video, Jerry. Nice to see another Wisconsinite here.

How many RM-130's does Fond Du Lac still have? I've only spotted one so far.

Menomonee Falls, WI has a bunch of these, too. I've only ever seen two of theirs in person, though.

It sounds like the rotor on the P-20/RM-130 turns at about 4000 RPM's. Is it belt driven?
