I didn't take the picture but will try to get a picture of the rotor sometime

Posting this on behalf of the current owner, the motor may be shot but it is still around!

Here is an original ad for one

The controllers for the old ones went on eBay. I believe there were 5 of them on there, I was able to get one before they quickly sold, didn't even know it was from TMI until it came in the mail!

Here ya go! The only things I added to it are the air line fitting and bushing. Running it on a 20 gallon compressor at 120PSI this thing is pretty loud!

I tried it and it does work with compressed air however it's not loud at all compared to with CO2

Even though I have been trying to sell a lot of my sirens I found this on eBay the other day and couldn't pass it up. It is a 6-port Kidde CO2 powered fire suppression siren. Before a CO2 fire suppression system would discharge this would go off beforehand to warn of the impending release of CO2 gas...

My S-10 end table

Probably came off of a fire truck or an ambulance. Being 24 volt maybe a military vehicle

VS stands for Vehicle Siren, I own a CS3 which stands for Coded Siren and a GP1 (GP stands for General Purpose). Sorry but that's all I know right now.
