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. It is made mostly of brass with a steel grille. I believe a few others on here may have one of these but I don't believed they have been discussed in-depth before.

Yes, it's like a mini hurricane except using CO2 instead of compressed air. That siren actually won't work with compressed air.

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

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!
