Hello, back in December I went to Peterborough Ontario to remove the last air raid siren in there city. It was an Omni-directional CLM, the only one I knew of in Ontario left except in the Diefenbunker museum. It took me one day of calling to get permission to take it down (quickest permission I ever got). I got a crane company to come in, along with a tree climber to work together to take this beast down. After a couple hours I had the siren in the back of our van and on our way home. This is a single phase, 220V, 3 HP model. When it get a bit warmer I'm going to call a couple people up to help me flip it over and then im going to test it.

Congrats on your second CLM! I'd imagine the port ratio is 10/12, right? Not the 12/4 the rotating one was.

Yes it 10/12 port.

They're all 10/12, except the rotating ones have a partial rear stator.
Great job on acquiring the siren! That's a rather interesting-looking intake area, to say the least. The rotor and stator almost look like those of a Decot.

Siren_Dude, how do you do it? I've been emailing municipalities for years with no results. Well, there was one... in Mitchell, but you beat me to it!
Congrats
Just reading the article it mentions the false alarm siren event in the late 1970s at 430am in the morning. Years ago my mother told me about the old sirens going off in the middle of the night and scaring the living daylights out of everyone. She thought it may have been the 1980s, but now it's confirmed it was the '70s. Neat!

the rotating one was 10/12. it's the number of chopper ports that matters, not the stator ports.

Looks like Canada's version of the SD-10.
