Mystery siren

[holler]

Could be an old horizontal federal. Most of them had 15 port rotors on both ends.

Mexico uses 127V, 60 Hz. household voltage but has a variety of voltages available for large motors. Elektro-Kn?diger sirens were Czech-built sirens (I believe) that were used in China. I believe they were dual-toned, but no European sirens are made with this high pitch. The only sirens I have seen in Mexico were American ones, such as a Model 5 in Veracruz and an STH-10 on a factory in C?rdoba (where this video was taken). Any old Sterling with an insufficient power supply will sound like this, and anyone can build a roof over a siren.

Oh... I never really knew how high pitched the Elektro's were. I just thought that how in the video, the siren has a cage like amplifier and its weather shield.

I doubt this is an Elektro. I don't think any of those made it to the Americas. I believe that the Elektro-Kn?diger had a 10/12 configuration.

In that case the Elektro is cut right out of the list... What could it be...?

Well, like I said..I honestly think it's a 2001-130, then yet again, I could be wrong.

You might be right, maybe Mexico gets custom built sirens...?

Unless there is some Mexican siren builder I've never heard of, it can only be either a Sterling running a little slow or a 15-port Federal or Mars horizontal unit.

I have never heard a Sterling siren sound like that. To me it sounds like a 2001-130..... kind of reminds me of one of my first videos I posted on youtube....you all be the judge to comparing the sounds....link below
