Mystery siren

[MattDean1003]

Sounds like a Model 5 or an STH10....but it's in another country.

That is in Mexico and most likely a Sterling.

Good lord..that sounds just like an omni-directional 2001-130. Thanks for sharing!

EDIT: Honestly, I think that IS a 2001-130 sounding. The pitch wavers a bit in the video, just as if it was rotating. Even winds down at the same speed as a 2001, compared to another video. See for yourself.

Am I the only one who sees the siren on top of the building? Deinitly not a FS 2001-130

Yeah I see it too, but it looks like a Elektro-Knadiger.

In fact, thats exactly what it is.

Well obviously, lol. But.. why does it sound EXACTLY like one? I'll bet the 2001 is around the building or something..because I have never heard of a Sterling or any older siren that sounds just like a 2001.

Does Mexico run on 50Hz or 60?
If they run on 50, it's a sterling.

Mexico... 60Hz.

awwww, man!

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.
