Deep-toned siren in Poland

[Daniel]

Here is a pre-war, deep tone (tiefton) siren in use in Poland by their national fire service (OSP). It is probably German, and it appears that both tones heard are coming from a single, twin-motor Elektror siren with both motors wired together.

Sounds like 3/9 ports on 50hz

That sounds cool. Wish we had close up photos of one.

It probably looks like this one:

Judging by all the video titles it's called an OSP.

OSP stands for "Ochotniczia Straz Pozarna" which means volunteer fire service.

Very interesting siren.

Sounds very different from a t-bolt or 2001 8)

Could it be 2 separate sirens? Like the higher tone could be a toshiba and the lower tone could be something else?

It would be weird if it was electronic since I doubt the speakers can take that low tone, but to me it sounds like 2 different wind ups.

That doesn't mean you're right.. that's just a single tone siren

If you listen to Daniel's videos you will hear that they do not start at the same time. Maybe its just two separate siren?
