Possible Old L.A. Siren still in use?

When I was working on my U.S. Siren Map, I was marking an old Federal Sign & Signal 500 in Los Angeles. I couldn't see it on arial view, so I went to street view. I dropped next to the siren and it was facing NW. I went to the intersection and saw it was facing West. I looked at the wires and they weren't cut like the rest of them. Can anyone helpp me? I'm confused. Thanks!

This is what I saw first: https://earth.google.com/web/@34.228143 ... NBSF94dxAC

Then what I saw at the intersection: https://earth.google.com/web/@34.228313 ... RZYWRwZxAC

You can clearly see that it changed directions!

The belts on a lot of these either lost tension or broke, I don't think any of the old CD era sirens are still used.

Considering how tight Cali can be with some of their laws it would surprise me if they did.

All of the sirens in that particular system are not in use and haven't been in decades. This is also a Federal 500 siren, which is notorious for belts loosing tension/breaking, then waving in the wind.

There are a few videos of them moving in the wind.

They pulled the plug on those sirens around 1983. Yes, the rotator system on those seemed to be very troublesome.

I assume the same thing happened to the the one on Hillrose street, moved before January 2021.

Yes, likely the rotator belt has lost tension and or has broken and the siren is rotating with the wind.

The ONLY LA siren still in use is a model 7T on Catalina Island. The town of Avalon uses it as a fire siren.
