WOW! What an odd looking Allertor.

[carexpertandy]

That's so pointless for a rotating siren. The sound probably doesn't get much louder when it points towards you.

[holler]

I think that's a Mobil directo. You can see the gearbox mounting flange in one of the pics.

[ThunderboltFan102]

MD for sure.

[LukeH]

I think it's a federal dunno what model though.
It's off Willow ave in Long Beach west of the 605 near the 405
the phone line is intact but the power lines were cut a long time ago.
I pass it going to work every day.

This is a Decot I believe.

That is a Decot siren.

here is a close up of one posted a while back.

[ThunderboltFan102]

They're exactly the same.

[holler]

No they're not. The one on the pole is much larger, and it's a single tone siren.

[ThunderboltFan102]

Oh.

[LukeH]

No they're not. The one on the pole is much larger, and it's a single tone siren.

If you look at the one on the wall. compared to the blocks that's got to be pushing 3 feet. Id say their both around the size of a model 5. And how can you tell the one on the pole is single tone?

[LukeH]

Did anybody ever figure out what this thing is?
