Sirens In LA

[Ryan]

Yep, as the title says, I have seen sirens in Los Angeles.



Before anyone asks:

I have no idea what make/model it is.
No I don't know the testing schedule (nor do I really care).
I have not heard it go off in the three months I've been living in LA.
Yes that's an LA Metro bus in the picture.

It looks like a Federal SD-10, probably installed during the 1950s. There are several in the Los Angeles area.

Here's an old site that documented many LA sirens:

That siren is an old Federal Signal SD-10, and those siren's have LONG since been deactivated; and it makes sense that you have not heard them as (I think) they were deactivated sometime in the mid to late 80's. Other siren's in LA include older short-horned 500T's, Model 5/7(T)'s, and some weird mystery siren's that look like a smaller Model 3.

The mystery sirens are Fedelcode 5s with short A-frame housings.

Ah, that makes sense. Thank you for the clarification!

https://www.google.com/maps/d/viewer?mi ... 8&hl=en_US Found this about a month ago, maybe you can see street view and see which ones were removed and not, but some place along the line of doing research, I think the siren system was cut long ago. Also, they have a Chrysler Bell Victory or 2 still up and caged

All 500Ts are have a short projector. The 500s with the longer projectors are: 500-SHTT, 500A/500B, 500AT/500BT.

Weren't there also a few Scream Master sirens down there?

There's even some 2T22 Or 3T22 sirens in California also. If you look carefully you notice that there's no power lines going to any of the sirens. When I first saw couple of California Civil Defense sirens pictures I thought they did still have power lines going to them. But it turned out they didn't.
