The Siren Board

As mentioned by other board members, there isn't much info on San Diego's Civil Defense Siren System. Growing up in San Diego, I can tell you the system was modern and very extensive throughout the city.
Sirens were tested at noon each Monday...While there are no still photos of the sirens, I have found film of several on the City of San Diego Digital Archives website.
Once there...proceed to Film and Audio section...then go to Street Videos (1970's)
This is a very extensive collection of camera car videos from the mid 1970's.
If you go to the University Ave Westbound video...you will spot a siren on your right at about 1:40 into the video. Other street views also pick up sirens...but this is a good look at one.
By the time this video was taken the sirens were no longer tested...and a few years later disappeared. These sirens were complete units...yellow...metal pole and working platform next to siren.
They were located all across the city. I don't know enough about sirens...but I am sure many of you will instantly recognize the type and make....

At 1:42 the siren is clearly visible, it is a Scream Master siren. They were pretty much exclusive to California.

Yes, that’s a Scream-Master, San Diego’s civil defense system isn’t well known as stated in the first comment, the only other siren i’ve seen there was an STL-10

Do you know where the STL-10 is located?

San Diego touted having 30 Super Sirexes as well. This is the largest undocumented system in the United States as of right now.

There's a GCS Model 3 in Vista that is rumored to have been a civil defense siren

What the hell? Lived around there for years and never knew!

It's located at the Sutton tree services building, formerly a fire station
