The Siren Board

I am uncertain as to whether this was posted here before, but I thought it was cool enough to share. Me and TNT1001 years ago mapped Los Angeles by just randomly prodding around for sirens. Today however, I found the official siren location list, as well as circuit numbers, control point location, etc. I will be making a redux of the LA map using this list:

I'm unsure of the age of the list, however there is a hand written note on it dated March 14, 1983 about three sirens possibly being activated by "PT&T". What this is I don't know.

Pacific Telephone & Telegraph .... the phone service provider for that area

Don't mind me: just adding thread to "my posts" collection... no but I'm all seriousness that is super cool!

Nice! I just moved to LA I've passed by a few SD10s, I believe the ones off wilshire. Will definitely keep an eye on this thread.

Me and a couple of the guys are over on discord are working on remaking the old L.A. map using this map as a guide. Stay tuned for a post on that!
