As some of you know Los Angeles has well over 200 sirens. some notable models are FS model 5/7's, FS SD-10's, FS 500 SHTT's. It probably has the most well known civil siren system.
There is also a few B&N mobile directos, and one or two FS 2T22's. Also, there is some mystery siren that looks like a flower for some reason. Here is an image of the "flower" siren:

The siren pictured is a Federal SD-10. This was an artwork installation that was installed on this unit to make it look more visually-appealing. Here's a video regarding this:

In Los Angeles, there are a few sirens that many people think are H.O.R. siro-drones, but they are acually cutdown Fedelcode mach. 5/7's. The reason why they are cut down was to save medal. Here is an image (the image is not mine) of the "cutdown" Fedelcode:

I do not know how to add a link to my post. Also, it could have been in the video where Conner Cruz, a 3D siren seller, was showing his LA siren pack.
Edit: I think it was in siren walk #12 when the cutdown siren was talked about, but I could be wrong.

What platform is this on that you can’t just copy and paste in a web address?
