I should visit this one again on a test day to see if this persisted and look for that sticker. I've seen in the city's plan that they are planning to replace a couple more sirens in town, including the 2001 by Dairy Queen on the south side, closest one to where I live. Hoping to get pictures or vid...

I just realized I put a bad title on the topic. The 508 is fine, it is just the 2001 with the rotator issue.

Don't know offhand when I recorded these except the one was a drill day. Sorry for the shot of the car vent in that one, as I was en route when they started the sirens. The FS 2001 at Carmen and Waushara (near Walmart) in Marshfield was replaced within the last year or so with a FS 508. https://yout...

sounds like a chopper setting of 1 or 2.
EDIT, after seeing a comment on the youtube side, I amend myself. I was hearing a low tone, but on the wind down I heard the high side. Setting 6-7.

that echo reverb is epic.

when do they test and where is this one? I'm gonna be in the area later in the summer and would love to see this beast in person.

rotating pretty quick too at 5 rpm.

whoops. fixed it.

The description pretty much says it.
