Triple Siren Setups

Pictured below, we have a Thunderbolt, a Sterling M, and Sterling Little Giant in the bottom left corner. I am not sure about the current status on these.

I checked the Bolt out on Streetview a few months ago, and it hasn't roated since that picture was taken. It would seem like all 3 sirens are inactive due to their condition on the most recent imagery.

Seward, Alaska. Posts from my search results indicate that the Mobil Directo was removed at some point.

I’ve seen that before, not in person, But on street view. Weird how it was sideways.

Let’s not forget about this one at the Federal Signal headquarters. It was a triple siren setup until the 508 was installed, making it a quadruple siren setup!

I thought a DSA was installed on the Modulator a couple of years ago.

It’s quite possible, but this was the first photo I stumbled across through my search, and I don’t keep up with everything on this forum like I used to.

Fun fact: one of those sirens at the Federal HQ is on an old Thunderbolt pole. I forget which one though.

I believe this is the Modulator pole with the old Thunderbolt tubing.
