ARCHIVED: Mystery Sirens (2008-3/2021)

1955 to some unknown time and then 2000 to 2005. The STH-10 doesn't appear on Federal's website before 2000, yet the 2001 series does.

Perhaps they were phased out with the RSH-10s? When was that?

I'd guess so, along with the STL-10.

Hey I know this is an old topic, but i found this image online and couldn't find out what it is. I think its a square horn sentry siren, but what do you think?

No they did not. They phased out the RSH-10 before the STH. I know of at least two STH-10s that I maintain that were made in 2000.

To me, it looks like a Federal Model 5 with a Darley 5 lid and home-made horns fitted below the second 'skirt'.

Does anyone know what these sirens are? All I know is that they were installed recently, so they must be a newer model.

Those are Whelen Hornets, originally meant to rotate they consist of a single 400W driver. That's so awesome.

Is it just those two, or are there 1 or 2 more?

One mean PA system. 8) The model of the speaker in particular is the WS400H. There's a Whelen somewhere out there that uses them with a setup similar to an EC-4 to replace the head of a WS-2016.
