ARCHIVED: Mystery Sirens (2008-3/2021)

[turtlbrdr]

Now that I've taken a look at the OmniAlert's specs, it would surprise me that anyone uses them at all. It makes sense why I haven't seen one until now. The range is pitiful.

Regardless, I did find that rotating whelen. About 1.25 miles to the south.

IIRC the OA1 is still rated for more range than a model 2.

Me and Lily were wondering what this is. It's located in downtown Portsmouth, NH on top of a building. Is this a siren (possibly a HOR, Decot, or a Erick) or a vent? The photo of it was taken by Lily.

I am certain it's an HOR Siro-Drone. It looks like one I have seen somewhere before... Cant remember where though. Maybe on the siren archive?

I believe it's on a HOR advert that I saw on Ebay

Got another two for you guys:

One looks like a WPS 4008, but I have no idea. It doesn't have the "shroud" the 4008 is supposed to have.

The other one, I have no idea

It's an old Whelen WS 3016. Moving the view over a bit and you'll be able to see the 16 horns.

The speaker looking things below I'm assuming are probably some custom thing?

A DSA array maybe?
