The Siren Board

Actually it probably doesn't reduce the sound any at all. It disperses the sound on a vertical plane instead of a horizontal plane. Meaning that anybody on the street nearby will get blasted.

I wonder why they have 3 sirens instead of just one...is the Whelen a backup for the Mobil Directo, and the Modulator for weather? None of that would make sense in the first place, though...

It's a Mobil Directo. Anyways, the top horn was turned verticle because of noise compaints.

They had noise complaints 60 years ago in 1953 when the siren was pretty much new?

It was more likely turned vertical to direct the sound wave up over the hills.

I believe that the Modulators are used for tsunami warnings, the Allertor was used for in-town fire calls, and the Whelen was used for fire district calls. As of July, 2013, both older sirens are no longer active. Here is the site in that photo as it looks now. The sirens are just out of the photo at center-left.

Why not just use one siren for everything?

I don't know. Over in Skagway, the fire department has an Allertor and FOUR diaphones on the hose tower.

Is the Mobil directo 10/12 port or gas to electric converted 8 port?

From the picture, I can say its 10/12 port.

I am standing across the street from these sirens at the moment. Currently the Mobil Directo and the electronic one are no longer in use. Only the Modulators are used for tsunami warnings. If you're a collector, give the Seward VFD a call.
