Seward, Alaska FD – Plethora of Sirens

[AST128_RyanK]

I found this image of the Seward, AK Fire Department with three sirens:

Whelen WS-2016
B&N Mobil-Directo
Federal Signal Modulator

This is actually a pretty popular subject, I'll link up the information about it soon.

The Mobil-Directo is fixed in one position, facing away from the downtown toward the harbor, and is only used as a noon whistle. The Modulators are used for tsunami warning, and the Whelen, I believe, is no longer used.
