Found a Google Maps image of one of Kodiak's Alertronic AL-4000 sirens. It isn't an actual street view image taken by Google themselves, but a panorama image taken by a Google Maps user.
Here it is:

I really liked the way they sounded in that video, I attempted to locate one on "Streetview" but as you know it is an odd set up with the streetview in Kodiak. Very cool and good work!

There are many.
Here are the sirens going off for a tsunami warning:

It's one on a newer ASC controller. It's the same digital controller they use in their newer sirens except ASC set it to dual tone. When ASC wires their siren heads they tend to send the audio from the one or two amps through one side of the array. In this case the person recording the video happened to be on the side of the speaker wired to the low tone side of the amps. You can hear this with the I-Force 1600/STi-1600 in Hawaii. ACA wired the older Alertronics in such a way that that the drivers behind each horn were wired up to different amps. One driver carried the high tone, and the other carried the low tone. I think that's why they always sounded so raspy and rough.

After digging around, I found a map of their sirens, and I decited to map them all out on a google map a while back. Apparently they have 16 of them.

In this video at 1:16, you can actually see one shortly after it shuts off. It's the black thing on the pole.
