Since I am pretty brainy on it's topic, Trojan NPP had the most unique NPP system. It was diverse with Federal Signal sirens until 1984 and 1987 when PGE trickled in some Whelens into the mix. After both of the purchases and installs, the final siren count was brought up from 186 to 191. The sirens ...

Yeah I was about to say. TMI decommissioned back in September of 2019.

During the CSEPP program in Umatilla, their system was tripped on many various occasions, the most notorious occurring on Dec 31, 1999 IIRC.

There was this one US AFB around Afghanistan if I recall correctly? They had a system of Whelens and WAVES throughout the base.

Thanks for the location! I wouldn't be surprised if the siren is used for the nearby Fire Department. The department itself has a small micro-siren mounted on the far right corner of the station, but I hardly believe it has any use.

Of course! 2T22.

Removed.

Alaska has a fairly similar system to Washington state's AHAB system - a system of Modulators sprinkled throughout the coastline.

The Washington DC area had a few of these before they were phased out.

My pleasure!
