I know some of you out there are very knowledable about outdoor sirens and public warning systems, and ever since I was a kid I've gone to my grandparents that live near millstone nuclear power plant in CT and have seen these enormous electronic sirens atop telephone poles. Recently I have done research on both pneumatic and electronic sirens, looking at hundereds of different types and manufacturers, but I could not find the manufacturer or exact name for the (very ominous) sirens I have seen. I know they are some type of DSA, but I have seen about 20 sirens in different locations, and they all have different numbers of speakers, ranging from 2 to 5. These sirens seem to be getting replaced by the whelen WPS 2010, although these siren's appearance looks brand new. If you know any information about this siren or its manufacturer, please leave the info in comment form. Your help is greatly appreciated, and sorry for the boring movie.
