I found a promotional video of ACA's sirens on YouTube. To my surprise, i found footage of a Cyclone 125 being tested at the Maine Yankee Atomic Power Plant! In addition, the video mentions the quantities and types of sirens that were sold to Three Mile Island, New Jersey Public Service & Omaha Public Power.
Test starts at 8:52

This video might have already been posted on the board, but i am thrilled to see footage from my state to have been featured in their promotional video!
