ACA Cyclone in York, Pennsylania (formerly part of the Three Mile Island system)

The Cyclone was a omnidirectional siren made by Alerting communicators of America in 2 models: The Cyclone 120 and the Cyclone 125. Once Alerting Communicators of America changed into American Signal Corporation, they continued making these 2 sirens. There were not very many made under the American Signal Corporation name.
