The Cyclone was an omnidirectional siren produced by Alerting Communicators of America (ACA) and came in 2 models: The Cyclone 120 and 125 which superseded it. The Cyclone is a 8/12 port siren. All variations were able to be fitted with a damper which would be used for local code signalling. Examples of the Cyclone sounding these signals can be seen in the ACA promotional videos which are up on YouTube.
