This is an ACA (Alerting Communicators of America) Banshee 115 tornado siren, located in Sussex, WI. This is not the Banshee that had the weird seizure many years back, as that one was located at Prides Park in Sussex. This one is located by the Sussex Fire Department. It is 8 port and uses a Compulert. It tests every Wednesday at 2PM from April to September and the 2nd Wednesday of each month at 2PM from September to April and should also go off every SWA day and whenever a tornado warning is issued. I'm happy to know that this thing still works good! By the way, this is the 1st of 2 batches of photos that I got of this siren today.
