I thought I'd start this new thread because Dane County is giving Madison a huge upgrade on the sirens that's scheduled to be completed by next spring. According to this proposed map which I'll post the link below will show all the sirens planned on being replaced or upgraded which I counted 20 replacements.

The HOR Super Sirex seems to be the only older siren to still be intact and left along. The rest of the older sirens (not sure about the three Model 7's near Monona though) are planned to be replaced. I don't know what the replacements will exactly be but looking at the range sizes for each of the new sirens, 6 will proably be 's or Equinox's or a mix of those two, 8 will be either 508's or T-128's, or a mix of those two, and the other 6 will most likely be :eclipse: 's
As for the other towns in the county including the Allertor in Cambridge and the :3t22: in Cross Plains, and maybe the Perf+Penetrator in Mount Horeb might be replaced too. However I highly hope the Perf+Penetrator stays as the only six of those ever made were in Dane County and the other five were already replaced.
