I can understand why they would purchase a new siren that has only AC use (I.E. 2001*AC, Eclipse*8/NH*AC, ect. ect.)
Like these sirens here in South Dakota & Minnesota.
County: Lake. Town: Nunda. Siren Company: Federal Signal Corporation
Siren Model: FSC 2001 SRN*B AC. State: South Dakota


County: Minnehaha. Town: Dell Rapids. Siren Company: Federal Signal Corporation. Siren Model: 2001*DC AC.




County: Yellow Medicine. Town: Canby. Siren Company: Federal Signal Corporation. Siren Model: 2001 AC. State: Minestota.

Well in this option, a town, community, county that orders its siren(s) with AC power only, will have the ability to add the DC package sometime later if they wish to have the DC option.
AS you can see these are the only ones that I've seen with the AC package only deal.
Rather interesting in my option
What do ye think about this option?
