Vortexofmisery, more than most likely they are waiting on parts for the existing siren and not a new siren. A replacement siren from Whelen would take a couple of months to be delivered. From what I've been told, Whelen doesn't stock sirens. They build them when they recieve orders for them. I don't know how true this is, just what I've been told.
Again, though, where is this "downed" 3016 siren located??? From the aerial shot, it sort've looks like the one along Clarkson Road in Clarkson Valley.
