As far as I've known, the protocol for Franklin County has always been 3 minutes on and 7 minutes off. In the past, the PA function was used in all 4 directions during the 7 minute pause but that's been eliminated. The county ran into problems on August 25th of 2007 when they literally ran the sirens with maybe a 10 second pause between cycles for the entire warning. I'd be interested to see what the new protocol is.
Also, what's interesting is that Whelen doesn't make any mention of a cool down period in any of their siren manuals.
Edit: I'm thinking they haven't yet changed the programming in their system. They basically hit a key and it runs a full tornado warning protocol until it gets cancelled (3 on 7 off). A few weeks ago, that key was accidently hit and instead of the normal Wednesday test, it ran 3 on and 7 off 3 times before it was cancelled.
