Well I haven't really got a good wind up to wind down of the sirens here, so I tried today. All went well except for the Model 5 not going off (I believe). Compared to my April tornado warning video, its pretty quite without that Model 5 blaring away. Sirens heard in this video are a Thunderbolt 1000, 2001 and a Thunderbeam RSH-10.
