That's my best guess. I really don't know though! High pitched and rotating but definitly not a 2001

Tulsa is Whelen territory. Those are WS 3016s both single toned and dual, and a 2804.

Whelen 3106 (I think) both Single and Dual tone versions.

[Joey P 3]

you can also hear the 2800...its the low tone sound

[ACAP10]

Ahh, a 3016 didn't even cross my mind. To my credit, they do sometimes sound alike

[ver tum]

That duel tone 3016 sounds a lot like a high pitched Thunderbolt! Was that the only dual tone siren Whelen ever made?
