Siren test 10 7 09 4/5 port Thunderbolt 1000T Cincinnati,Ohio

October of 09 siren test. This is the Thunderbolt 1000T on top of the fire station at Junietta and Epworth Avenues in Westwood. The video quality is not that great I had terrible glare from the light angle. To me this sounds like a 4/5 port.
