I just looked up on the Moore Oklahoma outdoor warning system map that the thunderbolt siren is siren number 25 and the federal signal 508 siren is siren number 44

Nice video! The 508 and the Thunderbolt harmonize well together!❤️
I distant recorded that along with 2 other Modulators today. Nice!
That's a whole lot of sirens! Nice one!
Is it replacing any siren?
@@jonathanboyd9644 It’ll be the replacement for the Thunderbolt eventually.
