FS Model 5BT & Darley Model 2 | Alert & Short Attack | Chrisney, IN (Tornado/Fire Siren Test) 

The audio makes it feels like I’m literally there with you! I love your videos man! You’re a HUGE inspiration! Beautiful video as always!!

Wow! I was just thinking about this duo the other day; good to hear them running strong!

Awesome! One of my favorite siren videos redone. Also the drone shot is awesome!

The best siren duo in existence

_Like Father, Like Son_ Another superb recording.

I remember seeing the first video of these two ages ago and I still find it amusing that the 5BT and Darley M2 are portrayed as a dad and his son by the comments, wholesome.

boy be learnin from he dad

Still looks brand new! I still remember a video being made on this about 11 years ago! Surprised it doesn’t have a scratch

Beautiful video as always. I love hearing the radio chatter along with it. The drone shots always make it, too.

They're still there!!!!

You recorded it again?! Thats awesome!

This has to be the best recording of these sirens on RU-vid! Great job with the video!

Very nice! I like how they are both mounted! 👍

5BT be sounding creepy!! It also kinda sounds like a German Elektror F2 if it were dual tone!

When I put it on on full volume it's like I'm with you

its like its his father and his son lol

Nice

That model 2 sounded like an old police/fire truck siren, wow

Quality video thanks from UK

The Model 5BT Sounds like a T-128

So lemme guess...the Darley Model 2 is for fire calls?

The 5BT looks amazing but it sounds sick tho…. Why is that?
