The reverb coming off the hills gives a great indication of how loud these things are!
I live in Norfolk and grew up with one of these sirens on my doorstep.
The Norfolk flood warning signal is a 30-seconds on, 15-seconds off signal.
What is interesting is that your flood warning is very reminiscent of the WW2 Air-Raid "Attack" signal, consisting of shorter interval on/off sequence, but finishes with an incomplete "on" signal... interesting stuff!
@djoska87 I believe that the flood sirens in Essex and Norfolk date from the Cold War, so a seperate signal had to be used for floods. On the other hand I have read the sirens around Todmorden were upgraded in the early 2000s, by which time of course the "attack" signal was pretty much redundant
@djoska87 Yes my point was that for newer siren networks such as the one in this video, a seperate "flood" and "attack" signal is (hopefully!) no longer necessary, whereas the old Norfolk/Essex networks were designed to give both signals.
It's true that the one in this video is virtually identical to the old attack sigal (4 seconds on 4 seconds off).
Not quite sure when the sirens in Norfolk were first used for flood warning purposes, but I know they were handed over purely for that purpose following the end of the Cold-War scare in the early 90s.
I should be getting my hands on one or two soon...
This is arguably the best UK siren recording out there to date. Thank you so much for recording this! It sounds pretty close, and there seems to be a number of sirens in the distance.
@cauberallies You're welcome. Thanks to another youtube user, ive found out where the sirens are located in the town. I'm about half a mile from the closest one, and there is 3 of them dotted about the town
Wow- the sound is almost surreal!

@nwobhmrobert yes, but it is still a very similar signal to the WW2 "attack", especially to the un-trained ear...
Norfolk's sirens are being taken down as I write this...

You should really try and get up close to it if you can come the next test. It would be nice to see what model it is!
