Questions about Sellafield's Alarms

I stumbled across the Sellafield facility's alarms from 2012, back when another company ran the site. This is what I'm talking about: https://www.youtube.com/watch?v=dtNgOeqBKQU

Considering that these alarms were from a decade ago, and that currently Sellafield is run by a different entity nowadays, what are the new warning signals, if they are any different at all? Certainly something has to had changed, since the off-site emergency warning is a group of train horns but according to the UK siren map the three sirens on-site are labeled as possible Klaxons or PA systems, could these be where the different sounds come out, or is there a chance of other megaphones around the outdoors portion of the site?

Bump. My Grandad works at Sellafield, and he says that the 'sirens' that are used there, in his words: "look just like giant speakers; they let out a really loud, droning noise, a bit like a foghorn". This could mean multiple things, but I will try to do a bit more research when I have more time.
Again, sorry for the bump.

I’ve asked my Grandad to ask the Sellafield staff about the sirens when he goes back on-site, so we could get some interesting information shortly!

Sorry for the bump… if y’all still aren’t yet 100% sure what the sirens in in this video at 34:44 you can see what is clearly a Hörmann if some sort, hope this helps
