A nursing home in West Yorkshire I visited had a US system with pull stations like the one in the above pictures and a large conventional panel with bulbs (not LEDs) and appeared to be 20-30 yearas old in line with the building. UK style bells were fitted and non descript AFD.
It was in the middle of being replaced by a UK addressable system and running parallel to it. Its the only time I've seen US stuff over here and in such as unusual location - there was no apparent connection with a US company or agency, unlike say a building on a UK located US airbase for example.
American stainless steel stored pressure water extinguishers have been used here for years & were the first example of such before we made them ourselves. Particularly popular was the Badger Fire water, brought over by Thomas Glovers and seen re branded by major suppliers such as L&G, Thorn/Kidde Thorn etc. BHS stores had L&G labelled Badger waters in service for over 20 years (the same extinguishers, never needed replacing & wouldn't now if it weren't for the 'must be red' con). And of course after Badger the next most prevalent stainless water was the Amerex.
Now most stainless waters are Chinese - even the TG/Chubb ones.
