Just some more for you
Rolls powered 757-200's Cargo mounted bottles, 2 off shared by both engines.
Rolls powered 767-300's Nose cowl mounted 2 for each engine.
Airbus A319,A320,A321 CFM and V2500 - 2 bottles in each pylon, easy to change but you need flexible arms!! All pretty much instant.
Only thing i'm a little surprised at is all the above only have one APU fire bottle. If that fails to put out the fire you have no second chance.
