Automatic vs Manual transfer switch regarding 9.6.4 NFPA 20

Item 9.6.4 on NFPA 20 states the following:

 

" (F) Transfer of Power. Transfer of power to the fire pump controller between the individual source and tne alternate source shall take place within the pump room.".

 

It doesn't mention anything about the type of transfer switch (manual or automatic).

I know it makes more sense to have it automatic, but is it a formal transgression to the code having it be manually operated? Is there any other section, topic, standard that states it has to be automatic?
