An emergency generator serving just the pump or a generator serving
other/additional building needs (such as a hospital/Life Safety Code)
satisfies the requirement for back up to the electric motor driven fire
pump.
A back up isn't necessarily required by NFPA 20 unless your power source
isn't reliable or unless there are other considerations for the requirement.
Have I missed your point?

Subject: Fire Pump Alternate Power
NFPA 20 (2007) Article 9.3.3 states "An alternate source of power is not
required where a back-up engine driven or back-up steam turbine driven fire
pump is installed in accordance with this standard."
Does the use of an emergency generator serving only the fire pump (no other
power) qualify as a back-up engine driven fire pump?
