Fire Pump Power Source

I have a hospital that is not considered a high rise facility that the Joint Commission is telling us that the Fire Pump needs to be connected to the Generator per 2005 NFPA 99

2005 NFPA 99:
4.4.1.1.7 Uses for Essential Electrical System.
4.4.1.1.7.1 The generating equipment used shall be either reserved exclusively for such service or normally used for other purposes of peak demand control, internal voltage control, load relief for the external utility, or cogeneration. If normally used for the other purposes listed above, two or more sets shall be installed, such that the maximum actual demand likely to be produced by the connected load of the emergency system as well as medical air compressors, medical?surgical vacuum pumps, electrically operated fire pumps, jockey pumps, fuel pumps, and generator accessories shall be met with the largest single generator set out-of-service. The alternate source of emergency power for illumination and identification of means of egress shall be the essential electrical system. The alternate power source for fire protection signaling systems shall be the essential electrical systems.

I am saying that this just indicates that if you are connecting your fire pump to the generator you need to follow this.
But 2005 NFPA 99 also states in 1.1.4.1(4): that the requirement for Fire Pumps are covered in NFPA 20.

2005 NFPA 99:
1.1.4.1 Areas Not Addressed in Chapter 4 The following areas are not addressed in NFPA
99, but are addressed in other NFPA documents:
(1) Specific requirements for wiring and installation on equipment are covered in NFPA 70, National Electrical Code.
(2) Requirements for illumination and identification of means of egress in health care facilities are covered in NFPA 101, Life Safety Code.
(3) Requirements for fire protection signaling systems. For requirements for signaling systems, see NFPA 101_, Life Safety Code_ [6], and NFPA72_, National Fire Alarm Code_ [7].
(4) Requirements for fire pumps are covered in NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, except that the alternate source of power shall be permitted to be the essential electrical system. For requirements for fire pumps, see NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection [8].
(5) Requirements for the installation of stationary engines and gas turbines are covered in NFPA 37, Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines.


Furthermore NFPA 20 States in 9.3.1 that an alternate source is only required if the height of the structure is beyond the pumping capacity of the fire dept (i.e. A high rise) which we are not dealing with in this case.



9.3 Alternate Power.
9.3.1 Except for an arrangement described in 9.3.3, at least one alternate source of power shall be provided where the height of the structure is beyond the pumping capacity of the fire department apparatus.

9.3.2*Other Sources. Except for an arrangement described in 9.3.3, at least one alternate source of power shall be provided where the normal source is not reliable.


Just wanting to bounce this off of someone who may have dealt with it before.

Thanks,

Ed

For the most part NFPA "codes" are really design/construction standards that are not mandatory until an Authority Having Jurisdiction adopts them by reference, usually with some qualifications or ammendments. Check your state codes, which may state that a given system is required, and shall be designed per NFPA XX. In other words, the state code(s) state where systems are required, and NFPA defines how these systems are to be designed/installed/tested and used.
