Public Input No. 63-NFPA 20-2013 [ Section No. 3.3.41 ]

3.3.41 Record Drawing.A design, working drawing, or Drawings. Drawings ( as-builtdrawing) thatis submitted as the final record of documentation for the project.document the location of all devices, appliances, wiring sequences, wiring methods, and connections of the components of the system as installed [72:2016]


Paragraph 14.3 refers to record drawings so the definition has been revised to be plural. It would be extremely rare that the design drawings could serve as the record drawings. The record drawings should indicate the as build (installed) condition. In searching for a better definition, it was noted that NFPA 72 already has a definition so it is proposed to extract the definition from NFPA 72. While there may be some text not exactly related to a fire pump installation, the definition still seems to be applicable.

16. Test connection piping and valves

17. Flow meter details (if used)

18. If a jockey pump is provided, include jockey pump and controller arrangement including with sensing line details

The intent is to clean up the requirements so that they are applicable to fire pump installations. The following changes were made:

1. The weight of the suction piping was eliminated because that is not important. How many pounds of suction pipe are present is not an aspect of fire pump installations that should be subjected to plan review.

2. The "valves, regulators, meters, and valve pits" were moved to their own line with "if present" added to them because they are not always included in a fire pump installation and they should not be limited to suction piping. The AHJ should get this information about valves regarding the discharge valves as well.

3. The "valve indicators" was removed because the type of valve will be included with the description and size of the valve. We should not also have to described the size of the stem coming out of the valve to indicate that it is open.

4. The water supply information in part (8) (except for item "I" which was dealt with separately) only applies to flow test information, so this portion of the list was clarified to show that it only applies to those situations where a flow test was run.

5. The "riser reference point" was changed to "elevation reference point" because a fire pump installation does not have a riser.

6. Item "I" was moved to its own item in the list because it does not pertain to a flow test. Flow and size information was added because this is an important point for items like tanks.

7. Voltage and fuel system requirements were separated to make them independent.

8. The term "if provided" was added to the jockey pump information because they are not always provided and you should not have to provide information on a jockey pump that is not present.

The whole section should look like the following (a legislative version will be provided as an uploaded file because the system messed it up completely):

4.2.3.1 Plans shall be drawn to an indicated scale, on sheets of uniform size, and shall indicate, as a minimum, the items from the following list that pertain to the design of the system: 1.

Currently there is no guidance or requirements regarding the performance of the attached water supply. Fire pump installers can perform fire pump testing when the water supply is under its least demand. There are instances where the water supply may be inadequate because the demand generated by other users. The fire pump test would fail; however, the pump test could be performed when demand for water is significantly less resulting in an adequate supply of water. The purpose of the pump is to supply water for the purposes of fire protection 24/7, 365 days per year, and it should be tested when the water demand is the greatest. This would result in a more accurate performance of the fire protection system and provide more accurate information for fire department pre-planning efforts where the water system may under perform.

In the event that the water supply is deemed inadequate the provisions of 4.6.2.3.1 and 4.6.2.3.2 would apply.

Public Input No. 125-NFPA 20-2013 [ New Section after 4.11.1 ]

Full flow of cooling water to the pump during churn in variable speed pressure limiting controlled fire pumpsWhere an electric variable speed pressure limiting controller is installed, the automatic relief valve shall be bypassed by a normally-closed, electric solenoid operated valve, permitting full flow of cooling water to the pump when the variable speed pressure limiting controller is running regardless of the discharge output of the pump. Energy to operate the solenoid valve shall be provided by the variable speedpressure limiting controller when operating in variable speed mode only.


When the pressure set point is satisfied during churn, the variable speed drive runs at a minimum speed which is often set at 50% of rated motor full-speed. Not enough pressure is developed at this minimum speed to provide adequate water flow for cooling the pump. This is a concern since the pump can be running in churn for a period of time during a weekly or monthly test for example. Outside of the variable speed drive, the problem doesn't exist since the motor is operating at full-speed during churn and is developing adequate pressure for flowing cooling water, unless of course, the relief valve isn't properly set.

Public Input No. 134-NFPA 20-2013 [ Section No. 4.12.2.1.1 ]

4.12.2.1.1Fire pump rooms not directly accessible from the outside shall be accessible through an enclosed passageway from an enclosed stairway or exterior exit , which is not part of a required means ofegress .


Access to a fire pump room should not be allowed to be from a protected exit enclosure. Protected exit enclosures are very important to the means of egress and should not be utilized for this type of equipment access. Any problems associated with equipment failure could jeopardize the integrity of the means of egress, as protected exit enclosures are dedicated egress paths. It appears that the allowance in this section of NFPA 20 conflicts with NFPA 5000, section 11.1.3.2.1.6, and also the IBC. These documents do not allow such openings into protected exit enclosures.

NFPA 5000, section 11.1.3.2.1.6* states: Openings in exit enclosures shall be limited to doors from normally occupied spaces and corridors and for egress from the enclosure, unless such openings are in exit passageways in mall buildings, as provided in 27.2.2.7.

NFPA 5000, section A.11.1.3.2.1.6 states: Means of egress from the level of exit discharge is permitted to pass through an exit stair enclosure or exit passageway serving other floors. Doors for convenience purposes and unrelated to egress also are permitted to provide access to and from exit stair enclosures and exit passageways, provided that such doors are from corridors or normally occupied spaces. It is also the intent of this provision to prohibit exit enclosure windows, other than approved vision panels in doors, that are not mounted in an exterior wall.

This revision would require a dedicated and protected access to the fire pump room, if there is no direct access from outside. This will ensure that during a fire, the fire department has good access to the fire pump room without the risk of compromising the protected exit enclosure. If the Technical Committee does not agree with this change, then consideration should be given to adding an exception for fire pump room access in NFPA 5000.

4.12.5.2 The minimum average horizontal illumination provided by normal lighting sources in the separate building or room housing the firepump equipment shall be 32.3 lux (3.0 ft-candles) measured at the floor level, unless otherwise specified by a requirement recognized by the authority having jurisdiction.


The level of illumination required by NFPA 101 for emergency light is an average of 1 ft-candle and, at any point, not less than 0.1 ft-candle. While adequate for egress purposes, the level of illumination is not adequate for a person to work in a fire pump room should normal power be lost. The level of illumination recommended in this Public Input is consistent with a Level 1 EPS room (per NFPA 110). The Committee might also want to consider requirement battery-operated emergency light units consistent with the requirements in NFPA 110. The Committee may also want to give consideration to the duration of the emergency lighting system. NFPA 101 would require a minimum of 90 minutes and would the lighting level to degrade from the performance stated above during that time period. Whereas the water supply duration and operation of the fire pump may be in excess of 90 minutes, NFPA 20 may want to require emergency lighting for a longer period of time.

TITLE OF NEW CONTENT4.18* Protection of System Components Against Pressure Surges.4.18.1 The operation of the fire pump shall not result in excessive pressuresurges4.18.2 When required to prevent excessive pressure surges, a means of surge suppression shall be installed.


NFPA 20 currently does not address the issue of pressure surges that may result in broken pipe and/or system components.









4.18.1.2 Where a diesel engine fire pump is installed and where a total of 121 percent of the net rated shutoff (churn) pressure plus the maximum static suction pressure, adjusted for elevation, exceeds 125% of the pressure for which the system components are rated, a pressure relief valve shall be installed. When installed, the pressure relief valve shall be set to operate at a pressure at orbelow the pressure rating of the system components adjusted for elevation.


Under current requirements pressure relief valves are installed to protect against the failure of a variable speed pump or diesel engine overspeed. It is preferrable to subject system components to a limited pressure excess rather than installing a pressure relief valve that introduces another failure mode. Currently systems may be hydrostatically tested to 50 psi over there rated pressure and pressure relief valves are allowed by the testing standards to exceed the set pressure by 25%. 125% of rated pressure is well below the component safety factor and is a reasonable overpressurization to avoid pressure relief valves.









4.18.1.3.1 Pressure relief valve shall be set at 10 psi above system rated pressure.4.18.1.3.2 Where the variable speed pressure limiting controller or diesel pressure limiting driver allows a pressure rise back to shutoff the pressure relief valve shall be set at 10 psi above the pressure at shutoff.

Instability of the variable speed pressure limiting control can occur when the pressure relief valve is set too close to the set pressure of the variable speed pressure limiting control.

4.18.2 Size.The relief valve size shall be determined by one of the methods specified in 4.18.2.1 or 4.18.2.2 .

4.18.2.1*

The relief valve shall be permitted to be sized hydraulically to discharge sufficient the minimum size that will flow sufficient water to prevent the pump discharge pressure, adjusted for elevation, from exceeding the pressure rating of the system components.4.18.2.2

If the relief valve is not sized hydraulically, the relief valve size shall not be less than that given in Section 4.26 . (See also 4.18.7 andA.4.18.7 for conditions that affect size.)


Failure of an oversized pressure relief valve will divert all or a substantial amount of water from the fire protection system. Proper sizing of the pressure relief valve would provide more water to the fire protection system with a pressure relief valve failure. In general, pressure relief valve sized in Table 4.26(a) are: 1 size to larger than required for pressure relief valves discharging to atmosphere, the correct size for most pressure relief valves returned to suction, but may be undersized for pressure relief valves returned to suction when the water supply has a high static pressure.

TITLE OF NEW CONTENT4.19.2.5 Fire pumps that operate in series that are not located in the same room shall comply with the following.1) No more that two pumps shall operate in series.2) Each pump shall be arranged so that it can be manually stopped or started from the other pump room.3) The suction and discharge pressures from each pump shall be displayed in the other pump room.4) All trouble signals from each pump shall be displayed in the other pump room.


Communicating between fire pump rooms is difficult. Operating pumps simultaneously in separate rooms requires one operator to know the conditions at both pumps. Low suction pressure at the remote pump should be responded to immediately to prevent damage to the fire pump. Remote operation capability allows a fire to act when possible, or warn firefighters that are depending on the water supply of abnormal pumping conditions.

A heat buildup will occur in the water when flowing water through a closed test loop and a circulation relief valve that operates at a lower pressure that the fire pump circulation relief valve is needed to provide cooling. Placing the circulation relief valve downstream of the metering device allows the metering device to show the full flow.

4.25.1 Pressure maintenance pumps are not required. When used, they shall comply with 4.25.2 through 4.25.4.




The addition of new 4.25.1 clarifies in the standard that the pressure maintenance pump in not required as indicated in A.4.25. It presently states: A.4.25 Pressure maintenance (jockey or make-up) pumps should be used where it is desirable to maintain a uniform or relatiively high pressure on the fire protection system.









4.25.5.4A check valve and isolation valve shall be installed in the discharge pipe. The check valve shall be installed as close to the discharge side of the pump as possible and as far away from the isolation valve as possible to mitigate water hammer in the discharge piping.


The mitigation of water hammer extends the life of pressures sensing devices in the jockey pump controller. Since the pressure sensing line should be connected to the piping as far away as possible from the check valve which is generating the water hammer, it is logical to install the check valve as close to the discharge side of the pump as possible.









4.25.5.6The pressure sensing line for the pressure maintenance pump shall be in accordance with Section 4.30 and shall be connected to the piping as far away as possible from the check valve .


Mitigation of water hammer generated by the check valve extends the life of the pressure sensing devices in the controller. The further away the pressure sensing line connection is from the check valve generating the water hammer (or spikes) the better.









4.27.4.6 Where a backflow prevention device is retroactively installed in the suction piping, all of the following shall be performed:

(1) Hydraulic calculations shall be performed to insure conformance with section4.27.4.2.(2) The location of the backflow device shall comply with 4.27.3.(3) Hydraulic calculations shall be performed to insure that the discharge pressure from the fire pump is sufficient to meet the demand(s) of the fire protection system(s) supplied by the pump.4.27.4.7 Where a backflow prevention device is retroactively installed in the discharge piping, hydraulic calculations shall be performed to insure that the discharge pressure from the pump is sufficient to meet the demand(s) of the fire protection system(s)supplied by the pump.


Retrofit of backflow preventers is common on fire pump systems. When the backflow device is installed on the suction side, we need to make sure that the backflow device does not impair the fire pump and that the backflow device will not impair the fire protection system. When the backflow device is installed on the discharge side, we need to make sure that it does not impair the fire protection system.

These same requriements are in other NFPA standards, but the scope of NFPA 20 keeps the suction and discharge piping out of the scope of other standards, so techncially, they don't apply. Therefore, these requirements need to be included in NFPA 20 so that they apply whenever a backflow device is retrofitted on suction or discharge piping.

8.5.3.1For foam concentrate pumps, safety relief valves shall be piped to return the valve discharge to the concentrate supply tank or to the pump suction.


This new section harmonizes the requirements for pressure relief valves for positive displacement foam concentrate pumps and positive displacement watermist pumps. Section 8.5.4 makes allowance for the relief valve discharge to be piped to the pump suction as long as a means of thermal relief is provided. NFPA 11 makes no such restriction on positive displacement foam concentrate pumps and illustrates piping the relief valve to the pump suction in Figures A.3.3.23.1 and A.3.3.23.1.1(a).

8.5.3 * Relief Valves for Foam Concentrate Pumps.For foam concentrate pumps, safety relief valves shall be piped to return the valve discharge to the concentrate supply tank.


Section 8.5.3 is inconsistent in its requirements with Section 8.5.4 for the same type of pump and is also inconsistent with what is required by and illustrated in NFPA 11. Sections 8.5.3 and 8.5.4 both detail safety relief valve requirements for positive displacement pumps but 8.5.4 makes allowance for piping of the relief valve discharge to the suction side of the pump. NFPA 11 states in section 9.1.2 that positive displacement pumps shall be provided with a means of pressure relief from the discharge to the supply side of the circuit. No location on the supply side of the circuit is specifically prohibited for the relief valve discharge to be piped to. Figures A.3.3.23.1 and A.3.3.23.1.1(a) on page 11-43 of the 2010 Edition of NFPA 11 both illustrate a positive displacement foam pump with the safety relief valve discharge piped to the pump suction, in direct conflict with Section 8.5.3 of NFPA 20. Positive displacement pumps for use with foam and watermist have no substantial differences and, frequently, the same makes and models of pumps are used for both applications. There is no sound technical reason for safety relief valves for positive displacement pumps used with foam concentrate to have different piping requirements than those used for watermist applications.

File Name Description Approvednfpapublicinputform_Kovacik2.docx Cover Sheet


The term “Listed fire pump power transfer switch assembly” was added to Appendix A of the 2013 Edition of NFPA 20, but not referred to in the body of the standard. Reference Figure A.10.8, Arrangement II. The intent was to recognize the use of a fire pump power transfer switch assembly which could include an isolating switch and overcurrent protection for the transfer switch in the same enclosure as the transfer switch. As a fire pump transfer switch is required to be located in the pump room, the overcurrent protection and isolating switch, when provided as part of the transfer switch assembly, would not be remote from the fire pump controller. When the subject of a transfer switch assembly was discussed during the last code cycle, it was anticipated that the overcurrent protection and isolating switch, when provided as part of the transfer switch assembly would not be the one disconnecting means and associated overcurrent protection device permitted by 9.2.3. In order to allow an additional disconnecting means and associated overcurrent protection device to be remote from the pump room in such installations, the added text is necessary.

This proposal is summarized as follows;1. Table 9.5.1.1 is being revised to correct values to represent current motor design and construction.2. Table 9.5.1.1 is being revised to add motors with three phase horsepower ratings not currently in the table.3. Table 9.5.1.1 is being revised and split into two tables, Tables 9.5.1.1 (a) and (b). Table 9.5.1.1 (a) will be the existing Table 9.5.1.1 (revised per items 1 and 2 above) and cover three phase motors. Table 9.5.1.1 (b) will be a new table covering single phase motors which are not currently covered by NFPA 20.4. Clause 9.5.1.1 is being revised to specify and differentiate the NEMA motor designs for three and single phase motors. 5. The source documents for values inserted in the tables are UL 1004-5 for three phase motors and NEMA MG-1 for single phase motors.

The following is background information relating to these changes.

1. There are no NEMA Design B standards for single-phase motors. UL 1004-5 does not cover single phase motors.2. MG1 has tables which lists the maximum limit on locked rotor currents for single phase motors. There are tables for small and medium motors. For the Design N (small) and Design L (medium) types the limit on LRA at 230 volts is NOT one-half of that at 115 volts.3. The values of locked rotor amps given in the tables in MG1 standards are upper limits.4. Design B performance standards for 3 phase medium motors in NEMA MG1 begin at a minimum rating of 1/2 hp. However, that is 1/2 hp at 900 RPM synchronous speed (8 poles) and slower speeds at 60 Hz. There are no NEMA Design B 1/2 hp motors in 2, 4, or 6 poles. Similarly, the Design B standard applies to 3/4 hp and higher at 1200 RPM (6 pole) and slower speeds (higher number of poles) 1 Hp and higher at 1800 RPM (4 poles) and slower speeds 1-1/2 Hp and higher at 3600 RPM (2 pole) and slower speeds. If a fire pump application requires the use of a 2, 4, or 6 pole polyphase motor rated 1/2 hp, it cannot be a NEMA Design B motor since such a motor does not exist.5. NFPA 20, Table 9.5.1.1 “Horsepower and Locked Rotor Current Motor Designation for NEMA Design B Motors” has errors for certain locked rotor amps and locked rotor code letters. UL 1004-5 has Tables with the correct values and should be used as a guide for revising Table 9.5.1.1.6. NFPA 20, Table 9.5.1.1 should be revised to add hp ratings below 5 hp. The lower limit should be 1 hp which is the smallest 3 phase NEMA Design B motor. 7. A separate table should be added to NFPA 20 for single phase motors. The range of horsepower ratings for the table could be 1/6 to 10 hp as there are published values of full-load currents for motors in this range. NEMA Design N single phase small motors exist only for 1/6 through 1 hp in 2 poles, 1/8 through 3/4 hp in 4 poles, and 1/8 through 1/2 hp in 6 poles. The upper rating in the range corresponds to the upper limit on hp for small motors. NEMA Design L single phase medium motors exist only for 1-1/2 through 10 hp in 2 poles, 1 through 10 hp in 4 poles, and 3/4 through 3 hp in 6 poles. It should be noted that for the Design N (small) and L (medium) types the limit on LRA at 230 volts is NOT one-half of the LRA at 115 volts.

This makes the installation much safer as it is very easy for a shunt-trip breaker to accidentally be placed in the "tripped" condition.

9.6.5 * Protective Devices.Protective devices installed in the on-site power source circuits at the generator shall allow instantaneous pickup of the full pump room load and shall comply with NFPA 70, National Electrical Code, Section 700.27. The fire pump circuit breaker is not required to be coordinated with the generator power source protective device provided it is a branch circuit and is coordinated with all other line side protective devices.




Before the emergency circuit breaker in the fire pump controller was required, there wasn't a breaker to coordinate with. Now that there is, the generator set may be forced to be larger to accomodate the 300% no trip setting of the fire pump controller circuit breaker.









9.7 Junction Boxes.Where fire pump wiring to or from a fire pump controller is routed through a junction box, the following requirements shall be met:

(1) The junction box shall be securely mounted.

(2)

(3)

(4) As a minimum, a Type 2, dripproof enclosure (junction box) shall be used. The enclosure shall be listed to match the fire pump controller enclosure type rating.

(5) Terminals, junction blocks, and splices, where used, shall be listed.

(6) A fire pump controller or fire pump power transfer switch, where provided, shall not be used as a junction box to supply other equipment, including a pressure maintenance (jockey) pump(s). (See 10.3.4.5.1 and 10.3.4.6.)

(7) A fire pump controller or fire pump power transfer switch shall not be used as a junction box for wire splices.




A junction box is the proper location to splice wires, not the fire pump controller or transfer switch controller. There isn't enough wire bending space for this and the additional cables may interfere with the maintenance and repair of the controller.




* Mounting and installation of a junction box shall not violate the enclosure type rating of the fire pump controller(s).* Mounting and installation of a junction box shall not violate the integrity of the fire pump controller(s) and shall not affect the short circuit rating of the controller(s).








9.9.5Where the raceway (conduit) between the controller and motor is not capable of conducting ground fault current sufficient to trip the circuit breaker when a ground fault occurs, a separate equipment grounding conductor shall be installed between the controller and motor.




Clause 9.9.5 was added to NFPA 2013 at the Comment stage of the process. Subsequently, I submitted a proposal for the 2014 NEC to include this same requirement in Article 695 which covers electrical installation requirements for fire pumps. At the ROP meeting, Code Panel 13 decided this requirement was not enforceable since there is no way for an AHJ to determine when a raceway (conduit) between the controller and motor is not capable of conducting ground fault current sufficient to trip the circuit breaker when a ground fault occurs. The Panel modified the proposal to require an equipment grounding conductor in all installations between the controller and motor (redundant grounding). The panel substantiated that if conducting ground fault current may be a concern with any installation, mandating the use of an equipment grounding conductor will remove that concern. At the ROC meeting, the Panel reversed its position and decided there is insufficient substantiation to require redundant grounding and decided to make no changes to Article 695 for the 2014 NEC. Based on the actions of Code Panel 13, it is proposed to delete 9.9.5. Further to this subject, it is questionable whether this requirement belongs in NFPA 20 as NEC Article 695 has responsibility for electrical installation requirements for fire pumps.











10.3.4.5.3 Unless approved by the Authority Having Jurisdiction, remote stopping or locking out of the fire pump shall not be allowed.




This has always been the intent of the committee based on past action, but is not stated anywhere in the standard.

(1)* For all pressure transducers relating to fire pump operation: Electronic pressure reading exceeding a preset high pressure value(2)* For a transducer in the automatic start pressure sensing line: minimum electronic pressure reading that fails to fall below a preset automatic start low valueduring automatic pump startup.(3)* For all pressure transducers relating to fire pump operation: Electronic pressure reading below a preset low value at any time except during an automatic startup.(4)* Any tine the transducer output is less than 10% of rated span below its ratedzero pressure output.(5)* Any time is more than 10% of it's rated span above its rated full scale output.(6)* For a variable speed motor driven fire pump controller: any time the output from the variable speed control transducer differs from the output of the start/stoptransducer by more than 5% of rated transducer span.(7)* For controllers equipped with weekly test start, when the pressure output is more than 5% of rated range above the rated zero output.10.5.2.1.8.1 When one of the conditions monitered in 10.5.2.1.6 occurs, the controller shall either activate a visual and silenceable audible alarm and activate contacts for a remote alarm, or start the pump.


Failure of the pressure actuating mechanism can cause failure of the entire fire protection system. The recent transducer recall revealed the potential for failure. Although the recall may have addressed the immediate problem, the potential for future failures remains and can be addressed. Mercoid switches do not have any supervisorable mechanism to verify failures prior to testing. Tranducers are continously interacting with the controller and can be supervised.











10.5.2.7 Automatic Testing.10.5.2.7.1 To ensure dependable operation of the motor and its controller, the controller equipmetn shall be arranged to automatically start and run the motor at the minimum noflow test frequency and duration required by NFPA 25.10.5.2.7.2 Performance of the AutomaticTesting shall be recorded as a pressure drop indication on the pressure recorder.10.5.2.7.3 A solenoid valve drain on the pressure control line shall be the initiatingmeans.10.5.2.7.4 In a non-pressure-actuated controller, the automatic testing shall be permitted to be initiated by means other than a solenoid valve.













10.5.3.3 Manual Testing of Automatic Operation.10.5.3.3.1 The controller shall be arranged to manually start the motor by opening the solenoid valve drain when so initiated by the operator.10.5.3.3.2 In a non-pressure-actuated controller, the manual test shall be permitted to be initiated by means other than a solenoid valve.













10.5.4.2 Automatic Shutdown After Automatic Start.Where provided, automatic shutdown after automatic start shall comply with the following:

(1) Unless the requirements of 10.5.4.2 (3) are met, automatic shutdown shall be permitted only where the controller is arranged for automatic shutdown after all starting and running causes have returned to normal.

(2) A running period timer set for at least 10 minutes running time shall be permitted to commence at initial operation.

(3) The requirements of 10.5.4.2 (1) shall not apply and automatic shutdown shall not be permitted where the pump constitutes the sole supply of a fire sprinkler or standpipe system or where the authority having jurisdiction has required manual shutdown.




This is the actual practice in the field.









10.8.2.2 Arrangement II (Individually Listed Fire Pump Controller and Power Transfer Switch).The following shall be provided:

(1) A fire pump controller power transfer switch complying with Sections 9.6and 10.8 and a fire pump controller shall be provided.

(2) The transfer switch overcurrent protection for both the normal and alternate sources shall comply with 9.2.3.4 or 9.2.3.4.1 or 9 . 2.3.4.2 .

(3) The transfer switch overcurrent protection shall be selected or set to indefinitely carry the locked rotor current of the fire pump motor where the alternate source is supplied by a second utility.

(4) An isolating switch ahead of the alternate source input terminals of the transfer switch shall meet the following requirements:

(a) The isolating switch shall be lockable in the on position.

(b) A placard shall be externally installed on the isolating switch stating “Fire Pump Isolating Switch,” with letters at least 1 in. (25 mm) in height.

(c) A placard shall be placed adjacent to the fire pump controller stating the location of the isolating switch and the location of the key (if the isolating switch is locked).

(d) The isolating switch shall be supervised to indicate when it is not closed, by one of the following methods:

i. Central station, proprietary, or remote station signal service

ii. Local signaling service that will cause the sounding of an audible signal at a constantly attended point

iii. Locking the isolating switch closed

iv. Sealing of isolating switches and approved weekly recorded inspections where isolating switches are located within fenced enclosures or in buildings under the control of the owner

(e) This supervision shall operate an audible and visible signal on the transfer switch and permit monitoring at a remote point whererequired.




This change reflects NEC CMP-13 Comment actions 13-37, Log #434 pertaining to (695.3(F)).

((This language isfrom current par. A.11.6.4))(5) No valves or other devices are added to the engine or its fuel supply and fuel return in any way. ((This language isfrom current par. A.11.6.4))

Commercial distillate fuel oils used in modern diesel engines are subject to various detrimental effects fromstorage. The origin of the crude oil, refinement processing techniques, time of year, and geographical consumptionlocation all influence the determination of fuel blend formulas. Sulfur, naturally occurring gums, waxes, soluble metallicsoaps, water, dirt, blends and temperature all contribute to the degradation of the fuel as it is handled and stored. Theseeffects begin at the time of fuel refinement and continue until consumption. Proper fuel storage is critical for engineoperation, efficiency, and longevity.Storage tanks should be kept water-free. Water contributes to steel tank corrosion and the development of

microbiological growth where fuel and water interface. This and the metals of the system provide elements that canreact with fuel to form certain gels or organic acids, resulting in clogging of filters and system corrosion.Scheduled fuel maintenance helps to reduce fuel degradation. Fuel maintenance filtration can remove contaminants

and water and maintain conditions to provide reliability and efficiency for standby fire pump engines. Fuel maintenanceand testing should begin the day of installation and first fill. In addition to an active fuel maintenance system a fuelstabilizer or other additives may be necessary to insure quality fuel for engine operation. Consult your active fuelmaintenance system supplier or fuel supplier for guidance regarding fuel additives and maintenance requirements forlong term storage.

Low fuel level. Fuel supply trouble. Signal at two-thirds tank capacity, or when active fuel maintenancesystem needs maintenance.

The characteristics of diesel fuel are changing and proper storage is becoming extremely important toinsure reliable operation of engines. Even when the proper fuel has been purchased and put into the fuel storage tanklong term reliability can not be assumed. For reasons as explained in the proposed annex text and governmentalmandated addition of various blends of bio-fuel, diesel fuel is requiring additional attention to insure reliable use in dieselengines for stand-by service.

Revise text to read as follows:Where environmental or fuel quality conditions result in degradation of the fuel while stored in the supply

tank from items such as water, micro-organisms and particulates, or destabilization, A listed active fuel maintenancesystem shall be installed to maintain fuel quality with all fuel storage tanks.

When required, The listed active fuel maintenance system shall be permanently connected to the fueltank as follows:

Report on Proposals – June 2015 NFPA 20This entire section reads as a reactive action. It states that “Where environmental or fuel quality

conditions result [emphasis added] in degradation . . .Reactive actions are not appropriate for an installation standard and should be assigned to NFPA 25. If the intent is forthe installer to somehow make a determination that the conditions exist from the onset, then how is that determined?The committee must either explain how to determine the conditions exist for degradation and then add the word could

before “result in degradation of the fuel” or require it for all fuel storage tanks. If the problem is as pervasive as thecommittee seems to believe, then it should be a requirement for all storage tanks.

This proposal 20-181 and comment 20-90 were returned to Committee at the A2012 AssociationTechnical Meeting and/or subsequent Standards Council Meeting. In accordance with 4.7.1(d) and 4.7.2(c) of theRegulations Governing Committee Projects, it is now being processed as a Proposal for this revision cycle.



11.6.4.2The tanks shall be designed and installed so that they can always be filled by means that will ensure removal the introduction of all water and foreign material is minimized .




The current text provides requirements for the design and installation that affect the process of filling the tank with fuel. The filling process will not remove water and foreign material from the tank, but should minimize the introduction of water and foreign material. Once water or foreign material has been introduced into the tank, removal is a another issue.









12.3.5.3.3 Unless approved by the Authority Having Jurisdiction, remote stopping or lockout of the fire pump shall not be allowed.




This has always been the intent of the committee based on past action, but is not stated anywhere in the standard.









12.4.1.4 Separate visible indicators and a common audible signal capable of being heard while the engine is running and operable in all positions of the main switch except the off position shall be provided to immediately indicate the following conditions:

(1)

(2) Battery charger failure. Each controller shall be provided with a separate visible indicator for battery charger failure and shall not require the audible signal for battery charger failure.

(3) Low air or hydraulic pressure. Where air or hydraulic starting is provided (see 11.2.7 and 11.2.7.4), each pressure tank shall provide to the controller separate visible indicators to indicate low pressure.

(4) System overpressure, for engines equipped with variable speed pressure limiting controls, to actuate at 115 percent of set pressure.

(5) ECM selector switch in alternate ECM position (for engines with ECM control only).

(6) Fuel injection malfunction (for engines with ECM only).

(7) Low fuel level. Signal at two-thirds tank capacity.

(8) Low air pressure (air-starting engine controllers only). The air supply container shall be provided with a separate visible indicator to indicate low air pressure.

(9) Low engine temperature.

(10) Supervisory signal for interstitial space liquid intrusion.(11) High cooling water temperature.

See uploaded file.




* Battery failure or missing battery. Each controller shall be provided with a separate visible indicator for each battery. The battery failure signal shall initiate at no lower than two-thirds of battery nominal voltage rating (8.0 V dc on a 12 V dc system). Sensing shall be delayed to prevent nuisance signals.

The recent recall of Transducers clearly identifies a problem for failure that can be monitered by current technology. While the recall addressed the immediate problem, there is a likelihood of similar issues occurring in future problems. Mercoid switches do not have a mechanism outside of actual testing to identify failures, Transducers communicate continuously with the controller and can and should be monitored for abnormal conditions that may occur outside of testing.

Special consideration needs to be given to fire pump installations installed belowgrade. Light, heat, drainage, and ventilation are several of the variables that need to be addressed. The vertical elevation of both the fire pump and the controller should be coordinated to ensure that both will not be flooded. Some locations or installations might not require a pump house. Where a pump room or pump house is required, it should be of ample size and located to permit short and properly arranged piping. The suction piping should receive first consideration. The pump house should preferably be a detached building of noncombustible construction. A one-story pump room with a combustible roof, either detached or well cut off from an adjoining one-story building, is acceptable if sprinklered. Where a detached building is not feasible, the pump room should be located and constructed so as to protect the pump unit and controls from falling floors or machinery and from fire that could drive away the pump operator or damage the pump unit or controls. Access to the pump room should be provided from outside the building. Where the use of brick or reinforced concrete is not feasible, metal lath and plaster is recommended for the construction of the pump room. The pump room or pump house should not be used for storage purposes. Vertical shaftturbine–type pumps might necessitate a removable panel in the pump house roof to permit the pump to be removed for inspection or repair. Proper clearances to equipment should be provided as recommended by the manufacturer's drawings.

Public Input No. 60-NFPA 20-2013 [ Section No. A.9.3.2 ]

A.9.3.2A reliable power source possesses the following characteristics:

(1) The source power plant has not experienced any shutdowns longer than 4 continuous hours in the year prior to plan submittal. NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems , requires special undertakings (i.e., fire watches) when a water-based fire protection system is taken out of service for longer than 4 than 10 hours. If the normal source power plant has been intentionally shut down for longer than 4 hours in the past, it is reasonable to require a backup source of power.

(2) Power outages have not routinely been experienced in the area of the protected facility caused by failures in generation or transmission. The standard is not intended to require that the normal source of power be infallible to deem the power reliable. NFPA 20 does not intend to require a back-up source of power for every installation using an electric motor–driven fire pump. Note that should the normal source of power fail in a rare event, the impairment procedures of NFPA 25 could be followed to mitigate the fire risk. If a fire does occur during the power loss, the fire protection system could be supplied through the fire department connection.

(3) The normal source of power is not supplied by overhead conductors outside the protected facility. Fire departments responding to an incident at the protected facility will not operate aerial apparatus near live overhead power lines, without exception. A backup source of power is required in case this scenario occurs and the normal source of power must be shut off. Additionally, many utility providers will remove power to the protected facility by physically cutting the overhead conductors. If the normal source of power is provided by overhead conductors, which will not be identified, the utility provider could mistakenly cut the overhead conductor supplying the fire pump.

(4) Only the disconnect switches and overcurrent protection devices permitted by 9.2.3 are installed in the normal source of power. Power disconnection and activated overcurrent protection should only occur in the fire pump controller. The provisions of 9.2.2 for the disconnect switch and overcurrent protection essentially require disconnection and overcurrent protection to occur in the fire pump controller. If unanticipated disconnect switches or overcurrent protection devices areinstalled in the normal source of power that do not meet the requirements of 9.2.2 , the normal source of power must be considered not reliable and a back-up source of power is necessary.

Typical methods of routing power from the source to the motor are shown in Figure A.9.2 . Other configurations are also acceptable. The determination of the reliability of a service is left up to the discretion of the authority havingjurisdiction.




The 2011 Edition of NFPA 25 revised more than 4 hours to more than 10 hours. While I am not sure the Annex note really makes sense as it would appear, at least it would be technically correct. The Committee may want to further revise the Annex note since the duration in NFPA 25 is not consistent with the 4 hour time period in NFPA 20.

A transducer that drifts downwardly will automatically cause the fire pump to start when it drifts below the start set point.A.12.7.2.1.2.1 When the solenoid valve drain opens, the restricting orifice in the pressure sensing line will keep the pressure at the transducer near zero while the solenoid valve is open. This is the time when the transducer can be verified to be less than 10 psi.













TITLE OF NEW CONTENT12.7.2.1.8.1 When one of the conditions monitered in 10.5.2.1.6 occurs, the controller shall either activate a visual and silenceable audible alarm and activate contacts for a remote alarm, or start the pump.A12.7.2.1.8: The purpose of monitoring pressure reading from a pressure transducer is to detect and correct a transducer that is operating outside of the expected pressure range.A.12.7.2.1.8(1) . For an electronic pressure sensor on the fire pump discharge, the preset high pressure should be set approximately 10 psi above the maximum anticipated churn discharge pressure.A.12.7.2.1.8(2) For an electronic pressure sensor on the fire pump discharge, the preset automatic start low should be set approximately 5 psi above the lowest pressure observed in the pressure sensing line during an automatic pump start.A.12.7.2.1.8(3) For an electronic pressure sensor on the fire pump suction, the preset low pressure should be set approximately 5 psi below above the minimum pump suction pressure. For an electronic pressure sensor on the fire pump discharge the preset low pressure value should be set approximately 10 psi below the pump discharge pressure at 150% of rated flow.

Appendix Material for12.7.2.1.7











A.14.2.6.4The test procedure is as follows:

(1) Make a visual check of the unit. If hose and nozzles are used, see that they are securely tied down. See that the hose valves are closed. If a test meter is used, the valve on the discharge side of the meter should be closed.

(2) Start the pump.

(3) Partially open one or two hose valves, or slightly open the meter discharge valve.

(4) Check the general operation of the unit. Watch for vibration, leaks (oil or water), unusual noises, and general operation. Adjust packing glands.

(5) Measure water discharge. The steps to do so are as follows:

(a) Where a test valve header is used, regulate the discharge by means of the hose valves and a selection of the nozzle tips. It will be noticed that the play pipe has a removable tip. This tip has a 1 1 ⁄ 8 in. (28.6 mm) nozzle, and when the tip is removed, the play pipe has a 1 3 ⁄ 4 in. (44.4 mm) nozzle. Hose valves should be shut off before removing or putting on the 1 1 ⁄ 8 in. (28.6 mm) tip.

(b) Where a test meter is used, regulate the discharge valve to achieve various flow readings.

(c) Important test points are at 150 percent rated capacity, rated capacity, and shutoff. Intermediate points can be taken if desired to help develop the performance curve.

(6) Record the following data at each test point (see FigureA.14.2.6.4 ):

(a) Pump rpm

(b) Suction pressure

(c) Discharge pressure

(d) Number and size of hose nozzles, pitot pressure for each nozzle, and total gpm (L/min); for test meter, simply a record of gpm (L/min)

(e) Amperes (each phase)

(f) Volts (phase to phase)

(7) Calculation of test results is as follows:

(a) Rated Speed. Determine that pump is operating at rated rpm.



(b) Capacity. For hose valve header, using a fire stream table, determine the gpm (L/min) for each nozzle at each pitot reading. For example, 16 psi (1.1 bar) pitot pressure with 1 3 ⁄ 4 in. (44.4 mm) nozzle indicates 364 gpm (1378 L/min). Add the gpm for each hose line to determine total volume. For test meter, the total gpm (L/min) is read directly.

(c) Total Head for Horizontal Pump . Total head is the sum of the following:

i. Pressure measured by the discharge gauge at pump discharge flange

ii. Velocity head difference, pump discharge, and pump suction

velocity head= h v = V 2 /2g

iii. Gauge elevation corrections to pump centerline (plus or minus)

iv. Pressure measured by suction gauge at pump suction flange —negative value when pressure is above zero

(a) Total Head for Vertical Pump. Total head is the sum of the following:

(8) Pressure measured by the discharge gauge at pump discharge flange

(9) Velocity head at the discharge

(10) Distance to the supply water level

(11) Discharge gauge elevation correction to centerline of discharge

(12) Electrical Input. Voltage and amperes are read directly from the volt/ammeter. This reading is compared to the motor nameplate full-load amperes. The only general calculation is to determine the maximum amperes allowed due to the motor service factor. In the case of 1.15 service factor, the maximum amperes areapproximately 1.15 times motor amperes, because changes in power factor and efficiency are not considered. If the maximum amperes recorded on the test do not exceed this figure, the motor and pump will be judged satisfactory. It is most important to measure voltage and amperes accurately on each phase should the maximum amperes logged on the test exceed the calculated maximum amperes. This measurement is important because a poor power supply with low voltage will cause a high ampere reading. This condition can be corrected only by improvement in the power supply. There is nothing that can be done to the motor or the pump.



(13) Correction to Rated Speed. For purposes of plotting, the capacity, head, and power should be corrected from the test values at test speed to the rated speed of the pump. The corrections are made as follows.

Capacity:

where:

Q 1 = capacity at test speed in gpm (L/min)Q 2 = capacity at rated speed in gpm (L/min)N 1 = test speed in rpmN 2 = rated speed in rpm

Head:

where:

H 1 = head at test speed in ft (m)H 2 = head at rated speed in ft (m)

Horsepower:

where:

hp 1 = kW (horsepower) at test speedhp 2 = kW (horsepower) at rated speed

(14) Conclusion . The final step in the test calculation is generally a plot of test points. A head-capacity curve is plotted, and an ampere-capacity curve is plotted. A study of these curves will show the performance picture of the pump as it was tested.
