3 NFPA standards Fire DNF, Fire HSEF Introduction to the NFPA The National Fire Protection Association (NFPA) is an international, non-rofit organisation of fire safety rofessionals. The NFPA headquarters is located in the USA. The organisation creates and maintains minimum accetable standards and requirements for fire revention and suression activities, training, equiment and other life-safety codes and standards. NFPA standards are tyically revised every three years in order to kee guidelines udated and to revent the loss of life and roerty due to fire. See the NFPA homeage: NFPA DNF and HSEF bare shaft ums comly with the NFPA Standard for the Installation of Stationary Fire Pums for Fire Protection. The standard covers systems for commercial, industrial and rivate buildings. The ums have been tested and certified by FM Global to comly with the requirements of the NFPA. (FM is short for Factory Mutual.) Comliance with the requirements is indicated by the FM mark affixed to the ums. See fig. 1. Standards aroval rocess Grundfos tests the ums and fills in the alication forms for each individual um size. We submit this documentation to the FM: Exected um erformance, including total head, ower requirement and efficiency versus flow characteristics. If different imeller diameters are used to obtain the rated head for the um to be examined, comlete details must be rovided concerning erformance secifications to be evaluated. Calculations to determine shaft size, casing bolt size and anti-friction bearing life. General assembly drawings, a comlete set of manufacturing drawings, materials lists and hysical roerty secifications, exected marking format, brochures, sales literature, secification sheets, installation, oerating and maintenance rocedures. When the alication forms have been acceted, the FM will attend the final test at the Grundfos remises. When the evaluation of the test results is ositive, the FM will issue a certificate of comliance of the um with the standards secified. When a um comonent is relaced after the certificate of comliance has been issued, reresentative samles of the um may need to be retested. FM TM APPROVED Fig. 1 FM and NFPA marks TM Other NFPA standards These standards are also of relevance to the roducts described in this data booklet: NFPA 13. Installation of srinkler systems NFPA 25.

5 NFPA standards Fire DNF, Fire HSEF System design A fire system tyically consists of three ums: one ressure um (jockey um) and two fire ums, one duty and the other acting as standby. Each of the fire ums is caable of achieving the required erformance. Systems with only one fire um with a redundant ower suly or more than two fire ums are, however, also seen. Oeration The jockey um maintains ressure in the system and comensates for any loss of ressure caused by leaks and thus revents the duty um from starting unnecessarily. The jockey um has two ressure levels: a low ressure level to start the jockey um a high ressure level to sto the jockey um. In case of further decrease of system ressure due to fire (i.e. srinkler oens), the duty um will start. In case this um fails to start or breaks down, the standby um will start. The duty and standby ums are not owered by the same source. This ensures that if one um fails, for examle due to fire damage, the other will oerate. The ums are controlled by ressure sensors. Although individually designed for the secific installation, each fire unit must comly with NFPA standards. Fire ums FM-aroved Grundfos end-suction and slit-case ums are designed for the distribution of water in automatic srinkler and standie systems. They are oerated in case of fire and during tests. Materials Imeller, wear rings, guide or diffusion vane rings, lantern rings, bottoms of stuffing boxes, interior nuts, linings of stuffing-box throats, glands, gland nuts and drain lugs are made of material aroved by the FM and UL. Performance requirements FM-aroved ums comly with requirements concerning these features: flow rate vs. ressure closed-valve ressure motor ower rating. Flow rate vs. ressure The aroval/listing of the um is based on a certain rated flow rate, indicated by the solid line in the curve charts. The um must be able to suly not less than 1 % of the rated flow rate (broken line) and still be able to rovide at least 65 % of the total rated ressure when oerating at a suction lift of at least 4.6 m (15 ft) referred to water surface. See fig. 3 and the examle below /311 % Q[USGPM] Fig. 3 Flow rate vs. ressure 1% Examle The um comlies with a flow requirement of 7 gm (1 m 3 /h). At this flow rate, the um delivers a ressure of 44 si (31 mh). To be FM-aroved or ULlisted, the um must comly with these requirements: Rated flow rate ( %): Maximum flow rate sulied by the um (1 %): Rated ressure ( %): Minimum ressure sulied by the um (65 %): % HSF 6-12 n nom = 14 min -1 65% ISO 96 Annex A 7 gm (1 m 3 /h) 1125 gm (256 m 3 /h) At 1 % of the total rated flow rate, the um delivers a ressure of 34 si (24 metres head). This means that the um comlies with the requirements. TM si (31 metres head) 34 si (24 metres head) 5

6 NFPA standards Fire DNF, Fire HSEF Closed-valve ressure The closed-valve ressure must be at least 101 % and not higher than 1 % of the total rated ressure. See fig. 4 and the examle below /311 Fig. 4 Closed-valve ressure Examle The curve shows a rated ressure of 44 si (31 mh). To be FM-aroved or UL-listed, the um must comly with these requirements: Rated ressure ( %): Minimum closed-valve ressure (101 %): Maximum closed-valve ressure (1 %): 1% HSF 6-12 n nom = 14 min -1 % ISO 96 Annex A Q[USGPM] The um has a closed-valve ressure of 53 si (37 metres head). This means that the um comlies with the requirements. Motor ower rating The maximum motor current under any condition of um load must not exceed the rated full-load current multilied by the service factor, if any. Service factors must be in accordance with NEMA Standard MG-1. To ensure that the motor is caable of oerating the um at any time, the NFPA demands that the manufacturer determines the maximum ower required at a certain duty range. The maximum ower occurs when there is no increase in ower with an increase in the flow rate. See fig. 5 and the examle below. TM si (31 metres head) 44 si (31 metres head) 61 si (43 metres head) Examle The maximum ower required for this um is 25 kw. If the motor service factor is 1, the minimum motor size required will be 25/1 = 25 kw. If the motor service factor is 1.15, the minimum motor size required will be 25/1.15 = 21.7 kw. Other system comonents Electric motors Grundfos electric fire systems are tyically equied with MMG-E motors (sourced HEM EFF2 motors) manufactured according to IEC 034. Other motor makes are available on request. Insulation class: F. Enclosure class: IP55. Note: NEMA motors are available on request. Jockey ums Grundfos CR ums are used as jockey ums, maintaining the ressure. Under normal conditions, the jockey um will be activated by the low-ressure switch as a result of small leakages, or if one or more srinklers are activated. The jockey um is not subject to any secific NFPA requirements. Control anel The control anel has the CE-mark. The control anel for the fire ums must comly with NFPA requirements. In addition, the cabinet must be listed by UL and ULC and aroved by the FM and CSA. The control anel is ainted with RAL 02 (red) and housed in a NEMA tye-2 dri-roof enclosure. The control anel is suitable for wall mounting or floor mounting. See Tye keys, age / Q[USGPM] Fig. 5 Motor ower rating TM

19 Construction Fire DNF, Fire HSEF Stuffing box The stuffing box is sealed with braided acking rings. The braided material ensures a long service life of acking rings and rotects the um shaft (sleeve). The acking rings are fitted symmetrically with arallel faces to revent tilting. The acking ring joints are alternately staggered to aid sealing. Removal of the uer casing allows for ease of insection and service of the stuffing box. Couling Electrically owered DNF and HSEF ums are available with two tyes of couling: standard sacer (Fire DNF only). Packing ring materials PTFE-imregnated fibre acking rings and EPDM O-rings in um housing. Barrier fluid DNF: internal barrier fluid (fig. 16). HSEF: external barrier fluid (fig. 17).

This saves realignment of um and motor after service. The slit-case construction of HSEF um enables removal and dismantling of the internal um arts, e.g. bearings, wear rings, imeller and acking rings, without disturbing the motor or iework. Imeller The closed imeller made of bronze has double-curved blades with smooth surfaces for high efficiency.

21 Oerating conditions Fire DNF, Fire HSEF Location The um set is designed for installation in a nonaggressive and non-exlosive atmoshere. The relative air humidity must not exceed 95 %. Ambient temerature and altitude The ambient temerature must not exceed + C (104 F). If the ambient temerature exceeds + C (104 F), or if the motor is installed more than 0 metres (32 ft) above sea level, the motor must not be fully loaded due to the low density and consequently low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher outut. See fig t [ C] m Fig. 24 Relationshi between motor outut () and ambient temerature/altitude TM Inlet ressure Maximum inlet ressure The inlet ressure is limited by the maximum oerating ressure of the um and the acking material. Minimum inlet ressure Refer to the latest National Fire Protection Association amhlet (NFPA ) for rules and excetions. 21

22 Installation Fire DNF, Fire HSEF Piing Make sure that the um housing is not stressed by the iework. Comly with the um's maximum forces and moments allowed. The suction and discharge ies must be of an adequate size, taking the um inlet ressure into account. Refer to the rules and regulations of NFPA. Install the ies so that air locks are avoided, esecially on the suction side of the um. See fig. 25. Alignment In a comlete um unit assembled and sulied from factory, the couling halves have been accurately aligned. Alignment is made by inserting shims under the um and motor mounting surfaces, as required. The um/motor alignment may be affected during transort. Always check the alignment after the um has been installed. If misalignment has occurred due to radial or angular shifting, realign by inserting/removing shims under the suorting feet of the um or the motor. Take care to align carefully as this will increase the working life of the couling, bearings and stuffing boxes. Note: Check the final alignment when the um has obtained its oerating temerature under normal oerating conditions. Fig. 25 Pie sections Fit isolating valves on either side of the um to avoid having to drain the system if the um needs to be cleaned or reaired. Make sure the ies are adequately suorted as close to the um as ossible, both on the suction and on the discharge side. The counter-flanges should lie true against the um flanges without being stressed; otherwise, the um will be damaged. TM TM Fig. 26 Examle of iing, Fire DNF 22

FM-aroved ressure range Examle: DNF -, 0 gm. Pressure range Rated ower Curve conditions Selection of ums The guidelines below aly to the erformance curves shown in the curve charts, ages to. Tolerances according to ISO 96, Annex A. The curves show um erformance with different imeller diameters at the rated seed. The curves aly to the uming of water at a temerature of + C (68 F) and a kinematic viscosity of 1 mm ² /s (1 cst). Calculation of total head The total um head consists of the height difference between the measuring oints + the differential head + the dynamic head. H = H + H + H total geo stat dyn H geo : H stat : Height difference between measuring oints. Differential head between the suction and the discharge side of the um. H dyn : Calculated values based on the velocity of the umed water on the suction and the discharge side of the um. Note: Selection of the um is based on the head given by the customer. Performance tests The requested duty oint of every um is tested according to ISO 96, Annex A. The curve of the erformance test is sulied with the um. If the customer requires either more oints on the curve to be checked or certain minimum erformances or certificates, individual measurements must be made. 29
