Page 9: Introduction
1. INTRODUCTION 1.1. General DuraQuench is an FM Approved single fluid water mist system for the protection of non‐storage occupancies, Hazard Category 1 (HC‐1). The primary components of the DuraQuench Wet Pipe system consists of a fire pump skid, patented OH‐VSO fine water spray nozzles, ancillary FM Approved components (i.e., control valves, backflow preventers, isolation valves, etc.), and a reliable water source (i.e., public mains, gravity tanks or other suitable water sources). These components are connected together as a system to deliver water mist to the protected enclosure to control, suppress, or extinguish fires. With a minimum operating pressure of 116 psi (8 bar) and a maximum operating pressure of 232 psi (16 bar) at the system nozzles, the system is classified by NFPA 750, Standard on Water Mist Fire Protection Systems as an intermediate pressure system. 1.2. System Description When configured as a Wet Pipe System, DuraQuench is a fixed protection system in which the pipe system is filled with pressurized water up to the nozzles during normal standby operation. A system check valve serves to maintain system pressures in the piping network. Wet pipe systems may be installed in any structure that is reliably maintained above 40°F (4°C). Closed, heat‐sensitive, automatic nozzles located and spaced throughout the protected areas are used to detect a fire. Optional smoke detectors can be installed in the protected area to provide advanced notification of a fire event. Upon activation of a nozzle due to heat from the fire, water will begin to flow immediately from the open nozzle and will cause a drop in system pressure. Depending upon the system configuration, either the flow of water or the pressure ... -
Page 10: Figure 1: Wet Pipe System
Both the WAC valve’s water flow sensor and the water flow switch have an adjustable time delay that inhibits the initiation of a water flow signal in order to reduce the possibility of false alarms and false activation of the pump that can be caused by pressure drops or fluctuations in the water supply.

Page 12: When Should A Pressure Maintenance Pump Be Used
Section 3.11 for water supply requirements) be relatively free from pressure fluctuations and the pipe network be designed to provide the water flow required to trip the flow switches used for pump activation and alarm notification, based on the activation of a single OH‐VSO nozzle. Hydraulic calculations must be performed on the pipe network prior to installation to confirm that the water supply is capable of providing the pressure required to obtain the water flows required for pump activation. In addition, the installed system must be functionally tested using the remote test valve and an OH‐VSO orifice test fitting to verify pump activation based on the activation of a single nozzle. If the water supply is NOT capable of providing sufficient flow and pressure for pump activation, a pressure maintenance pump system, as detailed in Section 1.2.2, must be installed. Wet Pipe System with a Pressure Maintenance Pump NOTE ‐ DuraQuench systems configured with a pressure maintenance pump are not within the scope of the system’s FM Approval. This system configuration (see Figures 3 and 4) incorporates a pressure maintenance (jockey) pump into the DuraQuench system. The jockey pump can be mounted directly onto the pump skid or field installed off the pump skid. The jockey pump installation will include a separate jockey pump controller and its own independent pressure sensing line connection. The purpose of the jockey pump is two‐fold. The first purpose is to maintain a higher pressure on the system side of the Fike Wet Alarm Check Valve (WAC) than the standard water supply can reach. The higher pressure holds the clapper of the WAC valve and Water Flow switch closed even when the water supply pressure fluctuates. This eliminates false ... -

Page 15: Water Mist Principle
As the water spray is converted to steam, it expands approximately 1,700 times forcing oxygen away from the vicinity of the droplet. This results in dilution of the air (oxygen) supply within the protected enclosure. If the amount of oxygen necessary to support combustion is reduced below a critical level (14% – 13%), the energy output of the oxidation process fails to become close to the energy input the fire requires to sustain the chemical fire process which will cause the fire to burn inefficiently making it easier to extinguish. Blocking of Radiant Heat As water mist is released into the protected enclosure, the fine water droplets block the radiant heat generated by the fire from getting to unignited fuel surfaces and reduces the radiant heat flux between the flame and the fuel surface. 1.4. Water Mist Versus Traditional Sprinkler System Water mist has several advantages over conventional sprinkler systems. One of the key benefits of the DuraQuench system is that it typically uses 75% less water than a sprinkler system. With a water mist system, the majority of the water droplets are evaporated by the heat and hot gases generated by the fire resulting in much less water damage to the protected property and a dramatic reduction in downtime for cleanup. In light hazard applications, the reduced downtime means that the facility will be able to resume normal operations very quickly after a fire event. In contrast, traditional sprinkler systems spread large water droplets over the protected enclosure to absorb heat and cool the room. Due to the large size and relatively small surface area of sprinkler water droplets, they will not absorb enough energy to evaporate and quickly fall to the floor as water. This results in limited cooling of the fire and greater water damage to the protected property causing a large increase in facility downtime due to the fire event. P/N 06‐791‐4 (Rev. 4) ... -

2. EQUIPMENT The DuraQuench wet pipe water mist system consists of a number of OH‐VSO nozzles and wet pipe alarm check valve connected by a piping network to a continuous pressure pump skid unit, which is connected to a suitable water source (i.e., public mains, gravity tanks, reservoirs, etc.). This section provides a description of the components that can be used to construct the DuraQuench wet pipe water mist system. 2.1. Sourcing System Components The DuraQuench pump skid unit and the OH‐VSO nozzles are the only two components that must be purchased from Fike in order to maintain FM Approval. The remaining system components including wet alarm check valve, detection and control panel, control valves, piping, switches, etc. can be sourced from other suppliers. The operating pressure requirement of the DuraQuench system allows the use of traditional FM Approved sprinkler components and wet pipe system valves. Components selected for use on the DuraQuench system shall be FM Approved for use in wet pipe sprinkler systems. All system components should be a part of an FM Approval follow up service. It is very important to verify that the components are suitable for use in the DuraQuench system regarding: Component materials ... - Page 18 Ordering 02‐14870‐A‐B‐C‐D‐E A (Material): 1 = Brass; 2 = SST B (Threads): 1 = ½ NPT; 2 = ½ BSP C (Cover Plate): 1 = Chrome Plated; 2 = White (RAL 9010) D (Temperature): 1 = 57°C (135°F)*; 2 = 68°C (154°F); 3 = 79°C (174°F); 4 = 93°C (199°F) E (Drop Pipe Length)** FM Approved release temperature.

- Page 24 Pump Skid Ordering Format The DuraQuench pump skid can be ordered with different pump controller and pump combinations. When ordering the pump skid, it is extremely important to verify the voltage and frequency (50/60 Hz) of the power feed supplying the pump skid before selecting the appropriate pump skid part number. The voltage and frequency of the pump controller and the pump selected must be compatible with the available power supply. The fire pump controller is available in the following configurations: 1) Standard single source pump controller provides across‐the‐line full voltage starting for the three phase motor driven pump. No transfer switch included. 2) Dual source pump controller incorporates a transfer switch directly into the standard pump controller enclosure. The transfer switch provides for automatic transferring of the pump load from one power source to another (self‐ acting). 3) Variable speed fire pump controller provides a variable frequency drive (VFD) built into the standard pump ...

Page 29: Wet Alarm Check Valve (Wac)
2.6. Wet Alarm Check Valve (WAC) The Wet Alarm Check (WAC) valve is a clapper and wafer style check alarm valve designed to be installed in wet pipe water mist systems downstream from the system pump where the valve is fitted between two flanges. The valve is capable of detecting the small water flows which are common in the DuraQuench system. The valve has built in inlet and outlet pressure gauges, a drain valve, an inductive alarm sensor and Anti‐False Alarm (AFA) unit. The valve’s inductive alarm sensor provides an electrical means to detect water flow through the valve without direct contact with moving parts. The AFA is connected to the WAC valve and monitors the inductive alarm sensor for indication of water flow. The AFA provides a factory set time delay of 8 – 10 seconds, which reduces the risk of false alarms coming from pressure shocks in the pipe system. The unit provides a relay contact that provides a means to send a signal to the alarm panel for activation of a water flow alarm bell. The unit ... -

2.7. Check Valve The ARGCO Check Valve is used in a DuraQuench system to prevent the reversal of water flow. In the fully‐open position the clapper is held tightly against the valve body, out of the flow stream, to provide maximum flow area and prevention of clapper flutter. The clapper design produces quick, non‐slam closure before flow reversal can occur while meeting FM requirements for anti‐water hammer valve rating.

Page 45: Piping Network
ASTM B‐75/B‐88 Welded, Brazed, Flared, Compression CAUTION To prevent clogging of the system nozzles, it is prohibited to use components with black iron, hot galvanized or electro galvanized pipe and system components used in traditional sprinkler systems, because of corrosion and risk of loose zinc flakes. When using CPVC pipe on a wet pipe system, the pipe and fittings must be approved per FM 1635, Approval Standard for Plastic Pipe and Fittings for Automatic Sprinkler Systems. CPVC pipe is not permitted to be used in seismically active areas in accordance with FM Global Loss Prevention Data Sheet 2‐8. CPVC pipe must be shielded from the fire area by a non‐removable barrier having a fire rating equal to or greater than 1 hour. A pressure reducing valve (See Section 2.14) MUST be installed in the system pipe network just prior to transitioning to CPVC. The PRV is required to regulate the inlet pressure supplied to the CPVC distribution piping to a maximum service pressure of 175 psi (12 bar) in order to prevent over‐pressurization. Refer to FM Datasheet 3‐11 for the use of the PRV. NOTE: From this point forward, where the word pipe is used it shall imply tubing as well. Fittings Fittings shall have a minimum rated system design working pressure equal to or greater than the maximum operating pressure of the water mist system at 130°F (54°C) and shall have corrosion resistance at least equivalent to wrought copper fittings conforming to ASME/ANSI B16.22, Wrought Copper and Alloy Solder Joint Pressure Fittings. Galvanic Corrosion To avoid galvanic corrosion from occurring in the water mist system, all component materials incorporated into the system shall be compatible so no galvanic reaction can take place, or as a minimum be electrically insulated from the pipe materials to the satisfaction of FM Approval and the authorities having jurisdiction.

Applied using system components of good quality and reliable products, which are accepted and approved by FM Global and the AHJ, and that are suitable for their particular use in the system. See Section 2.1. 4. Designed to fully match the location and application to be fire protected. 5. Hydraulically designed from water supply to water mist nozzles. The hydraulic design shall ensure that minimum requirements of water flow and water pressure on all nozzles meets the design criteria and is ... -
Page 47: Electrical Clearances
All water mist system components (e.g., nozzles, piping, detectors, etc.) shall be located to maintain minimum clearances from unenclosed and uninsulated energized electrical components in accordance with NFPA 70, National Electrical Code. Refer to NFPA 750, Standard on Water Mist Fire Protection Systems for further information and clearance data. 3.3.

Selection of the type of detector to use for releasing of the system shall be based on a thorough review of the project requirements. ... -
Page 49: Protected Enclosure
Planning shall include considerations for equipment access, heating, lighting, emergency lighting and ventilation. The pump room shall provide protection for both the pump operator and pumping equipment during a fire event. Consideration should be given to locating the pump room at grade level, with direct access to the exterior of the building, to provide quick and easy egress for the pump operator and access to the pumping equipment for fire department personnel. Where the pump room cannot be located on grade with direct access from the outside of the building, a fire rated and protected space must be provided. The space must be accessible through an enclosed passageway from an exterior exit from an enclosed stairway. 3.11. Water Supply The water supply source for the DuraQuench system shall meet the requirements of NFPA 750, NFPA 13, and FM Global, with exceptions to the water density, water flows, and pipe system materials described in this manual. The water supply source shall comply with the overall design of water supply systems for wet pipe sprinkler systems for fire protection of similar locations. Water Supply Source The water supply shall be supplied by one of the following sources: 1. A connection to a reliable waterworks system (public service main) capable of providing the necessary water flow, water pressure, and quantity of water needed for the operation of the water mist system. Adequacy and dependability of the water source shall be fully determined from a water flow test or other approved method ... -
Page 50: Water Quality
4. No additives allowed for an FM approved system. Water Supply Capacity The water supply, when operating under reasonable, anticipated, worst‐case conditions must be capable supplying 150% of the pump’s rated flow for the required duration of the water demand at the minimum inlet pressure (NPSHR) required by the pump in accordance with the requirements of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection and FM Property Loss Prevention Data Sheet 3‐7, Fire Protection Pumps. The water supply must also be capable of maintaining a positive pump suction pressure at the pump inlet while providing the maximum fire protection system demand at residual pressure. Maintaining a positive suction pressure at the pump inlet helps to reduce the potential for cavitation within the pump, which can reduce the efficiency or even cause damage to the fire pump. If the water supply cannot provide 150% of the rated flow of the pump, but can provide the maximum flow demand of the system, it shall be deemed to be adequate; however, a sign shall be placed in the pump room indicating the minimum suction pressure that the fire pump is allowed to be tested at and also indicating the required flow rate. The minimum NPSHR for the pumps used on the DuraQuench system can be obtained from the pump curves provided in Annex C. The minimum NPSHR shall be selected at the highest flow the pump will be delivering plus a safety margin of 2.0 feet (0.61m). CAUTION Do not exceed the manufacturer’s set limits for the pump with regards to maximum inlet pressure and maximum operating pressure. See Motor and Pump Specifications on Page 19. The water supply capacity shall meet the hydraulically calculated design flow requirements and the minimum system flow duration requirements of the actual system as listed in the following table. Applicable Standard Minimum System Discharge Duration 30 minutes to the hydraulically most remote nine automatic nozzles or all automatic NFPA 750 (Light nozzles within a 1,500 ft (140 m... -
Page 51: Design Process
3.12. Design Process The basic design principals of the DuraQuench wet pipe water mist system are identical to that of traditional sprinkler wet pipe systems. The following process shall be used to properly design a DuraQuench wet pipe water mist system for protection of non‐storage occupancies. Determine Nozzle Layout The OH‐VSO nozzles shall not be installed in locations containing materials which may produce violent reactions or significantly hazardous materials when reacting with water and should be installed in locations where the nozzle is not likely to sustain physical damage. The nozzles shall be installed within the protected enclosure in a homogenous grid covering the whole area of the enclosure. Spacing of the nozzles shall be in accordance with the requirements listed below. Maximum ceiling height 16.42 ft. (5 m) Minimum ceiling height 6.6 ft. (2 m) Maximum nozzle spacing 14.75 ft. x 14.75 ft. (4.5 m x 4.5 m) Minimum nozzle spacing 7.42 ft. x 7.42 ft. (2.25 m x 2.25 m) Maximum nozzle distance to wall 7.33 ft. (2.25 m) Minimum nozzle distance to wall 3.17 ft. (1.125 m) ... -
Page 52: Nozzle Obstructions
Nozzle Obstructions Care should be given when installing the OH‐VSO nozzles adjacent to major obstructions. A major obstruction is defined shall be defined as an object which obstructs a significant portion of the spray from the OH‐VSO nozzle. If the area to be protected houses one or more major obstructions (i.e., beams, walkways, ductwork, etc.) additional nozzles shall be installed adjacent to the obstructions. If it is not possible to protect the area underneath or next to the obstruction, depending upon the elevation of the obstruction, additional OH‐VSO nozzles shall be installed beneath the obstruction in order to provide a homogenous distribution of the water mist in the enclosure. For more on obstructions, see Annex C. NOTE ‐ Systems with nozzles installed as described in this section are not part of the DuraQuench system FM Approval. Determine Nozzle Flow Rate Use the following formula to calculate the flow rate from each OH‐VSO nozzle using the given K‐factor for the nozzle (1.16 (gal/min/√psi or 16.7 (l/min/√bar). The K‐factor is a constant that gives the ratio between the flow rate and the pressure at the nozzle. System pressure (P) at the nozzle will vary between 116 to 232 psi (8 – 16 bar). The most favorable condition shall be considered. Q = K * P Where: Q = Flow from the nozzle (gal/min or l/min.) K = Nozzle K factor (gal/min/psi or l/min/bar) P = Pressure at the nozzle (psi or bar) Determine System Flow Rate The system shall be capable of supplying water to the hydraulically most remote nine nozzles or all nozzles within a 1,500 ft (140 m ) demand area, whichever is greater. If the demand area is less than 1,500 ft (140 m ) in area, the system shall be capable of supplying water to all nozzles in the protected area. To calculate the total flow rate for the system, multiply the calculated nozzle flow rate by the total number of nozzles serving the remote demand area. = Q * N Where: = Total flow for the demand area (gal/min or l/min.)

Close the discharge isolating valve on the pump skid to prevent water from flowing into the piping network. 2. Close the water supply isolating valve on the pump skid to prevent water from flowing into the pump skid. 3. Open the priming plug on the pump head. See Figure 60. LOOSEN CENTER PLUG TO VENT PUMP Figure 59: Fire Pump Vent Plug 4. Gradually open the water supply isolating valve on the pump skid until a steady stream of airless water runs out of the priming hole. 5. Close the plug and tighten securely. 6. Completely open the water supply isolating valve on the pump skid. The discharge isolating valve should remain closed until testing of the pump is complete. 7. Pump is now ready for functional testing. P/N 06‐791‐4 (Rev. 4) Page 73 704 SW 10 Street, P.O. Box 610, Blue Springs, Missouri 64013‐0610 U.S.A. ● Phone: (816) 229‐3405 ● www.fike.com ... -

10. Re‐close the controller cabinet door then close the IS and CB to re‐energize the controller. 11. Jog (bump) the motor again to verify correct direction of rotation (counter‐clockwise). 12. Once the correct direction of rotation has been visually verified, open the CB and the IS to remove power from the controller. 13. Replace the coupling guard on the fire pump; then re‐apply power to the controller. Do not attempt to reinstall the coupling guard while power is applied to the controller. 14. Check that the display is powered up with no Alarms present. CAUTION Motors should not be run unloaded or uncoupled from the pump at any time; damage to the motor bearings will occur. Do not start the pump before priming or venting the pump. Never let the pump run dry. Page 74 P/N 06‐791‐4 (Rev. 4) 704 SW 10 Street, P.O.
