To determine the most hydraulicallydemanding location of a wet pilot line,when the choice between two or morelocations is not readily apparent, determinefor each location the elevationabove the F470 Valve and the equivalentlength of fittings plus horizontalpipe from the F470 Valve to the location.Then, using Graph B, determinethe minimum system supply pressurerequired for the elevation and equivalentlength of pipe at each location.Interpolate between the equivalentlength plots as necessary. The locationrequiring the highest system supplypressure is the most hydraulically demandinglocation for the wet pilot line.(Reference: In no case should the requiredsystem supply pressure exceedthe actual available minimum expectedsystem supply pressure.)Operation of a pilot sprinkler or openingof a manual control station resultsin a rapid pressure drop in the DiaphragmChamber of the F470 Valve,and the force differential appliedthrough the Clapper Latch which holdsthe Clapper down in the set position isreduced to below the valve trip point.NOTESWet Pilot Lines must be maintained ata minmum temperature of 40%/4”C.It is recommended that internally galvanizedpipe and cast iron fittings beused for wet pilot lines.Dry Pilot Actuation(Figure F-l, Items 1 through 35 plusItems Dl through D14)The Dry Pilot Actuation Trim providesfor installation of a detection systemconsisting of dry pilot sprinklers (heatdetectors) and manual control stationsinterconnected with minimum l/2 inch(15 mm) steel pipe. The pilot line,which is to be oressurized with air ornitrogen, is connected to the “Dry PilotDetection” connection shown in FiaureF. Provision must be made for a”l/2inch (15 mm) orifice, Inspector’s TestConnection at the most remote locationfrom the F470 Valve. Nominal installationdimensions for Dry Pilot ActuationTrim are shown in Figure E.The Dry Pilot Actuation Trim is providedwith a listed and approved ModelB-l Dry Pilot Actuator, which is describedin Technical Data SheetTDll7W. The Actuator is rated for useat a maximum pilot service pressure of50 psi (3,4 bar) and a maximum watersupply service pressure of 175 psi(12,l bar).Operation of a pilot sprinkler or openingof a manual control station, releasespneumatic pressure from thepilot line. In turn, the Dry Pilot Actuatoropens resulting in a rapid pressuredrop in the Diaphragm Chamber of theF470 Valve, and the force differentialapplied through the Clapper Latchwhich holds the Clapper down in theset position is reduced to below thevalve trip point.Dry pilot sprinklers are to be minimuml/2 inch (15 mm) orifice listed or approvedautomatic sprinklers. ManualControl Stations are to be either theModel Fl80 or F184 described in TechnicalData Sheet TDl21.Graph C shows the “minimum pilot lineservice pressure” as a function of thewater supply pressure. The pressurein the dry pilot actuation system mustbe automatically maintained using oneof the following maintenance devices,as appropriate.• Model F324 Air Maintenance Device(pressure reducing type),refer to Technical Data SheetTDlll.• Model F326 Air Maintenance Device(compressor control type),refer to Technical Data SheetTDl12.• Model F328 Nitrogen MaintenanceDevice (high pressure reducingtype), refer to TechnicalData Sheet TDl13.NOTESThe dewpoint of the pilot line airpressuremust be maintained below thelowest ambient temperature to whichthe dry pilot actuation system will beexposed. Accumulation of water in thepilot line connection to the Actuatorwill lower the air pressure at whichthe Actuator will open and possiblyprevent proper operation. Also, introductionof moisture into the pilot linesexposed to freezing temperatures cancreate an ice buildup which couldpreventproper operation of the ActuatorAn air dryer must be installed wherethe moisture content of the air supplyis not properly controlled at less thanthe required value. The desiccantdryer with mounting accessories describedin Technical Data SheetTD135 is suitable for use with a maximuminlet pressure of 150 psi (lo,3bar) and for drying system air downto a dewpoint of less than -2O”Fl-29°Cat a pressure of 45 psi (3,l bar) .It is recommended that an F328 NitrogenMaintenance Device be utilizedin dry pilot actuation system applicationswhere the dewpoint must bemaintained below -2O”Fl-29°C. SeeTechnical Data Sheet TD113.It is recommended that internallygalvanizedpipe and cast iron fittings beused for dry pilot lines.Supervision of the pressure in the drypilot actuation system and/or alarm-5-which separately indicates operationof the detection system is recommendedand may be required by theauthority having jurisdiction. A dualsetting low pressure alarm switch,such as the unit described in TechnicalData Sheet TD210, is suitable for theservice. The recommended pressuresettings are as follows:. Low pressure alarm setting atapproximately 6 psi (0,4 bar)below the minimum pilot lineservice pressure requirementshown in Graph C.. Fire alarm setting at approximately15 psi (1 ,O bar) belowthe minimum pilot line servicepressure requirement shownin Graph C.The Pressure Relief Valve (Ref. ItemD5 - Fig. F-l) is factory set to relieveat a pressure of approximately 45 psi(3,1 bar); however, it may be field adjustedto a lower pressure, if required.Electric Actuation Trim(Figure F-l, Items 1 through 35 plusItems El through E5)The Electric Actuation Trim is requiredfor electric operation of the F470 Valveby a detection system consisting ofelectrical devices such as heat sensitivethermostats, smoke detectors,and/or electric manual pull stations.Information on the various types of SolenoidValves that may be used withthis trim package is given in TechnicalData Sheet TDll9. A listed and approved,24VDC Solenoid Valve fornon-hazardous locations is suppliedas standard. Nominal installation dimensionsfor the Electric ActuationTrim are shown in Figure D.NOTEApproval by Factory Mutual is contingenton the use of an FM Approved24VDC Solenoid Valve. FM only approvessolenoid valves for use in nonhazardouslocations.The Electric Actuation Trim is only tobe used in conjunction with an electricdeluge valve releasing panel (automaticcontrol unit) that is listed or approved(as appropriate) for fire protectionsystem releasing service. Inaddition, the deluge valve releasingpanel is only to be operated by listedor approved (as approriate) fire detectors.Operation of an electrical device suchas a heat sensitive thermostat, smokedetector, or electrical manual controlstation signals the deluge valve releasingpanel to energize the SolenoidValve. In turn, the energized SolenoidValve opens resulting in a rapid pressuredrop in the Diaphragm Chamberof the F470 Valve, and the force differ-

ential applied through the ClapperLatch which holds the Clapper down inthe set position is reduced to below thevalve trip point.NOTEConsult with the Authority HavingJurisdiction regarding installationcriteria pertaining to electric actuationcircuitry.TOSYSTEMThe Model F470 Multimatic DelugeValve is a differential latch type valvewhich depends upon water pressure inthe Diaphragm Chamber (Ref. FigureC-l) to hold the Clapper closedagainst the water supply pressure. Thenominal trip ratio is 2.5 to 1, i.e., theF470 Valve operates (opens) when thepressure in the Diaphragm Chamber isreduced to approximately 40 percentof the water supply pressure.WATER- Set Position -Figure C-lTOSUPPLYSYSTEMWhen the F470 Valve is set for service,the Diaphragm Chamber is pressurizedthrough the trim connections fromthe inlet side of the system’s main controlvalve, for example an O.S.&Y. gatevalve or butterfly valve (Ref. FigureG-l, G-2, or G-3). Opening of an actuationdevice, for example the solenoidvalve in the Electric Actuation Trim(Ref. Fig. G-3), releases water fromthe Diaphragm Chamber faster than itcan be replenished through the l/8inch (3,2mm) Restriction in the DiaphragmChamber Supply Connection.This results in a rapid pressure drop inthe Diaphragm Chamber and the forcedifferential applied through the ClapperLatch to hold the Clapper down inthe set position is reduced to below thevalve trip point. The water supply pressurethen forces the Clapper open permittingwater to flow into the systempiping, as well as through the AlarmPort to actuate the system alarms (Ref.Figure C-2).ALARMPORTWATER‘SUPPLY- Open Position (Flowing)-Figure C-2TOSYSTEMIIUPzz’When the system main control valve isclosed to stop waterflow into the system,the Clapper will be preventedfrom resetting by the Clapper Latchuntil the Rest Knob is pushed inward(Ref. Figure C-3). Pushing the ResetKnob inward will temporarily repositionthe Clapper Latch away from the waterwayand allows the Clapper to dropinto the seated position.WATER‘SUPPLY- Open Position (No Flow)-Figure C-3FIGURE CMODEL F470 EXTERNAL RESETTING MULTIMATIC DELUGE VALVE- SET AND OPEN POSITIONS --6-

12. Unused pressure alam switch connectionsmust be plugged.13. The Pressure Relief Valve providedwith the Dry Pilot Actuation Trim isfactory set to relieve at a pressure ofapproximately 45 psi (3,1 bar),which can typically be used for amaximum normal dry pilot actuationsystem pressure of 40 psi (2,8 bar).The Pressure Relief Valve mav bereset; however, it must be be rksetto relieve at a pressure which is inaccordance with the requirements ofthe authority havng jurisdiction.To reset the Pressure Relief Valve,first loosen the jam nut and thenadjust the cap accordingly - clockwisefor a higher pressure setting orcounterclockwise for a lower pressuresetting. After verifying the desiredpressure setting, tighten thejam nut.14. Conduit and electrical connectionsare to be made in accordance withthe requirements of the authorityhaving jurisdiction and/or the NationalElectric Code.Steps 1 through 12 are to be performedwhen initially setting the ModelF470 Multimatic Deluge Valve; after anoperational test of the fire protectionsystem; or, after system operation dueto a fire.1. Close the Diaphragm ChamberSupplyControl Valve.2. Close the Main Control Valve, and ifthe system is equipped with Dry PilotActuation, close the Air Supply ControlValve (Ref. Figure F-l).3. Open the Main Drain Valve and allauxiliary drains in the system. Closethe auxiliary drain valves after waterceases to discharge. Leave the MainDrain Valve open.4. Depress the plunger of the AutomaticDrain Valve to verify that it isopen and that the F470 Valve iscompletely drained.5. Push the Reset Knob inward to allowthe Clapper to reseat.Under normal circumstances, the reseatingof the Clapper can be heard;however, during an annual operationtest procedure, for example, due tominimal flow through a partiallyopened main control valve, the Clappermay not latch open as shown inFigure C-3. In which case the reseat-ing sound of the Clapper will not beheard.Also under normal circumstances,water pressure in the riser will haveexerted sufficient force on the Diaphragmso as to have emptied mostof the water from the DiaphragmChamber which, in turn, will easethe pushing of the Reset Knob byeliminating the resistive force producedby a water filled DiaphragmChamber. Therefore, should waterremain in the Diaphragm Chamber,the Reset Plunger will need to bedepressed with added force to pushthe remaining water out of the DiaphragmChamber and through anopen actuation device (e.g., a DryPilot Actuator or Solenoid Valve).NOTEZf the Reset Knob can not be depressedsufficiently to allow theClapper to reseat, operate (open)the Manual Control Station andthen once again push the ResetKnob with sufficient force to pushthe water out of the DiaphragmChamber through the ManualControl Station drain.Clean the Strainer in the DiaphragmChamber Supply connection by removingthe clean-out plug andstrainer basket. The Strainer may beflushed out by momentarily openingthe Diaphragm Chamber SupplyControl Valve.Open the Alarm Control Valve (Fig.F-l), if it was closed to silence localalarms.It is recommended that the AlarmControl Valve be wire sealed in theopen position with a No. 16 twistedwire, the ends of which are securedby a lead seal. The wire seal shouldbe looped through the hole in thehandle and tightly twisted around thepipe nipple adjacent to the handle.Reset the actuation system.Manual Actuation - Push the operatinglever up; however, do not closethe hinged cover at this time.Wet Pilot Actuation - Replace operatedpilot sprinklers and/or reset themanual control stations.Dry Pilot Actuation - Replace operatedpilot sprinklers and/or reset themanual control stations. Re-establishdry pilot pneumatic pressure.Electric Actuation - Reset the electricdetection system in accordancewith the manufacturer’s instructionsto de-energize the solenoid valve.NOTEIn order to prevent the possibility-9-of a subsequent operation of anoverheated solder type pilotsprinkler, any solder type pilotsprinklers which were possibly exposedto a temperature greaterthan their maximum rated ambientmust be replaced.9. Open the Diaphragm Chamber SupplyControl Valve and allow time forfull pressure to build up in the DiaphragmChamber.10. Operate (open) the Manual ControlStation to venttrapped air from theDiaphragm Chamber. If necessary,first open the hinged cover, and thenfully pull down on the operatinglever. SLOWLY close the operatinglever, by pushing it up, after aeratedwater ceases to discharge from theManual Control Station drain tubing.Close the hinged cover and insert anew break rod in the small holethrough the top of the enclosingbox.If wet pilot actuation is being used,crack open the Inspector’s Test Connectionand any other vent valves, torelieve trapped air. After the dischargeof air has stopped, close thevent valves and the Inspector’s TestConnection.11. Inspect drain connections from theManual Control Station, SolenoidValve, Dry Pilot Actuator, and AlarmDevices, as applicable. Any leaksmust be corrected before proceedingto the next step.12. Slowly open the Main Control Valve.Close the Main Drain Valve as soonas water discharges from the drainconnection. Observe the AutomaticDrain Valve for leaks. If there areleaks, determine/correct the causeof the leakage problem. If there areno leaks, the F470 Valve is ready tobe placed in service and the MainControl Vave must then be fullyopened.NOTEAfter setting a fire protection system,notify the proper authorities and advisethose responsible for monitoringproprietary and /or central stationalarms.
