GeneralDescriptionThe Model DV-5 Double Interlock Pre-action System with Electric/PneumaticActuation (Fig. 1) is designed for usein applications, such as refrigeratedareas, requiring the maximum degreeof protection against inadvertent flood-ing of the sprinkler system piping.

The Model DV-5 Double Interlock Pre-action System with Electric/PneumaticActuation utilizes a Model DV-5 DelugeValve and a Riser Check Valve. TheRiser Check Valve (that does not re-quire the use of priming water) isolatesthe Deluge Valve from the system airpressure. The releasing trim for theDeluge Valve utilizes a Solenoid Valveand a Dry Pilot Actuator in a seriesconfiguration. The system air pressureholds the Dry Plot Actuator closed,whereas the Solenoid Valve remainsclosed until it is electrically energizedby a Deluge Valve Releasing Panel(automatic control unit). The Releas-ing Panel is operated by either a firedetection device or manual electricpull station.

In order for the Double Interlock Pre-action System to automatically actu-ate, two independent events must oc-cur. The deluge valve releasing panelmust operate and open the SolenoidValve upon automatic operation of theelectric fire detection initiating circuitor manual operation of the electric-manual pull initiating circuit, and thesprinkler system piping must lose airpressure due to operation of one ormore sprinklers.

The Double Interlock Preaction Sys-tem will automatically actuate onlywhen both the Dry Pilot Actuator andthe Solenoid Valve are open at thesame time. Accidental opening of justthe Dry Pilot Actuator (for example: alift truck accidentally dislodges a sprin-kler), or just energizing the SolenoidValve (for example: an accidental op-

eration of an electric pull station), willonly cause an alarm, and will not actu-ate the system or flood the sprinklersystem piping.

The Model DV-5 Deluge Valve (de-scribed in Technical Data SheetTFP1305) is a diaphragm style valvethat depends upon water pressure inthe Diaphragm Chamber to hold theDiaphragm closed against the watersupply pressure. When the DV-5 Valveis set for service, the DiaphragmChamber is pressurized through thetrim connections from the inlet side ofthe system’s main control valve, for

example an O.S.&Y. gate valve or but-terfly valve (Fig. 1).

Operation of the Solenoid Valve andDry Pilot Actuator at the same timereleases water from the DiaphragmChamber faster than it can be replen-ished through the 1/8 inch (3,2 mm)Priming Supply Restriction (Item 7 -Fig. 2A) in the diaphragm supply con-nections. This results in a rapid pres-sure drop in the Diaphragm Chamberbelow the valve trip point. The watersupply pressure then forces the Dia-phragm open permitting water to flow

into the system piping, as well asthrough the Alarm Port to actuate thesystem alarms.

As water flows into the system, theModel FSV-1 Fail-Safe Valve (Item 5 -Fig. 2A, also described in TechnicalData Sheet TFP1386) becomes pres-surized and upon operation constantlyvents the DV-5 Diaphragm Chamberso as to maintain the DV-5 Valve in theopen (operated) position until the sys-tem is reset.

WARNINGThe Model DV-5 Double Interlock Pre-action System with Electric/PneumaticActuation described herein must beinstalled and maintained in compli-ance with this document, as well aswith the applicable standards of theNational Fire Protection Association,in addition to the standards of anyother authorities having jurisdiction.Failure to do so may impair the per-formance of the related devices.

The owner is responsible for maintain-ing their fire protection system and de-vices in proper operating condition.The installing contractor or manufac-turer should be contacted with anyquestions.

NOTE1-1/2 inch (DN40) risers utilize a 2 inch(DN50) Riser Check Valve in combina-tion with the 1-1/2 inch (DN40) ModelDV-5 Deluge Valve.

Valve TrimThe Double Interlock Preaction Sys-tem with Electric/Pneumatic ActuationTrim (Fig. 2A/2B) forms a part of thelaboratory listings and approvals. Thetrim is necessary for proper operationof the DV-5 Valve.

Each package of trim includes the fol-lowing items:

• Water Supply Pressure Gauge• Diaphragm Chamber

Pressure Gauge• Diaphragm Chamber Connections• Manual Control Station• Main Drain Valve• System Drain Valve• Alarm Test Valve• Automatic Drain Valve• System Air Pressure Gauge• Air Supply Connections• Low Air Pressure Alarm Switch• Waterflow Pressure Alarm Switch

• Dry Pilot Actuator• Pressure Operated Relief Valve

To ease field assembly of the trim ar-rangement, the trim components areprovided par tially assembled asshown in Figure 2B.

The trim arrangement is provided withgalvanized or black nipples and fit-tings. The galvanized trim is intendedfor non-corrosive or corrosive condi-tions, whereas the black trim is princi-pally intended for use with AFFF sys-tems.

NOTEWhen the system pressure is greaterthan 175 psi (12,1 bar), provision is tobe made to replace the standard order300 psi (20,7 bar) Water PressureGauges, shown in Figure 2A/2B withseparately ordered 600 psi (41,4 bar)Water Pressure Gauges.

System Design ConsiderationsBecause a double interlock preactionsystem requires time for a drop in sys-tem air pressure to occur (concurrentlywith the response time for the separatefire detection system) before it will al-low water to enter the system piping,this system has characteristics similarto a dry pipe sprinkler system. There-fore, the system design considerationsfor a dry pipe system are normallyapplied to a double interlock preactionsystem — including a 30% increase indesign area; a maximum 1 minutewater delivery time for system capaci-ties of 750 gallons (2800 litres) ormore; and, prohibition of gridded sys-tem piping.

recommended that a System Shut-OffValve be installed above the RiserCheck Valve, as shown in Figure 1. TheSystem Shut-Off Valve should be alisted or approved (as appropriate) in-dicating valve with a supervisoryswitch to monitor the normally openposition.

Detection SystemThe Double Interlock Preaction Sys-tem With Electric/Pneumatic ActuationTrim provides for electric operation ofthe DV-5 Valve by a detection systemconsisting of electrical devices such asheat sensitive thermostats, smoke de-tectors, and/or electric manual pull sta-tions. Information on the various typesof separately ordered Solenoid Valvesthat may be used with this trim pack-age is given in Technical Data SheetTFP2180. Nominal installation dimen-sions for the Double Interlock Preac-tion System With Electric/PneumaticActuation Trim are shown in Figure 3.

The deluge valve releasing panel(automatic control unit) with batteryback-up, fire detection devices, man-ual pull stations, and signaling devicesthat are utilized with the Double Inter-lock Preaction System with Elec-tric/Pneumatic Actuation must be ULListed, ULC Listed, C-UL Listed, or FMApproved, as applicable.

NOTESApproval by Factory Mutual is contin-gent on the use of an FM Approved24VDC Solenoid Valve (P/N 52-287-1-024 or P/N 52-287-1-124). FM onlyapproves solenoid valves for use innon-hazardous locations.

Consult with the Authority Having Ju-risdiction regarding installation criteriapertaining to electric actuation cir-cuitry.

The Double Interlock Preaction Sys-tem With Electric/Pneumatic ActuationTrim is provided with a Model FSV-1Fail-Safe Valve (Item 5 - Fig. 2A, alsodescribed in Technical Data SheetTFP1386); consequently, the releasecircuit of the releasing panel need onlyprovide the standard ten minutes ofalarm condition intended to energizethe Solenoid Valve to open. After theten minute duration, at which pointshould the Solenoid Valve become de-energized and closes (especially whileoperating under battery back-up), theFail-Safe Valve will have already auto-matically operated to constantly ventthe DV-5 Diaphragm Chamber,thereby preventing the DV-5 Dia-phragm Chamber from becoming re-pressurized and preventing an inad-vertent closing of the DV-5 during a fireevent.

System Air Pressure RequirementsThe required system air pressure forthe Double Interlock Preaction Systemwith Electric/Pneumatic Actuation isshown in Graph A as a function of theanticipated water supply pressure. It isrecommended that the system airpressure be maintained by one of thefollowing methods:

• A maximum 200 psi (13,8 bar) plantair supply in combination with theModel AMD-1 Air Maintenance De-vice described in Technical DataSheet TFP1221.

• A dedicated air compressor in com-bination with the Model AMD-2 AirMaintenance Device described inTechnical Data Sheet TFP1231.

• A maximum 3000 psi (206,9 bar)nitrogen cylinder in combination withthe Model AMD-3 Nitrogen Mainte-nance Device described in Techni-cal Data Sheet TFP1241.

NOTESThe dew point of the air or nitrogensupply, for a system exposed to freez-ing conditions, must be maintained be-low the lowest ambient temperature towhich the system piping will be ex-posed. Introduction of moisture intothe system piping can create ice buildup which could prevent proper opera-tion of the system.

Friction LossThe nominal pressure loss versus flowdata for the Model DV-5 Deluge Valveplus Riser Check Valve is provided inGraph B.

InstallationNOTES

1-1/2 inch (DN40) risers utilize a 2 inch(DN50) Riser Check Valve in combina-tion with the 1-1/2 inch (DN40) ModelDV-5 Deluge Valve.

Proper operation of the Model DV-5Deluge Valves depends upon their trimbeing installed in accordance with theinstructions given in this TechnicalData Sheet. Failure to follow the ap-propriate trim diagram may preventthe DV-5 Valve from functioning prop-erly, as well as void listings, approvals,and the manufacturer’s warranties.

Field adjustments of the Air Mainte-nance Device, Low Pressure AlarmSwitch, and Pressure Relief Valve arerequired.

When using compressed air as op-posed to compressed nitrogen for re-frigerated area service, alternate airsupply connections with an air dryermay be required by the Authority Hav-ing Jurisdiction. The “1/2 Inch NPTConnection For System Air Supply”shown in Figure 2B is to be pluggedwhen using an alternate air supplyconnection; the location of the AirPressure Maintenance is to be asspecified by the Authority Having Ju-risdiction; and, Step 10 regarding theadjustment of the Pressure ReliefValve can be omitted, since the Pres-sure Relief Valve in this case will beineffective.

The DV-5 Valve must be installed in areadily visible and accessible location.

The DV-5 Valve and associated trimmust be maintained at a minimum tem-perature of 40°F/4°C.

Heat tracing of the DV-5 Valve or itsassociated trim is not permitted. Heattracing can result in the formation ofhardened mineral deposits that canprevent proper operation.

The Model DV-5 Deluge Valve is to beinstalled in accordance with the follow-ing criteria:

Step 1. All nipples, fittings, and de-vices must be clean and free of scaleand burrs before installation. Use pipethread sealant sparingly on male pipethreads only.

Step 2. The DV-5 Valve must betrimmed in accordance with Figure2A/2B.

Step 3. Care must be taken to ensurethat check valves, strainers, globevalves, etc. are installed with the flowarrows in the proper direction.

Step 4. Drain tubing to the drip funnel

Page 11 of 16TFP1460

must be installed with smooth bendsthat will not restrict flow.

Step 5. The main drain and drip funneldrain may be interconnected provideda check valve is located at least 12inches (300 mm) below the drip funnel.

Step 6. Suitable provision must bemade for disposal of drain water.Drainage water must be directed sothat it will not cause accidental dam-age to property or danger to persons.

Step 7. Connect the DiaphragmChamber Supply Control Valve to theinlet side of the system’s main controlvalve in order to facilitate setting of theDV-5 Valve (Fig. 3).

Step 8. Unused pressure alarmswitch connections must be plugged.

Step 9. A suitable automatic supervi-sory air (nitrogen) supply, as describedin the Technical Data Section, is to beinstalled in accordance with the appli-cable Technical Data Sheet. Refer toGraph A for the system air pressurerequirements.

An air dryer, when specified, is to beinstalled as required by the AuthorityHaving Jurisdiction.

Step 10. The Pressure Relief Valve(P6 - Fig. 2A) is factory set to relieve ata pressure of approximately 45 psi (3,1bar), which can typically be used for amaximum system pressure of 40 psi(2,8 bar). The Pressure Relief Valvemay be reset; however, it must be resetto relieve at a pressure that is in ac-cordance with the requirements of theAuthority Having Jurisdiction.

To reset the Pressure Relief Valve, firstloosen the jam nut and then adjust thecap accordingly — clockwise for ahigher pressure setting or counter-clockwise for a lower pressure setting.After verifying the desired pressuresetting, tighten the jam nut.

Step 11. The Low Pressure AlarmSwitch (Item P4 - Fig. 2A) is to beadjusted to operate on falling pressureat approximately 6 psi (0,4 bar) belowthe minimum Double Interlock DrySystem air pressure requirementshown on Graph B.

Use the instructions provided with theswitch to adjust the pressure setting.

Step 12. Conduit and electrical con-nections are to be made in accordancewith the requirements of the authorityhaving jurisdiction and/or the NationalElectric Code.

Step 13. Before a system hydrostatictest is performed in accordance withNFPA 13 system acceptance test re-quirements, the DV-5 DiaphragmChamber is to be depressurized; the

Automatic Drain Valve (4, Fig. 2A) is tobe temporarily replaced with a 1/2 inchNPT plug, the 3/32 inch Vent Fitting (17- Fig. 2A) is to be temporarily replacedwith a 1/4 inch NPT plug, and the Dia-phragm Cover Bolts must be uni-formly and securely tightened usinga cross-draw sequence. After tight-ening, double-check to make certainthat all of the Diaphragm Cover Boltsare securely tightened.

Valve SettingProcedureSteps 1 through 15 are to be per-formed when initially setting the ModelDV-5 Deluge Valve; after an opera-tional test of the fire protection system;or, after system operation due to a fire.

Step 1. Close the Main Control Valve.

Step 2. Close the Diaphragm Cham-ber Supply Control Valve and the Sys-tem Air Supply Control Valve.

Step 3. Open the Main Drain Valve,System Drain Valve, and all auxiliarydrains in the system. After waterceases to discharge, close the SystemDrain Valve and auxiliary drain valves.Leave the Main Drain Valve open.

NOTEDo not open the Inspector’s Test Con-nection and auxiliary drains if resettingafter a system test; otherwise, systemair pressure will be relieved unneces-sarily.

Step 4. Depress the plunger of theAutomatic Drain Valve to verify that itis open and that the DV-5 Valve iscompletely drained.

Step 5. Clean the Strainer in the Dia-phragm Chamber Supply connectionby removing the clean-out plug andstrainer basket. The Strainer may beflushed out by momentarily openingthe Diaphragm Chamber Supply Con-trol Valve.

Step 6. Inspect for and clear all iceplugs where system piping has beenexposed to freezing conditions andwhen there has been a flow of waterinto the system.

Step 7. Replace all damaged or oper-ated sprinklers. Replacement sprin-klers must be of the same type andtemperature rating as those that oper-ated.

NOTEIn order to prevent the possibility of asubsequent operation of an over-heated solder type sprinkler, any sol-der type sprinklers possibly exposed

to a temperature greater than theirmaximum rated ambient must also bereplaced.

Step 8. Service the air dryer, if appli-cable, in accordance with the manu-facturer’s instructions.

Step 9. Open the System Air SupplyControl Valve and allow the system toautomatically re-establish its nominalsystem air pressure per Graph A. Ob-serve the Automatic Drain Valve forleaks. If there are leaks, deter-mine/correct the cause of the leakageproblem within the Riser Check Valve.

Step 10. Reset the actuation system.

Manual Actuation — Push the operat-ing lever up; however, do not close thehinged cover at this time.

Electric Actuation — Reset the electricdetection system in accordance withthe manufacturer’s instructions to de-energize the Solenoid Valve.

Step 11. Open the Diaphragm Cham-ber Supply Control Valve and allow fullpressure to build up in the DiaphragmChamber.

Step 12. Operate (open) the ManualControl Station to vent trapped air fromthe Diaphragm Chamber. If necessary,first open the hinged cover, and thenfully pull down on the operating lever.SLOWLY close the operating lever, bypushing it up, after aerated waterceases to discharge from the ManualControl Station drain tubing. Close thehinged cover and insert a new breakrod in the small hole through the top ofthe enclosing box.

Step 13. Inspect the drain connectionsfrom the Manual Control Station andthe Dry Pilot Actuator. Any leaks mustbe corrected before proceeding to thenext step.

Step 14. Verify the ability for the DV-5Diaphragm to hold pressure as fol-lows:

With the diaphragm chamber pressur-ized per Step 12, temporarily close theDiaphragm Chamber Supply ControlValve and observe the DiaphragmChamber Pressure Gauge for a drop inpressure.

If a drop in pressure is noted, the DV-5Diaphragm is to be replaced and/orany leaks must be corrected beforeproceeding to the next step.

If the Diaphragm Chamber PressureGauge does not indicate a drop inpressure, re-open the DiaphragmChamber Supply Control Valve andproceed to the next step.

Step 15. Slowly open the Main ControlValve. Close the Main Drain Valve assoon as water discharges from the


drain connection. Observe the Auto-matic Drain Valve for leaks. If there areleaks, determine/correct the cause ofthe leakage problem. If there are noleaks, the DV-5 Valve is ready to beplaced in service and the Main ControlValve must then be fully opened.

NOTESWhen the Main Control Valve isopened, the pressure on the Dia-phragm Chamber may increase. Thisincrease in pressure is normal, and ifthe pressure is greater than 250 psi(17,2 bar), the pressure is to be re-lieved by partially and temporarilyopening the Manual Control Station;however, do not allow the pressure asindicated on the Diaphragm ChamberPressure Gauge to drop below thesupply pressure shown on the WaterSupply Pressure Gauge, since this ac-tion may result in tripping of the DV-5Valve.

After setting a fire protection system,notify the proper authorities and ad-vise those responsible for monitoringproprietary and/or central stationalarms.

Care andMaintenanceThe following procedures, inspections,and maintenance must be performedas indicated, in addition to any specificrequirements of the NFPA, and anyimpairment must be immediately cor-rected.

The owner is responsible for the in-spection, testing, and maintenance oftheir fire protection system and de-vices in compliance with this docu-ment, as well as with the applicablestandards of the National Fire Protec-tion Association (e.g., NFPA 25), inaddition to the standards of anyauthority having jurisdiction. The in-stalling contractor or product manufac-turer should be contacted relative toany questions.

It is recommended that automaticspr inkler systems be inspected,tested, and maintained by a qualifiedInspection Service in accordance withlocal requirements and/or nationalcodes.

It is recommended that the SystemInspection Procedure be performed atleast semi-annually by a qualified In-spection Service. The Double InterlockPreaction System Inspection Proce-dure may be followed in lieu of per-forming any of the operational testsrecommended in the Technical DataSheets for the Model DV-5 DelugeValve, Riser Check Valve, 24 VDC So-lenoid Valve, Dry Pilot Actuator, andModel MC-1 Manual Control Station.

NOTESIt is recommended that the individualsresponsible for the care and mainte-nance of the Double Interlock Preac-tion System develop a working under-standing of the system, in general,prior to performing inspection and/ormaintenance procedures. These in-structions, as well as individual in-structions for the deluge valve, risercheck valve, solenoid valve, dry pilotactuator, manual control station,switches, and pressure maintenancedevice should be reviewed.

The following procedures pertain tothe automatic control valve portion ofthe Double Interlock Preaction Sys-tem. Refer to the manufacturer’s in-structions and NFPA 25 for care andmaintenance procedures for all otherdevices (e.g., electric detection, maincontrol and system shut-off valves, su-pervisory devices, sprinklers, etc.).

Before performing the System Inspec-tion Procedure, which will result in op-eration of alarms, notify the proper

authorities and all personnel who maybe affected.

Before closing a fire protection systemmain control valve for maintenancework on the fire protection system thatit controls, permission to shut down theaffected fire protection system must beobtained from the proper authoritiesand all personnel who may be affectedby this action must be notified.

System Inspection Procedure

Step 1. Close the Main Control Valve(Fig. 1) and then open the DV-5 MainDrain Valve (Fig. 2B).

Step 2. Manually operate DelugeValve Releasing Panel, and verify thefollowing:

• Verify the operation of the ReleasingPanel and its associated alarms.

• Verify that there is no leakage fromthe Dry Pilot Actuator (Fig. 2B).

NOTESDuring this procedure, the SolenoidValve is opened; however, the Dry Pi-lot Actuator should remain closed andthe DV-5 Deluge Valve DiaphragmChamber should remain pressurized.

This procedure is used to verify thatthe DV-5 Deluge Valve will remain setif the electric detection system oper-ates but the sprinkler system remainsin its normally pressurized condition.

Step 3. Open the Inspector’s Test Con-nection but be prepared to close it im-mediately after verifying that the LowPressure Alarm Switch (Fig. 2B) andits associated alarms operate properly.The Low Pressure Alarm Switchshould operate at the previously estab-lished pressure (refer to Installationsection, Step 11).

Close the Inspector’s Test Connection.

Step 4. Close the Diaphragm ChamberSupply Control Valve (Fig. 2B).

Step 5. Close the System Shut-offValve (Fig. 1) after the system air pres-sure has been restored to normal.

Step 6. Manually restore the electricfire detection system to a normal con-dition in accordance with the manufac-turer’s instructions.The Solenoid Valvewill then be de-energized and returnedto its normally closed position.

Step 7. Open the Diaphragm ChamberSupply Control Valve (Fig. 2B).

Step 8. Open the Main Control Valve(Fig. 1) one turn beyond the position atwhich water just begins to flow fromthe Main Drain Valve.


Step 9. Close the Main Drain Valve(Fig. 2B).

Step 10. Close the Air Supply ControlValve (Fig. 2B).

Step 11. Open the Dry Pilot Actuatorby partially opening the System MainDrain Valve (Fig. 2B) to relieve air pres-sure at the inlet to the Actuator. Verifythat there is no leakage from the DryPilot Actuator.

NOTESDuring this procedure, the Dry PilotActuator is opened; however, the So-lenoid Valve should remain closed andthe DV-5 Deluge Valve DiaphragmChamber should remain pressurized.

This procedure is used to verify thatthe DV-5 Deluge Valve will remain setif the Dry Pilot Actuator operates dueto loss of system air pressure and theelectric detection system remains in anormal condition.

Step 12. Open (energize) the SolenoidValve by operating the deluge valvereleasing panel, and verify the follow-ing:

• Verify that the DV-5 Valve operates,as is indicated by a discharge ofwater from the System Main DrainValve and the Automatic DrainValve. The Automatic Drain Valvemay or may not close depending onthe flow past the partially open MainControl Valve.

• Verify that the Model FSV-1 Fail-Safe Valve has operated as is indi-cated by water discharging into theDrip Funnel from the 1/2 inch draintube connected to the Model FSV-1Fail-Safe Valve.

• Verify that the Waterflow PressureAlarm Switch (Fig. 2B) and its asso-ciated alarms properly operate.

• Verify that the Water Motor Alarm, ifapplicable, properly operates.

NOTE

This procedure simulates opening ofboth the Dry Pilot Actuator (loss ofsystem air pressure) and SolenoidValve (operation of the deluge valvereleasing panel) to verify automaticsystem operation.

Step 13. Reset the Double InterlockPreaction System in accordance withthe Resetting Procedure section.

Fail-Safe Valve

If water does not discharge from the1/2 inch tube connected to the ModelFSV-1 Fail-Safe Valve during Step 12of the System Inspection Procedure,the Model FSV-1 Fail-Safe Valve is tobe disassembled, cleaned, and in-spected as follows:

Step 1. Take the sprinkler system outof service by using Steps 1 through 4of the Resetting Procedure.

Step 2. Remove the FSV-1 from theDouble Interlock Preaction Trim.

Step 3. Refer to Technical Data SheetTFP1386 and completely disassem-ble the FSV-1.

Step 4. Clean all parts, and replaceworn or damaged parts as necessary

Step 5. Reassemble the FSV-1 in ac-cordance with Technical Data SheetTFP1386 and then reinstall the FSV-1into the Double Interlock PreactionTrim.

Step 6. Place the system into servicein accordance with the Resetting Pro-cedure section and then perform theSystem Inspection Procedure to verifyproper operation of the system, as wellas the FSV-1 Fail-Safe Valve.

Quarterly Waterflow Alarm TestProcedureTesting of the system waterflow alarmsmust be performed quarterly. To testthe waterflow alarm, open the AlarmTest Valve, which will allow a flow ofwater to the Waterflow Pressure AlarmSwitch and/or Water Motor Alarm.Upon satisfactory completion of thetest, close the Alarm Test Valve.
