Model DV-5 Deluge Valve, Diaphragm Style, 1-1/2...

GeneralDescriptionThe 1-1/2 thru 8 inch (DN40 thruDN200), Model DV-5 Deluge Valvesare diaphragm type valves designedfor vertical or horizontal installationand for fire protection system service.They are used as “automatic watercontrol valves” in deluge, preaction,and special types of fire protection sys-tems such as foam-water and doubleinterlock systems. When properlytrimmed, the DV-5 Valves are alsoable to provide actuation of fire alarmsupon system operation.

The diaphragm style design of theDV-5 Valve allows external resetting— providing for easy resetting of adeluge or preaction system withouthaving to open a valve handhole coverto manually reposition a clapperand/or latch mechanism. Simply re-pressurizing the diaphragm chamberresets the valve.

The one-piece, diaphragm style de-sign of the DV-5 also allows internaland external coating of the valve toprovide corrosion resistance. The in-ternal corrosion resistance offered bythe Rilsan coating makes the DV-5suitable for most seawater and brack-ish water supplies when utilized in del-uge systems. The external corrosionresistance of the Rilsan coating per-mits the use of the DV-5 in corrosiveatmospheres associated with manytypes of industrial processing plantsand outdoor installations.

WARNINGThe Model DV-5 Deluge Valves de-scribed herein must be installed andmaintained in compliance with thisdocument, as well as with the applica-ble standards of the National Fire Pro-tection Association, in addition to thestandards of any other authorities hav-ing jurisdiction. Failure to do so mayimpair the performance of these de-vices.

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.

Materials OfConstruction

NOTESThe Rilsan coating for the DV-5 Valveprovides corrosion resistance and isintended to extend the life of the DV-5Valve when exposed to internal andexternal corrosive conditions. Al-though the Rilsan coating is intendedto resist corrosion, it is recommendedthat the end user or other technicalexpert familiar with conditions at theproposed installation be consultedwith respect to the suitability of thiscoating for a given corrosive condition.

Deluge systems using a seawater orbrackish water supply require specialconsiderations in order to extend thelife of the valve and trim. This type ofsystem ideally should be configuredwith a primary source of clean freshwater (e.g., a pressurized water tank)and only upon system operation is thesecondary water supply (seawater orbrackish water) allowed to enter thesystem. After the system operation,the system should then be thoroughlyflushed with clean fresh water. Follow-ing this recommendation will increasethe service life of the DV-5 Valve andValve Trim.

Body. Rilsan* coated ductile iron perASTM A536-77, Grade 65-45-12.

Handhole Cover. Rilsan* coated duc-tile iron per ASTM A536-77, Grade65-45-12.

OperatingPrinciplesThe Model DV-5 Deluge Valve is adiaphragm style valve that dependsupon water pressure in the DiaphragmChamber (Ref. Figure 2A) 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. Open-

ing an actuation device, for examplethe solenoid valve in the Electric Ac-tuation Trim (Ref. Technical DataSheet TFP1320), releases water fromthe Diaphragm Chamber faster than itcan be replenished through an 1/8 inch(3,2 mm) restriction provided by thediaphragm chamber supply connec-tion provided in the applicable trim ar-rangements. This results in a rapidpressure drop in the DiaphragmChamber and the force differential ap-plied through the Diaphragm to holdthe Diaphragm in the set position is

reduced below the valve trip point. Thewater supply pressure then forces theDiaphragm open permitting water toflow into the system piping, as well asthrough the Alarm Port to actuate thesystem alarms (Ref. Figure 2B).

OperatingPrinciplesThe Tyco® Aluminum Bronze ModelDV-5 Deluge Valve is a diaphragmstyle valve that depends upon waterpressure in the Diaphragm Chamber(Ref. Figure 2A) to hold the Diaphragmclosed against the water supply pres-sure. When the DV-5 Valve is set forservice, the Diaphragm Chamber ispressurized through the trim connec-tions from the inlet side of the system’smain control valve. Opening an actua-tion device, releases water from theDiaphragm Chamber faster than it canbe replenished through an 1/8 inch(3,2 mm) restriction provided in thediaphragm chamber supply connec-tion. This results in a rapid pressuredrop in the Diaphragm Chamber andthe force differential applied throughthe Diaphragm to hold the Diaphragmin the set position is reduced below thevalve trip point. The water supply pres-sure then forces the Diaphragm openpermitting water to flow into the systempiping.

GeneralDescriptionThe 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, forexample an O.S.&Y. gate valve or but-terfly valve (Ref. Figures 1 and 3).

Opening of a wet pilot sprinkler, re-leases water from the DiaphragmChamber faster than it can be replen-ished through the 1/8 inch (3,2 mm)restriction provided by the ModelASV-1 Automatic Shut-Off Valve in thediaphragm supply connections (Item 5- Fig. 2A and 4, also described in Tech-nical Data Sheet TFP1384). This re-sults in a rapid pressure drop in theDiaphragm Chamber and the force dif-ferential applied through the Dia-phragm that holds it in the set positionis reduced below the valve trip point.The water supply pressure then forcesthe Diaphragm open permitting waterto flow into the system piping, as wellas through the Alarm Port to actuatethe system alarms.

As water flows into the system, thepilot chamber of the Model ASV-1Automatic Shut-Off Valve (Item 5 - Fig.2A and 4) becomes pressurized andthe ASV-1 automatically shuts off thediaphragm chamber supply flow to theDV-5 Diaphragm Chamber. Shuttingoff the diaphragm chamber supply flowprevents the DV-5 Diaphragm Cham-ber from becoming re-pressurized,thereby preventing inadvertent closingof the DV-5 during a fire (as may be thecase if an actuation device other thana pilot sprinkler were to be closed afterits initial operation, for example a re-mote manual control station).

WARNINGThe Model DV-5 Deluge Valve withWet Pilot Actuation Trim describedherein must be installed and main-tained in compliance with this docu-ment, as well as with the applicablestandards of the National Fire Protec-tion Association, in addition to thestandards of any other authorities hav-ing jurisdiction. Failure to do so mayimpair the performance of these de-vices.

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.

Operation of an electrical device suchas a heat sensitive thermostat, smokedetector, or electrical manual controlstation signals the deluge valve releas-ing panel to energize the SolenoidValve. In turn, the energized SolenoidValve opens to release water from theDiaphragm Chamber faster than it canbe replenished through the 1/8 inch(3,2 mm) restriction provided by theModel ASV-1 Automatic Shut-OffValve in the diaphragm supply connec-tions (Item 5 - Fig. 2A and 4, alsodescribed in Technical Data SheetTFP1384). This results in a rapid pres-sure drop in the Diaphragm Chamberand the force differential appliedthrough the Diaphragm that holds it inthe set position is reduced below thevalve trip point. The water supply pres-sure then forces the Diaphragm openpermitting water to flow into the systempiping, as well as through the AlarmPort to actuate the system alarms.

As water flows into the system, thepilot chamber of the Model ASV-1Automatic Shut-Off Valve (Item 5 - Fig.2A and 4) becomes pressurized andthe ASV-1 automatically shuts off thediaphragm chamber supply flow to theDV-5 Diaphragm Chamber. Shuttingoff the diaphragm chamber supply flowprevents the DV-5 Diaphragm Cham-ber from becoming re-pressurized,thereby preventing inadvertent closing

of the DV-5 during a fire (as may be thecase should the Solenoid Valve be-come de-energized after its initial op-eration).

Materials of ConstructionNOTICE

The Rilsan* coating for the Model DV-5 Deluge Valve with Remote-Resetting Trim provides corrosion resistance and is intended to extend the life of the Valve when exposed to internal and external corrosive conditions. Al though the Rilsan coating is intended to resist corrosion, it is recommended that the end user or other technical expert familiar with conditions at the proposed installation be consulted with respect to the suitability of this coating for a given corrosive condition.

Deluge systems using a seawater or brackish water supply require special considerations in order to extend the life of the valve and trim. This type of system ideally should be configured with a primary source of clean fresh water and only upon system operation is the secondary water supply (seawater or brackish water) allowed to enter the system.

After system operation, the system should then be thoroughly flushed with clean fresh water. Follow ing this recommendation can increase the service life of the Model DV-5 Deluge Valve with Remote-Resetting Trim.

Vertical Valve Trim (Ordered Separately for the Americas)The Solenoid Valve and Waterflow Pressure Alarm Switch, provided as standard with only the VdS Trim, are for use in non-hazardous locations; that is, locations where potentially explosive atmospheres are not present. These parts are separately ordered for the UL Trim.

Design Criteria The following items must be consid-ered and applied accordingly for TYCO Model DV-5 Deluge Valve with Remote-Resetting Trim installations.

NOTICEResponsibility lies with owners to design into the system a releasing circuit such that a Solenoid Valve is properly configured to enable remote resetting.

The building owner must be informed of the capabilities and limitations of a remote-resetting system as it pertains to the possibility of an inadvertent manual closing of the Model DV-5 Deluge Valve during a fire condition. Therefore, personnel responsible for the fire protection system must be fully trained on system components and required actions in the case of an alarm.

The Control Panel, Detectors, and Pull Stations are to be installed in accor-dance with their laboratory listings and approval.

System piping is to be installed so that it is self-draining. TYCO Model AD-2 Automatic Drain Valves can be used to drain low sections of pipe as necessary. For more information, refer to technical data sheet TFP1632.

OperationThe TYCO Remote-Resetting System includes a differential valve that uses water pressure in the Diaphragm Chamber (Figures 3 and 4) to hold the Diaphragm closed against the water supply pressure.

When the Model DV-5 Valve with Remote-Resetting Trim is set for service, the Diaphragm Chamber is pressurized through the trim connec-tions from the inlet side of the system’s main control/shut-off valve, for example an O.S.&Y. gate valve or butterfly valve.

Opening of the Solenoid Valve in the Remote-Resetting Trim releases water from the Diaphragm Chamber faster than it can be replenished through the Restriction in the Diaphragm Chamber Supply Connection provided

in the trim. This release results in a rapid pressure drop in the Diaphragm Chamber, and the force differential applied through the Diaphragm that holds it in the set position is reduced below the valve trip point.

The water supply pressure then forces the Diaphragm open, permitting water to flow into the system piping, as well as through the Alarm Port to actuate system alarms.

Closing of the Solenoid Valve in the Remote-Resetting Trim permits the Diaphragm Chamber to repres-surize. This repressurizing results in a pressure increase in the Diaphragm Chamber. The resulting force repres-surizes the Diaphragm Chamber, closing the valve and stopping the flow of water into the system piping.

InstallationNOTICE

Proper operation of the Model DV-5 Deluge Valve with Remote-Resetting Trim depends upon trim installed in accordance with the instructions given in this technical data sheet. Failure to follow the appropriate trim diagram may prevent the valve from functioning properly, may void the manufactur-er’s warranty, and will void listings and approvals.

The Model DV-5 Deluge Valve and associated trim must be maintained at a minimum temperature of 40°F (4°C).

Heat tracing of the Model DV-5 Deluge Valve or its associated trim is not permitted. Heat tracing can result in the formation of hardened mineral deposits that are capable of preventing proper operation.

General DescriptionThe TYCO Model DV-5 Deluge Valve with Remote-Resetting, Pressure-Reducing Trim is a diaphragm-style valve that depends upon water pres-sure in the Diaphragm Chamber to hold the Diaphragm closed against water supply pressure. Key features include the following:

•Pressure-reducing function maintains pre-set outlet pressure.

•Remote-resetting feature provides the ability to reset the valve from one or more locations.

•Compact, space-saving design re-duces valve room footprint and con-struction costs.

Operation of an electrical device, such as a heat sensitive thermostat, smoke detector, or electrical manual control station, signals the releasing panel to energize the Solenoid Valve. In turn, the energized Solenoid Valve, which is normally closed, opens to release wa-ter from the Diaphragm Chamber. This action results in a rapid pressure drop in the Diaphragm Chamber.

The force differential applied through the Diaphragm that holds it in the set position is reduced below the Valve trip point. Water supply pressure then forc-es the Diaphragm open, permitting wa-ter to flow into the system piping and through the Alarm Port, actuating sys-tem alarms.

When the valve is activated, system outlet pressure is determined by the Pilot Valve’s set point. The Diaphragm regulates downstream pressure based on this setting.

The Pilot Valve can be used in various applications and configurations, and should be installed according to the valve’s application scheme, honoring the Pilot Valve’s working conditions described herein. For other configura-tions, contact a TYCO Representative.

NOTICEThe Model DV-5 Deluge Valve with Remote-Resetting, Pressure-Reducing Trim described herein must be installed and maintained in compliance with this document as well as with the applicable installation and testing standards (for example, NPFA 13 and 25), in addition to the standards of any local Authorities Having Jurisdiction. Failure to do so may impair the performance of these devices.

Owners are responsible for maintaining their fire protection system and devices in proper operating condition. The in-stalling contractor or sprinkler manu-facturer should be contacted with any questions.

Pressure-Reducing Pilot ValveThe Pilot Valve operates when hydraulic pressure is applied below the spring-loaded membrane. The spring’s tension upon the membrane can be adjusted (increased by the Adjusting Screw). The membrane is connected to the Pilot Valve’s seal trim, opening and closing the Pilot Valve’s water passage.

The Pilot Valve is normally Open. When no pressure is applied below the spring-loaded membrane, the Pilot Valve allows the deluge valve to open. Once pipeline pressure is built down-stream of the deluge valve, this pres-sure is conveyed to the Pilot Valve’s membrane through the sensor port. When the pressure surpasses the set point (pre-adjusted through the Pilot Valve’s Adjusting Screw), the mem-brane moves upwards and water pas-sage ceases, closing the deluge Valve.

When the downstream pressure reduc-es below the Pilot Valve’s set point, the membrane moves downwards, opening the water passage, allowing the deluge valve to open.

The Pilot Valve is mounted with a prim-ing supply restriction between the Main Valve’s upstream and the Pilot Valve’s inlet. The valve is a 2-way pilot. During operation, water circulates constantly through the Pilot Valve, providing an immediate response to any changes in pipeline pressure.

NOTICEThe spring range should be appropriate to desired working conditions (required preset value). To verify the spring’s pressure range, check the colored ring and compare to the spring range table.

Materials of ConstructionNOTICE

The galvanized or brass nipples and fittings for the Valve Trim provide cor-rosion resistance and are intended to extend the life of the installation of the Model DV-5 Valve with Remote-Resetting, Pressure-Reducing Trim when exposed to internal and external corrosive conditions. Although these selections are intended to resist cor-rosion, it is recommended that the end user or other technical expert familiar with conditions at the proposed in-stallation be consulted with respect to these selections for a given corrosive condition.

Systems using a seawater or brack-ish water supply require special con-siderations in order to extend the life of the valve and trim. This type of sys-tem ideally should be configured with a primary source of clean fresh water and that only upon system operation is the secondary water supply (seawater

or brackish water) allowed to enter the system. After the system operation, the system should be thoroughly flushed with clean fresh water.

Following this recommendation can increase the service life of the Model DV-5 Deluge Valve with Remote-Resetting, Pressure-Reducing Trim.

GeneralDescriptionThe Model DV-5 Supervised Single In-terlock Preaction System with Wet Pi-lot Actuation (Fig. 1) utilizes automaticsprinklers and a supplemental detec-tion system. The supplemental detec-tion system is comprised of wet pilotlines and pilot sprinklers. Actuation ofthe detection system automatically op-erates (releases) the Model DV-5 Del-uge Valve, allowing water to flow intothe sprinkler piping system and to bedischarged from any sprinklers thatmay be open.

In accordance with the requirementsof the National Fire Protection Asso-ciation, a preaction system employingmore than 20 automatic sprinklers is tohave the sprinkler piping automaticallysupervised to monitor the overall in-tegrity of the system. In the case of aSupervised Single Interlock PreactionSystem, a Riser Check Valve (thatdoes not require the use of primingwater) provides an air check so thatthe system can be automatically pres-surized with a nominal supervisory airor nitrogen pressure of 10 psi (0,69bar). A supervisory low pressure alarmswitch that is set to transfer its contactsat nominally 5 psi (0,34 bar), on de-creasing pressure, is utilized to indi-cate whether there are any abnormalleaks in the sprinkler system piping.Loss of air pressure from the systemas a result of a damaged sprinkler orbroken piping will not cause the DV-5Valve to open — the air pressure is forsupervisory alarm only.

Typically, the system designer selectsthe detection components for a singleinterlock preaction system that will re-spond to a fire sooner than the auto-matic sprinklers. Consequently, thesystem will experience a minimal delayin water delivery over that for a wetpipe sprinkler system because thesystem will have essentially filled withwater before a sprinkler operates. In

the case of wet pilot actuation, thesystem designer selects wet pilotsprinklers that will operate sooner thanthe automatic sprinklers chosen foruse on the sprinkler piping.

Supervised single interlock preactionsystems are generally used to protectareas where there is danger of seriouswater damage that might result fromdamaged automatic sprinklers or pip-ing. Typically, such areas include com-puter rooms, storage areas for valu-able artifacts, libraries, and archives.

Single interlock preaction systems are

also effectively used to protect proper-ties where a pre-alarm of a possiblefire condition may allow time for fireextinguishment by alternate suppres-sion means, prior to a sprinkler dis-charge. In the event the fire cannototherwise be extinguished, the preac-tion sprinkler system will then performas the primary fire protection system.

GeneralDescriptionThe Model DV-5 Supervised Single In-terlock Preaction System with Dry PilotActuation (Fig. 1) utilizes automaticsprinklers and a supplemental detec-tion system. The supplemental detec-tion system is comprised of dry pilotlines and pilot sprinklers. Actuation ofthe detection system automatically op-erates (releases) the Model DV-5 Del-uge Valve, allowing water to flow intothe sprinkler piping system and to bedischarged from any sprinklers thatmay be open.


Typically, the system designer selectsthe detection components for a singleinterlock preaction system that will re-spond to a fire sooner than the auto-matic sprinklers. Consequently, thesystem will experience a minimal delayin water delivery over that for a wetpipe sprinkler system because thesystem will have essentially filled withwater before a sprinkler operates. In

the case of dry pilot actuation, the sys-tem designer selects pilot sprinklersthat will operate sooner than the auto-matic sprinklers chosen for use on thesprinkler piping.


Single interlock preaction systems are

also effectively used to protect proper-ties where a pre-alarm of a possiblefire condition may allow time for fireextinguishment by alternate suppres-sion means, prior to a sprinkler dis-charge. In the event the fire cannototherwise be extinguished, the preac-tion sprinkler system will then performas the primary fire protection system.

The Model DV-5 Deluge Valve (de-scribed in Technical Data SheetTFP1305) is a diaphragm style valvethat depends upon water pressure in

Opening of a pilot sprinkler, releasespneumatic pressure from the pilot line.In turn, the Dry Pilot Actuator (Item D3- Fig. 2A) opens and releases waterfrom the Diaphragm Chamber fasterthan it can be replenished through the1/8 inch (3,2 mm) restriction providedby the Model ASV-1 Automatic Shut-Off Valve in the diaphragm supply con-nection (Item 5 - Fig. 2A, also de-scribed in Technical Data SheetTFP1384). This results in a rapid pres-sure drop in the Diaphragm Chamberto below the valve trip point. The watersupply pressure then forces the Dia-phragm open, permitting water to flowinto the system piping, as well asthrough the Alarm Port to actuate thesystem alarms

As water flows into the system, thepilot chamber of the Model ASV-1Automatic Shut-Off Valve (Item 5 - Fig.2A) becomes pressurized and theASV-1 automatically shuts off the dia-phragm chamber supply flow to theDV-5 Diaphragm Chamber. Shuttingoff the diaphragm chamber supply flowprevents the DV-5 Diaphragm Cham-ber from becoming re-pressurized,thereby preventing inadvertent closingof the DV-5 during a fire (as may be thecase if an actuation device other thana pilot sprinkler were to be closed afterits initial operation, for example a re-mote manual control station).

Detection SystemIn order for a single interlock preactionsystem to be hydraulically calculatedas a wet pipe system, as opposed to adry pipe sprinkler system, the detec-tion system must be designed to oper-ate sooner than the automatic sprin-klers on the sprinkler piping. In thecase of dry pilot actuation, the systemdesigner selects pilot sprinklers thatwill operate sooner than the automaticsprinklers chosen for use on the sprin-kler piping.

The Supervised Single Interlock Pre-action System With Dry Pilot ActuationTrim provides for connection of a de-tection system consisting of dry pilotline sprinklers (heat detectors) andmanual control stations intercon-nected with minimum 1/2 inch (DN15)Schedule 40 steel pipe. The pilot line,which is pressurized with air or nitro-gen, is connected to the “Dry Pilot De-tection” connection shown in Figure2B.

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 Supervised Single Inter-lock Preaction System With ElectricActuation Trim are shown in Figure 3.

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.

The Supervised Single Interlock Pre-action System With Electric ActuationTrim is provided with a Model ASV-1Automatic Shut-Off Valve (Item 5 - Fig.2A); consequently, the release circuitof the releasing panel need only pro-vide the standard ten minutes of alarmcondition intended to energize the So-lenoid Valve. After the ten minute du-ration, should the Solenoid Valve be-come de-energized and close(especially while operating under bat-tery back-up), the Automatic Shut-OffValve will have already automaticallyclosed thereby preventing the DV-5Diaphragm Chamber from becomingre-pressurized and preventing an in-advertent closing of the DV-5 during afire event.

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

GeneralDescriptionThe Tyco® Model DV-5 Double Inter-lock Preaction System with Elec-tric/Electric Actuation (Fig. 1) is de-signed for use in applications, such asrefrigerated areas, requiring the maxi-mum degree of protection against in-advertent flooding of the sprinkler sys-tem piping.

The Model DV-5 Double Interlock Pre-action System with Electric/ElectricActuation utilizes a Model DV-5 Del-uge Valve and a Riser Check Valve.The Riser Check Valve (that does notrequire the use of priming water) iso-lates the Deluge Valve from the sys-tem air pressure. The releasing trim forthe Deluge Valve utilizes a SolenoidValve that is operated by energizingthe releasing circuit of a Cross-ZoneDeluge Valve Releasing Panel (auto-matic control unit).

Zone 1 of the Releasing Panel is oper-ated by either a fire detection device ormanual pull station. Zone 2 of the Re-leasing Panel is operated by a Low AirPressure Alarm Switch in response toa loss of system air pressure due to theopening of an automatic sprinkler. TheSolenoid Valve remains closed until itis electrically energized by the Releas-ing Panel.

In order for the Double Interlock Pre-action System to automatically actu-ate, two independent events must oc-cur. Zone 1 of the Releasing Panelmust operate upon automatic opera-tion of the electric fire detection initiat-ing circuit or operation of the electric-manual pull initiating circuit, and Zone2 of the Releasing Panel must operatevia the Low Air Pressure Alarm Switchupon loss of air pressure from thesprinkler system piping, due to opera-tion of one or more sprinklers.

The Double Interlock Preaction Sys-tem will automatically actuate onlywhen both Zone 1 and Zone 2 of the

Releasing Panel have operated, ener-gizing the Solenoid Valve. Accidentalloss of system air pressure (for exam-ple: a lift truck accidentally dislodges asprinkler), or operation of just the firedetection circuit (for example: an acci-dental operation of an electric pull sta-tion), will only cause an alarm, and willnot actuate the system or flood thesprinkler system 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 water

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

Operation the Solenoid Valve releaseswater from the Diaphragm Chamberfaster than it can be replenishedthrough the 1/8 inch (3,2 mm) restric-tion provided by the Model ASV-1Automatic Shut-Off Valve in the dia-phragm supply connections (Item 5 -Fig. 2A, also described in Technical
