preaction system double interlock-elect-elect actuation

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

MINIMUM CLEARANCE.*

Data Sheet TFP1384). This results ina rapid pressure drop in the Dia-phragm Chamber below the valve trippoint. The water supply pressure thenforces the Diaphragm open permittingwater to flow into the system piping, aswell as through the Alarm Port to actu-ate the system 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 should the Solenoid Valve be-come de-energized after its initial op-eration).

NOTICE

The Model DV-5 Double Interlock Pre-action System with Electric/ElectricActuation described herein must beinstalled and maintained in compli-ance with this document and with theapplicable standards of the NationalFire Protection Association, in additionto the standards of any authorities hav-ing jurisdiction. Failure to do so mayimpair the performance of the relateddevices.

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.

Note:1-1/2 inch (DN40) risers utilize a2 inch (DN50) Riser Check Valve incombination with the 1-1/2 (DN40)Model DV-5 Deluge Valve.

Valve TrimThe Double Interlock Preaction Sys-tem with Electric/Electric 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

To ease field assembly of the trim ar-rangement, the trim components areprovided partially 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.

Note: When the system pressure isgreater than 175 psi (12,1 bar), provi-sion is to be made to replace the stand-ard order 300 psi (20,7 bar) WaterPressure Gauges, shown in Figure2A/2B with separately 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 willallow 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 normally ap-plied 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.

As an option the Model DV-5 DoubleInterlock Preaction System with Elec-tric/Electric Actuation may beequipped with the Model QRS Elec-tronic Accelerator to reduce the thetime to valve actuation following theoperation of the electric detection sys-tem and one or more automatic sprin-klers. Refer to Technical Data SheetTFP1100 for details regarding installa-tion requirements and pressure rat-ings.

In order to readily perform the SystemInspection Procedure described in theCare and Maintenance section, it isrecommended that a System Shut-OffValve be installed above the RiserCheck Valve, as shown in Figure 1.The System Shut-Off Valve should bea listed or approved (as appropriate)indicating valve with a supervisoryswitch to monitor the normally openposition.

Detection SystemThe Double Interlock Preaction Sys-tem With Electric/Electric 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/Electric Ac-tuation Trim are shown in Figure 3.

The cross-zone deluge valve releasingpanel (automatic control unit) with bat-tery back-up, fire detection devices,manual pull stations, and signaling de-vices, that are utilized with the DoubleInterlock Preaction System with Elec-tric/Electric Actuation must be ULListed, ULC Listed, C-UL Listed, or FMApproved, as applicable.

Note: Approval by Factory Mutual iscontingent on the use of an FM Ap-proved 24VDC Solenoid Valve (P/N52-287-1-024 or P/N 52-287-1-124).FM only approves solenoid valves foruse in non-hazardous locations.

Note: Consult with the Authority Hav-ing Jurisdiction regarding installationcriteria pertaining to electric actuationcircuitry.

The Double Interlock Preaction Sys-tem With Electric/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 to open. After the tenminute duration, at which point shouldthe Solenoid Valve become de-ener-gized and close (especially while oper-ating under battery back-up), the Auto-matic Shut-Off Valve will have alreadyautomatically closed, thereby prevent-ing the DV-5 Diaphragm Chamberfrom becoming re-pressurized andpreventing an inadvertent closing ofthe DV-5 during a fire event.

sure for the Double Interlock PreactionSystem with Electric/Electric Actuationis nominally 15 psi (1,0 bar), irrespec-tive of the water supply pressure. Theuse of a higher system air pressuremay increase water delivery time, andthe use of a lower system air pressuremay prevent clearing the alarm of theLow Air Pressure Alarm Switch (ItemP3 - Fig. 2A) on increasing pressure.The Low Pressure Alarm Switch isfield set to alarm at nominally 12 psi(0,8 bar) on decreasing pressure. It isrecommended that the system airpressure be maintained by either ofthe following 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 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.

NOTESIt is recommended that the pressuremaintenance device be of a type thatmaintains a constant system pressure,i.e., a pressure maintenance devicethat utilizes a pressure regulator ver-sus a pressure switch (e.g., the AMD-1or AMD-3). Use of a pressure switchoperated pressure maintenance de-vice with a cut-in/cut-out differentialmay result in a delay in the operationof the system due to a fire, because ofthe cut-out pressure being higher thanthe recommended nominal system airpressure.

The 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.

The Pressure Relief Valve (Item P4-Fig. 2A) is typically field set to crackopen at a pressure of about 20 psi (1,4bar).

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

InstallationNOTICE

1-1/2 inch (DN40) risers utilize a 2 inch(DN50) Riser Check Valve in combina-tion with the 1-1/2 (DN40) Model DV-5Deluge 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. The Air Maintenance Deviceand the Low Pressure Alarm Switchshould be set as close as possible tothe specified settings in order to mini-mize water delivery time.

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 Tyco® Model DV-5 Deluge Valveis to be installed in accordance withthe following 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 (or TFP1100 when using ModelQRS Electronic Accelerator)

Step 3. Care must be taken to ensure

that check valves, strainers, globevalves, etc. are installed with the flowarrows in the proper direction.

Step 4. Drain tubing to the drip funnelmust 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 de-scribed in the Technical Data Section,is to be installed in accordance withthe applicable Technical Data Sheetand set to maintain nominally 15 psi(1,0 bar).

Step 10. Adjust the Pressure ReliefValve (P4-Fig. 2A), as applicable, tocrack open at approximately 20 psi(1,4 bar). As shipped, it is set to openat approximately 45 psi (3,1 bar).

To reset the Pressure Relief Valve,first loosen the jam nut and then adjustthe cap 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. Adjust the Low PressureAlarm Switch (P3-Fig. 2A) to transferthe electrical contacts at nominally 12psi (0,8 bar) on decreasing pressure.As shipped, the switch is set to transferthe electrical contacts at approxi-mately 5 psi (0,3 bar) on decreasingpressure.

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.

NOTICE

The heat detection devices are to beconnected to the Zone 1 initiating cir-cuit contacts of the Cross-Zone Del-uge Valve Releasing Panel.

The Low Air Pressure Alarm Switch

of 14TFP1465

contacts are to be connected to theZone 2 initiating circuit contacts of theCross-Zone Deluge Valve ReleasingPanel.

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; theAutomatic Drain Valve (4, Fig. 2A) is tobe temporarily replaced with a 1/2 inchNPT plug, the 3/32 inch Vent Fitting(16 - Fig. 2A) is to be temporarily re-placed with a 1/4 inch NPT plug, andthe Diaphragm Cover Bolts must beuniformly and securely tightenedusing a cross-draw sequence. Aftertightening, double-check to make cer-tain that all of the Diaphragm CoverBolts are securely tightened.

Valve SettingProcedureSteps 1 through 15 are to be per-formed when initially setting the Tyco®

Model DV-5 Deluge Valve; after anoperational test of the fire protectionsystem; or, after system operation dueto 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.

Note: Do not open the Inspector’s TestConnection and auxiliary drains if re-setting after a system test; otherwise,system air pressure will be relievedunnecessarily.

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.

NOTICE

In order to prevent the possibility of asubsequent operation of an over-heated solder type sprinkler, any sol-der type sprinklers that were possiblyexposed to a temperature greater thantheir maximum rated ambient mustalso be replaced.

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 nominalair pressure of 15 psi (1,0 bar). 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.

Note: For systems eqipped with theModel QRS Electronic Accelerator in-stalled per Technical Data SheetTFP1100, momentarily press the “Sys-tem Reset” button (Figure 6 inTFP1100). Zone 1 Alarm and Zone 2Low Air Alarm should then clear.

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 neces-sary, first open the hinged cover, andthen fully 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 enclosing box.

Step 13. Inspect the drain connectionsfrom the Manual Control Station andthe Solenoid Valve. Any leaks must becorrected 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 the

Diaphragm Chamber Supply ControlValve, and monitor the DiaphragmChamber Pressure Gauge for a dropin pressure.

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 thedrain 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.

NOTICE

When 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.

Automatic sprinkler systems are rec-ommended to be inspected, tested,and maintained by a qualified Inspec-tion Service in accordance with localrequirements and/or national codes.

It is recommended that the SystemInspection Procedure be performed atleast semi-annually by a qualified In-spection Service. The Double Inter-lock Preaction System Inspection Pro-cedure may be followed in lieu ofperforming any of the operational testsrecommended in the Technical DataSheets for the Model DV-5 DelugeValve, Riser Check Valve, 24 VDC So-lenoid Valve, and Model MC-1 ManualControl Station.

NOTICE

It 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, manualcontrol station, switches, and pressuremaintenance device should be re-viewed.

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 properauthorities 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 Zone 1 of theReleasing Panel, and verify the follow-ing:

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

• Verify that there is no leakage fromthe Solenoid Valve (Fig. 2B).

Note: During this procedure, the Sole-noid 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 electric detection system(Zone 1)operates but the sprinkler system(Zone 2) remains in its normally pres-surized condition.

Step 4. Restore the electric fire detec-tion system to a normal condition inaccordance with the manufacturer’sinstructions.

Step 5. Open the Inspector’s TestConnection to relieve system air pres-sure, and verify the following:

• Verify that the Low Air PressureAlarm Switch (Fig. 2B) and Zone 2of the Releasing Panel, as well as itsassociated alarms, operate prop-erly. The Low Pressure AlarmSwitch should operate at approxi-mately 12 psi (0,8 bar).

• Verify that there is no leakage fromthe Solenoid Valve (Fig. 2B).

Close the Inspector’s Test Connec-tion.

Note: During this procedure, the Sole-noid 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 Low Pressure Alarm Switch(Zone 2) operates due to loss of sys-tem air pressure and the electric de-tection system (Zone 1) remains in anormal condition.

Step 6. Restore the electric fire detec-tion system to a normal condition inaccordance with the manufacturer’sinstructions after the system air pres-sure has automatically been restoredto normal.

Step 7. Close the System Shut-offValve (Fig. 1).

Step 8. Open the Main Control Valve(Fig. 1) one turn beyond the position atwhich water just begins to flow fromthe Main Drain Valve (Fig. 2B).

Step 9. Close the Main Drain Valve.

Step 10. Close the Air Supply ControlValve.

Step 11. Manually operate Zone 1 ofthe Releasing Panel, and then operateZone 2 of the Releasing Panel by par-

tially opening the System Main DrainValve (Fig. 2B) to relieve air pressureat the Low Pressure Alarm Switch, andverify the following:

• Verify that the DV-5 Deluge Valveoperates, as is indicated by a dis-charge of water from the SystemMain Drain 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 auto-matic system operation upon bothelectric detection and loss of systemair pressure.

Step 12. Reset the Double InterlockDry System in accordance with theSystem Setting Procedure section.

Quarterly Waterflow Alarm TestProcedureTesting of the system waterflowalarms must be performed quarterly.To test the waterflow alarm, open theAlarm Test Valve, which will allow aflow of water to the Waterflow Pres-sure Alarm Switch and/or Water MotorAlarm. Upon satisfactory completionof the test, close the Alarm Test Valve.
