GeneralThe "Automatic" Model F Deluge Valve is a waterflow con-trol/alarm device designed for installation in the main sup-ply to a deluge system of sprinklers or nozzles. Its pur-pose is twofold.

First, the valve holds back the water, keeping it from flow-ing into the system until such time that the detection sys-tem operates (see Description/ Operation).

Second, the valve provides the means to actuate a firealarm when water flows into the system. The alarm maybe accomplished in two ways: (1) Mechanically by meansof water flow to a water motor alarm and/or (2) electricallyvia a water-pressure-actuated alarm switch (circuit closer)connected to an electrically operated signaling device suchas a bell or light.

The Model F Deluge Valve is made in three sizes: 2-1/2"(63.5 mm), 4" (101.6 mm) and 6" (152.4 mm). Each valveis provided with a basic trim package that includes watersupply connections for wet pilot line actuation, manualcontrol connections, drain connections, alarm outlets andan alarm test by-pass. Optional trim packages are avail-able to provide connections for dry pilot line and electricaloperation. Alarm and supervisory devices may be providedseparately.

Note: The Model F Deluge Valve is designed for use withwater. If it is to be used as a companion valve to controlfoam concentrate for a foam/water system, the valve andthe diaphragm actuator must be thoroughly flushed and

regularly inspected (see Maintenance on page 12).

ApprovalsModel F Deluge Valves are listed or approved by various

testing and inspection organizations concerned with prod-

uct evaluation. These include:

• Underwriters Laboratories (UL)

• Factory Mutual (FM)

• Underwriters Laboratories of Canada (ULC)

The valves are listed/approved with specific trim and for

installation in accordance with the applicable requirements

of NFPA 13. Therefore, no substitutions or omissions, in

part or in full, are allowed.

All devices are listed/approved for a maximum water work-

ing pressure (WWP) of 175 psi (1206.6 kPa or 12.1 bar).

Description / OperationThe Model F Deluge Valve depends on water pressureacting on a diaphragm actuator to keep the clapper closedagainst the main water supply pressure. The valve oper-ates when the pressure in the diaphragm actuator is re-lieved.

In the set position (see Figure 1 on page 2), the clapper isheld closed by the latch. And the latch, in turn, is held inplace by force applied to it by a push rod in the diaphragmactuator.

Water pressure to the diaphragm actuator is maintainedthrough connections to the main water supply taken up-stream of the System Control Valve. These connectionsalso supply water pressure to a wet pilot line of sprinklers,or to a dry pilot actuator or electric solenoid valve, depend-ing on the type of detection system used.

When fire opens a pilot sprinkler or operates an electricaldetector, water pressure in the pilot line is relieved. Thiscauses a loss of pressure in the diaphragm actuator. Andwithout pressure acting on the diaphragm, the push rodcannot hold the clapper latch in place. The main watersupply pressure then forces the clapper open. Water flowsthrough the deluge valve into the system piping and throughthe alarm line connections to sound the water motor alarmand/or operate the pressure-actuated alarm switch (seeFigure 2 on page 2).

Operation of the manual control station at the deluge valvealso relieves the water pressure in the pilot line and oper-ates the valve. The water working pressure range of theModel F Deluge Valve is 20 psi to 175 psi.

Upon completion of each Model F Deluge Valve installa-tion, a partial flow or full flow test is to be conducted. Recordthe system water pressure and the diaphragm actuatoroperating pressure. See page 23 for chart.

"Automatic" Model F Deluge Valves - Wet Pilot Actuation

GeneralThe basic trim setup for the "Automatic" Model F Deluge

Valve is for wet pilot actuation. The basic detection sys-

tem, therefore, is the wet pilot line of sprinklers. This sys-

tem consists of standard automatic fixed-temperature sprin-

klers (1/2" orifice x 1/2" NPT) spaced throughout the pro-

tected area and connected to the deluge valve by means

of pilot line piping either 1/2" or 3/4" in size, depending on

the requirements for the particular installation. Water pres-

sure is maintained in the pilot line through a restricted con-

nection from the main water supply which is taken upstream

of the System Control Valve.

When a sprinkler operates, the flow through the open sprin-

kler is at a rate greater than that which can pass through

the orifice restriction in the water supply connections. This

causes a drop in the pilot line pressure. And with this drop

in pressure, the diaphragm actuator can no longer hold

the clapper latch in place. The deluge valve operates and

water flows into the system (see Description/Operation).

Operation of the manual control station at the deluge valve

also relieves the water pressure in the pilot line and oper-

ates the valve.

Note: Wet pilot lines are not to be installed in areas

subject to freezing temperatures.

InstallationWet pilot lines for 2-1/2", 4" and 6" Model F Deluge Valves

are to be installed within the limitations shown on Graphs

A, B and C on page 12.

The curves on each graph show the maximum length of

1/2" pilot piping that may be provided with the deluge valve

in relation to the height of the pilot line above the valve

and the water supply pressure at the valve. The limitations

are shown for pressures up to 175 psi, the maximum wa-

ter working pressure of the Model F Deluge Valves.

The length/height/pressure relationship of the pilot line,

pilot sprinkler and water supply is one of hydraulics. The

curves on Graph A, B and C are based on a 1/2" pilot line.

If the size of the line is increased to 3/4", the lengths shown

on each graph may be increased by a factor of 4.

Example: Including a rise of 50 ft., the distance from the

most remote 1/2" orifice pilot sprinkler back to the 2-1/2"

deluge valve is 350 ft. The water supply pressure at the

valve is 100 psi. The designer must determine if an instal-

lation with a 1/2" wet pilot line is within the length/height/

pressure limitations set for the valve.

Referring to the 350 ft. curve on Graph A, the designer

finds that the height limitation is approximately 30 ft. for a

100 psi supply pressure. Since the pilot sprinklers must

be at an elevation of 50 ft., it is obvious that a 1/2" pilot

line cannot be used. The designer must now determine if

a 3/4" pilot line will be satisfactory.

On Graph A, moving up the vertical line at 100 psi until it

intersects with the horizontal one for 50 ft., the designer

finds the point to be between two curves. Interpolating, he

determines that for this height and pressure a 1/2" pilot

line may have a length of approximately 235 ft. It is obvi-

ous, then, that a 3/4" pilot line can be used, since multiply-

ing the 235 ft. length by the factor of 4 gives a value well

above the 350 ft. length involved. In other words, an in-

stallation can be provided with 3/4" pilot line piping up to

940 ft. long when the pilot sprinklers are located at a height

50 ft. above the deluge valve.

PipingPilot line pipe may be 1/2" (or 3/4") steel or copper. If steel

pipe is used, it must be galvanized.

Fittings used with steel pipe may be cast iron or malleable

iron. Fittings need to be galvanized only when required

because of external conditions.

GeneralAn optional actuation setup for the "Automatic" Model FDeluge Valve is for dry pilot actuation. With this setup, thedetection system is the dry pilot line of sprinklers.

Suitable for installation in areas subject to freezing tem-peratures, the dry pilot detection system consists of stan-dard automatic fixed-temperature sprinklers (1/2" orifice x1/2" NPT) spaced throughout the protected area and con-nected to a dry pilot actuator at the deluge valve by meansof 1/2" pilot line piping. The system is pressurized witheither compressed air or nitrogen.

When a sprinkler operates, the air or nitrogen pressure inthe pilot line is released. This relieves the pressure on thedry pilot actuator, allowing it to open and relieve the waterpressure in connections at the deluge valve.

Water pressure to the dry pilot actuator and on the dia-phragm actuator is maintained through a restricted con-nection from the main water supply. When the dry pilotactuator opens, the flow to drain is at a rate greater thanthat which can pass through the orifice restriction. Thiscauses a drop in the water pressure and with this drop inpressure, the diaphragm actuator can no longer hold theclapper latch in place. The deluge valve operates and waterflows into the system (see Description/Operation).

Operation of the manual control station at the deluge valvealso relieves the water pressure and operates the valve.

Graph D shows the air pressure (or nitrogen pressure) tobe maintained in the dry pilot line for water pressures upto 175 psi (see upper curve). The graph also shows the airpressure at which the dry pilot actuator operates in rela-tion to the water supply pressure (see lower curve). Thedifference between the two curves indicates the pressuredrop required for operation of the actuator.

Graph D: Dry Pilot Actuator Pressure Curves

Example: The water supply pressure at the deluge valveis 100 psi. The designer must determine the pilot line pres-sure to be maintained. Referring to the upper curve onGraph D, the designer finds that a pilot line pressure ofapproximately 31 psi is required for a water supply pres-sure of 100 psi. He also notes that the dry pilot actuator

"Automatic" Model F Deluge Valves - Dry Pilot Actuation

will operate when the pilot line pressure reaches 15 psi (a

drop of approximately 16 psi).

InstallationThe dry pilot detection system for the Model F Deluge Valveis very similar to the piping in a dry pipe system in that itconsists of lines of sprinklers containing air under pres-sure. It should be installed and tested, therefore, in a man-ner similar to that required for a dry pipe system (see NFPA13).

There are two trim options for dry pilot actuation - one forowner’s air supply and another for supply from nitrogencylinders.

The trim option for owner’s air is based on the supply be-ing from a reliable source. If any other device or equip-ment is required (a drum drip or air tank, for example) itmust be provided separately. The trim option setup doesinclude an outlet for a safety valve which may be orderedas an optional item.

The trim option for nitrogen supply does not include thenitrogen cylinders. These must be provided separately.Fasteners to secure them to the building structure can beordered as optional items.

For air or nitrogen pressures to be maintained in the drypilot line for various water supply pressures (up to 175

psi), refer to Graph D.

PipingPilot line pipe may be 1/2" steel or copper. If steel pipe isused, it must be galvanized.

Fittings used with steel pipe may be cast iron or malleableiron. Fittings need to be galvanized only when required

because of external conditions.

Optional AlarmsA pressure switch may be added to the dry pilot detectionsystem to (1) sound a trouble alarm on loss of air or nitro-gen pressure from the system and/or (2) to sound a firealarm when there is a substantial loss of system pressure,as when a pilot sprinkler operates. An outlet for the op-tional switch is provided in each trim option for dry pilotactuation.

For technical data on "Automatic" pressure switches, seeElectric Alarm Devices data sheet.

Trouble Alarm. The pressure switch used to signal low airpressure is to be set to indicate trouble (e.g., sound atrouble horn) on a loss of 6 psi in pilot line pressure.

Fire Alarm. The pressure switch used to signal operationof a pilot sprinkler is to be set to actuate a fire alarm (e.g.sound a bell) on a loss of 15 psi in pilot line pressure.

"Automatic" Model F Deluge Valves - Electric Actuation

GeneralAn optional actuation setup for the "Automatic" Model F

Deluge Valve is electric actuation. With this setup, the

detection system is an electric fire detection system.

Water pressure to the electric solenoid valve and on the

diaphragm actuator is maintained through a restricted con-

nection from the main water supply. When the electric so-

lenoid valve opens, due to a signal from an electric control

panel, the flow to drain is at a rate greater than that which

can pass through the orifice restriction. This causes a drop

in the water pressure at the diaphragm actuator and with

this drop in pressure, the diaphragm actuator can no longer

hold the clapper latch in place. The deluge valve operates

and water flows into the system (see Description/Opera-

tion).

Operation of the manual control station at the deluge valve

also relieves the water pressure and trips the valve.

InstallationThe electric solenoid valve is installed into the basic del-

uge trim as shown in the illustration below.

NFPA 25, Recommended Practice for the Inspection, Test-

ing and Maintenance of Sprinkler Systems.

TestingBefore proceeding with any tests involving water flow, cer-

tain precautions need to be taken.

1. Check the location where the test connection dis-

charges to make sure that all is clear and that there is

no possibility of the water flow causing damage or in-

jury.

2. Check the end of the test connection to make sure

that it is unobstructed. To obtain a satisfactory test,

there must be an unrestricted flow of water when the

test valve is wide open.

3. Check for alarm connections to a central station or

fire department. If such connections are found, give

proper notice to the signal receiving station before pro-

ceeding with the test.

Testing Waterflow Alarm Devices

NFPA 25 recommends that the waterflow alarm devices

be tested quarterly.

For a system using the Model F Deluge Valve, the primary

way to test these devices is by first closing the Alarm Con-

trol Valve, then opening the Alarm Test Valve. These two

valves, provided as part of the deluge valve trim, must be

operated in this sequence to keep water from entering the

system. The waterflow devices can be tested without op-

erating the system, since the water supply for the alarm

test line is taken from a point below the deluge valve clap-

per (see Description/Operation).

A test of the waterflow devices may also be obtained when

a full flow test is performed (see Test - Full Flow).

Caution: If alarms connect to a central station or fire de-

partment, notify the signal receiving station when all tests

have been completed.

Flow Test at Main Drain Valve (Main Drain Test)

NFPA 25 recommends that a water flow test be made quar-

terly from the main drain valve at the system riser. The

purpose of this test is to show whether or not the normal

water supply is available to the system. By comparing static

and residual pressure readings with those previously es-

tablished, a main drain test can indicate the presence of

closed valves or other obstruction in the supply piping.

The procedure for conducting a Main Drain Test is as fol-

lows:

Testing and Maintenance

1. With the Main Drain Valve closed, note and record

the reading on the Water Pressure Gage at the Del-

uge Valve.

2. Open the Main Drain Valve slowly until it is wide open.

Then, check to make sure that a full steady flow of

water is discharging from the main drain pipe.

Note: If a full steady stream is not discharging,

check the main drain piping further for possible

obstructions.

3. Allow the water to flow until the reading on the Water

Pressure Gage drops and stabilizes. Then, record this

reading.

Note: The first and higher pressure reading is the

static pressure. The second, lower reading is the

residual pressure with a given flow discharging from

the main drain pipe.

4. Close the Main Drain Valve slowly.

Caution: If alarms have been temporarily shut off,

they must be returned to service. If alarms con-

nected to a central station or fire department, notify

the signal receiving station when the test has been

completed.

5. Compare both readings with previously recorded or

normal readings.

Note: If the readings compare favorably, the water

supply may be considered satisfactory. If, however,

the pressure readings vary to any great extent, the

condition should be investigated to determine the

cause. Some possible causes are:

• Partially or totally closed system control valves.

• Clogged or frozen water mains.

• Serious leakage at valves or mains.

Testing of Deluge Valve

NFPA 25 recommends that the deluge valve be inspected

and tested at least annually. It is recommended that the

deluge valve be inspected and tested on a quarterly, semi-

annual, or annual basis depending on the ambient condi-

tions present at the valve installation. More frequent in-

spection and testing may be required if the water supply

or ambient conditions are unusually corrosive, or of such

a nature to have an adverse effect on the operation of the

valve or fire protection system. If the valve is used as a

foam or companion valve, the valve should be tested at

least quarterly.

SVL400 19

The usual procedure is to operate the deluge valve with-

out permitting a full flow of water into the system. But peri-

odically, as recommended by the Authority Having Juris-

diction, a full flow test should be provided to check the

complete function of the system. These two test proce-

dures are designated, respectively, as Test-Partial Flow

and Test-Full Flow.

Note: Deluge valves should be tested during warm

weather.

Note: Before proceeding with any test of a deluge valve,

the water supply line to the system should be thoroughly

flushed. The system main drain may be used for this pur-

pose; however, if there is a hydrant on the supply line, it

should be used to flush the piping before the main drain is

opened.

Caution: If the deluge valve is used as a foam companion

valve, the deluge valve must be thoroughly flushed with

water immediately after any foam concentrate or foam/wa-

ter mixture gets into the valve body to prevent corrosive

deposit buildup. Failure to do so may result in an inopera-

tive valve.

Test-Partial Flow. The procedure for testing the deluge

valve without a full flow of water is as follows:

1. Open the Main Drain Valve slowly until it is wide open.

Then check to make sure that a steady full flow of

water is discharging from the main drain pipe.

2. Allow the water to flow at full pressure long enough to

clear the water of any accumulation of scale or for-

eign material.

3. Slowly close the Main Drain Valve.

4. Close the System Control Valve, then open it just

slightly until there is enough pressure to raise the clap-

per to a stopped position when the valve is operated.

The deluge valve is now ready for testing.

5. At the Manual Control Station, pull the handle to open

the enclosing box, then, while watching the diaphragm

actuator pressure gage, slowly pull the interior oper-

ating lever down. Water should discharge from the

drain tubing to relieve the pressure in the diaphragm

actuator line and operate the deluge valve.

Note: The deluge valve may also be tested by

opening the test valve on the pilot line to simulate the

operation of a pilot sprinkler or by applying heat to an

electrical detector.

6. When the deluge valve operates, note the pressure

reading for the diaphragm actuator and quickly close

the System Control Valve and open the Main Drain

Valve.

7. Record the system water pressure and the diaphragm

actuator pressure at the time the valve operates. Com-

pare this data with initial installation test records.

Note: If the diaphragm actuator operating pressure

exceeds plus or minus 20% of the operating pres-

sure recorded at the time the valve was installed, the

cause should be determined and the condition cor-

rected (see Maintenance).

8. Thoroughly clean the Deluge Valve and Diaphragm

Actuator, renew parts as required and reset the valve

(see Resetting of System).

Test-Full Flow. After making the necessary arrangements

and taking the necessary precautions to discharge water

in the protected area, a full flow test of the system may be

conducted as follows:

1. Open the Main Drain Valve until it is wide open. Then

check to make sure that a steady full flow of water is

discharging from the main drain pipe.

2. Allow the water to flow at full pressure long enough to

clear the water of any scale or foreign material.

3. Slowly close the Main Drain Valve.

4. At the Manual Control Station, pull the handle to open

the enclosing box, then, while watching the diaphragm

actuator pressure gage, slowly pull the interior oper-

ating lever down. Water should discharge from the

drain tubing to relieve the pressure in the diaphragm

actuator line and operate the deluge valve.

Note: The deluge valve may also be tested by

opening the test valve on the pilot line to simulate the

operation of a pilot sprinkler or by applying heat to an

electrical detector.

5. Record the system water pressure and the diaphragm

actuator pressure at the time the valve operated. Com-

pare this data with initial installation test records.

Note: If the diaphragm actuator operating pressure

exceeds plus or minus 20% of the operating pres-

sure recorded at the time the valve was installed, the

cause should be determined and the condition cor-

rected (see Maintenance).

6. After the deluge valve operates, allow the water to flow

into the system and discharge at the sprinklers or

nozzles. Then, check for proper coverage of the pro-

tected area.

7. When the flow test is complete, close the System Con-

trol Valve and open the Main Drain Valve.

8. After draining the system, thoroughly clean the Del-

uge Valve and Diaphragm Actuator, renew parts as

20 SVL400

required and reset the valve (see Resetting of Sys-

tem).

Testing of Foam Companion Valve

If the deluge valve is used as a foam companion valve,

the valve should be tested every three months.

The procedure for conducting a foam companion test is

as follows:

1. Close the System Control Valve.

2. Remove the hand hole cover.

3. Depressurize the diaphragm actuator by pulling the

lever on the Manual Control Station. See if the latch

moves as the pressure in the diaphragm actuator de-

creases to zero.

4. Manually lift the clapper. If the clapper cannot be manu-

ally lifted, thoroughly clean the valve. Any evidence of

foam concentrate or foam mixture should be flushed

out of the valve body with water.

Caution: If the deluge valve is used as a foam

companion valve, the deluge valve must be thor-

oughly flushed with water immediately after any

foam concentrate or foam/water mixture gets into

the valve body to prevent corrosive deposit buildup.

Failure to do so may result in an inoperative valve.

5. Reset valve (see Resetting of System).

Testing of Dry Pilot Actuation System

The dry pilot actuator, pressure switch and related equip-

ment should be tested and inspected at least annually.

The following procedure is recommended for testing the

dry pilot actuator and pressure switch:

1. Close the System Control Valve and open the Main

Drain Valve.

2. Close the Air (or Nitrogen) Supply Control Valve.

3. Check the operation of the Pressure Switch and Dry

Pilot Actuator by slowly opening the Inspectors Test

Valve to bleed the air (or nitrogen) from the actuation

system.

Note: The pressure switch should operate to sound

a trouble alarm when the dry pilot line pressure

drops by 6 psi. With continued loss of pressure, the

dry pilot actuator should operate and allow water to

discharge to drain.

Note: If the dry pilot actuator should fail to operate,

remove it from service and check for obstructions.

Clean the device and replace parts as necessary.

4. Close the Inspectors Test Valve and Pilot Line Ball

Valve.

5. Inspect the Pilot Line Strainer. If necessary, clean the

strainer.

6. Check all low points on the dry pilot line and drain any

accumulated condensate. Purge the line if any foreign

material is found.

7. To place the actuation system back in service, slowly

open the Air Supply Control Valve. Turn the valve to

full open when the pressure gage indicates a steady

pressure.

Note: Refer to the Dry Pilot Actuator Pressure Curves

for pilot line air pressure setting required for the

particular water supply pressure.

8. Slowly open the Pilot Line Ball Valve and restore wa-

ter pressure on the Diaphragm Actuator and Dry Pilot

Actuator. Then, remove the hand hole cover and check

to be sure that the Clapper latch is properly engaged

on the Deluge Valve Clapper.

Note: If the dry pilot actuator should fail to reset,

remove it from service and check it for obstructions.

Clean the device and replace parts as necessary.

9. Slowly open the System Control Valve. When water

starts to discharge from the main drain pipe, slowly

close the Main Drain Valve.

10. Seal, lock or otherwise secure the System Control

Valve in a full open position (per NFPA 25). The sys-

tem is now ready for service.

11. If alarms connect to a central station or fire depart-

ment, notify the central receiving station that the sys-

tem has been returned to service.

MaintenanceIt is recommended that the Model F Deluge Valve be in-spected and tested on a quarterly, semi-annual or annualbasis, depending on the ambient conditions present at thevalve installation. More frequent inspection and testing maybe required if the water supply or ambient conditions areunusually corrosive, or of such a nature as to have an ad-verse effect on the operation of the valve or fire protectionsystem. Several areas to be routinely inspected are:

Clapper/Clapper Latch. After each test, inspection, or be-fore resetting, inspect the clapper and latch mating sur-faces. These surfaces must be smooth. Inspect the sur-face on the end of the latch against which the shaft of thediaphragm actuator presses to hold the clapper closed.This surface must also be smooth. Refinish the clappernose and roller latch tail surface using No. 220 grit sand-paper followed by crocus cloth, to obtain a smooth finish.

Clean these surfaces with laquer thinner and allow the

surfaces to dry.

SVL400 21

Inspect the clapper facing, then install the clapper and latch

in the valve.

Diaphragm Actuator. The diaphragm actuator must be

kept free of all foreign matter that could impair its opera-

tion. After removing the diaphragm actuator from the valve

body, check that the piston stem of the diaphragm actua-

tor is free to move to both ends of its stroke. Flush out any

debris inside the diaphragm actuator. If repairs are needed

which cannot be accomplished in the field, the device

should be replaced.

Clapper Facing. The rubber clapper facing should be

checked for wear or damage, and to determine that it is

free of dirt and other foreign substances. If found to be

worn or damaged (e.g., foreign matter imbedded in the

surface), the facing should be replaced. If it is dirty, it should

be cleaned, but compounds which could damage the rub-

ber facing should never be used.

Seat Ring. The seat ring should be cleaned thoroughly

and checked for damage. If it is found to be damaged, the

complete valve assembly should be replaced.

Alarm LIne Strainer, Pilot Line Strainer & Air Supply

Strainer. The strainers in the alarm line, pilot line and air

supply should be checked and cleaned thoroughly.

Alarm Test Valve & Main Drain Valve. All controlling

valves normally closed when the deluge valve is in the set

position should be checked to be sure that they are fully

closed and not leaking.

System Control Valve, Alarm Control Valve, Pilot LIne

Ball Valve & Air (or Nitrogen) Supply Valve. All control-

ling valves normally open when the deluge valve is in the

set position should be checked to be sure that they are in

the fully open position and sealed, where required.

Dry Pilot Actuator. The dry pilot actuator must be kept

free of all foreign matter that could impair its operation. It

should be checked periodically for proper operation and

then cleaned as required. If repairs are needed that can-

not be accomplished in the field, the device should be re-

placed.

Electric Solenoid Valve. The electric solenoid valve

should be checked periodically for proper operation.

Deluge Valve and Trim. The overall setup should be

checked for visible leaks and physical damage to the valve

and connections (e.g., broken gages).

Caution: If the deluge valve is used as a foam companion

valve, the deluge valve and diaphragm actuator must be

thoroughly flushed with water immediately after any foam

concentrate or foam/water mixture gets into the valve body.

Failure to do so may result in an inoperative valve.

Resetting of System.

After operation, The "Automatic" Model F Deluge Valve

must be reset and the system restored to service as soon

as possible.

1. Close the System Control Valve (OS& Y, PIV or other).

Caution: In the event of a fire, the system control

valve is to be closed only after it has been deter-

mined that the fire has been extinguished.

2. Open the Main Drain Valve and allow the system to

drain completely. Leave the valve open.

3. Close the Ball Valve in the water supply to the pilot

line connections. If a dry pilot actuator is used, also

close the Air Supply Control Valve.

4. If the Deluge Valve operated automatically, restore the

actuation system to service.

Wet Pilot Actuation. Replace the sprinklers that op-

erated.
