DOUBLE INTERLOCK PREACTION

WITH ELECTRIC/PNEUMATIC RELEASE

1. DESCRIPTION

Viking supervised Double-Interlocked Electric/Pneumatic Release Preaction Systems
utilize the Viking G-4000P Valve.

The small prole, lightweight, pilot operated Viking Model G-4000P Valve comes complete
as shown in Figure 8. The system piping is pressurized with air or nitrogen to serve both as
a means of supervising the integrity of the piping network and as one portion of the system
release operation. This feature serves to prevent undetected leaks on the system piping
network. If the system piping or a sprinkler is damaged, the supervisory pressure is reduced
and a “low air” supervisory alarm is activated.

This pilot-operated externally reset valve also includes an internal check diaphragm,
which eliminates the need for a separate check valve being installed in the system riser.

Double interlocked electric / pneumatic release preaction systems require the use of one 24
VDC normally closed (NC) electric solenoid and one pneumatic actuator. The electric sole­noid is connected to a compatible release control panel and compatible detection devices.
The pneumatic actuator is controlled by the air pressure that is contained within the sprinkler
system piping. In re conditions, both the solenoid and a sprinkler must open in order for the
Preaction valve to operate. When both the solenoid and pneumatic actuator open, the prim­ing water is relieved from the internal prime chamber assembly. The prime chamber assem­bly collapses, and water passes through the G-4000P Valve and internal check diaphragm
to the system piping network. The entire sprinkler system lls with water.
Double interlock electric/pneumatic release preaction systems are commonly used in cold
storage applications and other areas where it is important to control accidental water dis­charge due to inadvertent damage to the sprinkler piping.

contaminated water supplies are present, it is the owner’s responsibility to verify compatibility with the Model G-4000P Valve
and associated equipment.

4. The Viking E-1 Accelerator should be installed at the location indicated in Figure 1 when required.

B. Air Supply Design

1. Air Compressor Size
Viking recommends tank mounted air compressors for Double Interlock Electric/Pneumatic Release Preaction Systems. The pneu­matic actuator requires at least 30 psi (2.1 bar) of air pressure be established within the piping network for systems with water pressure
up to 175 psi (12.1 bar) and 50 psi (3.45 bar) of air pressure for systems with water pressures up to 250 psi (17.2 bar).

NFPA 13 requires the air supply to be capable of lling the entire sprinkler system to its required air pressure within 30 minutes. A
common method of sizing an air compressor is to use the following formula:

Compressor
Size (cfm) =

V x P

7.48 x 14.7 x T

Therefore, the compressor shall be capable of providing 7 cfm.

2. Nitrogen Cylinder Gas Supply (See Figure 1)
Nitrogen may be used in place of air compressors. Nitrogen is supplied in pressurized cylinders in various sizes and pressures. Some
of the most common are 122 Cu. Ft. at 1,900 PSI (3,455 Ltrs. at 131 bar), 225 Cu. Ft. at 2,100 PSI (6,372 Ltrs. at 145 bar), and 280
Cu. Ft. at 2,300 PSI (7,930 Ltrs. at 159 bar).
When nitrogen cylinders are used as a primary air supply, spare cylinders should be furnished and located at the valve location.
To determine the approximate amount of nitrogen to be furnished, the following formula may be used:

Where:

Vc= Volume of Cylinder (ft3)
P = Required Nitrogen Pressure (psig)

Vc =

Figure 2 - Alarm Pressure Switch Wiring

(Alarm Pressure Switch should be set to 5 psi)

FIELD ADJUSTMENTS:
Alarm Pressure Switch: The operating point of the switch can be

adjusted to any point between 4 PSI (0.27 bar) and 8 PSI (0.55 bar)
by turning the adjustment knob(s) clockwise to raise the actuation
point or counter-clockwise to lower the actuation point.

Air Supervisory Switch: The operating point of the switches can
be adjusted to any point between 10 PSI (0.7 bar) and 60 PSI
(4.1 bar) by turning the adjustment knob(s) clockwise to raise the
actuation point or counter-clockwise to lower the actuation point.
The high and low switches are adjusted independently.

Figure 3 - Air Supervisory Switch Wiring

Special attention must be given to systems employing a bottled-gas supply. Because only a limited amount of gas is available, small
leaks which normally would go unnoticed in systems being supplied by mechanical compressors, can become critical to the system’s
overall performance. If the system is to function at temperatures as low as -40 °F (-40 °C), and, if bottled nitrogen is the gas supply, the
system is particularly susceptible to leakage, and special care should be taken to ensure against leaks throughout the entire system.

C. Air Supply Installation

1. Install the required air supply as described in section 4.B. The size of the compressor and amount of air required should be
determined in accordance with Tables 1, 2 & 3. The air or nitrogen supply to the Preaction System must be clean, dry, and
oil free.

2. Automatic air supplies must be regulated, restricted, and from a continuous source. A Viking Air Maintenance Device should
be installed on each system equipped with a tank mounted compressor, plant air or nitrogen. For compressors with a capacity
less than 5.5 ft3/min at 10 psig (0.154 m3/min at 0.69 bar), NFPA 13 does not require an air maintenance device. The use of
an air maintenance device with riser mounted compressors can lead to compressor “short cycling”. Viking always recom­mends that a tank mounted compressor with air maintenance device be used. This can become critical when accelerators
are installed on the system.

D. Pressure Switch Wiring;

Wire the Alarm Pressure Switch (PS10) and Air Supervisory Switch (PS40), and adjust pressure settings as shown in Figures 2 - 4.

E. Hydrostatic Test:

The Preaction System, including Sprinkler Piping and Sprinklers shall be hydrostatically tested at 200 psi (13.79 bar) and maintained
for 2 hours, in accordance with NFPA 13. Systems normally subjected to working system pressures in excess of 150 psi (10.34 bar)
shall be tested at a pressure of 50 psi (3.45 bar) in excess of system working pressure.
F. Placing the Valve in Service: (Refer to Figure 5)
When the Preaction System is ready to be placed in service, verify that the pneumatic release system is in a normal condition and
that the electric release system has been reset.

1. Verify that the water supply main control valve supplying the G-4000P Valve is closed.

2. Close the prime valve.

3. Open the main drain valve.

4. Open the flow test valve.

5. Drain all water from the Preaction System. If the system has operated, or if water has entered the system, allow enough time
to completely drain the system.

6. Close the main drain valve.

7. Open the priming valve. Prime water pressure will enter and expand the valve’s internal diaphragm assembly onto the valve
seat, effectively closing the valve. Verify prime pressure has been established on the prime pressure gauge.

8. Establish air pressure on the system.

9. Verify that no water flows from the drip check when the plunger is pushed.

10. When the priming pressure has been verified as being established, slowly open the water supply control valve.

11. When flow is developed from the flow test valve, CLOSE the flow test valve.

12. Fully open the water supply main control valve.

13. Secure all valves in their normal operating position.

14. Reset the Release Control Panel.

15. Notify Authorities Having Jurisdiction and those in the affected area that the system is in service.

16. The system is now fully operational.

G. Operational Test:

An operational test shall be performed on the system in accordance with NFPA 13. Refer to Section 6 for Inspection and Operation
Test Procedures.

5. OPERATION

A. In the Set position:

When air pressure is introduced into the sprinkler piping, the sensing end of the pneumatic actuator is pressurized. This closes
the pneumatic actuator. The closed pneumatic actuator, and the normally closed solenoid valve prevent prime water from escap­ing the prime chamber of the G-4000P Valve. When prime water enters the prime chamber, the rolling diaphragm is pressurized,
causing it to expand downward onto the water seat.

B. Fire Condition:

When the detection system operates, the normally closed solenoid valve is powered open. At this point, the prime water is still held
in the prime chamber by the closed pneumatic actuator. When a sprinkler operates, air pressure is lost on the sensing end of the
pneumatic actuator, causing the pneumatic actuator to open. With both the pneumatic actuator and solenoid valve open, prime
water is drained from the prime chamber, causing the G-4000P Valve to open, lling the sprinkler piping with water. Water from
the intermediate chamber of the G-4000P Valve pressurizes the sensing end of the PORV causing the PORV to open. The open
PORV prevents water pressure from building in the prime chamber should the solenoid or pneumatic actuator close.

6. INSPECTION AND OPERATIONAL TEST

NOTICE: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM AND DEVICES IN PROPER
OPERATING CONDITION. It is imperative that the system be inspected and tested on a regular basis in accordance with NFPA 25.

The frequency of the inspections may vary due to contaminated water supplies, corrosive water supplies, corrosive atmospheres, as
well as the condition of the air supply to the system. For minimum maintenance and inspection requirements, refer to NFPA 25. In ad­dition, the Authority Having Jurisdiction may have additional maintenance, testing, and inspection requirements that must be followed.
Viking does not require internal inspection of the valve as part of routine inspection and testing. Internal maintenance is generally only
required for valve repairs and internal component replacement.

WARNING: Any system maintenance that involves placing a control valve or detection system out of service may eliminate the re
protection capabilities of that system. Prior to proceeding, notify all Authorities Having Jurisdiction. Consideration should be given to
employment of a re patrol in the affected areas.
A. Low Air Pressure Alarm Test: (Refer to Figure 5.)
Quarterly testing of low air alarms is recommended.

To Test Sprinkler System “Low Supervisory Air” Alarm:

1. To prevent operation of the G-4000P Valve and filling the system with water during the test, DO NOT operate the electric
detection system during test. Consider closing the main water supply control valve.

2. Fully open the sprinkler system test connection.

3. Verify that low air alarms operate within an acceptable time period and continue without interruption.

4. Close the test connection.

5. Establish recommended pneumatic supervisory pressure to be maintained. Refer to section 4. INSTALLATION.

6. Reset the system release control panel. Alarms should stop.

When testing is complete, return the system to service following steps 1 through 8 below.

B. Full Flow Trip Test: (Refer to Figure 5)

Performance of a trip test is recommended annually during warm weather. Consider coordinating this test with operation testing
of the detectors.

CAUTION! PERFORMANCE OF THIS TEST WILL CAUSE THE G-4000P VALVE TO OPEN AND THE SPRINKLER SYSTEM TO
FILL WITH WATER.

To Trip Test the Electric / Pneumatic Double-Interlock Preaction System:

1. Notify the Authority Having Jurisdiction and those in the area affected by the test.

2. Trip the G-4000P Valve by performing option “a” or “b” below.

a. Operate the electric release control system according to the manufacturer’s instructions, and open the sprinkler system

test connection.

b. Operate the emergency release Valve .

3. The G-4000P Valve should open, filling the sprinkler system with water. Water flow alarms should operate.

4. Verify that there is adequate flow from the sprinkler system test valve.

When Trip Testing is complete:

5. Perform steps 1 through 13 of section 4.F. PLACING THE SYSTEM IN SERVICE to return the system to service.

6. Notify the Authority Having Jurisdiction and those in the affected area that testing is complete.

7. MAINTENANCE

Viking does not require an internal inspection of the G-4000P Valve unless there is an indication of damage to internal components.
