1. DEsCrIPTIoNThe 4” Model G-4000P Electric Release Preaction System Riser Assembly can be used as a Single Interlock Preaction System with Electric Release, or as a Double Interlock Preaction System with Electric/Pneu-Lectric Release. These �reaction systems are commonly usedThese �reaction systems are commonly used where it is im�ortant to control accidental water discharge due to inadvertent damage to the s�rinkler �i�ing. The small �ro�ile, lightweight, �ilot o�erated �iking G-4000P �alve comesThe small �ro�ile, lightweight, �ilot o�erated �iking G-4000P �alve comes com�lete as shown in Figure 8. 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.A. Viking supervised single-Interlocked Electric release Preaction systems Utilizing the Viking G-4000P Valve

The system �i�ing is �ressurized with air or nitrogen as required by NFPA 13 �or su-�ervisory �ur�oses only. �iking recommends a minimum o� 15 to 20 �si (1.0 to 1.4 bar) �or su�ervisory air �ressure �or single interlock systems (re�er to Table 2 �or double interlock systems). This �eature serves to �revent undetected leaks on the system �i�-ing network. I� the system �i�ing or a s�rinkler is damaged, the su�ervisory �ressure is reduced and a “low air” su�ervisory alarm is activated. Electrically released �reaction systems require a 24 �DC normally closed electric so-lenoid valve controlled by an a��roved release control �anel with com�atible detection system. In �ire conditions, when the detection system o�erates, the system control �anel energizes the solenoid valve o�en. When the solenoid o�ens, the �riming water is relieved �rom the internal �rime chamber assembly. The �rime chamber assembly colla�ses, and water �asses through the G-4000P �alve and internal check dia�hragm to the system �i�ing network. The entire s�rinkler system �ills with water. The s�rinkler �i�ing will remain �illed with water until a s�rinkler o�erates.

B. Viking supervised Double-Interlocked Electric/Pneu-Lectric release Preaction systems Utilizing the Viking Model G-4000P Valve.

The system �i�ing is �ressurized with air or nitrogen to serve both as a means o� su�ervising the integrity o� the �i�ing network and as one �ortion o� the system release o�eration. This �eature serves to �revent undetected leaks on the system �i�ing net-work. I� the system �i�ing or a s�rinkler is damaged, the su�ervisory �ressure is reduced and a “low air” su�ervisory alarm is activated. The 24 �DC normally closed electric solenoid and an additional “low air” alarm switch are connected to a com�atible release24 �DC normally closed electric solenoid and an additional “low air” alarm switch are connected to a com�atible releaseelectric solenoid and an additional “low air” alarm switch are connected to a com�atible release control �anel and com�atible detection devices. The release control �anel is �rogrammed so that a signal �rom both a release device and the low air alarm switch must be received be�ore the solenoid is allowed to o�en. The air �ressure switch has two inde�endently o�erating connections. The high side is wired as a low air su�ervisory switch, and the low side is wired as low air alarm. In �ire conditions, a detection device and the low air alarm switch must o�erate in order to o�en the solenoid valve. When the solenoid o�ens, �riming water is relieved �rom the G-4000P �alve’s internal �rime chamber assembly. The �rime chamber assembly is �orced o�en by the system water su��ly and water �asses through the G-4000P valve and internal check dia�hragm to the system �i�ing network. The entire s�rinkler system �ills with water.

4. INsTALLATIoN:A. General Installation Instructions

1. For �ro�er o�eration and a��roval, the valve must be installed in the vertical �osition as trimmed �rom the �actory. DO NOT modi�y the �actory assembled trim exce�t as described in this technical data sheet.

2. A 12” section o� �i�e is �rovided with the G-4000P Electric Release Preaction System Riser Assembly. Prior to valve mainte-nance, this section o� �i�e may be removed to �rovide clearance �or li�ting the cover �rom the body.

3. The Model G-4000P �alve must be installed in an area not subject to �reezing tem�eratures or �hysical damage. I� required, �rovide a valve house (enclosure) with adequate heat around the valve and trim. Freezing tem�eratures will damage the G-4000P valve. When corrosive atmos�heres and/or contaminated water su��lies are �resent, it is the owner’s res�onsibility to veri�y com�atibility with the Model G-4000P �alve and associated equi�ment.

4. The �iking Model E-1 Accelerator should be installed at the location indicated in Figure 1 when required. Note: The accelerator would only be used �or Double Interlock Systems.

B. Air supply Design1. Air Com�ressor Size

�iking recommends a minimum o� 15 to 20 PSI (1.0 to 1.4 bar) o� su�ervisory �ressure be established within the �i�ing network �or single interlock systems (re�er to Table 2 �or double interlock systems). While lower �ressures are allowed by NFPA 13 �or single interlock �reaction systems, maintaining higher air �ressure within the system will assist maintenance �ersonnel in �inding and isolating inadvertent or accidental leaks within the system quickly.NFPA 13 requires that the air su��ly be ca�able o� �illing the entire s�rinkler system to its required air �ressure within 30 minutes. A common method o� sizing an air com�ressor is to use the �ollowing �ormula:

where:� = �olumeP = Required Air PressureT = Fill time (ty�ically 30 min.)7.48 = gal. / �t.314.7 = atmos�heric �ressure

Example:System volume as determined by table 1 = 750 gallonsRequired Air �ressure = 20 �si (Single Interlock System)Com�ressor

Size (c�m) = � x P

7.48 x 14.7 x T

There�ore, the com�ressor shall be ca�able o� �roviding 5 c�m.

NoTE: �iking recommends tank-mounted air com�ressors �or Double Interlock Electric/Pneu-Lectric Release Preaction Systems.2. Nitrogen Cylinder Gas Su��ly (See Figure 1.)

Nitrogen may be used in �lace o� air com�ressors. Nitrogen is su��lied in �ressurized cylinders in various sizes and �ressures. Some o� the most common are 122 Cu. Ft. at 1900 PSI (3455 L at 131 bar), 225 Cu. Ft. at 2100 PSI (6372 L at 145 bar), and 280 Cu. Ft. at 2300 PSI (7930 L at 159 bar). When nitrogen cylinders are used as a �rimary air su��ly, s�are cylinders should be �urnished and located at the valve location. To determine the a��roximate amount o� nitrogen to be �urnished, the �ollowing �ormula may be used:

S�ecial attention must be given to systems em�loying a bottled-gas su��ly. Because only a limited amount o� gas is available, small leaks that normally would go unnoticed in systems being su��lied by mechanical com�ressors, can become critical to the system’s overall �er�ormance. I� the system is to �unction at tem�eratures as low as -40 °F (-40 °C), and, i� bottled nitrogen is the gas su��ly, the system is �articularly susce�tible to leakage, and s�ecial care should be taken to ensure against leaks throughout the entire system.

C. Air supply Installation1. Install the required air su��ly as described in section 4.B. The size o� the com�ressor and amount o� air required should be de-

termined in accordance with Tables 1 - 3. The air or nitrogen su��ly to the �reaction system must be clean, dry, and oil �ree.2. Automatic air su��lies must be regulated, restricted, and �rom a continuous source. A �iking air maintenance device should

be installed on each system equi��ed with a tank-mounted com�ressor, �lant air, or nitrogen. For com�ressors with a ca-�acity less than 5.5 �t3/min at 10 �sig (0.154 m(0.154 m3/min at 0.69 bar), NFPA 13 does not require an air maintenance device. In NFPA 13 does not require an air maintenance device. In addition, an air maintenance device should not be used with riser mounted com�ressors as this can lead to com�ressor “short cycling”. �iking recommends using a tank-mounted com�ressor with air maintenance device. This can become critical whenThis can become critical when accelerators are installed on the system.

D. Pressure switch wiring;Wire the Alarm Pressure Switch (PS10) and Air Su�ervisory Switch (PS40), and adjust �ressure settings as shown in Figures 2 - 4.
