1. DEsCrIpTIoN(Refer to Figures 1-3.)A Viking Non-Interlocked Preaction system utilizes a Viking Deluge Valve to control water flow into system piping equipped with closed sprinklers. Under normal operating conditions, the sprinkler piping is supervised with pressurized air or nitrogen to ensure against undetected leaks. Non-Interlocked Preaction �ystems are recommended �or very large dry systems that e�ceed the capacity normallyNon-Interlocked Preaction �ystems are recommended �or very large dry systems that e�ceed the capacity normally permitted on a dry valve. Pneumatically controlled preaction systems require a pneumatic release system, equipped with thermostaticPneumatically controlled preaction systems require a pneumatic release system, equipped with thermostatic (rate-o�-rise) releases, and/or fi�ed temperature releases, and/or pilot heads. Release trim �or pneumatically controlled preaction systems utilize a pneumatic actuator normally held closed by pressure maintained in the pneumatic release system AND pneumatic pressure maintained in the closed sprinkler system. Non-Interlocked Preaction �ystems are designed so the deluge valve will open when EITHER a detector on the pneumatic release system operates, OR a loss o� pressure in the sprinkler system occurs. When the deluge valve opens, water will flow into the sprinkler piping and out o� any open sprinklers and any other opening on the system. In the event o� non-operation o� the release system, the system will operate as a dry system. In the event o� damage to the sprinkler piping or a sprinkler, the deluge valve will open. Water will flow �rom any open sprinklers and any other opening in the sprinkler system piping.

The pneumaticand pneumatic actuator (F.1). The pneumatic(F.1). The pneumatic. The pneumatic actuator is held closed by pressure maintained in the pneumatic release system and pneumatic pressure maintained in the sprinkler system. The pressure in the priming chamber holds the deluge valve clapper closed, keeping the outlet chamber and system piping dry.

B. IN FIrE CoNDITIoNsIn a fire condition, when a releasing device operates, pressure in the pneumatic release system escapes, causing the pneumatic actuator (F.1) to open. Pressure is released �rom the priming chamber �aster than it is supplied through restricted orifice (�.�).(F.1) to open. Pressure is released �rom the priming chamber �aster than it is supplied through restricted orifice (�.�).to open. Pressure is released �rom the priming chamber �aster than it is supplied through restricted orifice (�.�).(�.�).. The deluge valve clapper opens to allow water to flow into the system piping and alarm devices. When a sprinkler head opens, water will flow �rom the system. I� a sprinkler opens prior to operation o� a releasing device, OR ANY TIME PRE��URE IN THE �PRINKLER PIPING I� LO�T, the pneumatic actuator (F.1) will open. The deluge valve will open and water will flow �rom any open sprinklers and/or any other(F.1) will open. The deluge valve will open and water will flow �rom any open sprinklers and/or any other will open. The deluge valve will open and water will flow �rom any open sprinklers and/or any other opening in the sprinkler system piping. When the deluge valve operates, the sensing end o� the PORV (�.1�) is pressurized, causing the PORV to operate. When the(�.1�) is pressurized, causing the PORV to operate. When theis pressurized, causing the PORV to operate. When the PORV operates, it continually vents the priming chamber to prevent the deluge valve �rom resetting even i� the open releasing devices close. The deluge valve can only be reset a�ter the system has been taken out o� service and the outlet chamber o� the deluge valve and associated trim piping are depressurized and drained.

C. mANuAL opErATIoNmANuAL opErATIoNAny time the handle inside emergency release (�.11) is pulled, pressure is released �rom the priming chamber; the deluge valve will open but the water will be contained in the sprinkler piping. The water motor alarm (C.�) and alarms connected to the alarm pressure switch (C.1) will activate. I� a sprinkler head opens, water will flow �rom the system.

�. �et the release system air pressure supervisory switch to activate at �5 P�I (1.7 bar) on pressure drop �or system water pressures o� 175 P�I (1� bar) or less. For system water pressures above 175 P�I, up to a ma�imum o� �5� P�I (17 bar), set the air pressure supervisory switch to activate at 45 P�I (�.4 bar) on pressure drop. The air pressure supervisory switch should be wired to activate an alarm to signal a low air pressure condition. Activation o� an alarm to signal a high pressure condition may be required. Re�er to applicable installation standards and the Authority Having Jurisdiction.

�. The alarm pressure switch should activate when pressurized to 4 to 8 P�I (�.� to �.�� bar) on pressure rise. The alarm pres-(�.� to �.�� bar) on pressure rise. The alarm pres- on pressure rise. The alarm pres-sure switch should be wired to activate the water �low alarm.

B. AIr suppLy DEsIgNThe air supply compressor should be sized to establish total required air pressure in �� minutes. The air supply must be regu-lated, restricted, and maintained automatically.The air supply must be regulated to maintain the pneumatic pressure desired in the release system and the pneumatic pres-sure desired in the sprinkler piping. Pressures in e�cess o� the pressure settings recommended in section 4. IN�TALLATION, may a��ect operation o� the system.The air supply must be restricted to ensure that the automatic air supply cannot replace air as �ast as it escapes when a re-leasing device or a sprinkler operates.It is recommended practice to provide inspector’s test connections on both the pneumatic release system and the sprinkler piping. The sprinkler system inspector’s test connection should be equipped with a ball valve (normally locked closed) capable o� being opened to simulate the opening o� a sprinkler and should terminate in an orifice equal to the smallest sprinkler orifice provided on the system. The sprinkler system inspector’s test connection should be installed at the most hydraulically demand-ing location o� the system. The inspector’s test connection provided on the pneumatic release system should be equipped with a ball valve (normally locked closed) capable o� being opened to simulate the opening o� a releasing device. Locate the connection and valve at the highest and most demanding location o� the release system. Test connections provided on pneumatic release systems should terminate in an orifice equal to the smallest orifice o� the releasing devices provided. The inspector’s test connection may be used to veri�y that the automatic air supply cannot replace air as �ast as it escapes when a releasing device operates. Re�er to section 7. IN-�PECTION� and TE�T�.
