I. SYSTEM DESCRIPTION
A Preaction System is a sprinkler system employing closed automatic sprinklers connected to a piping
system that contains air or nitrogen that may or may not be pressurized. A supplemental detection system
(release line) is installed in the same area as the sprinklers. The basic components of a Viking preaction
system include a Model E or F series deluge valve and conventional deluge trim (Figure 1), or a Model
G-2000P, G-3000P, or G-4000P valve assembly (Figure 2) and trim. The associated release trims are
unique to the specific type of preaction system desired (Figures 3-6). For systems using a Model E or F
series deluge valve, an Easy Riser
®
Check Valve is also typically added to the riser when supervisory air is
required within the sprinkler system piping network (Figure 7). NOTE: The Model G series valve includes
an internal check valve, eliminating the need for a separate check valve on the system riser. The G series
valve assembly also includes all the necessary trim components for the preaction system operation.
NOTE: SPRINKLER SYSTEMS ARE ENGINEERED TO MEET THE STANDARDS OF NFPA 13, FM GLOBAL,
LOSS PREVENTION COUNCIL (FOC), ASSEMBLEE PLENIERE, VERBAND DER SACHVERSICHERER
(VDS) OR OTHER SIMILAR ORGANIZATIONS, AND WILL ALSO NEED TO COMPLY WITH THE PRO
VISIONS OF GOVERNMENTAL CODES, ORDINANCES, AND STANDARDS WHERE APPLICABLE.
THE SYSTEM MUST BE DESIGNED BY QUALIFIED DESIGN PROFESSIONALS IN CONJUNCTION
WITH INSURING BODIES. THE USER IS RESPONSIBLE FOR THE DESIGN AND CONFIGURATION OF
THE SYSTEM, ITS APPROPRIATENESS FOR THE USE INTENDED AND ITS COMPLIANCE WITH ALL
STANDARDS, CODES AND ORDINANCES. VIKING CORPORATION DOES NOT DESIGN SYSTEMS
FOR SPECIFIC INSTALLATIONS AND MAKES NO REPRESENTATION OR WARRANTY CONCERNING
WHETHER ANY SPECIFIC SYSTEM INSTALLATION WILL BE SUFFICIENT FOR THE INTENDED USE
OR WILL COMPLY WITH ANY STANDARD, CODE, OR ORDINANCE. ANY SYSTEM DEPICTED IN THIS
MANUAL IS SHOWN FOR ILLUSTRATIVE PURPOSES ONLY.
