General Description
The Reliable Type F Model DDX PrePaK system with in-
tegrated nitrogen generation is a completely self-contained,
supervised preaction system that can be readily installed
within a floor space of less than 7 ft
door swing). Refer to Fig. 1 for cabinet dimensions. Instal-
lation of the PrePaK system (not including exterior devices,
i.e., detectors and alarm bells), requires just three piping
connections. These connections are the water supply, the
sprinkler system and the drain. Reference locations of these
piping connections are shown in Fig. 1. Independent electri-
cal supplies are required for the optional system air com-
pressor (115 or 220 VAC), the optional Potter Model 4410
Releasing Control Panel (115/220 VAC), and the nitrogen
generator (115 VAC).
Full assembly drawings for the units are available on the
Reliable Automatic Sprinkler Company website (www.reli-
ablesprinkler.com)
The Reliable Model DDX N2-Blast
porates a South-Tek Systems FPS-900 pressure swing ad-
sorption N2-Blast
nitrogen generator, complete with inde-
®
pendent air compressor, nitrogen storage tank, and control
system. The nitrogen generator is completely wired, tested,
and integrated with the Model DDX PrePaK system, and
supplies 98% pure nitrogen to the piping network to limit
electrochemical, galvanic, and micro-biologically influenced
corrosion (MIC). Operation and maintenance information
can be found in this bulletin as well as at the South-Tek Sys-
tems website (www.southteksystems.com).
The Reliable Type F PrePaK system utilizes an optional Pot-
ter Model PFC-4410-RC Releasing/Control Panel. This fully
programmable, microprocessor-based releasing panel is
Underwriters Laboratories, Inc. Listed and is in compliance
with NFPA 13 and NFPA 72. Because the PFC-4410-RC is
totally zone and output programmable, the Reliable Type F
PrePaK system can be utilized in many different preaction
applications without having to rewire any of the factory in-
stalled devices. Once the previously described connections
are completed, the 24 VDC detectors, output devices, and
relay contacts may be connected to achieve the desired
system implementation.
