General Description
The Reliable Model DDX PrePaK system with integrated
nitrogen generation is a completely self-contained, super-
vised preaction system that can be readily installed within
a floor space of less than 7 ft
swing). Installation of the PrePaK system (not including ex-
terior devices, i.e., detectors and alarm bells) requires three
piping connections: the water supply, the sprinkler system,
and the drain. Reference locations of these piping connec-
tions are shown in Fig.1. Independent electrical supplies are
required for the optional system air compressor (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 the South-Tek Sys-
tems website (www.southteksystems.com).
The Reliable Model DDX PrePaK system utilizes an option-
al Potter Model PFC-4410-RC Releasing Control Panel. This
fully programmable, microprocessor-based releasing panel
is Underwriters Laboratories, Inc. Listed and is in compli-
ance with NFPA 13 and NFPA 72. The PFC-4410-RC is
totally zone and output programmable such that the Reli-
able Model DDX PrePaK system can be utilized in many dif-
ferent preaction applications without having to rewire any of
the factory installed 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.
