General Description
The Reliable Type F Model DDX PrePaK system with inte-
grated nitrogen generation is a completely self-contained, su-
pervised preaction system that can be readily installed within
a floor space of less than 7 ft
swing). Refer to Fig. 1 for cabinet dimensions. Installation 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 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 Reli-
able Automatic Sprinkler Company website (www.reliablesprin-
kler.com)
The Reliable Model DDX N2-Blast
rates a South-Tek Systems FPS-900 pressure swing adsorp-
tion N2-Blast nitrogen generator, complete with independent
®
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 Systems website (www.southteksys-
tems.com).
The Reliable Type F PrePaK system utilizes an optional Potter
Model PFC-4410-RC Releasing/Control Panel. This fully pro-
grammable, microprocessor-based releasing panel is Under-
writers 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 installed devices. Once the
previously described connections are completed, the 24 VDC
detectors, output devices, and relay contacts may be connect-
ed to achieve the desired system implementation.
