Description Page
1. Introduction
The Reliable Model DDX PrePaK™is a completely self-contained, supervised system that can be readily installed within a floor
space (not including door swing) of 4.7 ft2(0.43 m2) for 2” through 4” systems, and 6.5 ft2(0.60 m2) for 6” and 8” systems and
those systems incorporating a nitrogen generator.
Installation of the PrePaK™requires three piping connections: the water supply, the sprinkler system, and the drain. Reference
locations of these piping connections, along with general PrePaK™ dimensions are shown on gures 1 and 2 of this document.
Individual power circuits are required for the releasing control panel, air compressor, and nitrogen generator, where so
equipped. Depending on the type of system and requirements of the project, eld wiring of detection devices and noticaiton
devices may be required. When equipped with an integral releasing conrol panel, connection of the panel to the main building
re alarm system may also be required.
2. Scope
This document is intended to provide detailed information on the installation, operation, and maintenance of Reliable Model
DDX PrePaK™cabinet mounted systems. Basic information for the selection and ordering of units is provided on technical
bulletin 760 that is available on the Reliable website (www.reliablesprinkler.com).
This document does not contain information on the design, applicability, or installation of the automatic re detection system
that may be necessary for complete operation of the system. Design and installation of re detection and alarm systems must
be performed by qualied design professionals and approved by all authorities having jurisdiction.
This document is not intended to replace or revise any requirements of the National Fire Protection Association (NFPA), FM
Global, and/or any authorities having jurisdiction (AHJ) that may govern an installation. Design and installation requirements
for re protection systems must be independently evaluated by qualied design professionals and approved by all authorities
having jurisdiction.
3. Product Descriptions & References
Pages 4 through 21 provide descriptions of each available system, additional (related) product references, and diagrams of
major system components. Full assembly drawings are available on the Reliable website (www.reliablesprinkler.com).

Product: Model DDX Type D Single/Double Interlock Preaction System
The Reliable Model DDX Type D preaction system is an electric release system that incorporates a 24VDC normally closed so-
lenoid valve on the deluge valve releasing trim. The solenoid valve is energized by a listed release control panel and detection
system when the appropriate type and number of events have occurred to satisfy the panel program.
For single interlock preaction systems, the activation of a supplemental electric detection system, either on a single zone or
two zones (cross zoned) will energize the solenoid, releasing water into the system and initiating a water flow alarm.
For double interlock preaction systems, the activation of a supplemental electric detection system in conjunction with activation
of the low-pressure switch due to loss of system pneumatic pressure (presumed due to a re sprinkler opening) will energize
the solenoid, releasing water into the system and initiating a water flow alarm.
In the event of pneumatic pressure loss on the system with no active electric detection, the pressure switch will operate inde-
pendently, and a supervisory signal will report to the re alarm system, however, water will not be released into the system.
This system, in sizes 2” through 6” (50 mm to 150 mm), is also available with an integral SouthTek Systems FPS-900 N2-
Blast® nitrogen generator, FM Approved to Standard 1035, Nitrogen Generators for Corrosion Mitigation.
