Product Description
The Reliable Model H 1½" (40mm) PrePaK system is a completely
self-contained, supervised preaction system that can be readily
installed within a floor space of 4.5 square feet. Installation of
the PrePaK system (not including exterior devices, i.e., detectors
and alarm bells) requires just three piping connections: a 1½"
(40mm) supply line, a 1½" (40mm) system line, and a ¾" (20mm)
drain line. Reference locations of these piping connections are
shown in Figure 1. Also, two 120 VAC (or 220 VAC) electrical
supply connections are required.
The Reliable Model H 1½" (40mm) PrePaK system contains the
following components within its 64" H x 24" W x 27" D (162.6cm
H x 61cm W x 68.6cm D) gauge 12 steel enclosure:
• One Reliable Model H 1½" (40mm) Deluge Riser Assembly
(See Reliable Bulletin 507).
• One Reliable Model A Pressure Maintenance Device (See
Reliable Bulletin 251).
• One Reliable Model G 2½" (65mm) Right-Check Valve™ w/
Preaction Trim Kit (See Reliable Bulletin 806).
• One Gast Model1 1HAB-11T-M100X HP Tank-Mounted Air
Compressor with 2 Gallon (7.6 liter) tank.
• One Potter Model PFC-4410G3 Releasing Control Panel
(See Potter Manual #5403751).
• All required fittings, gauges, electrical connectors, and
electrical devices to utilize the system in single interlock,
single interlock cross-zoned, double interlock, and double
interlock cross-zoned applications.
The Reliable Model H utilizes the Potter Model PFC-
4410G3 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-4410G3 is totally zone and output
programmable, the Reliable Model H PrePaK system can be
utilized in four 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 connected to achieve
the desired system implementation.
The Model H PrePaK system can be used in both single and
double interlock applications. Reliable Single and Double
Interlock Preaction Systems are designed for water sensitive
areas, which require protection from inadvertent water flow into
the sprinkler system piping.

The major benefits of a single and/or double interlock preaction
system, when compared with a wet pipe system, are as follows:
A. A fire alarm sounds prior to the flow of water from a sprinkler,
which may enable extinguishing the fire by handheld means
before the operation of any fire sprinkler occurs.
B. An annunciator signals whenever the integrity of piping or fire
sprinklers is accidentally or intentionally disturbed; however,
no water flow or water damage will result at that time.
C. Speedy detection and an early fire alarm are provided by fire
detectors, without the delay associated with water delivery
time in the event of a fire. Note that with a wet pipe system,
the fire alarm is delayed until after water has begun flowing
from an operated fire sprinkler.
