General Description
The Reliable Model DDX PrePaK with integrated ni-
trogen generation is a completely self-contained, su-
pervised preaction system that can be readily installed
within a floor space of less than 7 ft2(0.65 m2) (not includ-
ing door swing). Installation of the PrePaK (not including
exterior devices, i.e., detectors and alarm bells) requires
three piping connections: the water supply, the sprinkler
system, and the drain. Reference locations of these pip-
ing connections are shown in Fig.1. Independent electri-
cal 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.re-
liablesprinkler.com).
The Reliable Model DDX N2-Blast®PrePak incorporates
a South-Tek Systems FPS-900 pressure swing adsorption
N2-Blast®nitrogen generator, complete with independent
air compressor, nitrogen storage tank, and control sys-
tem. The nitrogen generator is completely wired, tested,
and integrated with the Model DDX PrePak, and supplies
98% pure nitrogen to the piping network to limit electro-
chemical, 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 utilizes an optional
Potter 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. The PFC-4410-
RC is totally zone and output programmable such that
the Reliable Model DDX PrePaK 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 de-
tectors, output devices, and relay contacts may be con-
nected to achieve the desired system implementation.

The Model DDX Type D PrePaK can be used in both
single and double interlock applications. Reliable Single
and Double Interlock Preaction Systems are designed for
water sensitive areas that require protection from inad-
vertent water flow into the sprinkler system piping.
The major benefits of a single/double interlock preac-
tion 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 sprin-
kler occurs.
B. An annunciator signals whenever the integrity of pip-
ing or sprinklers is accidentally or intentionally dis-
turbed; however, no water flow occurs unless the de-
tection system has been activated .
C. Detection and notification of a fire condition are pro-
vided 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
sprinkler.
In single interlock applications, one or more detectors
sense the presence of fire, thereby causing the electrical
releasing control panel to activate notification appliances
and energize the solenoid releasing valve to the open
position. The use of cross-zoned detectors will require
operation of two detectors on separate zones before the
solenoid valve can open (Note: Verify that the detection
method, including the use of cross-zoned detection, are
permitted by all applicable codes and standards, as well
as the requirements of all authorities having jurisdiction.
Cross-zoned detection may not be permitted in New York
City or by Factory Mutual.) The solenoid valve, when
closed, preserves supply water pressure in the Model
DDX valve’s push-rod chamber. Actuating the solenoid
valve releases that water pressure which allows the Mod-
el DDX valve to open.
To discharge water from sprinklers on a single interlock
system with cross-zoned detection, two separate elec-
trical detection zone must activate and a sprinkler must
open. During the early stages of a fire, smoke or heat ac-
tivates the first detector, which causes the control panel
to produce a local alarm and an alarm at the fire alarm
panel. Electrical relays inside the releasing control panel
can be used to shut down air moving equipment or acti-
vate security doors and other electrical devices when the
panel goes into this first condition. Subsequent activa-
tion of a second, nearby or adjacent detector, on a sepa-
rate detection zone, will cause the panel to energize the
solenoid valve open and release water into the sprinkler
piping. Water flowing into the sprinkler piping will simul-
taneously produce water pressure that cause the trans-
fer of contacts in the alarm pressure switch mounted in
the riser assembly, thereby activating a water flow alarm
device. The flow of water into the sprinkler piping effec-
tively converts the dry system into a wet-pipe sprinkler
system. In the event that the fire subsequently produces
sufficient heat to operate a sprinkler, water will flow from
that sprinkler.
To flow water into a double interlock preaction system,
two events must take place: a fire detection device must
operate, and a pressure switch must be operated by the
loss of system pressure (sprinkler operation). These two
signals, an electric signal from the detection system and
an electrical signal from the pressure (pneumatic) sen-
sor, must coexist at the releasing control panel, which
only then will energize the solenoid releasing valve caus-
ing water flow into the sprinkler system and out of the
open sprinkler(s).
In the event that the system piping is ruptured or a
sprinkler is accidentally opened, the system pressure
switch will operate and an alarm will sound. The Model
DDX Type D however, will not release water since the
detection system has not been activated.
When using the Reliable Model DDX PrePaK in either
single or double interlock applications, the sprinkler sys-
tem is pressurized (supervised) with air or nitrogen and
is monitored by a system pressure switch.
A Model B Hydraulic Manual Emergency Releasing
station is standard equipment in the Model DDX PrePaK.
It consists of an aluminum nameplate mechanically at-
tached to a ball valve. The valve handle in its OFF po-
sition is guarded against accidental turning to the ON
position (and system discharge) by a nylon cable tie
provided with the PrePaK assembly. The cable tie is de-
signed to allow, in case of an emergency, forceful turning
of the valve handle to the ON position.

Installation Requirements
The automatic sprinklers, releasing devices, fire detec-
tion devices, manual pull stations, and signaling devices
which are utilized with the Reliable Model DDX Type D
PrePaK must be UL and/or ULC Listed or FM Approved,
as applicable.
The steel enclosure and all the interconnecting piping
must be located indoors in a readily visible and acces-
sible location and in an area that can be maintained at
a minimum temperature of 40°F (4°C). Note: Heat trac-
ing is not permitted. The solenoid valve is operated and
supervised by the Potter Model PFC-4410-RC Releasing
Control Panel. Details on the electrical connections of
this system to the Potter Panel can be found in the Potter
Manual #5403550, Installation, Operation and Instruction
of PFC-4410-RC Releasing Control Panel (this manual is
included with other pertinent manuals and shipped in-
side the enclosure). This panel is fully zone and output
programmable and may be adapted to several applica-
tions.
System Supervising Pressure Requirements
In accordance with NFPA 13, when using the Reliable
Model DDX Type D PrePaK in double interlock applica-
tions, a minimum of 7 psi (0.5 bar) pneumatic pressure is
required to supervise the sprinkler system. When initially
filling the system with air, the enclosure’s door should re-
main open in order to provide maximum intake air flow
to the air compressor. The air compressor is connected
to an ASME rated storage tank. This tank functions as a
reservoir, providing make-up air to compensate for small,
intermittent leaks in the sprinkler system. It should be
noted that significant leaks may overburden this storage
tank, thereby causing the air compressor to continuously
cycle on and off.
The Pressure Maintenance Device supplied with the
system is factory set to maintain system pneumatic pres-
sure at approximately 10 psi (0.7 bar). Readjusting sys-
tem pressure to approximately 10 psi (0.7 bar), if neces-
sary, is accomplished by first loosening the locknut on
the air pressure regulator and turning the adjustment
screw. The system air pressure gauge that is attached
to the vertical pipe/manifold (mounted directly above the
Model DDX Deluge Valve) may be used to verify the cor-
rect level of pneumatic pressure.
The system air pressure switch is factory set to oper-
ate between 8 psi and 4 psi (0.6 bar and 0.3 bar) with
decreasing pressure.
System Electrical Requirements
All releasing, alarm, and detection devices in the Reli-
able Model DDX Type D PrePaK are supervised by a Pot-
ter Model PFC-4410-RC Releasing Control Panel. All of
the terminals are translated to a water-tight terminal box
mounted on the interior of the enclosure. All field wiring
is connected to this terminal box. Note: The EOL (End of
Line) resistors have also been relocated.
The Reliable Model DDX PrePaK is delivered with six
factory-installed electrical devices. They consist of the
following:
1. A system air pressure switch, which is used to moni-
tor sprinkler piping.
2. An alarm pressure switch, which indicates an actua-
tion of the deluge valve.
3. A normally-closed, releasing solenoid valve, which is
used to actuate the deluge valve.
4. A 1/2 HP (2”, 2-1/2”, & 3” valve), or 1 HP (4” valve) air
compressor with tank.
5. A supervised butterfly (main control) valve (Note: A
system side butterfly valve is available as an option).
6. A release control disable switch (RCDS) which is
used to disable the solenoid valve for test purposes.
The factory electrical connections of these devices, along
with information on the connection of detection devices
(initiating zones 1 and 2), signaling devices, and supervi-
sory outputs to the Potter PFC4420-RC Releasing Control
Panel are included in this bulletin. The power supply,
standby emergency power supply, battery charger and
rectifier circuitry are all contained within the PFC4410
panel. Batteries that provide 90 hours of standby power
are provided with the panel. For additional information
and detailed wiring diagrams, please refer to Potter Man-
ual #5403550 (Installation, Operation, and Instruction of
PFC4410-RC Releasing Control Panel).

5.
Note: In order for the solenoid valve to maintain a warranty
it must remain sealed as it came from the factory. If there are
concerns about the valve’s internal components, immediate re-
placement is recommended.
System Operation (Single Interlock)
To fully activate and discharge water from the Reliable
Model DDX Type D PrePaK in a single interlock appli-
cation, a fire detection device (smoke, heat, etc.; or two
devices with cross-zoned detection) must activate. Sub-
sequently, a fire sprinkler must open.
When the single interlock preaction system is set for
service, the supply pressure acts both on the underside
of the deluge valve’s clapper and on the valve’s push
rod by means of the pressurized push rod chamber. The
pressure force acting on the push rod, when utilized with
the mechanical advantage of the deluge valve’s lever, is
more than sufficient to hold the clapper in the closed po-
sition against the water supply pressure.
Energizing the releasing solenoid valve allows the
deluge valve push-rod chamber to be vented to drain.
Since the pressure cannot be replenished through the
inlet restriction as rapidly as it is vented though the outlet,
the push-rod chamber pressure falls rapidly. When the
push-rod chamber pressure drops below one-third of the
supply pressure, the opening force acting beneath the
clapper becomes greater than the push-rod force acting
on the lever. This causes the clapper to open. Refer to
Reliable Bulletin 519 for further details.
Once the clapper has opened, the lever acts as a latch,
preventing the clapper from returning to the closed po-
sition. Water from the supply flows through the deluge
valve into the system piping. Water also flows through the
deluge valve alarm outlet to activate any water flow alarm
devices. Note that the solenoid valve will be maintained
open by the Potter Model PFC-4410-RC Releasing Con-
trol Panel’s latching feature until it is reset for operation.
After system shutdown and draining, the Model DDX
Deluge Valve is easily reset without special tools using
the external reset feature. Restore detection devices by
resetting or replacing any operated device. Once detec-
tion devices are restored, (the Potter Model PFC-4410-
RC Releasing Control Panel reset), and supply pressure
is re-supplied to the push-rod chamber, the deluge valve
is reset.
System Operation (Double Interlock)
To fully activate and discharge water from the Reliable
Model DDX Type D PrePaK in a double interlock applica-
tion, two independent events must coexist. An electrical
fire detection device (smoke, heat, etc.) and the system
air pressure switch must be activated. This pressure
switch is activated by a reduction of the system pneu-
matic pressure as a result of sprinkler operation. Both
of these events will cause the control panel to energize
the solenoid valve, thereby releasing water through the
deluge valve and into the sprinkler system. The initiation
of either one of these events will only cause an alarm to
annunciate, and will not fill the sprinkler system.
When the double interlock preaction system is set for
service, the supply pressure acts both on the underside
of the deluge valve’s clapper and on the valve’s push
rod by means of the pressurized push rod chamber. The
pressure force acting on the push rod, when utilized with
the mechanical advantage of the deluge valve’s lever, is
more than sufficient to hold the clapper in the closed po-
sition against the water supply pressure.
Energizing the releasing solenoid valve allows the
deluge valve push-rod chamber to be vented to drain.
Since the pressure cannot be replenished through the
inlet restriction as rapidly as it is vented though the outlet,
the push-rod chamber pressure falls rapidly. When the
push-rod chamber pressure drops below one-third of the
supply pressure, the opening force acting beneath the
clapper becomes greater than the push-rod force acting
on the lever. This causes the clapper to open. Refer to
Reliable Bulletin 519 for further details.
Once the clapper has opened, the lever acts as a latch,
preventing the clapper from returning to the closed po-
sition. Water from the supply flows through the deluge
valve into the system piping. Water also flows through the
deluge valve alarm outlet to activate any water flow alarm
devices. Note that the solenoid valve will be maintained
open by the Potter Model PFC-4410-RC Releasing Con-
trol Panel’s latching feature until it is reset for operation.
After system shutdown and draining, the Model DDX
Deluge Valve is easily reset without special tools using
the external reset feature. Restore detection devices by
resetting or replacing any operated device. Once detec-
tion devices are restored, (the Potter Model PFC-4410-
RC Releasing Control Panel reset), and supply pressure
is re-supplied to the push-rod chamber, the deluge valve
is reset.
Resetting Single And Double Interlock Systems
1. Close the main valve controlling water supply to the
deluge valve and close the ¼” air shutoff valve.
2. Close the pushrod chamber supply valve.
3. Open the main drain valve and drain system.
4. Open all drain valves and vents at low points
throughout the system, closing them when flow of
water has stopped. Open the Manual Emergency
Release Valve. Note: The above steps accomplish
the relieving of pressure in the pushrod chamber of
the deluge valve.
5. Push in the plunger of ball drip valve to force the ball
from its seat, and drain any water in the alarm line.
6. With the Model B Manual Emergency Station open,
push in and rotate the deluge valve external reset
knob counterclockwise (when facing valve) until
you hear a distinct clicking noise, indicating that the
clapper has closed.

6.
Note: The reset knob can be rotated only after pressure
in the pushrod chamber is reduced to atmospheric con-
ditions (0 psig).
7. Inspect and replace any portion of the sprinkler system
subjected to fire conditions.
8. Verify that the following valves are in their respective po-
sitions:
Manual Emergency Release - open
Main Drain Valve - open
Alarm Line Valve - open
Alarm Test Valve - closed
Condensate Drain valve - closed
Air Supply Valves - closed
9. Open the pushrod chamber supply valve and allow wa-
ter to fill the deluge valve pushrod chamber. Close the
Manual Emergency Release valve.
10. Bleed any air from the actuation piping by energizing the
solenoid valve. This is done by operating the electric
manual release station. While water is flowing through
the solenoid valve, cause it to close by pressing the
system reset button on the Potter PFC-4410-RC Releas-
ing Control Panel. Note: All detection devices and the
manual pull station must be reset before the releasing/
control panel can be reset.
11. Open the air supply valve to restore air pressure in the
sprinkler system. The rapid air-fill shutoff valve may be
opened to expedite filling of the sprinkler system.
12. Open slightly the main valve controlling water supply
to the Model DDX Deluge Valve, closing the main drain
valve when water flows. Observe if water leaks through
the ball drip valve into the drain manifold. If no leak oc-
curs, the deluge valve clapper is sealed. Open slowly,
and verify that the main valve controlling water supply is
fully opened and properly monitored.
13. Verify that the pushrod chamber supply valve is fully
open.
14. Secure the handle of the Model B Manual Emergency
Station in the OFF position with a nylon tie (supplied with
the assembly).
15. Press the system reset button on the Potter PFC-4410-
RC Panel to place the system in the ready condition.
Note: All detection devices must be reset before the
panel can be reset.
Maintenance
The Reliable Model DDX PrePaK and associated equip-
ment shall periodically be given a thorough inspection and
test. NFPA 25, Standard for the Inspection, Testing and Main-
tenance of Water Based Fire Protection Systems, provides
minimum maintenance requirements. Systems should be
tested, operated, cleaned and inspected at least annually,
and parts replaced as required. Periodically open the air/
condensate drain valve beneath the air tank to drain any
condensate accumulation. Bulletin 519 provides information
for maintaining the Model DDX Deluge Valve. Potter Manual
#5403550 provides information for maintaining the PFC-
4410-RC Releasing Control Panel.
Inspection And Testing Of Single And Dou-
ble Interlock Systems
1. Water supply — Verify that the valve controlling wa-
ter supply to the deluge valve is opened fully and
properly monitored.
2. Alarm line — Verify that the alarm line valve is
opened and remains in this position.
3. Other trimming valves — Verify that the pushrod
chamber supply valve is open as well as all of the
pressure gauge valves.
4. Ball drip valve — Push in on the plunger to be sure
the ball check is off its seat. If no water appears, the
deluge valve water seat is tight. Inspect the bleed
hole on the underside of the pushrod chamber for
leakage.
5. System pneumatic pressure — Verify that system
air pressure is between 7 and 10 psi (0.5 bar 0.7
bar). Check the Pressure Maintenance Device for
leakage and proper pressure.
6. Releasing device — Check the outlet of the re-
leasing device (i.e., solenoid valve or the Model B
Manual Emergency Station) for leakage. Also verify
that tubing drain lines from releasing devices are not
pinched or crushed which could prevent proper re-
leasing of the deluge valve.
7. Testing alarms — Open the alarm test valve permit-
ting water from the supply to flow to the alarm pres-
sure switch and to the mechanical sprinkler alarm (if
present). After testing, close this valve completely.
Push in on the plunger of ball drip until all of the water
has drained from the alarm line.
8. Operational test — Open the Model B Manual Emer-
gency Station only, OR operate the solenoid valve by
electrical actuation. This can be done by operating
a detector or an electric manual emergency station.
Double interlock systems also require that the system
air pressure be discharged, through the inspectors
test station or other venting means, below 4 psi (0.3
bar) before total system operation will occur. Note:
An operational test will cause the Deluge Valve to
open and flow water into the sprinkler system.
9. Secure the Model B Manual Emergency Station in the
OFF position with a nylon tie (included with the as-
sembly) after the deluge valve is reset.
Testing The Model DDX PrePaK Without
Causing Water Flow
1. Close the main valve controlling water supply to the
deluge valve and open the main drain valve.
2. Verify that the pushrod chamber supply valve is
open, allowing water to enter the push-rod chamber.
3. Operate the detection system. For double interlock
applications, also disable the air supply and open
the condensate drain valve to discharge the system
air pressure.
4. Step #3 should result in a sudden drop of water pres-
sure in the deluge valve push-rod chamber via an
energized solenoid valve.

5. Reset the detection system - Reverse the detec-
tion system operations performed in Step #3 above.
Note: All detection devices must be reset before the
Potter PFC-4410-RC Releasing Control Panel can be
reset.
6. Proceed according to the directions listed in the “Re-
setting Single And Double Interlock Systems” section
of this bulletin.
Draining Excess/Condensate Water From
The System
1. Close the main valve controlling water supply to the
deluge valve and the pushrod chamber supply valve.
Open the main drain valve.
2. Slightly open the condensate drain valve until all
water (if any) drains completely. Note: Leaving the
condensate drain valve open for an extended period
of time may allow excess air to bleed off resulting in
an undesirable low pressure supervisory signal.
3. Close the main drain valve. Allow the system air
pressure to return to its previous level. Open the
pushrod chamber supply valve first, and then open
the main valve controlling the water supply to the del-
uge valve.
SOLENOID VALVE INSPECTIONS, TESTS
AND MAINTENANCE
WARNING: THE OWNER IS RESPONSIBLE FOR MAIN-
TAINING THE FIRE PROTECTION SYSTEM IN PROP-
ER OPERATING CONDITION. ANY SYSTEM MAIN-
TENANCE OR TESTING THAT INVOLVES PLACING A
CONTROL VALVE OR DETECTION SYSTEM OUT OF
SERVICE MAY ELIMINATE THE FIRE PROTECTION
OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY

VALVE TO AVOID UNINTENTIONAL OPERATION OF
THE DELUGE VALVE
1. Inspections: It is imperative that the system be in-
spected and tested in accordance with NFPA 25 on a
regular basis. The frequency of the inspections may
vary due to contaminated water supplies, corrosive
water supplies, or corrosive atmospheres. In addi-
tion, the alarm devices, detection systems, or other
connected trim may require a more frequent sched-
ule. Refer to the system description and applicable
codes for minimum requirements.
2. The valve must be inspected at least monthly for
cracks, corrosion, leakage, etc., cleaned and re-
placed as necessary.
3. If leakage is suspected through the solenoid valve, it
should be replaced.

either conventional zone will operate the general alarm bell. Activation of the waterflow zone will op-
erate the waterflow bell. Activation of either the low air zone or the supervisory zone will operate the
supervisory bell. When either Zone #1 or #2 is in alarm, Output #1 (general alarm) will operate. When
Zones #1 and #2 are in alarm at the same time, Output #4 (solenoid release) and Output #1(general
alarm) will operate. When Zone #3 is in alarm, Output #2 (waterflow bell) will operate. When either
Zone #4 or the supervisory zone is activated, Output #3 (supervisory bell) will operate.
Note:
(1) The Butterfly valve in the PrePaK assembly is connected to Supervisory 2 input of the Potter PFC-4410RC Releas-
ing/Control panel
(2) The emergency manual release within the PrePak cabinet is wired into the conventional detection zones 1 and 2,
and is designed to release the solenoid for setup and testing purposes.
For additional Information, please refer to the “Installation, Operation, and Instruction Manual” for the Potter
PFC4410-RC Releasing Control Panel (provided with the unit).
