General Description
The Reliable Model DDX 4” (100 mm) and 6” (150 mm)
PrePaKs are completely self-contained, supervised
preaction systems that can be readily installed within a floor
space of 4.7 ft2(0.44 m2) (not including door swing).
Installation of the PrePaK (not including exterior devices,
i.e., detectors and alarm bells), requires just three piping
connections: a 4” (100 mm) or 6” (150 mm) supply line, a 4”
(100 mm) or 6” (150 mm) system line, and a 2” (50 mm)
drain line. Reference locations of these piping connections
are shown in Fig.1. Also, two 120 / 220 VAC electrical
supply connections are required. Note: The Model DDX
PrePak is available with its air compressor and Potter Model
PFC-4410-RC Releasing/Control Panel wired for a 120 VAC
/ 60Hz or for a 220 VAC / 50 Hz power supply.
The Reliable Model DDX PrePaK contains the following
components within its 25.7” (0.65 m) W x 28.9” (0.73 m) D x
68” (1.73 m) H 12-gauge steel enclosure:
•One Reliable Model DDX 4” (100 mm) or 6” (150 mm)
Deluge Value with Type D Double Interlock Preaction
Trim set (See Reliable Bulletin 728).
•One Gast Model 5HCD-108-M550NGX ¾ Hp Air
Compressor (a 1½ Hp Model 7HDD-16-M750X, Air
Compressor is optional in the 6” (150 mm) PrePaK only).
•One 8 gallon (30.3 liter) air tank.
•One Potter Model PFC-4410-RC Releasing/Control
Panel (See Potter Manual #5403550).
•One Pressure Maintenance Device for system air
supervision (contains regulator, check valve, strainer,
and rapid-fill option).
•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 DDX PrePaK utilizes the 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. Because the PFC-4410-RC is
totally zone and output programmable, 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 detectors, output
devices, and relay contacts may be connected to achieve
the desired system implementation.
The Model DDX 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 inadvertent
water flow into the sprinkler system piping.
The major benefits of a single/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 sprinkler
head occurs.
B. An annunciator signals whenever the integrity of piping
or 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 and operated sprinkler
head.
In single interlock applications, one electrical detector
senses the presence of fire, thereby causing the electrical
releasing control panel to activate fire alarm devices and
energize the solenoid releasing valve in the open position.
Note that arranging detectors in a cross-zoned pattern will
require operation of two detectors before the solenoid valve
can open (Note: Cross-zoned detection systems are not
permitted in New York City and are not Factory Mutual
Approved). The solenoid valve, when closed, is preserving
supply water pressure in the deluge valve’s push-rod
chamber. Actuating the solenoid valve releases that water
pressure which allows the valve to open.
To fully operate a single interlock system with
cross-zoned detection, two separate electrical detection
systems must activate and a sprinkler must open. During
the early stages of a fire, smoke or heat activates the first
detector, which causes the control panel to produce a local
alarm and an alarm at the main fire alarm panel. Electrical
relays inside the releasing control panel can be used to
shut down air moving equipment or activate security doors
and other electrical devices when the panel goes into this
first condition. Subsequent activation of a second, nearby
or adjacent detector, on a separate detection system, will
cause the panel to energize the solenoid valve open and
release water into the sprinkler piping. Water flowing into
the sprinkler piping will simultaneously produce water
pressure that causes the transfer 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 effectively converts the dry system into
a wet pipe system. In the event the fire subsequently
produces sufficient heat to operate a sprinkler head, water
will flow from that sprinkler, controlling the fire.
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, both an electric signal and a pneumatic signal,
must coexist at the releasing control panel, which only then
will energize the solenoid releasing valve, causing 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 head is accidentally opened, the system pressure
switch will operate and an alarm will sound. The riser
assembly, however, will not release water since the
solenoid valve remains closed due to only one input into the
releasing control panel.
When using the Reliable Model DDX PrePaK, in either
single or double interlock applications, the sprinkler system
is pressurized (supervised) with air provided by the air
compressor 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 attached
to a ball valve. The valve handle in its OFF position 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 designed to allow, in
case of an emergency, forceful turning of the valve handle
to the ON position.

System Supervising Pressure Requirements
In accordance with NFPA 13, when using the Reliable
Model DDX 4” (100 mm) or 6” (150 mm) PrePaK in double
interlock applications, 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 remain open in order to provide
maximum intake air flow to the air compressor. The air
compressor is connected to an 8 gallon (30.3 liter) 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 (refer to Fig. 8), is factory set to maintain system
pneumatic pressure at approximately 10 psi (0,7 bar).
Readjusting system pressure to approximately 10 psi (0,7
bar), if necessary, is accomplished by first loosening the
locknut on the air pressure regulator and turning the
adjustment screw (refer to Fig. 8). 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 correct level of pneumatic
pressure.
The system air pressure switch (refer to Fig. 8) is factory
set to operate between 8 psi and 4 psi (0,6 bar and 0,3 bar)
with decreasing pressure. Adjustment, if required, should
be made according to System Sensor Bulletin A05-0176
included with the switch.
System Electrical Requirements
All releasing, alarm, and detection devices in the Reliable
Model DDX 4” (100 mm) and 6” (150 mm) PrePaKs are
supervised by a Potter Model PFC-4410-RC Releasing
Control Panel. To utilize one of the doors of the steel
enclosure as a mount for the releasing control panel, all of
the terminals are translated to two, water-tight terminal
boxes mounted on the interior of the enclosure. Note: the
EOL (End of Line) resistors have also been relocated. It is
from these terminal boxes that all field wiring is connected.
There is one terminal box that contains the 24 VDC
connections and one that contains the 120 / 220 VAC
connections. The Reliable Model DDX PrePaK is delivered
with five factory-installed electrical devices. They consist of
the following:
1. A system air pressure switch, which is used to monitor
sprinkler piping.
2. An alarm pressure switch, which indicates an actuation
of the deluge valve.
3. A normally-closed, releasing solenoid valve, which is
used to actuate the deluge valve.
4. A ¾ HP tank-mounted air compressor with 8 gallon
(30.3 liter) tank (1½ HP compressor is optional with 6”
(150 mm) system only).
5. A supervised butterfly water control valve.
5.
The factory electrical connections of these devices are
illustrated in Fig. 4. For information on how to install fire
detection devices to initiating Zones 1 and 2 of the Potter
Model PFC-4410-RC Releasing Control Panel, refer to Fig.
5 or Fig. 6. For information on how to install output devices,
i.e., alarm bells or trouble annunciators, to the Potter Model
PFC-4410-RC Releasing Control Panel, refer to Fig. 7. The
power supply, standby emergency power supply, battery
charger and rectifier circuitry are all contained within the
PFC-4410-RC panel. Batteries that provide 90 hours of
standby power are provided with the panel. For additional
information and detailed wiring diagrams, refer to Potter
Manual #5403550, Installation, Operation and Instruction of
PFC-4410-RC Releasing Control Panel.
Caution: Repairs or disassembly of the solenoid valve
should only be done by a trained technician. An
improperly repaired or partially assembled solenoid valve
could result in failure of the valve to operate.
System Operation (Single Interlock)
To fully activate (water flow) the Reliable Model DDX 4”
(100 mm) or 6” (150 mm) PrePaK in a single interlock
application, a fire detection device (smoke, heat, etc.) (two
detectors with cross-zoned detection) must activate.
Subsequently, a sprinkler head must open to discharge
water on the fire.
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 position
against the water supply pressure.
Energizing the releasing solenoid valve allows the deluge
valve’s push-rod chamber to be vented to drain through its
outlet. 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 Bulletins 510 and 511 for further details.
Once the clapper has opened, the lever acts as a latch,
preventing the clapper from returning to the closed
position. 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 Control
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 (see
Fig.8). Restore detection devices by resetting or replacing
any operated device. Once detection 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.

6.
System Operation (Double Interlock)
To fully activate (water flow) the Reliable Model DDX 4”
(100 mm) or 6” (150 mm) PrePaK in a double interlock
application, 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’s
pneumatic 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 position
against the water supply pressure.
Energizing the releasing solenoid valve allows the deluge
valve’s push-rod chamber to be vented to drain through its
outlet. 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 Bulletins 510 and 511 for further details.
Once the clapper has opened, the lever acts as a latch,
preventing the clapper from returning to the closed
position. 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 Control
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 (see
Fig.8). Restore detection devices by resetting or replacing
any operated device. Once detection 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.
Maintenance
The Reliable Model DDX PrePaK and associated
equipment shall periodically be given a thorough
inspection and test. NFPA 25, Inspection, Testing and
Maintenance 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 (refer to Fig. 8) beneath the
air tank to drain any condensate accumulation. Bulletin 510
provides information for maintaining the Model DDX
Deluge Valve. Potter Manual #5403550 provides
information for maintaining the PFC-4410-RC Releasing
Control Panel.
Resetting Single And Double Interlock
Systems
Refer to Fig. 8.
1. Close the main valve controlling water supply to the
deluge valve and close the ¼” air shutoff valve, valve J.
2. Close the pushrod chamber supply valve, valve A.
3. Open the main drain valve, valve B, 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 valve D. 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, valve F, to force
the ball from its seat, and drain any water in the alarm
line.
6. With the Model B Manual Emergency Station, valve D,
open, push in and rotate the deluge valve’s external
reset knob clockwise until you hear a distinct clicking
noise, indicating that the clapper has closed. Note:
The reset knob can be rotated only after pressure in the
pushrod chamber is reduced to atmospheric
conditions (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
positions:
valve C – open, valve E – closed, valve H – closed,
valve K – open, valve M – closed.
9. Open valve A and allow water to fill the deluge valve’s
pushrod chamber. Close valve D.
10. Bleed any air from the actuation piping by energizing
the solenoid valve. This is done by operating a
detector or an electric manual emergency 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 Releasing Control Panel.
Note: All detection devices must be reset before the
releasing/control panel can be reset.
11. Open the ¼” air shutoff valve, valve J, to restore air
pressure in the sprinkler system. The rapid air-fill
shutoff valve, valve M, may be opened here to
expedite the filling of the sprinkler system.
12. Open slightly the main valve controlling water supply to
the Model DDX Deluge Valve, closing drain valve B
when water flows. Observe if water leaks through the
ball drip valve, valve F, into the drip cup, G. If no leak
occurs, the deluge valve’s clapper is sealed. Open
slowly, and verify that the main valve controlling water
supply is fully opened and properly monitored.
13. Verify that valve A is open.
14. Secure the handle of the Model B Manual Emergency
Station,valveD,intheOFFpositionwithanylontie
(supplied with the assembly).
15. Press the system reset button on the Potter
PFC-4410-RC Panel to place the system in the ready

Inspection And Testing Of Single And
Double Interlock Systems
Refer to Fig. 8.
1. Water supply — Verify that the valve controlling water
supply to the deluge valve is opened fully and properly
monitored.
2. Alarm line — Verify that valve C is opened and
remains in this position.
3. Other trimming valves — Verify that valve A is open
as well as all of the pressure gauge’s ¼” 3-way valves.
Valves D, E, and H should be closed.
4. Ball drip valve F — Push in on the plunger to be sure
the ball check is off its seat. If no water appears, the
deluge valve’s water seat is tight. Inspect the bleed
hole in the front of the Model DDX Deluge Valve 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 releasing
device (i.e., solenoid valve or the Model B Manual
Emergency Station, valve D) for leakage. Also verify
that tubing drain lines from releasing devices are not
pinched or crushed which could prevent proper
releasing of the deluge valve.
7. Testing alarms — Open valve E permitting water from
the supply to flow to the alarm pressure switch and to
the mechanical sprinkler alarm (if present). After
testing, close this valve completely. Push in on the
plunger of ball drip valve F until all of the water has
drained from the alarm line.
8. Operational test — Open the Model B Manual
Emergency Station, valve D only, OR, operate the
solenoid valve by electrical actuation. This is done by
operating a detector or an electric manual emergency
station. Double interlock systems also require that the
sprinkler system’s 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, valve
D, in the OFF position with a nylon tie (included with the
assembly) after the deluge valve is reset.
Testing The Model DDX PrePaK Without
Causing Water Flow
Refer to Fig. 8.
1. Close the main valve controlling water supply to the
deluge valve and open drain valve B.
2. Verify that valve A is open, allowing water to enter the
push-rod chamber.
3. Operate the detection system - Operate a cross-zoned
releasing control panel by operating two detectors. For
double interlock applications, close valve J and open
valve H. Doing so will discharge the sprinkler system’s
air pressure.
4. Step #3 should result in a sudden drop of water
pressure in the deluge valve’s push-rod chamber via
an energized solenoid valve.
5. Reset the detection system - Reverse the detection
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
“Resetting Single And Double Interlock Systems”
section of this bulletin.
Draining Excess/Condensate Water From
The System
Refer to Fig. 8.
1. Close the main valve controlling water supply to the
deluge valve. Also, close valve A and open the main
drain valve, valve B.
2. Open the condensate drain valve, valve H, until all of the
water (if any) drains completely. Note: Be sure not to
keep valve H open for an extended period of time
because that will cause enough system air to bleed off,
thereby activating the system pressure switch and
causing an potentially undesirable alarm condition.
3. Close the main drain valve B. Allow the system’s air
pressure to return to its previous level. Open valve A
first, and then open the main valve controlling the water
supply to the deluge valve.
