General Description
The Reliable Model H 1½” (40mm) PrePaK 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 (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 loca-
tions 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 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-2 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 (See Reliable Bulletin
700).
• One Potter Model PFC-4410-RC Releasing Control Panel (See
Potter Manual #5403550).
• All required fittings, gauges, electrical connectors, and electri-
cal devices to utilize the system in single interlock, single inter-
lock cross-zoned, double interlock, and double interlock cross-
zoned applications.
The Reliable Model H utilizes the Potter Model PFC-4410-RC Re-
leasing 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 H PrePaK can be utilized in four different preaction applica-
tions 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 con-
nected to achieve the desired system implementation.
The Model H PrePaK can be used in both single and double in-
terlock applications. Reliable Single and Double Interlock Preaction
Systems are designed for water sensitive areas, which require pro-
tection 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 sprin-
kler, 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 de-
livery 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 head.
In single interlock applications, one electrical detector senses the
presence of fire, thereby causing the electrical releasing control pan-
el to activate fire alarm devices and latch 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 per-
mitted in New York City and are not Factory Mutual Approved). The
solenoid valve, when closed, is preserving supply water pressure in
the inlet of the Reliable Model H Deluge Riser Assembly. Actuating
the solenoid valve releases that water pressure, allowing water flow
into the sprinkler system in readiness for the subsequent operation
of a sprinkler.
To fully operate a single interlock system with cross-zoned detec-
tion, 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 pro-
duce a local alarm and an alarm at the main fire alarm panel. Elec-
trical 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 alarm 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. Wa-
ter flowing into the sprinkler piping will simultaneously produce water
pressure that causes the transfer of contacts in the 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 subse-
quently 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 pres-
sure switch must be operated by the loss of system pressure (sprin-
kler 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 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 control panel.
When using the Reliable Model H PrePaK in either single or dou-
ble interlock applications, the sprinkler system is pressurized (super-
vised) with air provided by the HP tank-mounted air compressor
and is monitored by the system pressure switch.
A hydraulic manual emergency releasing station is standard
equipment in the Model H PrePaK. It is identified by a nameplate
attached above the releasing valve.
Preaction trim provides a by-pass drain line and the air supply re-
quired to supervise the preaction system at 10 psi (0,7 bar). This trim
includes a UL Listed Reliable Model G Right-Checkä Valve installed
with rigid grooved pipe couplings.

System Supervising Pressure Requirements
In accordance with NFPA 13 (1996), when using the Reliable
Model H 1½” (40mm) PrePaK in double interlock applications, a
minimum of 7 psi (0,5 bar) pneumatic pressure is required to super-
vise the sprinkler system. When initially filling the system with air, the
enclosure door should remain open to provide maximum air flow
to the compressor. The Model A-2 Pressure Maintenance Device,
supplied with the system, is factory set to maintain system pneu-
matic pressure at approximately 10 psi (0.7 bar).
Readjusting system pressure to approximately 10 psi (0.7 bar) is
accomplished by referring to Reliable Bulletin 251 for adjustment
procedure. The low pneumatic pressure supervisory switch is
factory set to operate between 8 and 4 psi (0.6 bar to 0.3 bar) with
decreasing pressure. Adjustment, if required, should be made ac-
cording to Potter Bulletin 5400928 included with the switch.
System Electrical Requirements
All releasing, alarm, and detection devices in the Reliable Model H
1½” (40mm) PrePaK are supervised by a Potter Model PFC-4410-
RC Releasing Control Panel. To utilize the door 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
wall of the enclosure. Note: The EOL resistors have also been relo-
cated. It is from these terminal boxes that all field wiring is connect-

one contains the 120 VAC (or 220 VAC) connections. The diagrams
illustrating this translation of terminals are shown in Figures 2 and 3.
The Reliable Model H PrePaK is delivered with five factory-installed
electrical devices. They consist of the following:
1. A low air, supervisory pressure switch, which is used to monitor
sprinkler piping.
2. A waterflow indicating pressure switch.
3. A releasing solenoid valve.
4. A 1/6 HP tank-mounted air compressor.
5. A supervised, slow-close control valve.
The factory electrical connections for these devices are illustrated
in Figure 4. For information on how to install fire detection devices to
Initiating Zones 1 and 2, refer to Figures 5 or 6. For information on
how to install output devices, i.e., alarm bells or trouble annunciators,
refer to Figure 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, Installa-
tion, Operation and Instruction of PFC-4410-RC Releasing Control
Panel.
Note:
In order for the solenoid valve to maintain Reliable’s war-
ranty it must remain sealed as it came from the factory. If
there are concerns about the valve’s internal components,
immediate replacement is recommended.
System Operation (Single Interlock)
To activate the Reliable Model H 1½” (40mm) PrePaK in a single
interlock application, an electrical detector (two detectors with cross-
zoned detection) must activate to fill the system with waters. Sub-
sequently, a sprinkler head must open to discharge water on the
fire. When a fire is detected, the releasing control panel energizes
the solenoid valve open and water flows from the supply through
the PrePaK to the system and to the waterflow indicating pressure
switch. The valve maintains its open position until the solenoid is
de-energized.
CAUTION: THE SOLENOID VALVE MUST BE MAINTAINED
OPEN TO PREVENT AUTOMATIC CLOSING OF THE MODEL H
DELUGE RISER ASSEMBLY. THE POTTER MODEL PFC-4410-
RC RELEASING CONTROL PANEL HAS A LATCHING FEATURE
FOR THIS PURPOSE.
After system shutdown and draining, the Model H Riser Assem-
bly is easily reset without special tools. Restore detection devices
by resetting or replacing any operated device. Once detection de-
vices are restored, reset the releasing control panel (Potter Manual
#5403550) and the supply pressure (see Bulletin 507, System Op-
eration).
System Operation (Double Interlock)
To activate the Reliable Model H 1½” (40mm) PrePaK in a double
interlock application, two independent events must coexist before
water flow will occur. A fire detection device must operate and the
system pressure switch must actuate by reducing the system su-
pervising air pressure (as a result of sprinkler operation). Operation
of either one of these items will only cause an alarm to annunciate,
and will not fill the sprinkler system piping with water. With coexisting
initiating signals, one electric and one pneumatic, the control panel
will now energize the solenoid valve to release water through the
PrePaK into the system piping and out the open sprinkler for com-
plete operation of the system.
When the releasing control panel energizes the solenoid valve
open, water flows from the supply through the riser into the system
and to the waterflow indicating pressure switch. The valve main-
tains its open position until the solenoid is de-energized.
CAUTION: THE SOLENOID VALVE MUST BE MAINTAINED
OPEN TO PREVENT AUTOMATIC CLOSING OF THE MODEL H
DELUGE RISER ASSEMBLY. THE POTTER MODEL PFC-4410-
RC RELEASING CONTROL PANEL HAS A LATCHING FEATURE
FOR THIS PURPOSE.
After system shutdown and draining, the Model H Riser Assem-
bly is easily reset without special tools. Restore detection devices
by resetting or replacing any operated device. Once detection de-
vices are restored, reset the releasing control panel (Potter Manual
#5403550) and the supply pressure (see Bulletin 507, System Op-
eration).
Maintenance
The Reliable Model H 1½” (40mm) PrePaK and associated equip-
ment 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 bleeder valve on the compressor tank to drain any condensate
accumulation. Refer to Bulletin 507 for information regarding main-
tenance of the solenoid valve and the manual emergency station
valve. Bulletin 251 provides information on the Model A-2 Pressure
Maintenance Device. Bulletin 806 describes the Model G Right-
Check™ Valve. Potter Manual #5403550 describes the PFC-4410-
RC Releasing Control Panel.
Resetting Single Interlock Systems
Refer to Figure 1.
1. Close the supervised valve controlling water supply to the Mod-
el H Riser Assembly and shut off the system air supply at the
Model A-2 Device.
2. Open all drain valves and the manual emergency station valve
to drain the system through the riser assembly.
3. Open any low point drain valves and vents throughout the sys-
tem, closing all drain valves and vents when draining of water
has stopped.
4. Inspect and replace any portion of the sprinkler system and de-
tection system exposed to fire conditions. Reset detectors and
PFC-4410-RC Releasing Control Panel. The PFC-4410-RC is
reset by pushing the “System Reset” button. This action will
also close (reset) the solenoid valve.
5. Reset the Model H Riser Assembly in accordance with Bulletin
507, Model H Deluge Riser Assembly Instructions for Installa-
tion, Operation, Care and Maintenance.
6. Restore the system supervising pressure to approximately 10
psi (0.7 bar) by opening the valves on the Model A-2 Pressure
Maintenance Device (refer to Bulletin 251) and adjusting the
regulator, as required.
7. Verify that the supervised control valve is open, and proper
monitoring has been restored. Also verify there is no leakage
from the automatic drain valve, thereby confirming that supply
water is not leaking into the system.

8.
Testing Detection System Without Causing
Water Flow (Single Interlock)
Refer to Figure 1.
1. Close the supervised valve controlling water supply to the Mod-
el H Riser Assembly, and note the water pressure gauge read-
ing. Also, shut off the system air at the Model A-2 Device.
2. Operate the detection system - operate a cross-zoned releas-
ing control panel by operating two detectors.
3. Operation of the detection system must result in a sudden drop
of water pressure as the solenoid valve opens. When the water
pressure gauge drops to zero, open main drain valve, bypass
drain valve and manual emergency station valve until all water
above the supervised control valve drains away.
4. Reset detection system - reverse operations performed in Step
“2” above. All detection devices must be reset before the PFC-
4410-RC Releasing Control Panel can be reset. The solenoid
valve closes when the releasing panel is reset. Close the by-
pass drain valve and manual emergency station valve.
5. Slightly open the supervised valve controlling water supply to
the Model H Riser Assembly, closing main drain valve when
water flows steadily. Open slowly, but fully, the supervised con-
trol valve and monitor it properly.
6. It is necessary to shut down the supervisory pressure supply
(ref. Step “1”) during testing; otherwise, low pressure annuncia-
tion can occur when the drain valves are opened in Step “3”.
Restore the supervisory pressure to 10 psi (0.7 bar) at this time.
Testing Detection System Without Causing
Water Flow (Double Interlock)
Refer to Figure 1.
1. Close the supervised valve controlling water supply to the Mod-
el H Riser Assembly, and note the lower water pressure gauge
reading.
2. Operate a double interlock system by operating one detector
and also venting the supervising pressure, through the inspec-
tors test station, below 4 psi (0.3 bar), to operate the low air pres-
sure switch.
3. Operation of a detector and the system pressure switch must
result in a sudden drop of water pressure as the solenoid valve
opens. When the water pressure gauge drops to zero, open
the main drain and bypass drain valves until all water above the
supervised control valve drains away.
4. Reset system by following the operation described previously in
Steps “5” through “7” of the section named “Resetting Double
Interlock Systems.” All detection devices must be reset before
the PFC-4410-RC Releasing Control Panel can be reset.
5. Open slightly the supervised valve controlling water supply to
the Model H Riser Assembly, closing the main drain valve after
water flows steadily through it. Open slowly, but fully, the control
valve and supervise it properly. Verify there is adequate water
supply pressure and proper pneumatic supervisory pressure
on the appropriate gauges. There should be no pressure
reading on the water gauge directly above the manual emer-
gency releasing station when the system is properly reset.
Resetting Double Interlock Systems
Refer to Figure 1.
1. Close the supervised valve controlling water supply to the Mod-
el H Riser Assembly and shut off the system’s air supply at the
Model A-2 Device.
2. Open all drain valves and the manual emergency station valve
to drain the system.
3. Open all the drain valves and vents at low points throughout the
system, closing them when flow of water to drain has stopped.
4. Inspect and replace any portion of the sprinkler system and
detection system exposed to fire conditions. Reset detectors.
Note: It is not possible to reset the PFC-4410-RC panel until
Step “6”, which resets the system pressure switch, has been
completed.
5. Restore the system supervising pressure to approximately 10
psi (0.7 bar) by opening valves on the Model A-2 Pressure
Maintenance Device (refer to Bulletin 251) and adjusting the
regulator, as required.
6. Verify that the bypass drain valve is closed to prevent the loss
of pneumatic supervising pressure out of the automatic drain
valve. When the supervising pressure has reached the 10 psi
(0.7 bar) setting, the low air pressure switch will automatically
reset (contacts now open).
7. With the low air pressure switch reset (Step “6”) and all detec-
tors replaced or reset (Step “4”), the PFC-4410-RC Releasing
Control Panel can be reset. Pushing the “System Reset” button
on the panel will simultaneously restore the solenoid valve to the
closed condition.
8. Restore water supply to the Model H Riser Assembly in ac-
cordance with Bulletin 507, Model H Deluge Riser Assembly
Instructions for Installation, Operation, Care, and Maintenance.
Inspection and Testing of Single Interlock
Refer to Figure 1.
1. Water supply - be sure the supervised valve controlling water
supply to the Model H Riser Assembly is open fully and prop-
erly supervised.
2. Other trimming valves - check that all pressure gauge valves
are open, and that the Model A-2 Pressure Maintenance De-
vice ¾” NPT fill valve is closed. The two ¼” NPT bypass line
valves must be fully open.
3. Check that system supervising pressure is approximately 10
psi (0.7 bar).
4. Operation test - for detection only, operate by actuation of a
keyed manual (electrical) emergency station (refer to Figure 5
for wiring instructions). Double interlock systems also require
the supervisory pressure to be discharged, through the inspec-
tors test station or other venting means, below 4 psi (0.3 bar)
before total system operation will occur.
Note: Total system operation testing will cause water flow
through the Model H Riser Assembly and into the system.
Where difficulty in performance is experienced, contact Reli-
able Technical Services before any field adjustment is to be
made.

(Single Hazard, Cross Zoned, 2 Alarm Zones
(1 Detection & 1 Low Air), 1 Waterflow Zone,
and 1 Supervisory Zone)
1. Apply power to the panel.
2. Slide the program switch down.
3. Press the FUNCTION button until the display reads “PASS-
WORD=000.”
4. To enter a password, press the SELECT button until the proper
number is displayed above the “^” symbol; then press the SET
button to move to the next digit. After entering the third number,
the display will change. (All panels are shipped with a “000”
password).
5. Press the FUNCTION button until the display reads “PRO-
GRAM ##” (the second “#” character refers to the current pro-
gram number between “0” and “24”).
6. Press the SELECT button until the display reads “PROGRAM
#9.”
7. Press the SET button.
8. The panel is completely programmed except for the custom
banner and zone messages. Slide the program switch back
up.
INPUT: 1 supervisory zone, 1 conventional detection zone, 1 low air supervisory zone, 1 waterflow zone, 1 low
air alarm zone.
OUTPUT: 1 general alarm, 1 supervisory, 1 waterflow, 1 solenoid release circuit.
OPERATION: Activation of the conventional detection zone and the low air alarm zone at the same time will operate
the solenoid release circuit and the general alarm bell.
Activation of the conventional zone only will operate the general alarm output.
Activation of the low air supervisory zone will operate the bsupervisory bell output.
Activation of the waterflow zone will operate the waterflow bell output.
Activation of the low air alarm zone will operate the supervisory bell output. It will not operate the
alarm relay.
When Zone #1 is in alarm, Output #1 will operate.
When Zone #2 is activated, Output #3 will operate.
When Zone #3 is in alarm, Output #2 will operate.
When Zone #4 is activated, Output #3 will operate. This will create a supervisory condition not an
alarm condition. The alarm relay will not operate, the supervisory relay will.
When both Zones #1 and #4 are activated at the same time, the solenoid circuit will operate.
* The Butterfly valve in the PrePaK assembly is connected to Supervisory 2 input of the Potter PFC-4410RC
Releasing/Control panel.
