1- General description
This TOTALPAC®3integrated fire protection system by
FIREFLEX Systems Inc. consists of a preaction system trim
totally pre-assembled, pre-wired and factory tested. All
electrical and mechanical components of the system are
contained in one single unit.
Note:Skid units include the trim components only and must
be wired by the installing contractor.
The only connections required for installation are the water
supply inlet, the water discharge outlet, the main drain, the
pneumatic release inlet, the electrical supervisory and
alarm connections, as well as the AC power line for the
optional air compressor. The discharge outlet is
connected to a fixed piping network of automatic
sprinklers, in parallel to the pneumatic release piping
network (pilot line). Water is the extinguishing agent.
On system piping network and pneumatic release piping
network, closed heat sensitive automatic sprinklers are
spaced and located in accordance with recognized
installation standards in order to detect a fire. Only those
sprinklers immediately over or near to fire operate,
minimizing water damage.
Non interlock preaction system with pneumatic release
uses closed automatic sprinklers on the system piping
network, which is supervised with air pressure. A
pneumatic release piping network is installed in parallel
with the system piping network and is designed to operate
before an automatic sprinkler fuses from the system piping
network. Pneumatic release system operates first and
gives a supervisory signal.
Non interlock preaction system is designed so the deluge
valve will open when either a loss of pressure from the
pneumatic release piping network or from the system
piping network occurs. When the deluge valve opens,
water will flow into the system piping network and out of
any open automatic sprinklers and other opening on the
system.
In the event of no operation of the pneumatic release, the
system will operate as a dry system. In the event of
damage to the system piping network or an automatic
sprinkler, the deluge valve will open. Water will flow from
any open automatic sprinklers and any other opening in
the system piping network.
Note: Every TOTALPAC ®3unit is identified with its unique
serial number. This number is located on an adhesive
label inside the main door panel and is used to maintain a
record in our computerized data base. Have this serial
number handy when calling for information on your unit
(format is TOT3#### or TOTS#### for skid units).

6- Configuration description
TOTALPAC ®3 preaction system is built around the Viking
trim using straight through deluge valve model F-1
(model F-2 is the Halar ® coated version for use in
corrosive environments).
The valve is rated up to a maximum of 250 PSI WWP
(1724 kPa) and is available in the following diameters:
 1½" (40 mm)  3" (80 mm)  6" (150 mm)
 2" (50 mm)  4" (100 mm)  8" (200 mm)
TOTALPAC ®3 preaction system is supplied with groove/
groove deluge valve. Unit with flange/flange deluge valve
is also available on request.
6.1 Non interlock preaction system
Both pneumatic release piping network and system piping
network are pressurized with air or nitrogen gas. The
preaction system uses the Viking deluge valve which
opens either by the releasing of the pneumatic release
piping network, the fusing of an automatic sprinkler in the
system piping network, or anytime the handle of the
emergency release valve is pulled.
If the pneumatic release piping network releases due to
fire, damage or malfunction, the deluge valve will open but
the water will be trapped inside the system piping network
until an automatic sprinkler fuses, flowing water.
If the pneumatic release piping network does not operate,
the preaction system will operate as a dry pipe system. If
the system piping network is broken or an automatic
sprinkler fuses, the deluge valve opens, flowing water.
7- System release
7.1 Pneumatic release
Preaction system with pneumatic release requires a
pneumatic release piping network equipped with
thermostatic (rate of rise) releases, and/or fixed
temperature releases, and/or pilot heads. Release trim for
the deluge valve requires a pneumatic actuator normally
held closed by the pressure maintained in the pneumatic
release piping network and the system piping network.
In fire condition, when the pneumatic release piping
network releases, or when an automatic sprinkler fuses on
the system piping network, the deluge valve opens. If
automatic sprinklers are still closed, water will be trapped
inside the system piping network until an automatic
sprinkler fuses. If any automatic sprinkler fuses, water will
flow from the preaction system through opened sprinklers.
Automatic sprinkler must open to allow water to flow from
the preaction system.

properly (see paragraph 1.7.3 FULL FLOW TRIP TEST of
the current section).
14. Notify the AUTHORITY HAVING JURISDICTION, remote
station alarm monitors, and those in the affected area
that the system is in service.
Note: When a valve has been removed from service and is
subject to freezing or will be out of service for an extended
period of time, all water must be removed from the priming
chamber, trim piping, water supply piping and any other
trapped areas.
1.4 System Operation
1.4.1 In the SET condition
System water supply pressure enters the priming chamber
of the deluge valve (A1) through the priming line which
includes a normally open priming valve (B1), strainer (B2),
restricted orifice (B3) and spring loaded check valve (B4).
Water supply pressure is trapped in the priming chamber
of the deluge valve (A1) by spring loaded check valve (B4),
pneumatic actuator (F3), PORV (B9) (pressure operated
relief valve) and manual emergency release valve (B10).
The pressure in the priming chamber holds the deluge
valve clapper closed, keeping the outlet chamber and
system piping dry.
1.4.2 In a fire condition
When a releasing device operates from the pneumatic
release piping network (pilot line), or when an automatic
sprinkler fuses on the system piping network, the low air
supervisory switch (E4) activates and pneumatic
actuator (F3) opens.
Pressure from the priming chamber of the deluge
valve (A1) is released to the open drain manifold faster
than it is supplied through the restricted orifice (B3). The
deluge valve clapper opens to allow water to flow into the
piping network and alarm devices, causing water flow
alarms connected to the alarm pressure switch (C1) and
the optional water motor alarm (C2) to activate. When an
automatic sprinkler fuses, water will flow from the system
piping network.
When the deluge valve (A1) opens, the sensing end of the
PORV (B9) is pressurized, causing it to open. It then
continually vent the priming chamber, preventing the
closure of the deluge valve. The deluge valve can only be
reset after the system is taken out of service.
Note: If the pressure from the pneumatic release piping
network (pilot line) is lost due to mechanical damage or
malfunction of a release device, the deluge valve (A1) will
open but the water will be trapped in the system piping
network. Alarm devices (C1 and optional C2) will operate.
1.4.3 Manual operation
Anytime the handle of the manual emergency release
valve (B10) is triggered, pressure is released from the
priming chamber of the deluge valve (A1) causing deluge
valve to open. Water will flow into the system piping
network and alarm devices (C1 and optional C2) will
operate. The PORV (B9) keeps the deluge valve open.
When an automatic sprinkler fuses, water will flow from the
system piping network.
1.4.4 Supervisory condition
If an automatic sprinkler opens prior the operation of a
pneumatic release device or any time the supervisory
pressure is lost in the system piping network, the low air
pressure switch (E4) will signal a low air pressure
condition. Pressure is then released from the priming
chamber of the deluge valve (A1) causing deluge valve to
open. Alarm devices (C1 and optional C2) will operate.
Water will flow through the system piping network.

Trim Options
FM-076A-0-81C
Preaction trim options
1. Shut-off valve & sight glass
The shut-off valve & sight glass option is intended to be
used for applications where testing of the system operation
without filling the sprinkler piping network is desirable and
where it is critical that all functions of the preaction system
be tested under actual discharge conditions. Examples of
such applications are freezers, ovens, museums, data
processing and other hazards where the possibility of
water leaking from the piping system is to be avoided at all
costs.
Operation of the shut-off valve
Inspection of the system can be implemented without filling
the sprinkler piping network with water.
1. CLOSE the sprinkler piping network shut-off valve (D4);
the valve is supervised on the same circuit as the main
water supply valve (D1).
2. OPEN the main drain valve (D3).
3. Simulate the operation of the system to open the deluge
valve (A1); see annual test under section B
INSPECTION AND MAINTENANCE. Using a flashlight in the
sight glasses, verify that water flows through the sight
glass assembly (D5).
4. Once tests are completed, make sure the main drain
valve (D3) is completely CLOSED. Return the system in
service as per section B PLACING THE SYSTEM BACK IN
SERVICE.
5. Fully OPEN the shut-off valve (D4). Reset the release
control panel as per section E CONTROL BUTTONS.
Warning : Shut off valve (D4) is not available on 8"
(200 mm) system.

3. Semi and full-flanged option
When required by the user, TOTALPAC®3unit can be
provided in either a semi-flanged of full flanged
configuration.
The semi flanged option provides flanged fittings only on
the water inlet pipe (side needs to be specified at the time
of order) and on the system riser outlet. The drain
manifold is then provided with a threaded end that also
needs to have its side specified (left or right). The rest of
the fittings are the same as usual with the main
components being provided in the standard flanged/
grooved configuration.
The full flanged option is the same as above but goes a
step further with the main components being also provided
with a flanged-flanged configuration.
When provided, the face of the flanges will always be
located 6 inches from the outside face of the mounting
base or cabinet surface. On skid unit, the surface of the
flange on the outlet riser will always be 6 inches above the
dimension shown on the dimensional data of the system
ordered.

FM-076A-0-86C
1. Cabinet Air Supplies
Preaction sprinkler system using air pressure for
supervisory or releasing purposes is provided with either
internal or external supervised air supply.
WARNING Pressures other than the factory pressure
settings may affect the operation of the system.
Four (4) styles of air supplies are available for the
TOTALPAC ®3 units depending on needs or configurations.
These air supplies are all factory assembled, mounted in
the cabinet and pressure tested. Following is the
description of those options.
1.1 Air supply Style "A" (refer to figure 2)
Used only for the sprinkler piping network of preaction
systems. Air supply style "A" includes the air compressor
mounted inside the TOTALPAC ®3 cabinet with its
supervisory trim and options. Air compressor is of the
oilless piston type without reservoir and is factory piped to
the sprinkler piping system riser, all within the TOTALPAC ®3
cabinet.
A factory wired isolation switch (see figure 2 in section E
CONTROLS SECTION) is also provided in the TOTALPAC®3
cabinet, allowing powering off the air compressor while
some maintenance work on the unit is done, without
disturbing the rest of the system.
To connect non-energized AC power to the air
compressor, refer to field wiring diagram (see section F

Note : Selection of the appropriate wire size is the
responsibility of the installing contractor.
1.2 Air supply Style "B" (refer to figure 3)
Used only for the sprinkler piping network of preaction
system, when an external air supply is provided by others
(either a compressor, plant air or dry nitrogen cylinders)
and piped to the air inlet port of the unit.
Air supply style "B" provides an APMD (air pressure
maintenance device) trim, factory mounted in the
TOTALPAC ®3 cabinet. The APMD regulates and restricts
the inlet pressure. It allows an outlet pressure range from
5 PSI to 75 PSI (34 kPa to 517 kPa) ±2 PSI (14 kPa). An
internal ball check valve prevents back flow.
Warning : When air supply style "B" is selected, the air
supply should be provided and installed by the sprinkler
contractor OUTSIDE of the TOTALPAC ®3 cabinet. Air
supply is NOT provided with the unit.
1.3 Air supply Style "C" (refer to figure 4)
Used only for the pilot line release. An external air supply
has to be provided by others (compressor, plant air or dry
nitrogen cylinders) and piped to the air inlet port of the unit.
Air supply style "C" provides an APMD (air pressure
maintenance device) trim, factory mounted in the
TOTALPAC ®3 cabinet. The APMD regulates and restricts
the inlet pressure. It allows an outlet pressure range from
5 PSI to 75 PSI (34 kPa to 517 kPa) ±2 PSI (14 kPa). An
internal ball check valve prevents back flow.
Warning : When air supply style "C" is selected, the air
supply should be provided and installed by the sprinkler
contractor OUTSIDE of the TOTALPAC®3 cabinet. Air
supply is NOT provided with the unit.
1.4 Air supply Style "D" (refer to figure 5)
Mainly used with preaction system protecting refrigerated
spaces and freezers, where a special dry external air
supply unit is piped directly to the system riser inside the
freezer itself, as shown in NFPA-13. Air supply style "D"
provides only an air supervisory and shut-off trim.
Ambient temperature at the special external air supply unit
location should not exceed 104°F (40°C). Refer to NFPA
and Factory Mutual Codes & Standards for details on
refrigerated spaces applications. Air supply style "D" can
also be used when the contractor prefers to provide his
own air supply & regulation trim, mounted outside the
TOTALPAC ®3 cabinet.
Note : External air supply MUST always be restricted to
insure that the air supply cannot replace air as fast as it
escapes when an automatic sprinkler operates.
Warning : When air supply style "D" is selected, the air
supply should be provided and installed by the sprinkler
contractor OUTSIDE of the TOTALPAC ®3 cabinet. Air
supply is NOT provided with the unit.

2. Operation
2.1 Air supply Style "A" (refer to figure 2)
To apply air supply
Establish AC power for the air compressor by activating
the correspondent circuit breaker at the electrical
distribution panel. Start air compressor by activating the
compressor isolating switch (E15) located on the junction
box of the unit (see figure 2 in section E CONTROLS
SECTION).
If the air compressor motor fails to start or slows down
under load, shut the air compressor off. Check that the
supply voltage agrees with the motor nameplate.
To close air supply
Turn off the compressor isolating switch (E15) (see
figure 2 in section E CONTROLS SECTION).
To adjust air supply
The air compressor cut-off pressure switch (E2) is factory
set. This switch should not need any adjustment but if
necessary, follow the instructions below:
WARNING The adjustment screw of the cut-out/cut-in
differential pressure switch (E2) (small screw to the right)
is factory set. DO NOT CHANGE ITS SETTING. Any
unauthorized modification of this adjustment screw will
void the system warranty and may also prevent the system
from operating normally.
1. Remove the metal cover of the compressor air pressure
switch (E2).
2. To raise the cut-out pressure of the air compressor, turn
the cut-out adjustment screw (middle) half a turn
CLOCKWISE. Use the same method turning the cut-
out adjustment screw COUNTER-CLOCKWISE to lower
the air compressor cut-out pressure.

DO NOT CHANGE !
FM-072Q-0-109B
Note : Do not turn the cut-out adjustment screw (middle) all
the way down in one shot. Proceed by steps.
3. OPEN the main drain valve (D3) and let the pressure
drop until the air compressor restarts. Check pressure
reading on the system pressure gauge when the air
compressor stops again. Repeat until the desired
pressure is reached. Once all done, replace the metal
cover on the switch (E2).
2.2 Air supply Style "B" or "C" (refer to figure 3 or 4)
To apply air supply
1. Turn on upstream air supply.
2. OPEN APMD (air pressure maintenance device) input
valve (E6) by placing handle in line with valve body.
3. OPEN APMD output valve (E7) by placing handle in line
with the valve body.
4. OPEN bypass valve (E8) by placing handle in line with
valve body in order to accelerate filling of sprinkler
piping network by air pressure, while piping is initially
filled.
5. Once the piping network pressure is reached, CLOSE the
bypass valve (E8) by placing handle crossways to valve
body, and kept in this position.
Note: The bypass valve (E8) must be kept closed once the
system is filled with air.
To close air supply
1. CLOSE APMD output valve (E7) by placing handle
crossways to valve body.
2. CLOSE APMD input valve (E6) by also placing handle
crossways to the valve body.
3. Be sure bypass valve (E8) is CLOSED (handle crossways
to valve body).
To adjust air supply
1. Verify that APMD input valve (E6) and APMD output
valve (E7) are both OPEN (handle in line with the valve
body).
2. Be sure that bypass valve (E8) is CLOSED (handle
crossways to valve body) prior to performing this
operation.
3. Loosen lock nut of the APMD (E5) and turn pressure
adjustment nut clockwise to increase air pressure or
counter-clockwise to decrease pressure.
4. Tighten lock nut.
Note: Depending on site conditions, the internal filter of the
APMD may need maintenance on a regular basis. Refer to
Viking data sheet #127 for more details.
2.3 Air supply Style "D" (refer to figure 5)
To apply air supply
1. Turn on upstream air supply.

3. Maintenance and inspection
Important : Advise local authorities of the necessary work
over the fire protection equipment. In order to avoid
accidental water release, it is considered good practice to
completely close the main water supply valve (D1) while
doing maintenance work.
3.1 Air supply Style "A" (refer to figure 2)
The Style “A” air accumulator should be drained once a
year. The amount of moisture pumped into the system
and how quickly it accumulates is proportional to the
amount of humidity in the air and how long the compressor
is in operation.
To drain the air supply accumulator
At least once a year, OPEN air option drain valve (E12) until
all condensate water is drained from the air receiver.
CLOSE air option drain valve.
Safety valve pressure
A safety relief valve is provided on standard compressor
and is preset at the factory. Do not adjust or exceed
safety relief pressure other than those preset at the
factory.
WARNING The relief valve and outlet pipe of the air
compressor may become very hot during normal
operation. Do not touch the valve, compressor heads or
outlet piping until the compressor has been turned off and
allowed to cool.
WARNING Do not unscrew relief valve head entirely off
while the compressor is operating. Ejection of valve parts
could cause severe injury.
3.2 Air supply Style "B" or C" (refer to figure 3 or 4)
The Viking Model D-2 APMD (air pressure maintenance
device) (E5) is a pressure regulator that automatically
reduces the supply air pressure to a pre-set requirement
when connected to a constantly maintained air supply
(plant air, external tanked air compressor or dry nitrogen
tank).
Determine the appropriate pressure to be maintained in the
system. Refer to table 2 or table 3 of the current section.
If adjustment is necessary, refer to paragraph 2.2 of the
current section.
To clean APMD (air pressure maintenance device)
1. Turn off external air supply.
2. CLOSE APMD output valve (E7) by placing handle
crossways to valve body.
3. CLOSE APMD input valve (E6) by also placing handle
crossways to the valve body.
NOTE : Never disconnect or disassemble the APMD (E5)
without closing those isolation valves.
4. Carefully loosen the union between the outlet of
APMD (E5) and the outlet isolation valve (E7) to relieve
pressure.
5. Remove and clean air pressure maintenance device
APMD (E5) filter. If admission filter is blocked, replace
with filter kit (part #03007 A).
Refer to Viking data sheet #127 for additional details.
3.3 Air supply Style "D" (refer to figure 5)
The air or nitrogen supply provided must be continuous,
clean, dry and oil free.
