1.6 CONFIGURATION
Configuration for FIREFLEX®DUAL:
•Engineered NOVEC 1230 single cylinder with electric
release
•Double interlocked preaction with electric / pneumatic
release
1.7 RELEASING
1.7.1 Electric releasing conditions
The electric releasing condition is needed by an approved
releasing control panel in order to operate the electric
actuator (C) of the NOVEC 1230 and the solenoid
valve (F1)of the preaction system. It can be achieved as
the following:
a) Single zone detection activated by either Zone 1 or
Zone 2.
b) Cross zone detection activated by both Zone 1 and
Zone 2.
c) Manual pull station activated.
1.7.2NOVEC 1230 electric release
Electric release is achieved with an electric actuator (C)
installed on the discharge valve (B) of the cylinder (A).
When the releasing conditions are fulfilled, a 24Vdc source
is applied to the electric actuator (C) thereby venting the
pressure on top of the discharge valve (B) thus allowing
the extinguishing agent NOVEC 1230 to be discharged
through the piping and nozzles.
1.7.3Double interlocked preaction electric release
Release trim for the double interlocked preaction system
with electric / pneumatic release utilizes a normally closed
solenoid valve (F1) controlled by control panel listed for
releasing with a compatible detection system, and a
pneumatic actuator (F3) normally held closed by
supervisory air pressure maintained in the sprinkler piping.
In fire condition, when the detection condition is fulfilled,
the control panel energizes the solenoid valve (F1) and an
open sprinkler releases the supervisory air pressure from
the sprinkler piping. Both the electric detection condition
and supervisory pressure relieved fromthesprinklerpiping
are necessary before the deluge valve (A1) will open and
fill the sprinkler piping with water. Water will flow from any
opened sprinklers in the system piping.

2. CLEAN EXTINGUISHING AGENT
2.1 AGENT
The clean extinguishing agent used in FIREFLEX®DUAL total
flooding system is NOVEC 1230.
Note: The term NOVEC 1230 employed throughout this
manual refers to the extinguishing agent Dodecafluoro-2-
methylpentan-3-one known as SEVO 1230 Fire
Protection Fluid (also known as FK-5-1-12, 3M™
NOVEC™ 1230 Fire Protection Fluid, C6-F-ketone)
produced by 3M™.
2.2 DESCRIPTION
NOVEC 1230 is a colorless fluid. It is stored as a pressurized
liquid and injected into a room, area, or compartment that has
the structural integrity to retain the agent that has been
discharged.
NOVEC 1230 is dispensed as an odorless, electrically non-
conductive vapor. It leaves no residue.
NOVEC 1230 is a clean, efficient fire-extinguishing agent that
can be used on Class A, B, or C fires. It is a very stable, inert
and electrically non-conductive gas. Its primary use is for
energized electric equipment fire containment and preventing
reigniting.
2.3 ENVIRONMENTAL
NOVEC 1230 does not contribute to depletion of the
stratospheric ozone layer. NOVEC 1230 has an atmospheric
lifetime of 0.014 years. Its global warming potential is 1.
2.4 SAFETY CONSIDERATIONS
2.4.1 TOXICITY
The table 2.1 identifies the toxicological data on
NOVEC 1230 and compares this with HALON 1301.
Table 2.1 - Toxicological data
NOVEC 1230 HALON 1301
No Observed
Adverse Effect Level
(NOAEL) 10% 5.0%
Low Observed
Adverse Effect Level
(LOAEL) 10% 7.5%
Acute Exposure
LC50 (4 hour rate -
ppm) 100,000 800,000
Design Concentration
(minimum)
4.2% 4.3%
2.4.2 NOISE
Discharge of a NOVEC 1230 system can cause noise loud
enough to be startling but ordinarily insufficient to cause
traumatic injury.
2.4.3 TURBULENCE
High velocity discharge from nozzles may be sufficient to
dislodge substantial objects directly in the path of the
discharge. General turbulence in the enclosure may be
sufficient to move light objects, unsecured paper, etc.
Ceiling tiles in the vicinity of the nozzles should be clipped
in place to prevent them from being dislodged during the
discharge.
2.4.4 COOLING
Direct contact with vaporizing liquid NOVEC 1230 will have
a strong chilling effect on objects and can cause frostbite
burns to the skin. The liquid phase vaporizes rapidly when
mixed with air and thus limits the hazard to the immediate
vicinity of the discharge nozzle.
2.4.5 VISIBILITY
Upon discharge reduced visibility will be evident,
especially in humid atmospheres, as a result of the
condensations of vapor. The period of reduced visibility will
normally be brief.
2.4.6 PRESSURE
The discharge nozzle is between
73 Psi and 290 Psi (5 bar and 20 bar).

3. PREACTION SYSTEM
3.1 DESCRIPTION
The preaction system in the FIREFLEX®DUAL integrated 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.
The only connections required for installation are the water
supply inlet, water discharge outlet, main drain, the electrical
devices and alarm connections to an approved releasing
control panel. The discharge outlet is connected to a fixed
piping system of automatic sprinklers. Water is the
extinguishing agent.
The sprinklers network is supervised with compressed air or
gas. If the sprinklers piping or sprinkler is broken, the deluge
valve will not open.
3.2 CONFIGURATION
The FIREFLEX®DUAL preaction system is built around the
Viking trim using deluge valve model F-1.
The valve is rated up to a maximum of 250 psi (17.2 bar)
working water pressure max. and is available in the following
diameters:
•2" (50 mm)
•3" (80 mm)
FIREFLEX®DUAL preaction system is supplied with flange–
groove deluge valve.
3.3 RELEASE
Release trim for the electric / pneumatic operated double
interlocked preaction system utilizes a normally closed
solenoid valve (F1) controlled by an approved release
control panel with a compatible detection system, and a
pneumatic actuator (F3) normally held closed by
supervisory air pressure maintained in the sprinkler piping.
The FIREFLEX®DUAL system utilizes a detection system,
the same as clean agent.
In fire condition, the release control panel energizes the
solenoid valve (F1) and an open sprinkler releases the
supervisory air pressure from the sprinkler piping. Both
the electric detection condition and supervisory pressure
relieved from the sprinkler piping are necessary before the
deluge valve (A1) will open and fill the sprinkler piping with
water. Water will flow from any opened sprinklers in the
system piping.
Note: If the detection system does not operate
properly, the deluge valve (A1) will not open.
To prevent false discharge, if the detection system
operates alone due to fire, damage or malfunction, the
deluge valve (A1) will not open. If the sprinkler piping is
damaged or a sprinkler is broken or fused, the deluge
valve (A1) will not open either.

5. PREACTION AIR SUPPLIES
The sprinklers network of the preaction system uses air
pressure for supervisory purposes. The air supply can be
provided with either internal or external supervised air
supplies.
Two (2) styles of air supplies are available for the
FIREFLEX®DUAL unit depending on needs or
configurations. These air supplies are all factory assembled,
mounted in the cabinet and pressure tested. They are all
located in the top part of the cabinet, hung on mounting rails
above the valve trim. Here is the description of those
options:
♦Air supply Style "A"
See figure 5.3.
Used only for the sprinkler piping network of the preaction
system. Air supply Style "A" includes the air compressor
mounted inside the FIREFLEX®DUAL cabinet with its
supervisory trim and options. Compressor is factory piped
to the sprinkler piping system riser. It is available in three (3)
sizes:

1/6HP

1/3HP

1/2HP
All the above air compressors are oiless piston type without
reservoir and have open, single phase motor with internal
thermal protection and supply voltage of 120Vac, 60Hz or
220Vac, 50/60Hz.
♦Air supply Style "B"
See figure 5.4.
Used only for the sprinkler piping network of the 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 air pressure maintenance device (APMD) (E5)
trim, factory mounted in the FIREFLEX®DUAL cabinet.
Note: When air supplies Style "B" is selected, the air
supply should be provided andinstalled by the sprinkler
contractor OUTSIDE of the FIREFLEX®DUAL cabinet.
It IS NOT provided with the unit.
5.1 AIR SUPPLY DESIGN AND SELECTION
The air supply compressor should be sized to automatically
establish the total required air pressure in 30 minutes.
External air supply should be provided with an air pressure
maintenance device (air supply Style "B") to regulate and
restrict the flow of supervisory air into the sprinkler system
piping.
WARNING ! Pressures other than the factory pressure
settings may affect the operation of the system.
Note: Selection of the proper air compressor size is the
responsibility of the installing contractor.

5.2 Air compressor AC power connection
(Air supply Style "A" only)
The motor must be protected against short circuit, overload
and excessive temperature rise. Fuses, motor protective
switches and thermal protective switches provide the
necessary protection in these circumstances.
Fuses only serve as a short circuit protection of the motor
(wiring fault), not as protection against overload. Those are
provided and wired by the electrical contractor.
An isolation switch (E15) is also provided in the
FIREFLEX®DUAL cabinet (see figure 6.2) and is factory
wired, allowing powering off the air compressor while some
maintenance work on the unit is done, without disturbing the
rest of the system.
Connect non-energized AC power to the air compressor
input circuit (see figure 5.1).
