1.4 GENERAL DESCRIPTION
The F IRE F LEX
®
N
2
Blast
®
integrates the same type of preaction automatic sprinklers system as found in the renowned F IRE F LEX Systems T OTAL P AC
®
3 using top quality Viking Corporation components and the deluge valve model F-1.
The Nitrogen generator is a N
2
Blast
®
Type 1 FPS-250 or FPS-750 system, made by South-Tek Systems.
The N
2
Blast
®
FPS-250 and FPS-750 designed & manufactured by South-Tek Systems provide an economical, precise means of generating high purity
Nitrogen. Since air is comprised of ~79% N
2
we simply and cost-effectively separate the N
2
from the air.
Nitrogen is an inert gas (non-combustible) and widely used in thousands of industries along with Fire
Protection Systems. The N
2
is “generated” by means of the air compressor pushing air into the simple, safe membrane element, which in turn mechanically separates N
2
molecules from other molecules found within air.
The F IRE F LEX

1.7 RELEASING
Release trim for the double interlocked preaction system with electric / pneumatic release utilizes a normally closed solenoid valve (F1) controlled by the
Viking VFR-400 integrated control panel with a compatible detection system (supplied by others) and a pneumatic actuator 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 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.

2. Corrosion Inhibiting System
2.1 NITROGEN GENERATOR
The N
2
Blast
®
Corrosion Inhibiting System produces 98%+ pure Nitrogen on demand and introduces it to the preaction
Fire Protection System. In doing so, Oxygen and moisture are displaced from the piping through the AutoPurge
System™. The N
2
Blast
®
Nitrogen Generation System effectively inhibits Electrochemical, Galvanic and
Microbiologically Influenced Corrosion (MIC), as well as freezeups and ice plugs.
All personnel involved with installation, operations, and maintenance of the N
2
Blast
®
must follow safe working practices, OHSA, and local health/safety code regulations during the installation, operation, and maintenance of the unit.

Blast
®
Nitrogen generator
South-Tek Systems utilizes Membrane technology in the N2-Blast® Corrosion Inhibiting Systems in order to efficiently separate Nitrogen molecules from the air we breathe. Membrane technology, used in our smaller applications, has a simple air flow design, is wallmounted and easy to service. PSA technology is more cost effective and energy efficient in larger Fire
Protection Systems, those requiring more Nitrogen to compensate for the NFPA “acceptable leak rate”.
2.5 BlastOff
™
Leak Detection System
Unless the leak rate is catastrophic, the supervisory low pressure alarm on the FPS will not activate. Minor leaks cause the air compressor and N
2
Blast
® to run excessively in order to maintain supervisory pressure.
The unnecessary additional run-time decreases the lifespan of the equipment. The Patent Pending
BlastOff
™
Leak Detection System is designed to detect significant leaks before they compromise the Fire protection System and the Nitrogen Generation System.
It has an internal audible alarm and dry contact for wiring into the Building Monitoring System (BMS) and will also alarm if the air compressor or the N
2
-Blast
® is not working properly.
2.6 N
2
Blast
®
AutoPurge System™
High purity Nitrogen must be equally distributed throughout the entire sprinkler piping system in order to effectively inhibit corrosion. The Patent Pending
AutoPurge System™provides a low volume, constant purge of Nitrogen within sprinkler piping. The rate in which gas is evacuated from the sprinkler piping is within NFPA guidelines and allows breathing to occur.
The AutoPurge System™ also assists in drying out the residual water from a hydrotest. Computational Fluid
Dynamics modeling proves that this is the most effective way to ensure that high purity Nitrogen reaches all branches within the sprinkler piping. Install one AutoPurge System™ per system at a high point .

3. PREACTION SYSTEM
3.1 DESCRIPTION
The preaction system in the F IRE F LEX
®
N
2
Blast
®
integrated fire protection system by F IRE F LEX 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 detection and alarm connections, as well as the
AC power line(s). 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 F IRE F LEX
®
N
2
Blast
®®
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 (1724 kPa) working water pressure max. and is available in the following diameters: f
1½" (40 mm) f 4" (100 mm) f
2" (50 mm) f
3" (80 mm)
3.3 RELEASE
Release trim for the electric pneumatic operated double interlocked preaction system utilizes a normally closed solenoid valve controlled by the Viking
VFR-400 integrated control panel with a compatible detection system (supplied by others) and a pneumatic actuator (F3) normally held closed by supervisory air pressure maintained in the sprinkler piping.
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.

5.3 OPERATION
5.3.1 Air supply Style "A"
See figure 5.3.
To apply air pressure:
Establish AC power for the air compressor by activating the correspondent circuit breaker at the electrical distribution panel. Close the air inlet drain valve . Start compressor by activating the compressor isolating switch (E15) located within the unit (see figure 4.4).
If the air compressor motor fails to start or slows down under load, shut the compressor off. Check that the supply voltage agrees with the motor nameplate.
To close the air supply:
Turn off the compressor isolating switch (see figure 4.4).
To adjust system air pressure (air compressor switch):
WARNING ! The cut-out/cut-in differential switch adjustment screw (small screw to the right) is factory set. DO NOT
CHANGE ITS SETTING. Any unauthorized modification of this setscrew adjustment will void the system warranty and may also prevent the system from operating normally.
The air compressor cut-off pressure switch (E2) (shown in figure 5.1 with its cover removed) has its air compressor cut-out adjustment screw (middle screw) factory set. This switch should not need any adjustment but if necessary, follow the instructions below:
1. Remove the cover of the air compressor cut-off pressure switch (E2) .
2. To raise the cut-out pressure of the air compressor, turn the cut-out adjustment screw (middle screw) half a turn CLOCKWISE.
3. Open the main drain valve (D3) and let the pressure drop until the air compressor (E1) restarts. Check pressure reading on the system pressure gauge (E3) when the air compressor stops. Repeat until the desired pressure is reached (refer to table 5). Once all is done, replace the cover on the switch (E2) .
Note: Do not turn the cut-out adjustment screw (middle screw) all the way down in one shot. Proceed by steps. Use the same method turning the cut-out adjustment screw
COUNTER-CLOCKWISE to lower the air compressor cut-out pressure.
Figure 5. - Front view of the air compressor cut-off pressure switch
Turn clockwise to increase both cut-out and cut-in pressure adjustment
Factory set
DO NOT CHANGE !
FM-072Q-0-109B
5.3.2 Air supply Style "B"
See figure 5.4.
To apply air pressure:
Turn on upstream air supply. If the unit is equipped with the optional dehydrator (refer to section 5.5), close the air inlet drain valve (E12) and open the air shut-off valve (E14) .
Open APMD (E5) input valve (E6) by placing handle in line with valve body then open APMD (E5) output valve (E7) by placing handle in line with the valve body.
In order to accelerate filling of sprinkler piping by air pressure, bypass valve (E8) can be opened by placing handle in line with valve body while piping is initially filled by the air compressor. This valve (E8) must then be closed (handle crossways to valve body) and kept in this position once the system is filled with air.
To close the air supply:
Close APMD output valve by placing handle crossways to valve body then close APMD (E5) input valve (E6) by also placing handle crossways to the valve body. Be sure bypass valve is closed
(handle crossways to valve body).
To adjust system air pressure:
Be sure APMD (E5) input valve and output valve (E7) are both open (handle in line with the valve body), and bypass valve is closed (handle crossways to valve body) prior to performing this operation. Loosen lock nut of the DMPA (E5) and turn pressure adjustment nut clockwise to increase air pressure or counter-clockwise to decrease pressure.
Tighten lock nut.
Note: Depending on site conditions, the internal filter of the APMD (E5) may need maintenance on a regular basis. Refer to Viking Data Sheet #127 for more details.

5.4 MAINTENANCE AND INSPECTION
5.4.1 Air supply style "A"
To close the air supply:
This procedure requires turning OFF the air compressor's
AC power by switching off the compressor isolating switch (E15) located within the unit before servicing (see figure 4.4).
Note: The air compressor motor is equipped with thermal protectors that reset automatically. These thermal protectors will stop the motor in case it overheats and can automatically start the motor when they reset.
Compressor's air inlet filter:
Intake filters are standard on most compressors and will provide adequate filtration for most applications. Check filters periodically and replace when necessary. Initial inspection is suggested at 500 hours, and then the user should determine the frequency. Most problems can be prevented by keeping filters clean. Dirty filters decrease compressor performance and can decrease compressor service life.
Maintain a clean air filter cartridge to insure best flow and performance. The location and the quality of the air being ingested indicate the frequency for inspection and replacement. A dirty filter restricts air flow, causes the pump to run hotter and results in longer operating cycles.

Nitrogen generator Owner’s Manual for instructions.
To drain the air supply accumulator (E13):
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.
At least once a year, open air inlet drain valve (E12) until all condensate water is drained from the air receiver. Close air option drain valve.
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.
A safety relief valve is provided on standard compressors and is preset at the factory. Do not exceed or adjust safety relief pressures other than those preset at the factory.
WARNING Do not unscrew relief valve head entirely off while the compressor is operating. Ejection of valve parts could cause severe injury.

5.4.2 Air supply Style "B"
See figure 5.4.
The Viking model D-2 air pressure maintenance device
(APMD) (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).
Features:
•
Replaceable air inlet filter
•
Outlet pressure range is 5 to 75 psi (
±
2 psi) (0.345 to 5.17 bar). Air pressure setting can be readjusted after installation (refer to chapter 5.3.2 TO ADJUST
SYSTEM AIR PRESSURE for air supply Style "B").
•
•
Ball check to prevent back flow
Restriction orifice 1/16" (1,59mm) to prevent rapid re- pressurization of a system. The Viking model D-
2 APMD (E5) regulates and restricts air flow.
•
The air or nitrogen supply provided to the
APMD (E5) must be continuous, clean, dry and oil free.
•
Bypass piping is provided to allow initial pressurization of system piping more rapidly than the restricted air flow through the APMD (E5) will allow.
•
Determine the appropriate pressure to be maintained in the system (refer to table 5).
The APMD (E5) should be checked after installation or repair and adjusted as required for correct pressure reading (refer to chapter 5.3.2 TO ADJUST SYSTEM AIR
PRESSURE). The filter should also be inspected and replaced or cleaned as required.
To clean the APMD (E5): compressor's power.
2. Do not disconnect or disassemble the APMD (E5) without closing the outlet (E7) and inlet (E6) isolation valves. System air pressure will be trapped between the outlet of the APMD (E5) and the downstream control valve. Relieve pressure before proceeding with disassembly.
3. Carefully loosen the union between the outlet of
APMD (E5) and the outlet isolation valve to relieve pressure.
4. Remove and clean APMD (E5) filter. If admission filter is blocked, replace with filter kit (part # 03007
A).
Refer to Viking Technical Data Sheet #127 for additional details.
To close the air supply:
Close APMD (E5) output isolation valve (E7) by placing handle crossways to the valve body. Make sure the
APMD (E5) input valve (E6) is open (handle in line with valve body) and the bypass valve (E8) is closed (handle crossways to valve body).
