General
Description
The TYCO NG-1 1150, NG-1 1500, NG-1
2000, and NG-1 3000 Stand-Alone
Nitrogen Generators are designed to
facilitate the Dry Pipe Nitrogen Inerting
(DPNI) process for controlling oxygen
corrosion in dry and preaction fire
sprinkler systems, and provide super-
visory maintenance gas. Designed for
plug and play performance in a typical
dry or preaction fire sprinkler system,
the nitrogen generator utilizes mem-
brane separation technology that
produces 98%+ nitrogen on demand
without the need for nitrogen storage.
The Nitrogen Generator is an on-site
nitrogen generation system that
is designed to be installed in-line
between the compressed air supply
and the sprinkler system riser(s). The
system provides DPNI for single or mul-
tiple zones depending on:
• the number of systems
• the volume of the largest system
• the cumulative volume of all systems
being supplied
The generator includes an external
bypass valve for maintenance or for fast
fill needs to meet the NATIONAL FIRE
PROTECTION AGENCY (NFPA) stan-
dard NFPA 13 30-minute fill require-
ment for dry pipe and preaction fire
protection systems.
The Nitrogen Generator is designed
to nitrogen inert all of the zones being
served within 14 days. Thereafter, it
will continue to automatically provide
supervisory nitrogen gas sufficient for
pressure maintenance of the fire sprin-
kler system(s).
The Nitrogen Generator facilitates
the patented fill and purge breathing
process in the fire sprinkler system
when paired with an oxygen removal
vent installed on the sprinkler riser such
as the TYCO Manual Air Vent (TAV-D)
or the TYCO Dry SMART Vent (TSV-D).

Installation
The TYCO NG-1 1150, NG-1 1500, NG-1
2000, and NG-1 3000 Stand-Alone
Nitrogen Generators must be installed
in accordance with this section.
WARNING
Do not operate the TYCO Nitrogen
Generator if damaged during ship-
ment, handling or use. Failure to do so
may result in personal injury or prop-
erty damage.
Operation of the nitrogen membrane
above the rated design pressure could
be hazardous. Do not connect the
nitrogen generation equipment to com-
pressed air sources that can exceed
the maximum rated pressure without
installing pressure controls and safety
relief devices in the compressed air
supply line.
Specific procedures must be devel-
oped for maintenance and servicing
of the equipment where the nitrogen
membrane is located. Appropriate
labels must be continuously displayed
in all areas where personnel might be
exposed to a nitrogen atmosphere
under normal and abnormal conditions.
Nitrogen is nontoxic and largely inert.
Rapid release of nitrogen gas into an
enclosed space displaces the oxygen
and can cause an asphyxiation hazard.
CAUTION
Do not install the TYCO Nitrogen Gen-
erator or Air Compressor Package in
an area where ammonia, sulfur dioxide,
hydrogen sulfide, mercaptans, chlo-
rides, chlorine, oxides of nitrogen, acid
fumes, solvent vent vapors, and ozone
vapors or similar contaminates exist.
The equipment can be damaged by
ammonia and other vapors shortening
membrane life.
NG-1 Nitrogen Generators
Step 1: Mounting the Stand-Alone
Nitrogen Generator
The TYCO Stand-Alone Nitrogen Gen-
erator is designed to be mounted
directly to the floor and/or the wall at
the installation location. Several factors
should be considered in choosing the
proper mounting location for the nitro-
gen generator:
• Access to the power supply (dedi-
cated circuit)
• Access to the air source supplied to
the nitrogen generator
• Access to the sprinkler riser being
supplied from the nitrogen generator
• Access to drain for the condensate
discharge line
• Clearance at the front of the unit to
open cabinet door
• Clearance around ventilation vents
on side and bottom for proper cabi-
net ventilation
• When floor mounting the cabinet,
ensure floor is flat and level
• If wall mounting the cabinet, ensure
the wall is capable of supporting the
weight of the generator cabinet
The cabinet includes pre-punched
holes in the feet for floor mounting and
holes in the back panel for wall mount-
ing using standard anchors.
Step 2: Power Supply
The Nitrogen Generator requires a ded-
icated power supply that connects to
the terminal blocks in the nitrogen gen-
erator cabinet. See Figure 2A or 2B as
applicable.
Step 3. Plumb the Nitrogen/Air
Supply Line
The nitrogen/air discharge plumb-
ing from the nitrogen generator is to
be connected directly to the sprinkler
system valve trim using a minimum
of 1/2 in. to 1 in. black steel, galva-
nized steel or copper piping. The size
of the nitrogen/air supply line is to be
based on the length of pipe between
the nitrogen generator and the fire
sprinkler systems along with the total
volume of the fire sprinkler systems
being supplied. The nitrogen genera-
tor requires an in-line Air Maintenance
Device (AMD) that is equipped with an
on-board field adjustable pressure reg-
ulator for each zone being served. The
preferred AMD is the TYCO AMD-1.
Refer to technical datasheet TFP1221.
Note: When both dry pipe and preaction
fire sprinkler systems are connected to
one nitrogen generator, additional equip-
ment may be required if the fire sprinkler
systems operate at different supervisory gas
pressures.
Step 4: Plumb the Condensate Drain
Line
The Stand-Alone Nitrogen Genera-
tor will occasionally discharge a small
amount of condensate water from the
coalescing filters inside the cabinet. It
is recommended that the 1/4 in. drain
connection be plumbed to a floor drain
or building exterior. When plumbing to
a drain is not feasible an evaporative
collection chamber can be used.
Step 5: System Signals and Monitor-
ing (where used)
The nitrogen generator cabinet has
two system signals and five outputs
that can be monitored by the facility’s
BMS or fire alarm system as shown in
Figure 2A or 2B as applicable.
• Bypass Alarm - The nitrogen gener-
ator is operating in the bypass mode
which is activated when the bypass
valve is in the fast fill position to fast
fill the fire sprinkler system and the
air supplied directly from the air com-
pressor has reached a pressure of 20
psig (1,4 bar). (Flashing amber light)
• Leak Monitor - The nitrogen gener-
ator is equipped with a leak moni-
tor audible signal which is activated
when the nitrogen generator runs
excessively. (Audible signal)
The nitrogen generator cabinet includes
system monitoring signals which can
be monitored through a building moni-
toring system, if desired:
• Nitrogen Generator Running - Form
C contacts
• Bypass Mode Alarm - Form C
contacts
• Nitrogen Generator Power Monitor-
ing - Form C contacts
• Leak Monitoring - Form C contacts
• Nitrogen System Supply Line Pres-
sure - Analog Signal
NG1 Compressors
Step 1. Mounting the Air Compressor
The simplex air compressors are
designed to be mounted directly to
the floor in the fire sprinkler riser room.
Several factors should be considered in
choosing the proper mounting location
for the air compressors:
• Access to the appropriate power
supply (see Step 2 for power circuit
requirements per compressor sizes)
• Access to the nitrogen generator
inlet 1/2 in. supply line
• Access to a drain for the condensate
discharge line
• Clearance to access air compressor
for servicing

The air compressors come with pre-
punched holes in the feet for easy
mounting to the floor using standard
anchors.
Note: Vibration pads (supplied) must be
installed under the feet of the air compressor
to ensure warranty of the air compressor.
Step 2. Power Supply
NOTICE
It is recommended that a service dis-
connect be provided adjacent to the air
compressor.
The air compressors require a dedi-
cated power supply that is terminated
in the power supply box on the air com-
pressor as shown in Figure 3A, 3B, or
3C as applicable. Verify the voltage
of the power supply available for the
air compressor is compatible with
the voltage requirements of the air
compressor.
NOTICE
With the TNGC-1500/2000 and the
TNGC-3000, verify that the compres-
sor and motor starter are configured
for operating at 208 VAC/3 phase
when providing 208 VAC/3 phase to
the control box.
Step 3: Plumb the Air Supply Line
For compressors in the Americas, the
air discharge plumbing from the air
compressor is to be connected to the
inlet of the nitrogen generator using
1/2 in. black steel, galvanized steel or
copper lines. For compressors in EMEA
and APAC, the air discharge plumb-
ing should first be connected to the
WSD-25 water separator which then is
to be connected to the inlet of the nitro-
gen generator.
Step 4: Plumb the Condensate
Drain Line
The TYCO oil-less air compressor will
discharge condensate water from the
air receiver tank. It is recommended
that the 1/4 in. drain connection be
plumbed to a floor drain or building
exterior. When plumbing to a drain is
not feasible an evaporative collection
chamber can be used.
Note: Ensure that the receiver tank auto-
drain is connected to an un-switched power
source: 120 VAC for Americas, 230 VAC for
EMEA and APAC.
Note: The Low Oil Level Sensor on the air
compressor automatically shuts down air
compressor until the proper oil level has
been restored. Care and

Maintenance of the Nitrogen
Generator
The nitrogen generator cabinet con-
tains three separate cartridge filters.
It is recommended that each of the
filter cartridges be replaced as part of
an annual preventative maintenance
program. In some environments it may
be necessary to replace filters more
frequently. When maintained properly
the nitrogen separation membrane will
provide up to 20 years of service life.
Filter Replacement Procedure
With reference to Figure 4, perform
the following steps when replacing the
cartridge filters located in the Filter
Housing.
Step 1. Turn the power supply to the
unit off.
Step 2. Close the Inlet and Outlet Ball
Valves, and open the Bypass Ball Valve.
Step 3. Depressurize the nitrogen gen-
erator internal inlet piping by slowly
opening the Depressurization Ball
Valve in the cabinet to the left of the
filter housing.
Step 4. Remove the filter housing by
pulling down on the blue housing lock
and turning the filter housing count-
er-clock wise.
Step 5. Once the filter housing has
been removed, the filter cartridge
inside is removed by first unscrewing
the black retaining disc at the base of
the cartridge and then pulling down on
the cartridge. Discard the old filter car-
tridge and replace it with the appropri-
ately marked filter cartridge from the
filter replacement kit by pushing up
so that it fits snugly onto the receiving
cylinder in the upper part of the filter
housing. Hand tighten the black retain-
ing disc back onto the central metal
threaded rod.
Step 6. Replace the filter housing by
pushing up into position and turning the
housing clockwise until blue housing
lock locks into place.
Step 7. Repeat Step 4 through Step 6
for each additional filter.
Note: Filters 2 & 3 do not have a black retain-
ing disc, filters screw directly into housing.
