General
Description
The TYCO NG-1 1000 Skid-Mounted
Nitrogen Generator is 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
membrane separation technology that
produces 98%+ nitrogen on demand
without the need for nitrogen storage.
The Nitrogen Generator can be used
to provide DPNI for single or multi-
ple zones depending on the following
factors:
• Number of systems
• Volume of the largest system
• Cumulative volume of all systems
being supplied
The generator includes an external
by-pass valve for maintenance or for
“fast fill” needs to meet the NFPA 13
30-minute fill requirement 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).
Refer to TFP1262 for more information
on TYCO Dry Air Vent (TAV-D), and to
TFP1263 for more information on TYCO
SMART Air Vent (TSV-D).

Installation
The TYCO NG-1 1000 Skid-Mounted
Nitrogen Generator must be installed
in accordance with this section.
WARNING
Do not operate the TYCO Skid-
Mounted Nitrogen Generator System
if damaged during shipment, handling
or use. Failure to do so may result in
personal injury or property 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 an 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.
Step 1: Mounting the Skid-Mounted
Nitrogen Generator
The TYCO Skid-Mounted Nitrogen
Generator is designed to be mounted
directly to the floor in the fire sprinkler
riser room as shown in Figure 1. Several
factors should be considered in choos-
ing the proper mounting location for the
nitrogen generator:
• Access to the power supply (dedi-
cated circuits as per above)
• Access to the sprinkler risers being
supplied from the nitrogen generator
• Access to a drain for the condensate
discharge line
• Clearance at the front of the unit to
open the cabinet door
• Clearance from the side of the unit to
access the power box
The skid base comes with pre-punched
holes in the skid feet for easy mount-
ing to the floor using standard anchors
as shown in Figure 2. The anchors can
be tightened through the pre-punched
access holes located at the corners of
the skid.
Step 2: Power Supply
The nitrogen generator requires two
dedicated power supply circuits
as shown in Figure 3. Both circuits
connect to the terminal blocks inside
the power supply box.
1. 2 hp compressor power supply
460 VAC/Three phase/60 Hz dedi-
cated 20 amp circuit (Standard)
208 VAC/Three phase/60 Hz dedi-
cated 20 amp circuit (Optional)
Note: When providing 208 VAC/Three
Phase/60 Hz to the control box, verify the
compressor and the motor starter have
been reconfigured for operating at 208
VAC/Two Phase/ 60 Hz.
2. Nitrogen generator power supply
120 VAC/Single phase/60 Hz dedi-
cated 20 amp circuit
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
regulator for each zone being served.
The preferred AMD is the TYCO AMD-1
(Refer to TFP1221).
Note: When both dry pipe and preaction
fire sprinkler systemsare connected to one
nitrogen generator, additional equipment
may be required if the fire sprinkler
systems operate at different supervisory
gas pressures.
• Leak Monitoring - The nitrogen gen-
erator 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
• By-pass Mode Alarm - Form C
contacts
• Nitrogen Generator Running - Form
C contacts
• Leak Monitoring - Form C contacts
• Nitrogen Supply Line Pressure -
Analog Signal
Step 4: Plumb the Condensate Drain
Line
The Skid-Mounted Nitrogen Genera-
tor will occasionally discharge a small
amount of condensate water from the
coalescing filters inside the cabinet
and the air compressor tank. It is rec-
ommended that the 1/2 in. drain con-
nection be plumbed to a floor drain or
building exterior. When plumbing to a
drain is not feasible an evaporative col-
lection 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 4.
• By-pass Mode Alarm - The nitrogen
generator is operating in the by-pass
mode which is activated when the
by-pass valve is in the “FAST FILL”
position to fast fill the fire sprinkler
system and the air supplied directly
from the air compressor has reached
a pressure of 20 psig (1,4 bar). (Flash-

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 5, perform the
following steps when taking the Nitro-
gen Generator out of service.
Step 1. Turn the power supply to the
unit off.
Step 2. Close the Inlet and Outlet Ball
Valves, and open the By-pass 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
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
retaining disc, filters screw directly into
housing.
Step 8. Remove the Water Separator
housing by pulling down on the blue
housing lock and turning the housing
counter-clockwise. Inspect the Water
Separator and clean as necessary.
Step 9. Replace the Water Separator
housing by pushing up into position
and turning the housing clockwise until
blue housing lock locks into place.
Step 10. Close the Depressurization
Ball Valve. The Nitrogen Generator can
now be placed back into service.
