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
membrane 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) 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).
System Assembly
The TYCO Nitrogen Generator unit
includes the following components:
• Steel enclosure cabinet with mem-
brane type nitrogen generator (no
nitrogen gas storage) and manual
bypass
• Power supply:
120 VAC/Single phase/60Hz
(230 VAC/Single phase/50Hz)
• Single point nitrogen/air discharge –
1/2 in. NPT
• Hour Run Meter
• Cycle Counter
System Status
The TYCO Nitrogen Generator includes
the following system status indicators:
• Bypass Mode Alarm Indicator -
Nitrogen generator is in the By-Pass
mode (flashing indicator). See Fig-
ure 4.
• Leak Monitoring Alarm - Nitrogen
generator is running excessively
(audible signal).
System Input/Output
Signals
The TYCO Nitrogen Generator includes
the following monitoring outputs:
Digital Outputs
• Power On/Off
• Bypass Mode Alarm
• Nitrogen Generator Running
• Leak Monitoring
Analog Outputs
• Nitrogen Supply Line Pressure
Support Equipment
The Nitrogen Generator is designed to
be used in conjunction with the TYCO
AMD-1 Air Maintenance Device, the
TYCO Handheld Gas Analyzer (THGA),
and the Riser-mounted TYCO Dry Air
Vent (TAV-D), or TYCO Dry SMART
Vent (TSV-D), as part of the com-
plete Dry Pipe Nitrogen Inerting (DPNI)
system. Refer to TFP1267 for more
information on the TYCO Handheld
Gas Analyzer.
The TYCO Nitrogen Generator can
be used with the following optional
equipment:
• TYCO Model TSGA SMART Gas
Analyzer - one for each nitrogen
generator is recommended. Refer to
TFP1270 Model TSGA SMART Gas
Analyzer for more information.
• TYCO Model TILD In-Line Corro-
sion Detector - monitoring at least
one for each sprinkler system is rec-
ommended. Refer to Technical Data
Sheet TFP1261 TYCO Model TILD
In-Line Corrosion Detector for more
information.
TYCO NG1
Compressors
The TYCO NG1 Compressors are
paired with the TYCO NG-1 1150,
NG-1 1500, NG-1 2000, and NG-1
3000 Nitrogen Generator in facilitating
the Dry Pipe Nitrogen Inerting (DPNI)
process in dry and preaction fire sprin-
kler systems as well as Wet Pipe Nitro-
gen Inerting (WPNI) process in wet pipe
sprinkler systems. The air compressors
