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). 

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
