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-

tained and serviced in accordance with

this section.

Before closing a ﬁre protection system

main control valve for maintenance

work on the ﬁre protection system that

it controls, permission to shut down

the affected ﬁre protection systems

must ﬁrst be obtained from the proper

authorities. All personnel who may

be affected by this decision must be

notiﬁed.

Inspection, testing, and maintenance

must be performed in accordance

with the requirements of the NFPA, and

any impairment must be immediately

corrected.

The owner is responsible for the inspec-

tion, testing, and maintenance of their

ﬁre protection system and devices in

compliance with this document, as well

as with the applicable standards of any

authorities having jurisdiction. Contact

the installing contractor or product

manufacturer with any questions.

Automatic sprinkler systems are rec-

ommended to be inspected, tested,

tion Service in accordance with local

requirements and/or national codes.

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.
