Electrical Requirements
The N2-Blast
®
FPS-900-RS requires 120VAC / 50-60hz /
1ph and draws < 8A. A 240VAC option is also available. It has
a built-in 20A over-current protection device and comes with
a standard 3-prong US power cord for the electrical connec-
tion (unless otherwise specified). It comes with UL 508A ICP
certification, and the electrical schematics are available upon
request.
Site Specifications
Unless designed otherwise, install in a nonhazardous in-
door location with temperatures between 40-100°F (4°- 38°C).
For ease of maintenance, troubleshooting, and minimizing
pressure drop, install the equipment in the same area. Leave
enough space around the generator and other equipment for
routine maintenance.
Key Features
Air Compressor
An oil-less internal air compressor has an engineered
dampening system reducing vibration and noise throughout
the cabinet. The air compressor has a pre-filter to catch small
particulates that can cause damage. The recommended re-
placement for the pre-filter is 1000 run hours or 1-year, which -
ever comes first. Dirtier environments may need more frequent
changes. Consult with the supplier for a different filter mainte -
nance schedule if installing in a dirty environment.
Air Filters
The generator has an air inlet pre-filters and two filters be -
tween the compressed air and O
2
separation beds - the par-
ticulate and coalescing. The 5-micron particulate filter catches
the bulk particles, and the 0.1 micron coalescing catches the
remaining smaller particles. Both filters feature an auto-drain
that drains any water buildup within the filter housing. These
drain lines are on the cabinet’s bottom right side. Connect
these drain lines to a safe location.
Programmable Logic Controller
An integrated PLC within the cabinet that features smart
timing to maximize the generator’s performance. It controls
the valve timing and sequencing to move compressed gas
throughout the system. It also has a smart feature to automati-
cally switch between different “modes” based on the current
run stages (see Chapter 7: System Operation for more about
the unit’s functionality).
Safety Relief Valves
The installed ASME safety relief valves add additional safe-
ty to protect component failures.
Nitrogen Tank
A nitrogen tank inside the cabinet comes with ball valves,
safety relief, and a gauge.
Automatic Cut-In and Cut-Out
The generator starts and stops based on a pressure switch.
Do not adjust the factory preset cut-in and out pressure without
first consulting with South-Tek Systems.
Patented BlastOff ® – Leak Detection System
The “BlastOff
®
Leak Detection” is a patented feature which
sends an alarm if it detects a possible gas leak. The alarm sig-
nal can be an audible, visual, and dry contact connection to the
“Building Management System (BMS)”. Power cycle the unit to
reset the alarm but avoid doing this without finding the cause,
as it will shorten the generator’s life.

Operation
The nitrogen generator uses valve sequencing to produce
nitrogen. The design meets specifications of a fire protection
system. Consult with South-Tek System for written approval
before performing any field changes or customization. Unau -
thorized changes void all warranties and may cause damages
or malfunctions to the system.
This section describes the major control functions and in-
strumentations associated with the nitrogen generators. All
programs are proprietary and password protected from the
factory. Do not alter any controls or instrumentations. Changes
without South-Tek Systems’ written consent voids the perfor-
mance specifications.
Controller Modes
To utilize the buttons on the front of the controller the unit
must be in “S” or “Switch” mode and unlocked. If the system
is displaying “LOCK”, the Mode Select Button may be pressed
and held to unlock the controller (repeat this step if a system
lockout is desired). To change to Switch Mode, press the Mode
Select Button when the controller is unlocked until the System
Mode Indicator displays “S”. This mode allows access to two
features:
• Alarm Simulation (5) – Hold the Alarm Simulation Button
for 3 seconds or press the filter replacement reset button
3 times within 3 seconds to activate. This will simulate an
alarm condition and trip the alarm dry contact in the unit
for 2 seconds so that proper functioning can be confirmed.
• Filter Change Reset (0) – When a new FRP (Filter Re-
placement Kit) is installed, the 1000- hour filter change
time must be reset. After replacing the filter elements,
press and hold the Filter Change Reset Button for 7 sec-
onds. An audible beep will confirm that the time is reset
and filter alarm will be reset. (
Note:
this will also trigger the
Customer Alarm Relay for one second)
