GENERAL INFORMATION
The Amerex industrial Dry Chemical Fire Suppression System is designed and has been tested
to provide fire protection for industrial operations categorized as Local Application (Overhead),
Tankside, Total Flooding, Vehicle Paint Spray Booth, and Open Front Paint Spray Booth hazards.
It is manufactured by the Amerex Corporation of Trussville, Alabama.
Amerex Industrial Systems are a pre-engineered type as defined in NFPA 17- Standard for Dry
Chemical Extinguishing Systems. The NFPA 17 definition states pre-engineered systems as
"having predetermined flow rates, nozzle pressures, and quantifies of dry chemical." It also
states that "limitations on hazards that are pemritted to be protected by these systems and piping
and nozzle configurations are contained in the manufacturers listed installation and maintenance
manual, which is part of the listing of the system."
It is essential that all installations, maintenance, and inspections of the Amerex Industrial System
be performed in compliance with this manual and NFPA 17. Those Individuals responsible for
the design, installation, setting into service, maintenance and recharging of the Amerex
industrial Dry Chemical System must be trained by Amerex and hold a current Amerex
Certificate. All piping limitations, nozzle coverages, detector placements, etc. have been proven
and established through exhaustive testing by Underwriters Laboratories, Inc.. Use of
components other than those referenced in this manual, or installations outside the limitations
stated in this manual is unacceptable.
I.I.L. Listing
The Amerex Industrial System is an Underwriters Laboratories and ULC Listed pre-engineered
extinguishing unit. The system has been evaluated in accordance with U.L. Standard 1254_
Tests required for listing under this standard involve fire tests under specific conditions involving a
variety of Local Application, Total Flooding, or Screening. Each test fire was allowed to reach its
maximum intensity before agent was discharged. Each test was repeated using both maximum
and minimum piping, with variations in agent storage pressure to simulate maximum and
minimum temperature ratings. Each test fire was extinguished without splashing of the liquid fuel.
Design
The system is composed of an agent cylinder! discharge valve charged with Amerex ABC Dry
Chemical and either a Mechanical Release Module (MRM) a Pneumatic Release Module (PRM)
or an Electrical Release Module (ERM). The quantity of detectors, fusible links, nozzles, comer
pulleys, pulley tees and manual pull stations will vary depending on design.
The system operates either automatically if actuated by a detector or manually if actuated by a
manual pull station. Upon system operation, energy sources for the appliances are shut off
immediately. The MRM, PRM and ERM incorporate mechanical and electrical provisions to
facilitate the operation of auxilliary devices such as mechanical or electric gas valves and remote
audible or visual signal devices.

COMPONENT DESCRIPTIONS
Agent Cylinder Assembly (item 1): The agent cylinder is available in three configurations. Models
IS18ABC (PIN 16206), IS35ABC (PIN 16207) , and IS45ABC (PIN 16208) are charged with AMEREX multi-
purpose ABC dry chemical agent The cylinder assemblies are stored pressure designs with an operating
pressure of 350 psi (2413 KPa) at 70OF (210C). The cylinders are constructed of welded steel to DOT 4BW
350 specifications. Al three models are 9 inches (22.9 cm) in diameter. The discharge valve, which is
common to all agent cylinders, is of rugged forged brass construction. The valve is equipped with a 350 psi
(2413 KPa) pressure gauge and a fusible element pressure relief plug. The valve controls agent discharge
via a spring loaded, internal sealing stem that must be depressed from the top of the valve to initiate agent
discharge. The operating temperature of this and other listed system components is -40OF to 120OF (-40°C to
49°C) for Total Flood, 20OF to 120OF (-29°C to 49°C) for Tankside Local Application, Vehicle and Open Front
Paint Spray Booths, and 32°F to 120°F (0°C to 49°C) for Overhead Local Application. Warning: Agent
cylinders are shipped from the AMEREX factory fully charged with a shipping plate installed on the top of the
valve to prevent accidental agent discharge and an anti -recoil plate on the valve outlet to redirect chemical
flow should an accidental discharge occur. Both of these plates must be removed at installation.

Agent Cylinder Bracket (item 3): The agent cylinder bracket is
constructed from 1/8 inch (3.2mm) steel & painted to resist corrosion. The
part number for this cylinder bracket is P/N 14929. This bracket assembly
will accommodate either the IS18 or the taller IS35145 agent cylinders, and
contains two stainless steel straps for securing the cylinder to the bracket
back (use only one strap for the IS18 cylinder).

Mechanical Release Module (item 5): Referred to as the
MRM, PIN 11977 is used to actuate the Agent Cylinder
Discharge Valve either automatically or manually by puncturing
a Nitrogen Cylinder. The pressure from the cylinder
pneumatically actuates the Pneumatic Control Head(s), which,
in turn, opens the Agent Cylinder Valve(s).
Automatic release of dry chemical agent is accomplished when
a Fusible Link Detector separates under a fire condition and
releases tension on the cable. This causes a spring -loaded
plunger to perforate the seal on the Nitrogen Cylinder and
releases nitrogen through the Actuation Hose/Piping Network to
the Pneumatic Control Head(s) / Discharge Valve(s).
Manual release of agent is accomplished by pulling on a
Manual Pull Station, which is connected to the Mechanical
Release Module by a cable.
The Mechanical Release Module is intended for indoor use
only, and is equipped with two Microswitch (PIN 12524) for
electrical signaling, power shutdown and other auxiliary
functions. An additional two Microswitches may be added.

iw MRM II combines the same features and functionality of
the 11977 MRM (see above) along with increased
detection capabilities and a far simpler means of setting
the detection cable tension. The MRM II is available in the
following configurations, now pre -installed in its own
enclosure:
PIN 18000: MRM II with red -painted steel enclosure
PIN 18001: MRM 11 with stainless steel enclosure
The method of setting the detection cable tension on the
MRM II does not require the use of any tools (once the
cable is locked down into the large, knurled wind-up
spool). A large lever to the right of the spool is used to
increase the cable tension. Alignment of the bottom edge
of the lever with markings on a label on the mounting plate
indicates when the proper tension has been reached. In
addition to being easier to set up, lowering cable tension to
change out detection links is now also much simpler.

Detector — MRM Installations
(Item 211, PIN 12508:
Each Detector in the Amerex Industrial System is comprised of three parts. The Detector Bracket, Detector
Linkage, and the Fusible Link or Job Link (ordered separately). The Bracket serves as support for the
Linkage and is attached to a rigid surface. The Linkage supports the Link and a continuous Cable under
tension. At a predetermined temperature, the Link will separate, relieving tension on the Cable and actuating
the system.
This manual will refer to Series and Terminal Detectors. There is no difference in part numbers or
dimensions between Series and Terminal Detectors. A Terminal Detector is the last or only detector in the
network and the Cable must be "terminated" there. A Series Detector is any detector located between the
Terminal Detector and the Mechanical Release Module in the Detection Network.
Fusible Links (Item 22) — MRM Installations
Four temperature ratings of the Fusible Links are used. They are of the electric solder type link which will
melt at a predetermined temperature allowing the two halves of the link to separate.

Mechanical Time Delay — MRM installations: (item 18): This device
(PIN 15765) is used with MRM-equipped systems when a Discharge Time
Delay of 15 seconds is required (Refer to UL 1254 Standard for details). It is
the first component to connect into the MRM, and is packaged with its own
mounting clamp. In the event of system actuation, the Mechanical or Electrical
Gas Valves trip immediately, along with any electrical component connected
the Microswitch(es), but the high pressure nitrogen actuation gas will be
delayed before entering the Actuation Network. The reason for this is to allow
for exhaust fan run-down in certain paint spray booth applications. It is not
needed for ERM installations, since the ERM can electronically control the time
delay function, if required.
Vent Check (Item 19): The Vent Check, PIN 10173, is a safety I N*jC7-V
PT
device that installs in the Pneumatic Control Head. Its function is to
bleed any slowly accumulating pressure that could cause the
Pneumatic Control Head to open the agent cylinder valve prematurely.
Examples of possible pressure sources include a slow leak in the
rupture disc of an N2 cylinder, or normal temperature4nduced
expansion of the air and moisture trapped in the actuation network. A
vent check must be used on all pneumatically actuated systems. Use
of a pipe plug or other type of "stopper" is unacceptable and can lead
to system malfunctions. The body of the vent check is constructed of 16
machined brass. The inside of the vent check contains a spring and
nylon ball. Slowly accumulating gas can pass around the nylon ball and bleed to the atmosphere. However,
the rapid accumulation of actuation pressure from the N2 cylinder causes the ball to compress the spring and
seal on a tapered seat, blocking the bleed hole. Following an actuation, the vent check can be used to
exhaust residual actuation pressure by unseating the nylon ball (typically, with a small piece of wire or the tip
of a ball point pen). In installations using multiple agent cylinders, the vent check is installed only in one
Pneumatic Control Head at the end of the actuation network.
Actuation Tubing (item 20): The function of the actuation line is to carry high pressure nitrogen gas from
the N2 cylinder to the pneumatic control head. Actuation components are installer supplied.

Detector — MRM Installations
(Item 211, PIN 12508:
Each Detector in the Amerex Industrial System is comprised of three parts. The Detector Bracket, Detector
Linkage, and the Fusible Link or Job Link (ordered separately). The Bracket serves as support for the
Linkage and is attached to a rigid surface. The Linkage supports the Link and a continuous Cable under
tension. At a predetermined temperature, the Link will separate, relieving tension on the Cable and actuating
the system.
This manual will refer to Series and Terminal Detectors. There is no difference in part numbers or
dimensions between Series and Terminal Detectors. A Terminal Detector is the last or only detector in the
network and the Cable must be "terminated" there. A Series Detector is any detector located between the
Terminal Detector and the Mechanical Release Module in the Detection Network.
Fusible Links (Item 22) — MRM Installations
Four temperature ratings of the Fusible Links are used. They are of the electric solder type link which will
melt at a predetermined temperature allowing the two halves of the link to separate.

Piping Reauirements:
Piping diagrams include limitations on pipe length and fittings. System piping must be balanced. Balanced
piping is that in which the difference between the shortest actual pipe length from the 1" TEE to nozzle and
the longest actual pipe length from the I" TEE to nozzle does not exceed 10% of the longest actual pipe
length from TEE to nozzle. The number and type of fittings for both TEE to nozzle sections must be equal.
All piping must be Schedule 40, hot -dipped galvanized steel pipe, and all fittings must be 1501b. class.
Examples of acceptable fitting materials include hot -dipped galvanized malleable iron, ductile iron, or steel.
Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used
for changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive
atmospheres.
Nozzle Placement and Orientation:
The TFP Nozzle has been developed to provide application of extinguishing agent from the upper
perimeter of the module being protected. The nozzle is to be installed through the top of the module, at the
closest point to the intersection of the module wall and module top. The nozzle location, laterally, is to be
at the midpoint (+/-10%) of the adjacent module edge. The tip of the nozzle must be within 6" of its entry
point. The nozzle is to be installed vertically, with the orifices pointing downward, and the engraved arrow
pointing into the protected module. The arrow must be aligned perpendicular to the adjacent wall, when
viewed directly from below. Proper nozzle placement is shown as follows:
