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 quantities of dry chemical." It also
states that "limitations on hazards that are permitted to be protected by these systems and piping
and nozzle configurations are contained in the manufacturer's 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 Underwriter's Laboratories, Inc.. Use of
components other than those referenced in this manual, or installations outside the limitations
stated in this manual is unacceptable.
U.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)
an Electrical Release Module (ERM), or an Electric Control Head (ECH). The quantity of
detectors, fusible links, nozzles, corner 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.
Temperature Limitations:
Local Application, Overhead: 32 ° F to 120 ° F (0 ° C to 49 ° C)
Local Application, Tankside: -20 ° F to 120 ° F ( -29 ° C to 49 ° C)
Total Flood: -40 ° F to 120 ° F (-40 ° C to 49 ° C)
Vehicle Paint Spray Booths: -20 ° F to 120 ° F ( -29 ° C to 49 ° C)
Open Front Paint Spray Booths: -20 ° F to 120 ° F ( -29 ° C to 49 ° C)

COMPONENT DESCRIPTIONS
Agent Cylinder Assembly (Item 1): The agent cylinder is available in three configurations. Models
ISI8ABC (P /N 16206), IS35ABC (P /N 16207) , and IS45ABC (P /N 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 70 ° F (21 ° C). The cylinders are constructed of welded steel to DOT 4BW
350 specifications. All 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 -40 ° F to 120 ° F ( -40 ° C to
49 ° C) for Total Flood, -20 ° F to 120 ° F ( -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.

Al �C ,, i opens the Agent Cylinder Valve(s).
o �
#i
�( ' `U Automatic release of dry chemical agent is accomplished when
C� l �i j ` a Fusible Link Detector separates under a fire condition and
releases tension on the cable. This causes a spring - loaded
0,, � Uplunger to perforate the seal on the Nitrogen Cylinder and
releases nitrogen through the Actuation Hose /Piping Network to
14
\ �� the Pneumatic Control Head(s) / Discharge Valve(s).
6 4 /� Manual release of agent is accomplished by pulling on a Manual
�I % 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 one Microswitch (P /N 12524) for electrical
o signaling, power shutdown and other auxiliary functions. An
additional three Microswitches may be added.
•
,---J Mechanical Release Module II (Item 5): The new
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
'6 °O � following configurations, now pre - installed in its own
J enclosure:
i����
t o P/ 18000: MRM II with red - painted steel enclosure
I— P/N 18001: MRM II with stainless steel enclosure
The method of setting the detection cable tension on the
I M RM II does not require the use of any tools (once the
l 4 ' , , cable is locked down into the large, knurled wind -up spool).
J A large lever to the right of the spool is used to increase
O 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.

the responsibility of the Certified Installer to ensure that e proper system components are being utilized, and that
the system meets the limitations and parameters listed i this chapter. Those individuals responsible for the
design of the Amerex Industrial Dry Chemical Syste must be trained by Amerex and hold a current
Amerex Certificate. Amerex will not be responsible for system design, installation, or maintenance performed by
any non - certified person(s).
ABC Dry Chemical
It is necessary for the system designer to consider the combustible material found in the hazard area to ensure
proper protection. The agent used in the Amerex Industrial System is suitable for Class A, B, and C hazards. The
following are the hazard class definitions:
"A" Class - Ordinary solid carbonaceous combustibles. These include wood, paper, cloth, fiberglass, and plastics.
"B" Class - Flammable liquids and gases. These includ paints, solvents, gasoline, oils, and hydraulic fluids.
"C" Class - Electrical appliances. These include compu ers, power generators, and power transformers.
ABC (monoammonium phosphate- based) is suitable for se with all "A", "B", and "C" Class hazards. Dry Chemical
Type extinguishing systems are inappropriate for the pro ection of Class D hazards. As per NFPA 17, pre -
engineered dry chemical systems are not approved for ep- seated or burrowing fires (such as ordinary
combustibles, where the agent cannot reach the point of combustion), or on chemicals that contain their own
oxygen supply (such as cellulose nitrate). Do not mix different types of agents, or agents from different
manufacturers. Chemical reactions may occur when inc9mpatible chemicals are mixed. Keep in mind that the �,
agent used for each system must be acceptable to the A iithority Having Jurisdiction (AHJ).
Choosing the Proper Type of System
It is necessary for the system designer to consider the physical characteristics and layout of the hazard area to
ensure proper protection. The system must meet the criteria for a particular hazard and the requirements of NFPA
17 for the system to be effective. Underwriters Laboratories, under the UL 1254 test protocol, has evaluated the
Amerex Industrial Dry Chemical System in each of five separate hazard categories. Each category has its own
specific installation requirements. It is imperative that th system designer properly identify the fire hazard in order
to effectively remain within the UL listing parameters. Th remainder of Section 3A is dedicated to matching the
Amerex system to each of the five separate hazard coverFage categories:
3A.1) Local Application - Overhead - This system is used for applying agent to an area from above the area.
Typical applications include dip tanks, power generators, and transformers. The maximum nozzle height for
overhead protection is 10 feet.
3A.2) Local Application - Tankside - This system is used for applying agent across a hazard area from the
side of the area. Typical applications include, but are not limited to, dip tanks, quench tanks, and solvent tanks
where overhead obstructions are present.
3A.3) Total Flooding - This system is used to fill a volume with agent to protect any hazard within that volume.
Typical applications include hazardous storage containers and warehouses where sprinkler protection is
unavailable. Total flooding systems require a fixed enclosure to be present around the hazard area to allow the
system to build up the proper concentration of agent within the hazard area. Whether an enclosure is suitable for
allowing total flooding protection depends on the unclosable opening percentage of the enclosure. Unclosable
opening percentage is calculated as the area of the opening divided by the total area of the sides, top and bottom of
the enclosure. Total flooding protection is qualified for use on hazards whose enclosure has up to 5%
UL EX 5208
November 15, 2007
•
Part Number 15040 System Design Page 3A -2
unclosable opening. For enclosures that have greater than 5% unclosable opening, total flooding protection is not
qualified. Use Local Application Overhead for these hazards.
3A.4) Vehicle Paint Spray Booths — This system is selected to protect an enclosed structure that is designed
for the purpose of painting vehicles. This structure generally comprises of a work area, separated from a plenum by
a filter bank, and an exhaust duct. There are numerous configurations of a vehicle paint spray booth, and all areas
(work area, plenum, and exhaust duct) must be simultaneously protected with the coverage from the Amerex
system.
3A.5) Open Front Paint Spray Booths — This system is used to protect a paint spray booth with an open
front. The booth structure still comprises of a work area, separated from a plenum by a filter bank, and an exhaust
duct. The opening at the front of the booth requires special screening of dry chemical to be effective.

3A.4 Vehicle Paint Spray Booths (VPSB):
The Amerex Vehicle Paint Spray Booth Fire Suppression System is of the pre - engineered type as defined by the
NFPA Standard for Dry Chemical Extinguishing Systems, NFPA 17 and the Standard for Spray Application Using
Flammable or Combustible Materials, NFPA 33. The extinguishing systems described in this manual are intended
to be installed, maintained, and serviced in accordance with NFPA 17 and NFPA 33. The Amerex Vehicle Paint
Spray Booth System has been evaluated by Underwriters Laboratories (UL) in accordance with the specific test
protocol found in the UL1254 Standard (Pre - engineered Dry Chemical System Units).
Used for painting or coating cars, trucks, buses and large mobile equipment, Vehicle Paint Spray Booths come in
a variety of configurations and sizes. The basic volumes of a Vehicle Paint Spray Booth to be protected by the
Amerex System consists of three main components. They are:
Work Area - Where the vehicle is painted.
Plenum(s) - Exhaust chambers adjacent to the Work Area. Plenums utilize filters to trap overspray particles
that escape from the Work Area. The primary purpose of the plenum is to expose a sufficiently large area of
filter media to the overspray that is carried along in a smooth current of air.
Duct(s) - Fan - powered air channels that draw air through the Work Area, the Plenum(s), and finally out
through the Duct.
CAUTION:
NFPA 33 Standard for Spray Application Using Flammable and Combustible Materials classifies the interior
sections of paint spray booths, and certain areas adjacent to booth openings, as Class -I or Class -I1,
Division -1 or Division -2 locations. Electrical components of an Industrial Dry Chemical System, such as
thermostats located within these areas shall be rated for use in classified areas, and all wiring to these
components shall conform to the provisions of NFPA 70, National Electrical Code, for Class —I or Class -II,
Division -1 or Division -2 locations. Any Industrial System Control Head with a Microswitch is not suitable
'` for use in a classified area.
Most of the time, the air is drawn downward over the vehicle during the painting process (as in either an Under
Floor, Pit, or Down Draft (Side - Exhaust) configuration). Other booths, such as a Back Draft or Pant -Leg
(Horseshoe) design, draw air down and across, toward the rear of the booth. Fresh air is usually drawn in through
intake filters either in the Work Area ceiling or on the upper walls of the Work Area. Many installations utilize a
Heated Make -Up / Recirculation option, which re- circulates filtered, heated air through the booth, thereby being
more energy efficient.
The Amerex Vehicle Paint Spray Booth System requires that the booth exhaust fan(s) be shut down prior to the
discharge of the ABC dry chemical. This is accomplished with the use of the Mechanical Time Delay (p /n 15765)
with mechanically - released systems, or by the use of the Amerex Electric Control Panel (p /n 15780) with the use of
the timed discharge circuit. It is the responsibility of the installer to properly identify the configuration of the booth
and to follow the requirements of this manual in order to achieve proper fire suppression. Sometimes, additional
turns, baffles, or obstructions in the booth's plenum and duct may dictate the use of additional nozzles in order to
ensure good distribution of dry chemical.

3A.4 Vehicle Paint Spray Booths (continued):
Piping Requirements: 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 any %" TEE
to nozzle and the longest actual pipe length from any 3 /." TEE to nozzle does not exceed 10% of the longest actual
pipe length from any 3 /4 ' TEE to nozzle. Piping runs from the 1" TEE to each of the' /." TEE's must be equal in
length. The number and type of fittings for all TEE to nozzle sections must be equal.
All piping must be Schedule 40, hot - dipped galvanized steel pipe, and all fittings must be 150 lb. class, minimum.
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.
3A.4.1 Work Area Coverage, VPSB
There are two distinctly different nozzle and piping arrangements for protecting the Work Area using the IS45ABC
cylinder. The first arrangement is "Standard Work Area Coverage ", and the second is "Module Perimeter
Work Area Coverage" outlined as follows:
3A.4.1.1 Standard Work Area Coverage, VPSB
The Amerex Vehicle Paint Spray Booth System is flexible enough to protect a wide variety of Vehicle Booths of
various dimensions. The maximum booth height is 23'4 ". As noted, the IS45 cylinder is used with two or four
nozzles, and each of the nozzles has been tested to protect a Work Area Module. A Work Area can be thought of
as a series of `boxes', or Modules, stacked together, each protected with a nozzle. The maximum parameters for
each Module are given as follows:
Module Volume: 1,050 ft. per nozzle, two or four TF nozzles per IS45ABC
Maximum Module Area: 105 ft. per nozzle for booths up to 10 ft. in height;*
45 ft. for booths at 23 ft., 4 in. height.*
Maximum Module Height: 23 ft., 4 in.
Maximum Module Side Length:
Module Center: 14 ft. for booths up to 10 ft. tall`
9 ft for booths at 23'4" tall*
Booth Edge: 14 ft for booths up to 10 ft tall
Centerline: 15 ft. (widthwise); booth height limited to 10' tall with this option
*Note: For Module Center Installations with booth heights between 10' and 23'4 ", reference table 3A -1
Maximum Nozzle Offset — Module Center Entry: Within a 2.5 ft. radius semicircle from center of module, no
less than 12" from any side of the module (booth); the curved portion of the semicircle must curve
away from the centerline of the booth; the tip of the nozzle within 6" of ceiling.
Maximum Nozzle Offset — Booth Edge Entry: Entry into the module at the closest point to the intersection of
the booth wall and ceiling. The nozzle location, horizontally, is at the midpoint of the longest side of the
module, +1- 2 feet. The tip of the nozzle must be within 6" of its entry point. This option is allowable
only for booths 10 feet or less in height.
Maximum Nozzle Offset — Booth Centerline Entry: This option is available where nozzle entry is only
possible along the centerline of the booth ceiling. Maximum booth height for this option is 10 feet.
This installation configuration allows for a maximum module side length of 15', which is the width of the
Work Area, in this case. There is no allowable nozzle offset for this option. The first and fourth nozzles
are to be located at 12" from the front and back of the booth, respectively. The second and third
UL EX 5208
November 15, 2007
Part Number 15040 System Design Page 3A -18
nozzles are to be spaced equally between the first and fourth nozzles. The tip of the nozzle must be
within 6" of the ceiling.
3A.4.1.1 Standard Work Area Coverage, VPSB (continued)
In order to insure that the longest side length is not exceeded for each nozzle module, Table 3A -1 must be used to
obtain the side length of the module, when one side is known. For example, a work area that is 16 feet in height
and 20 feet in width will need four nozzles across the width of the booth. Therefore, 20 divided by 4 = 5 feet.
Looking at the 16 feet (height) column, and following it down until the 5 foot length is located, the remaining side
length is: 11.75 feet.

Piping Requirements:
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 1" 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.
UL EX 5208
November 15, 2007
Part Number 15040 System Design Page 3A -27
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 ( +1- 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:

Part Number 15040 System Design Page 3A -45
The Amerex Open Front Paint Spray Booth Fire Suppression System is of the pre - engineered type as defined by
the NFPA Standard for Dry Chemical Extinguishing Systems, NFPA 17 and the Standard for Spray Application
Using Flammable or Combustible Materials, NFPA 33. The extinguishing systems described in this manual are
intended to be installed, maintained, and serviced in accordance with NFPA 17 and NFPA 33. The Amerex Open
Front Paint Spray Booth System has been evaluated by Underwriters Laboratories (UL) in accordance with the
specific test protocol found in the UL1254 Standard (Pre- engineered Dry Chemical System Units). Although NFPA
33 (Chapter 9) permits Dry Chemical Systems to protect dry powder and electrostatic liquid spray booths
under certain criteria, Amerex prohibits installation of the IS system in such booths.
Open Front Paint Spray Booths come in a variety of dimensions, but only one basic configuration. The basic
volumes of an Open Front Paint Spray Booth to be protected by the Amerex System consists of three main
components. They are:
Work Area - Where the part or equipment is painted with possibly flammable or combustible material (i.e.
paints, finishes, lacquers, etc.). The Work Area is open on the front, but enclosed on the sides and top, with a
filter bank at the back.
Plenum - Exhaust chamber at the rear of the Work Area. Plenums utilize filters to trap overspray particles
that escape from the Work Area. Air is drawn in through the front of the booth, across the Work Area, and back
through the Plenum.
Duct - Fan - powered air channel that draws air through the Work Area, the Plenum, and finally out through the
Duct.
It is not necessary to shut the exhaust fan down upon system discharge; however, check with the authority
having jurisdiction. It is the responsibility of the installer to properly identify the configuration of the booth and to
follow the requirements of this manual in order to achieve proper fire suppression.
CAUTION:
NFPA 33 Standard for Spray Application Using Flammable and Combustible Materials classifies the interior
sections of paint spray booths, and certain areas adjacent to booth openings, as Class -I or Class -Ii,
Division -2 Locations. Electrical components of an Industrial Dry Chemical System, such as thermostats
located within these areas shall be rated for use in classified areas, and all wiring to these components
shall conform to the provisions of NFPA 70, National Electrical Code, for Class —I or Class -II, Division -2
Locations. Any Industrial System Control Head with a Microswitch is not suitable for use in a classified
area.

SCR 16192 Screening the opening of the Work Area
D/P 16190 Exhaust Duct
Cylinders:
The Model ISI8ABC and IS35ABC are used for Open Front Paint Spray Booth applications in various
configurations.
Temperature Range:
The operating temperature range for Open Front Paint Spray Booth applications is
-20 ° F to 120 ° F ( -29 ° C to 49 ° C).
Piping Requirements:
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 any 3 /4" TEE to
nozzle and the longest actual pipe length from any 3 /4' TEE to nozzle does not exceed 10% of the longest actual
pipe length from any g/." TEE to nozzle. Piping runs from the 1" TEE to each of the 3 /4" TEE's must be equal in
length. The number and type of fittings for all TEE to nozzle sections must be equal.

All piping must be Schedule 40, hot - dipped galvanized steel pipe, and all fittings must be 150 lb. class,
minimum. 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.

Below are the maximum dimensions of an Open Front booth utilizing two IS35ABC cylinders and an IS18ABC. The
two IS35ABC's each support an SCR Nozzle, two Work Area Nozzles (TF), and a Plenum Nozzle (TF). The single
IS18ABC is used for either one or two Duct Nozzles (D /P); one D/P is shown.
This example illustrates that by utilizing multiple IS35ABC cylinders, the coverage of the booth can be expanded in 8
foot width increments. Examples: a 24' wide by 16' deep Work Area (with 4' deep Plenum) is covered with three
IS35ABC cylinders. Likewise, a 32' wide by 16' deep Work Area (with 4' deep Plenum) is covered with four
IS35ABC cylinders. Duct protection would be covered with separate cylinders, in both cases.

CHAPTER 3, SYSTEM DESIGN
Section B: Hardware Selection and Limitations
Those individuals responsible for the design of the Amerex Industrial Dry Chemical System must be trained
by Amerex and hold a current Amerex Certificate.
1. Detection Network, MRM Installations:
Optimum Fire Suppression System performance depends on proper Detection Network design. This section
discusses the type of Detectors used, their selection, placement and design limitations.
The Amerex Industrial Fire Suppression System uses a continuous cable, Corner Pulleys, D ector Bracket,
Detector Linkage, Fusible Links, Conduit Offset, and a Terminal Link Connector for the Dete ion Network.
The quantity of detectors to be used in an MRM system will depend on the ceiling area and h ight. Fusible Links of
the metal -alloy type (p /n's 12326,12327, 12328, and 12329) can be spaced every 10 feet for mooth ceilings up to
12 feet high. The Job Quick Response Links (p /n 16225, 16226, and 16227) can be spaced very 20 feet for
smooth ceilings up to 12 feet high. A detector is required at the interface of the duct and ple m, as well as
downstream of any obstruction (such as a damper) or ignition source (such as a fan). Consu NFPA 72 for
reductions in spacing for ceiling heights in excess of 12 feet, and for spacing guidelines whe different
arrangements are encountered.
Note: Standard Response Fusible Links are NOT recommended for use in Paint Spray Booths because of their
slow reaction time. For this reason, Amerex recommends either the Job Quick Response Links, or the Electric
Thermal Detectors (see section on ERM Detection Networks). However, Standard Response Fusible Links may be
used if permitted by the authority having jurisdiction.
----'` Fusible Link Detectors are required in all hazard areas protected by the Amerex Industrial Fir Suppression
Systems for automatic system operation. The adaptation of Fusible Links to the Mechanicaltelease Module is
described in Chapter 4. A temperature survey must be performed to determine the maximum ambient temperature
of the hazard survey. The selection of the Fusible Links should be made according to the temperature measured:

2. Detection Network, ERM 1 ECH Installations:
The Electrical Release Module (ERM) and Electrical Control Head (ECH) systems use four -wire, rate of rise
Thermal Detectors as the system initiating device. The advantages over fusible link systems are that the reponse
time is faster, and the device is resettable. Refer to Design and Installation Manual, p/n 15827, for more
information on the ERM.
CAUTION:
It is likely that industrial applications involving FLAMMABLE or COMBUSTIBLE liquids will be
enclosed within or surrounded by areas that will be classified as CLASS I or CLASS II, DIVISION
1 or DIVISION 2 locations. Dry chemical system electrical components, such as thermostats,
located within these areas shall be rated for use in classified areas, and all wiring to these
components shall conform to the provisions of NFPA 70, National Electrical Code, for CLASS I or
CLASS II, DIVISION 1 or 2 locations. Any industrial system Control Head with a microswitch is
not suitable for use in a classified area.
In order to minimize delays in thermostat response, it is imperative that a temperature survey be performed at all
locations where thermostats will be installed. The survey must be conducted under maximum operating conditions
to determine the peak temperatures that are expected to be reached. Readings should taken with and without
airflow. Once this information is established, select a detector with a setpoint between approximately 75 and 100 ° F
HIGHER than the maximum expected temperature for that particular mounting location. The probe of the detector
should be mounted so that it will be exposed to escaping hot gases, in the event of a fire. The following are the
Thermal Detectors utilized with an ERM / ECH installation:
Temperature Rating Part Number

190 88 16194
194 90 16236
225 107 16195
325 163 16196
The quantity of detectors to be used in a system will depend on the ceiling area and height. The maximum number
of detectors that can be used for a given system is 400. Detectors can be spaced every 20 feet for smooth ceilings
up to 12 feet high. A detector is required at the interface of the duct and plenum, as well as downstream of any
obstruction (such as a damper) or ignition source (such as a fan). Consult NFPA 72 for reductions in spacing for
ceiling heights in excess of 12 feet, and for spacing guidelines when different arrangements are encountered.

5. d) Remote Nitrogen Actuation (RNA) Network Limitations:
The Remote Nitrogen Actuator, p/n 16197, is a device used in conjunction with either the MRM, PRM, ERM or ECH
when the number of Agent Cylinders required exceeds the maximum number supported by the releasing module.
When an RNA is used, the high pressure gas from the releasing module is used to fire the RNA, which, in turn,
fires the Pneumatic Actuators attached to the Agent Cylinders. A total of 200 feet of copper tubing is allowed when
tee'd from the outlet of the RNA; the longest distance allowed from the RNA to the last Pneumatic Control Head is
100 feet. Each 100 foot long section of tubing can support ten (10) Pneumatic Control Heads. Therefore, each
RNA can support 20 Agent Cylinders. See the following illustration for RNA limitations.
Note:
A Vent Check (P /N 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder of one of
the tubing branches from the RNA. The last Pneumatic Control Head on the opposite branch must be plugged with
a high pressure %." NPT pipe plug. Also, a Vent Check is required at the pressure inlet of the RNA (where the
copper tubing from the control panel enters the RNA). If there are more than one RNA's installed, only one vent
check is required on the control panel -to -RNA network. Use a high pressure %" male branch tee at the RNA to
install the Vent Check. The Vent Check is designed to release any slowly built up pressure from the actuation lines.
This device should be accessible for pressure bleed -off after system discharge.

,... 5. e) Remote Nitrogen Actuation (RNA) Network Limitations With MRM Installations:
If a system installation requires more than six Agent Cylinders with an MRM, it is possible to use either one or two
Remote Nitrogen Actuators in the Actuation Network. Each Remote Nitrogen Actuator (P /N 16197) is capable of
firing up to twenty (20) Agent Cylinders; two Remote Nitrogen Actuators could therefore fire a maximum of forty (40)
Agent Cylinders when used with one MRM. All Agent Cylinders are fired by the Remote Nitrogen Actuator(s), when
used, and the nitrogen cylinder in the control panel is dedicated only to firing the Remote Actuator(s).
Note:
A Vent Check (P /N 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder of one of
the tubing branches from the RNA. The last Pneumatic Control Head on the opposite branch must be plugged with
a high pressure %" NPT pipe plug. Also, a Vent Check is required at the pressure inlet of the RNA (where the
copper tubing from the control panel enters the RNA). If there are more than one RNA's installed, only one vent

5. f) Remote Nitrogen Actuation (RNA) Network Limitations with ERM / ECH Installations:
If an ERM system installation requires more than ten Agent Cylinders (or more than 20 Agent Cylinders with an ECH
installation) one two, three or four Remote Nitrogen Actuators (RNA's) may be used with the following tubing
limitations. Each Remote Nitrogen Actuator (P /N 16197) is capable of firing up to twenty (20) Agent Cylinders; four
Remote Nitrogen Actuators could therefore fire a maximum of eighty (80) Agent Cylinders when used with the ERM
(ECH). All Agent Cylinders shall be fired by the Remote Nitrogen Actuator(s), when used, and the nitrogen cylinder
in either the ERM or ECH is dedicated only to firing the Remote Nitrogen Actuators.
Note:
A Vent Check (P /N 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder of one of
the tubing branches from the RNA. The last Pneumatic Control Head on the opposite branch must be plugged with
a high pressure 1 /4" NPT pipe plug. Also, a Vent Check is required at the pressure inlet of the RNA (where the
copper tubing from the releasing module enters the RNA). If there are more than one RNA's installed, only one vent
check is required on the releasing module -to -RNA network. Use a high pressure' /." male branch tee at the RNA to
install the Vent Check. The Vent Check is designed to release any slowly built up pressure from the actuation lines.
This device should be accessible for pressure bleed -off after system discharge.

6. Mechanical Gas Valve Applications (MRM or ERM):
u
Both the MRM and the ERM close the Mechanical Gas Valve immediately upon system discharge. A pneumatic
and mechanical action in the Module pulls on a cable attached to the mechanical gas valve, unlatching the valve
and allowing an internal spring within the valve body to provide the closing force. Connection of the cable from the
valve to the MRM under tension maintains gas valve in an open position.
Mechanical Gas Valve:
A Mechanical Gas Valve Trip Cylinder assembly must be used with any mechanical gas valve. The gas valve trip
cylinder assembly (P /N 12740) is included with all Amerex manufactured gas valves, but may be ordered separately
for use with gas valves listed in this manual supplied by other manufacturers.
tip

AMEREX PART NO 12740
See Chapter 1 "System Components" for all mechanical gas valves that are suitable for use with the Amerex
Industrial Dry Chemical System. The use of any other mechanical gas valves will void the U.L. Listing for the
system installation. All of the listed valves have female NPT threads. The location of the gas valve should be
accessible and approved by the Local Authority Having Jurisdiction. Installation should be performed by a
contractor licensed and qualified for such work.
Mechanical Gas Valve Actuation Network Limitations:
The Mechanical Gas Valve Actuation Network consists of Cable, Corner Pulleys, Pulley Tee, Gas Valve and

7. Electrical Gas Valve Operation:
110 VAC Electrical Gas Valves may be used in place of the Mechanical Gas Valves. The Electrical Shut -Off Valve
used with the Amerex Industrial Dry Chemical System must be U.L. Listed for use with natural gas or propane, be
held open by energizing an electrical solenoid and be wired through a microswitch and manual reset relay. Any field
wiring and connections involving the shutdown of electrical equipment or an electrical gas valve must be done by a
qualified electrician.
Power to the Electrical Gas Valve is run through the normally closed contact on a microswitch located in either the
MRM or ERM to the Manual Reset Relay and from the Manual Reset Relay to the Electrical Gas Valve. In a normal,
non -fire condition, current is allowed to flow to the solenoid on the Electrical Gas Valve, holding the valve open. In a
fire condition, when the suppression system actuates, the microswitch contacts will transfer, opening the normally
closed contacts in the Manual Reset Relay, interrupting the current to the gas valve and cause it to close.
Resetting the MRM (or ERM) and transferring the contacts back to a normal (normally closed) position will not
cause the Electrical Gas Valve to open. The Manual Reset Relay must be reset before current will flow to the valve
and cause it to open. A loss in electrical power, even temporary, will require someone to manually reset the relay
before the Electrical Gas Valve will open again.
Note: see wiring schematics on the following page.
MICROSWITCH APPLICATIONS:
One P/N 12524 Microswitch is installed in the Mechanical Release Module and Electrical Release Module. The
MRM and PRM is capable of supporting four total microswitches. Two additional switches may be added to the
ERM. The P/N 12524 microswitch may be used to perform a variety of output functions such as: sounding an
auxiliary audible or visual alarm signalling device, shutting down electrical appliances, or disrupting power to an
electrical gas valve.
RED: COMMON
YELLOW: N.O.
BLACK: N.C.
The P/N 18312 Alarm Signalling Microswitch (one installed) is used when it is required to be electrically connected
to a fire alarm system per NFPA 17 and NFPA 72 in a supervised, four -wire manner. It is designed to be mounted
in the Mechanical Release Module (MRM / MRM II) and the Pneumatic Release Module (PRM) only for the purpose
of initiating an alarm in a fire alarm system. All Microswitch connections are to be made outside the MRM / PRM in
an approved junction box.

6) Any electrical function must be wired in either series (Normally - Closed function) or in parallel (Normally -Open
function) through a microswitch in each MRM. This will ensure that the firing of either MRM will facilitate the
required function. �--�
7) A clearly visible sign or placard must be placed securely adjacent to each of the two MRMs with the wording
similar to the following: "This Releasing Control Head is One of Two Units. Both Units Must be Seviced
Together, in Conjunction with the Fire Suppression System ".
8) An audible device must be used with this system configuration, wired through microswitches of each MRM's, so
that the firing of either MRM will provide an audible signal.

9. Explosion Proof Pressure Switch:
Amerex P/N 16384 Explosion Proof Pressure Switch is used in hazardous locations, where standard electrical
microswitches are prohibited. It is designed to be installed in the distribution piping of any of the system's agent
cylinders. It must be installed within 12" of the Agent Cylinder Valve outlet with an inline tee. Place the switch on a
12" vertical section of /" pipe, in order to separate it from the flow of dry chemical, as shown below:
PRESSURE
