THE NEW MANUAL – WHAT IS NEW?
This NEW Restaurant Systems Manual carries a new part number, 20150, for it
is a combining of the two previous manuals, KP Manual PN 12385 rev. “A” and ZD
Manual PN 16640. The combining of the two manuals does not eliminate any of the
limitations of system requirements of the original two manuals, but strives to organize
the information into a comprehensive order with additional informative information for
greater clarity and understanding.
Some of the changes you will notice in the new manual are made to reduce cost
of inventory, printing, manufacturing, ordering and returns. The first item you will notice
is the change in nomenclature, KP 375 or ZD 375 Agent Cylinder Assemblies are now
referred to as a Model 375 Agent Cylinder Assemble. Now there is only one part
number per Model of Agent Cylinder Assembly. No longer do you have to order a
different part number for a KP or ZD Agent Cylinder Assembly nor do you have to stock
two cylinders the same size simply because one is for a KP system and one is for a ZD
system.
Closer examination of the new manual will reveal that the original configured
MRM required that you purchase a MRM and an enclosure (painted or stainless steel)
separately. The new MRM II is supplied pre-installed in an enclosure (painted or
stainless steel) ready to mount on the wall. The new MRM II incorporates the use of a
new ratcheting take up for the automatic detection line. The original MRM used a
manual take up method for the cable tensioning and was part number 11977. The
original MRM version is no longer in production, however if a replacement for an
existing unit is needed or if you are ordering a “Cabinet” enclosure (PN 11978) you can
still order part number 11977 as a replacement or to use in the “Cabinet” enclosure.
The part number now supplies a MRM II unit without the enclosure, but with the new
ratcheting take up. It is 100% interchangeable with the original MRM.
The new manual will still contain service and maintenance instructions for the
original style MRM. Anytime you see a heading that says MRM, it is referring to the
original style unit. If the information is good for both style units it will say MRM / MRM II.
The following arrangement, MRM / MRM II / PRM, indicates that the information is good
for all three units.
Due to the combining of the two manuals the following substitutions should be
used as follows:
KP Manual PN 12385 is superseded by Restaurant Manual PN 20150
ZD Manual PN 16640 is superseded by Restaurant Manual PN 20150
ZD 275 Agent Cyl. Asy. PN 17102 is superseded by Model 275 Agent Cyl. Asy PN 16921
ZD 375 Agent Cyl. Asy. PN 16650 is superseded by Model 375 Agent Cyl. Asy PN 13334
ZD 475 Agent Cyl. Asy. PN 17474 is superseded by Model 475 Agent Cyl. Asy PN 17397
KP/ZD 375 Mounting Bracket PN 16085 is superseded by 375 Mounting Bracket PN 17690

Amerex Restaurant Fire Suppression System (EX4658)
GENERAL INFORMATION
The Amerex KP / ZD Series Restaurant Wet Chemical Fire Suppression System is designed and has been
tested to provide fire protection for commercial cooking operations covering the hood, ducts, plenum and
appliances. Amerex Restaurant Fire Suppression Systems are a pre-engineered type as defined in NFPA
17A – Standard for Wet Chemical Extinguishing Systems. It is manufactured by the Amerex Corporation,
Trussville, Alabama.
It is essential that all installations of the Amerex KP / ZD Series Systems be performed in compliance with this
manual. Those individuals responsible for the design, installation, operation and maintenance of
the Amerex Restaurant Fire Suppression 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 exceeding limitations stated in this
manual will void all of the Amerex KP / ZD Series System listings.
LISTINGS:
The Amerex KP / ZD Series Fire Suppression Systems are a listed pre-engineered fire extinguishing systems.
The KP & ZD systems are listed with Underwriters Laboratories, Inc. – USA per UL 300 fire test specification;
Underwriters Laboratories of Canada, Inc. per ULC/ORD 1254.6 – 1995 and Loss Prevention Certification
Board – UK per LPS 1223 rev. B. The use of the STRIKETM panel and SRM releasing device is not ULC
Certified. Testing required for listings under these standards involve live fire tests under specific conditions
involving commercial kitchen hoods, ducts and appliances. Each test fire is allowed to reach its maximum
intensity before agent is discharged. Each test was repeated using both maximum and minimum piping,
variations in agent storage cylinder pressure to simulate maximum and minimum temperature
ratings. Duct fire tests were extinguished with fans off and fans on; dampers open and closed. Splash tests
for various appliances were conducted to assure that discharge of the agent would not cause excessive
splashing of hot grease to provide greater employee safety during commercial cooking operations.
UL Standard 300 introduces a series of tests byspecifically addressing the use of high efficiency fryers,
ranges, woks and the unique fire extinguishing challenges that these appliances present.
DESIGN:
The Amerex KP Series Pre-Engineered Fire Suppression Systems consist of mechanical and electrical
components to be installed by an Authorized Factory Trained and Certified Amerex Restaurant Fire
Suppression Systems distributor. The system is composed of an Agent Cylinder/Discharge Valve charged
with Amerex Kitchen Wet Chemical Agent and aMechanical Release Module (MRM or MRM II),
Pneumatic Release Module (PRM) or a STRIKETM panel / STRIKETM Releasing Module (SRM).The
quantity of detectors, fusible links, nozzles, corner pulleys, pulley tees and manual pull stations will vary
depending on kitchen 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 cooking appliances are required to be shut off
immediately. Electrical shutdown devices or suitable gas valves are referenced in this manual. Other
equipment such as audible/visual signaling devices can be added where required.
The Amerex Restaurant Fire Suppression System suppresses fire in commercial cooking equipment by
spraying Amerex Wet Chemical Agent in a pre-determined manner onto cooking appliances and into exhaust
ducts, filters and plenum areas. The primary means of fire suppression is either by saponification of surface
grease or by cooling the surface of oils and hot metal surfaces with fine droplets of agent, reducing the
temperature of the oil and appliance below the auto-ignition point.
Upon system discharge, the exhaust fans should be left on to aid in dispersal of the liquid suppressant that
results in cooling the plenum and duct. Any integral make-up or supply air should be automatically shut off
along with all cooking appliances. Some local Authorities Having Jurisdiction require exhaust fans to be shut
down by the fire suppression system. Check local fire codes, AHJ and Department of Health in the specific
area that the system is being installed for special installation requirements.
The Amerex Restaurant Fire Suppression System agent storage cylinders and cartridge shall not be installed
in environments below 32° For above 120° F (0° C to 49° C).

Amerex Restaurant Fire Suppression System (EX 4658)
GENERAL INFORMATION – ZONE DEFENSE SYSTEM
The Amerex KP and ZD SeriesPre-Engineered System consists of mechanical and electrical
components to be installed by an Authorized Factory Trained and Certified Amerex Restaurant Fire
Suppression Systems distributor. The system is composed of an Agent Cylinder Assembly charged
with Amerex Kitchen Wet Chemical Agent and a Pneumatic Release Module (PRM) or an MRM, MRM II
using a linear link detection network.
The system operates either automatically, if actuated by a rupture in the pressurized thermal responsive
tubing or by the separation of a thermal link or manually if actuated by a manual pull station. Upon system
operation, energy sources for the cooking appliances are required to be shut-off immediately. Electrical
shutdown devices or suitable gas valves are referenced in this manual. Other equipment such as
audible/visual signaling devices can be added where required.
The Amerex ZD and KP Series Systems use the same components and share the same UL Listings and
limits for the protection of the exhaust duct, plenum and dedicated appliance protection. They do not share
the same piping limitations or installation philosophy. This manual provides the unique limitations which apply
to a Zone Defense Fire Suppression System.
What isthe basic difference between a KP and ZD System Philosophy?
The Amerex Zone Defense System was developed for the kitchen that changes out it’s cooking appliances
frequently to accommodate the change in menu or cooks. The ZD System provides a detection system and
protection system which allows for the moving and rearranging of appliances without changing the fire
suppression piping or detection device locations. This is accomplished by using a detection network that will
detect a fire no matter where it occurs under the hood and will extinguish cooking appliances located
anywhere under the hood, as long as they are inside the “Zone of Protection”. Also the appliances must be
capable of being extinguished from overhead. Appliances such as upright broilers, salamanders, covered
tilting skillets, chain feed pizza ovens, etc. are all appliances that cannot be extinguished from overhead, but
require specific nozzles with specific aiming for the individual appliance. The use of a “back shelf” over
appliances also will block the application of agent from overhead nozzles and therefore requires the use of
“Dedicated Appliance Protection” for an appliance with a back shelf.
The Amerex Kitchen Protection Fire Suppression System differs from the ZD System in the manner in which it
protects appliances and detects a fire under the hood. The KP System uses individual “Dedicated Appliance
Protection” for each appliance under the hood requiring protection. A choice of the fire detection method may
be a standard thermal link network or one of the two linear detection networks. (PRM or Linear Fusible Link).
The KP &ZD Series Systems have their distinct application use in the field of kitchen protection. They both
provide superior protection from the hazards of commercial cooking.

Duct opening measuring 18”x 9” would have 54 perimeter inches [18 + 18 + 9 +9 = 54])
PLENUM:The space defined by the filters and the portion of the hood behind the filters.
PNEUMATIC RELEASE MODULE (PRM): This single hazard control mechanism supervises and controls
one Fire Suppression System. Proven, rugged mechanical components are reliably set into motion with a
simple linear pneumatic detection interface. The control mechanism interfaces with mechanical manual pull
station(s), actuation networks, mechanical gas valves, and offers electrical contacts for shutdown functions.
Refer to the Design and Installation Manual, P/N 16546 for further details.

PRE-ENGINEERED SYSTEM: Those systems having pre-determined flow rates, nozzle pressures and
quantities of agent. These systems have the specific pipe size, maximum and minimum pipe lengths,
flexible hose specifications, number or fittings and number of types of nozzles prescribed by a testing
laboratory. The hazards protected by pre-engineered systems are specifically limited as to type and
size by a testing laboratory based on actual fire tests. Limitations on hazards that can be protected by
these systems are contained in the manufacturer’s installation manual, which is referenced as part of
the listing.
“PUFF TEST” (or “AIR TEST”): A test to determine that the distribution network piping is clear. The
test is conducted by running nitrogen through the piping and confirming that all nozzles are clear.
PULLEY TEE: A device similar to a corner pulley except there is a change in direction on the cable
from two manual pull stations or two mechanical gas valves. It unites either two gas valves or two
manual pull stations to a single control point.
SALAMANDER BROILER:See upright broiler.
SAPONIFICATION: The reaction of fats and/or oils to alkaline materials, producing soap-like foam. Fire
extinguishing agents based on sodium bicarbonate, potassium bicarbonate, potassium acetate and potassium
carbonate will cause saponification when discharged onto hot grease. Rendered animal fat and oils containing
high percentages of saturated fat saponify better than cooking oils containing low percentages of saturated fat.
SERIES DETECTOR: Any detector located between the Mechanical Release Module (MRM or MRM II) and
the terminal detector.
STRIKETM: Electronic Control System (ECS) for use with KPTM Fire Suppression Systems. (Ref. UL File
S35485)
STRIKETM RELEASING MODULE (SRM): The STRIKETM Releasing Module is used to actuate the agent
cylinder discharge valve either automatically or manually by puncturing a nitrogen cylinder.
STRIKETM RELEASING MODULE (SRM), OEM: The SRM, OEM lacks the stainless steel enclosure and is
used in hood end cabinet or OEM installations.
SUPPLY LINE:That portion of the agent distribution network piping that runs from the agent cylinder
assembly outlet or distributor block to the first tee.
SUPPLY BRANCH LINE: All pipe and fittings leaving the first tee in the system and ending with the last
nozzle in the last nozzle branch line.
TERMINAL DETECTOR: The last detector (or only detector) in the detection network. It is at this point that
the cable for the detection network ends or is terminated.
TEST LINK: This device is used in place of a fusible link in order to easily test the detection network. The test
link is easily cut, simulating a fusible link separating under fire conditions. It is usually located on the terminal
detector and is used solely for test purposes.
UPRIGHT BROILER: A cooking appliance using intense radiant heat and conductive heat with the foot and/or
the radiant heat source not being limited for a horizontal mode. Most of these cooking appliances incorporate
a removable drip tray and may be used specifically for holding or warming foods.
VENT CHECK: Adevice installed in the actuation network that is used to safely relieve pressure and to
prevent a slow, unwanted build-up of pressure in the actuation network.
ZONE of PROTECTION – A horizontal foot print below and within the perimeter of the hood, in which the
cooking appliances are to be positioned. The discharge nozzles within the “Zone of Protection” are spaced at
pre-determined intervals to provide protection for eligible appliances within the “Zone of Protection” without the
need for re-aiming or repositioning of nozzles. An exception to this practice is for dedicated appliances such
as the upright broiler. Dedicated appliances require appliances specific nozzles protection, which will require
further review after movement of the appliance for possible re-aiming or repositioning of nozzle(s).
