Cylinder Tank Assembly
The TANK Fire Suppression cylinder assembly (p/n 87-300001-001) uses a mild steel cylinder, conforming
to 4BW250 DOT & 4BWM-17 TC specifications, and a nickel-plated brass valve with pressure indicator
gauge. Each valve includes a Schrader port for connection to the primary actuator hose (for primary
cylinders) or the supervisory pressure switch (optional for secondary cylinders).
Each cylinder assembly is factory-filled with TANK liquid fire suppressant and pressurized to 200 PSIG
(1379 kPA) at 70°F (21°C). Each cylinder supports up to 5 nozzles for a total of 20 flow points.
Figure 3 - Cylinder Tank Details
The pressure of a cylinder will vary with the ambient temperature, as detailed in Table 1. The gauge
indicator (shown in Figure 3) should be in the acceptable ‘green’ range for a cylinder that is properly
pressurized and within the listed operating temperature range. For a cylinder at the lowest listed operating
temperature of 32°F (0°C), the pressure gauge should read approximately 175 psig (the lower end of the
green range). For a cylinder at the highest listed operating temperature of 130°F (54.4°C), the pressure
gauge should read approximately 225 psig (the upper end of the green range).

Cylinder Tank and Actuator Bracket
Each cylinder assembly is secured to a factory-installed cylinder bracket in the cabinet (p/n TFS-
UCTANKBRACKET). The cylinder is secured to the cylinder bracket via three (3) stainless steel straps.
The cylinder bracket also includes a platform for securing a primary actuator kit or secondary valve
actuator during shipping and maintenance procedures.
Figure 4 - Cylinder Tank and Actuator Bracket
Discharge Adapter
The discharge adapter (p/n WK-283952-000) is used to connect the TANK Fire Suppression cylinder valve
outlet to the agent distribution pipe network. The 1/2-inch NPT internal thread of the discharge adapter
outlet is connected to the supply line via an elbow and adapter.
The discharge adapter uses an O-ring (p/n WK-108019-000) at the valve port to eliminate leaks during
discharge.
Figure 5 - Discharge Adapter
7
Nozzles
The Overlapping Female Nozzle(s) (p/n OL-F) are used for plenum, duct, and dedicated appliance
coverage (e.g., salamanders, upright broilers, chain broilers, and appliance with upright obstructions). The
nozzles include a cap (p/n 3074-1-1). The cap prevents contamination from entering the pipe network and
is designed to pop-off upon system discharge, allowing the agent to flow to the protected hazard area.
Refer to “Duct and Plenum Protection” on page 14.
Figure 6 - Fire System Nozzle
Primary Actuator Kit (PAK)
The Primary Actuator Kit (PAK) (p/n 87-300030-001) is installed on each primary cylinder assembly to
pneumatically open the cylinder valve and provide actuation pressure for up to three secondary valve
actuators.
The PAK consists of a pneumatic actuator, 24V DC solenoid valve, check valve, primary actuator hose,
and associated fittings.
Upon automatic or manual system actuation, the control panel sends a momentary 24V DC release signal,
opening the PAK solenoid. Pressure from the primary cylinder is passed through the solenoid and check
valve, into the primary actuator (actuating the primary cylinder), and into the interconnected secondary
valve actuators (actuating the secondary cylinders).
The primary actuator has a 1/8” NPT inlet port for connection to the primary system cylinder, and a 1/8”
NPT outlet port for connection to the secondary cylinder actuation line or actuation plug for single cylinder
system. The primary actuator includes a piston with a spring-loaded locking pin which locks the piston in
the discharge position, ensuring complete discharge of the cylinder contents.
Figure 7 - Primary Actuator Kit
NOTE: The primary supervisory pressure switch is standard on primary tanks. Secondary
supervisory pressure switches are optional on secondary tanks.

Secondary Valve Actuator (SVA) and Hose
A Secondary Valve Actuator (SVA) (p/n 87-120042-001) is installed on each secondary cylinder assembly
to pneumatically open the cylinder valve(s). The SVA has 1/8” NPT inlet and outlet ports for connection to
the system actuation line via the SVA hose. All secondary hoses require a 1” minimum bend radius. The
SVA includes a spring-loaded locking pin that locks the actuator piston in the discharge position, ensuring
complete discharge of the cylinder contents.
Figure 8 - Secondary Valve Actuator
Supervisory Pressure Switch
The primary and (optional) secondary supervisory pressure switch (p/n 87-300040-001) are preset to
alarm at a cylinder pressure of ~10% below the lowest operating system pressure of 175 psig (pressure at
the lowest listed operation temperature of 32°F). The supervisory pressure switch uses a diaphragm
sensor to detect pressure changes. At the predetermined set point, the unit actuates a SPDT snap-acting
switch, converting a pressure signal into an electrical signal. The supervisory pressure switch can be used
on primary and/or secondary cylinders. For primary cylinders, the pressure switch is mounted on the
primary actuator kit. For secondary cylinders, the pressure switch is mounted on the Schrader fitting
installed on the cylinder valve.

Gas Shut-Off Valves
Electric gas shut-off valves are used to shut down the flow of fuel gas to the kitchen appliances upon
actuation of the TANK Fire Suppression system. An energized solenoid is used to hold the gas valve in the
open position. The solenoid closes the valve when de-energized via the output relay of the control panel.
The gas valves are available in 120V AC and 24V DC, ranging from 3/4” to 3” pipe sizes (Table 2).
Electric Remote Manual Release
An electrically operated manual release that is listed must be used with the TANK Fire Suppression
extinguishing system. The electric remote manual release is used to actuate the TANK Fire Suppression
extinguishing system manually and must be properly located and supervised in accordance with NFPA
17A and NFPA 96.
Firestat (Heat) Detector
The Firestat (Fenwal Detect-a-Fire) is a listed electric thermal detector available in a variety of temperature
settings and used to actuate the TANK Fire Suppression extinguishing system automatically. When a
Firestat senses a temperature higher than its setpoint, the Firestat contacts will close and energize the
TANK Fire Suppression system via the control panel.

INSTALLATION
The extinguishing system consists of pressurized agent storage cylinders tanks, agent distribution piping,
valve actuators, supervisory pressure switches, and agent discharge nozzles. All primary components and
piping are factory-installed. Systems may be comprised of single or multiple cylinders depending on the
size and configuration of the protected hazards.
Cylinders can be piped independently, or manifolded. On two-cylinder systems, the cylinders will be in a
manifold configuration. Refer to Figure 35 on page 33 for a two-cylinder system example. On three-
cylinder systems, two cylinders will be in a manifold configuration and one independent. On four-cylinder
systems, there will be two separate manifolds.
In a fire condition or upon manual actuation, the solenoid valve is opened, allowing pressure from the
primary cylinder to flow to the primary and secondary cylinder valve actuators, opening the cylinder valves
and discharging liquid fire suppressant to the protected hazard areas.
Figure 11 - Cylinder Assemblies
Cylinder Tanks
Cylinders are typically factory-installed, pressurized, and may be located anywhere within the hood end
cabinet. Additional cylinders may be field installed, as needed, in the additional hood end or wall mount

Supervisory Pressure Switch
A supervisory pressure switch will always be located on the primary cylinder by the Primary Actuator Kit
(PAK). For secondary cylinders, this is an optional component that may be added on. For primary
cylinders, the pressure switch is mounted on the primary actuator kit. For all secondary cylinders, the
pressure switch is mounted on the Schrader fitting on the cylinder valve.
1. Remove cap from applicable Schrader fitting.
2. Thread the switch onto the Schrader using the brass wrench flats only.
Figure 16 - Supervisory Pressure Switch Installation
NOTE: Pressure switches do not contain any field replaceable parts. Refer to applicable control
panel manual for wiring of the supervisory pressure switch. Wire in accordance with local and
national electrical codes.
The electrical rating is rated to 5A resistive and 3A inductive at 30V DC; gold flashing over silver contact for
loads down to 1mA at 24V DC.
Supervisory pressure switches are connected in series to the control panel supervisory input.
WARNING!
Proof pressure (*) limits stated on the nameplate must never be exceeded, even by surges in the
system. Occasional operation of unit up to proof pressure is acceptable (e.g., start-up, testing).
Continuous operation should not exceed the designated over range pressure (**).
*Proof pressure - the maximum pressure to which a pressure sensor may be occasionally
subjected, which causes no permanent damage (e.g., start-up, testing).
**Over Range Pressure - the maximum pressure to which a pressure sensor may be continuously
subjected without causing damage and maintaining set point repeatability.
WARNING!
Disconnect all supply circuits before wiring pressure switch. Electrical ratings stated in literature
and on nameplate must not be exceeded - overload on a switch can cause failure on the first cycle.

Duct and Plenum Protection
The TANK Fire Suppression extinguishing system for duct and plenum coverage can be provided by
independent fire suppression tanks and piping or integrated with the fire suppression tanks and piping
used for protection of the appliances. Max of 5 nozzles per TANK for duct and plenum coverage only.
Plenum Protection
The nozzle(s) (page 7), are used to protect plenum areas in both single bank and V-bank plenum
configurations. The nozzle will protect up to a 4' wide x 10' long plenum section. For larger plenum areas,
additional nozzles are added as required, with each nozzle protecting no more than a 4' wide by 10' long
plenum section. Nozzles may be installed pointing in the same direction, and/or at opposite ends of the
plenum, pointing toward each other. The nozzles must not be installed back-to-back when protecting
plenum areas. When positioned at the end of the plenum, nozzles must be installed from 0 to 6" into
plenum.
If the riser is not centered on the plenum, the plenum nozzle is placed on the side of the plenum closest to
the riser.
The nozzle locations for plenum protection are shown in Figure 17 and Figure 18.

Ventilation Exhaust and Dampers
The TANK Fire Suppression extinguishing system can be used with the exhaust fan either on or off when
the system is discharged. It is recommended that the exhaust fan remain on at the time of discharge to aid
in the removal of smoke, gases, and other airborne materials from the hazard area in the event of a fire. If
the Authority Having Jurisdiction (AHJ) requires that the damper closes in the event of a fire system
discharge, the system designer shall provide for protection downstream of the damper in compliance with
NFPA 96, local codes, and/or as approved by the AHJ.
Electrostatic Precipitators (ESP)
An Electrostatic Precipitator (ESP) is designed to remove smoke and other airborne contaminants from the
air flowing through the exhaust ductwork as a means of pollution control. Exhaust ductwork using ESPs
requires Overlapping Male nozzle(s) (p/n OL-M [previously 3070-3/8HH-10-SS]) upstream, before the
ESP. Distribution piping to the nozzles must not interfere with the function of the ESP unit.
A Pollution Control Unit (PCU) and/or Electrostatic Precipitator (ESP) covered with this fire system can
utilize up to 12 nozzles per tank.

Appliance Protection
The TANK Fire Suppression system utilizes both overlapping and dedicated nozzle appliance coverage,
depending on the type of cooking appliance(s) requiring protection. For dedicated and overlapping nozzle
information, refer to “Nozzles” on page 7.
Overlapping appliance coverage allows a given area under the hood, defined as the hazard zone, to be
protected by overlapping nozzles. Nozzles are evenly spaced at the same height and alignment (front-to-
back) relative to the hazard zone.
Dedicated appliance protection utilizes a nozzle, or nozzles, for protection of an individual appliance.
Overlapping, dedicated appliance, plenum, and duct protection may be incorporated in a single pipe
network on the TANK Fire Suppression extinguishing system, as long as the number of nozzles per tank
does not exceed five.
The following sections detail the different nozzle coverage and placement parameters for overlapping and
dedicated nozzle appliance protection methodologies. Double row coverage is allowed for TANK.
Overlapping Appliance Protection
A single hazard zone utilizing overlapping coverage is 30” deep, by the total length of the cooking surface
of the protected appliances. The cooking surfaces of all appliances protected by overlapping nozzles must
be located within the defined hazard zones. Cooking appliances eligible for overlapping protection are
outlined in Table 3 on page 19. The lowest and highest cooking surfaces will determine the height of the
fire suppression nozzles. All overlapping nozzles must be mounted at the same height in a single hazard
zone.
For applications where overlapping protection cannot be used, such as an upright boiler, dedicated
appliance protection must be used.

Appliance Coverage
Table 3 illustrates the maximum permitted cooking surface dimensions of each appliance that can be
protected within a single overlapping zone. It is important to note that the cooking surface (area requiring
protection) is different than the total appliance size.
Notes:
1. All dimensions shown are based on overlapping protection.
2. All dimensions and areas shown reference the cooking surface of the appliance, which is typically
smaller than the outside dimensions of the appliance itself.
3. For multi-vat fryers, no single fryer module (vat & drip board) can exceed the above limitations.
4. Protection for tilt skillets and braising pans are to be based on the coverage parameters provided for
fryer protection. Tilt skillets should be placed at the back of the hazard zone. Tilt skillet coverage must
not interfere with the edge of the nozzle discharge pattern.
5. All appliance hazard surfaces must be located within the hazard zone.
6. Smaller appliances can be positioned anywhere in the zone (e.g., moved left, right, forward, or
backward, provided the cooking hazard does not extend beyond the perimeter of the zone).
7. When the depth of the appliance exceeds maximum cooking hazard dimensions, a second row of
nozzle coverage should be added.
8. Deep Fat/Industrial Fryer/Tilt Skillets over 14” wide and up to 34” max depth will be overlapping with 4
nozzles per tank, 30” spacing. Max oil capacity: 24.75 gallons.
9. Nozzle height(s) for fryers should be taken from the fryer’s minimum level indicator.
Figure 22 illustrates the placement of nozzles for TANK Fire Suppression overlapping protection.
Appliances denoted with an (*) require dedicated coverage. Refer to “Upright Broiler/Salamander
Protection” on page 25 and “Appliance with Shelf” on page 26 for details.

Overlapping Protection
Standard overlapping protection is 5 nozzles (20 flow points) at 36” spacing. Exceptions are noted below.
All overlapping nozzles must be spaced no more than 12” from each end of the appliance, and located at
the centerline of the 30” hazard zone (front to back), at the same height, and aimed straight down. The
nozzle height must be 35” to 50” above the appliance cooking surface, except for woks, where the height is
measured 3 inches below the top rim of the wok. The nozzles must be positioned along the total hazard
zone length to allow protection of each appliance in the hazard zone.
Exceptions to standard overlapping protection:
• Large/Industrial fryers over 14” wide, 4 nozzles at 30” nozzle spacing per tank.
• Woks larger than 24 inch diameter, 4 nozzles at 30” spacing per tank.
• Appliance with shelves, 4 nozzles at 36” spacing per tank.
• Solid Fuel Appliances, 3 nozzles at 24” spacing per tank.
Refer to “Coverage Exceptions” on page 20 for more information.
Overlapping Coverage - Group Protection
Overlapping protection provides coverage for a continuous hazard zone, with all nozzles at consistent
position (i.e., zone centerline), spacing, and height.
When there is an area within a hazard zone for which continuous overlapping coverage is not applicable,
the overlapping protection zone must be ended, and a new zone started for the new group of appliances.
Examples where continuous protection is interrupted, include a counter, storage or prep area, appliance
not requiring protection (e.g., enclosed oven) or an appliance requiring dedicated appliance coverage.
The examples on page 23 through page 24 provide details of group overlapping protection for interrupted
zones. This section illustrates the methodology for defining when a new hazard zone is required, as
described above. For specific overlapping coverage parameters (e.g., nozzle spacing and height
requirements).
23
Group Protection Example 1 – Appliance line separated by unprotected space.
End nozzles must be located 12” or less (horizontally) from the end of the hazard zone. Standard
overlapping nozzles must be spaced no further than the maximum allowed interval 36” on center. Refer to
“Coverage Exceptions” on page 20 for more details on coverage exceptions.
Figure 24 - Example 1
NOTE: Overlapping nozzle spacing and height requirements are based on the appliances protected
for each individual zone. Nozzles must always be located at the start and end of each zone, no
more than 12” from the end of the hazard zone (edge of 1st/last cooking appliance surface). Refer
to “Overlapping Appliance Protection” on page 18. Zones cannot overlap.

Appliance with Upright Obstruction
Salamanders/Cheesemelters have specific coverage requirements, unlike appliances with an exposed flat
cooking surface, these appliances have an internal cooking surface and only have a small opening in the
face or end of the appliance.
To cover the internal hazard posed by these appliances, an Overlapping Female (OL-F) nozzle is placed at
the opening and aimed to the opposite rear corner of the appliance. The nozzle must be branched off one
of the nozzle drops with a tee and piped to the appliance opening. No more than two nozzles can be
utilized for a single drop. Should the cooking surface of the appliance exceed 1050 in2, an additional
nozzle will be required on the opposite side of the appliance for added fire protection, refer to Figure 30.
Salamander/Cheesemelters should follow appliance coverage for “Upright Broiler/Salamander
Protection” on page 25.
An additional nozzle must be piped from a nozzle drop nearest the appliance, to cover the hazard
underneath the salamander. This nozzle is to be aimed at the centerline of the hazard zone, a minimum of
35”-50” away. Overlapping coverage is required for appliance specific coverage.
All dimensions fixed unless otherwise noted (e.g., min/max).
1. Pipe and fittings above the hood will be 1/2” copper pipe/Pro-Press, Grade L copper tubing/fittings.

The following Salamander/Cheesemelter example does not require overlapping protection. Unlike
appliances with an exposed flat cooking surface, these appliances have an internal cooking surface and
only have a small opening in the face or end of the appliance.
To cover the internal hazard posed by these appliances, a nozzle must be placed at the opening and
aimed to the opposite rear corner of the appliance. No more than two nozzles can be utilized for a single
drop. Should the appliance length exceed 36” or have an area over 1050 in2, an additional nozzle will be
required on the opposite side of the appliance for added fire protection, refer to Figure 31.
Nozzles covering Cheesemelters/Salamanders placed above an appliance can be branched off from
existing overlapping nozzles or use dedicated nozzle protection. Appliance with Overhead Salamander
equipment type will use dedicated nozzle protection. This nozzle is to be aimed at the centerline of the
hazard zone, a minimum of 35”-50” away (DIM A).
All dimensions fixed unless otherwise noted (e.g., min/max).
1. Pipe and fittings above the hood will be 1/2” copper pipe/Pro-Press, Grade L copper tubing/fittings.
2. Pipe and fittings inside the hood capture volume will be 3/8” NPT stainless steel or chrome-plated
black iron. No sleeving permitted.
3. Appliance coverage piping to be field piped - unions, elbows, and nozzles factory provided.
4. Additional nozzles may be utilized for supplemental appliance specific protection. No more than two
(2) nozzles may be used on a single drop.
5. Appliance drop fittings may be sealed with pipe dope or Teflon tape.

Gas Shut-Off Valves
The electric gas valve is held open in the energized state, and closes when de-energized via the output
relay of the control panel. A listed manual reset relay is required to ensure manual reset prior to fuel being
restored in accordance to NFPA17A.
Gas valves (Figure 36) are designed to shut off the flow of gas to the kitchen appliances in the event of fire
system activation. Electric gas shutoff valves must be installed with an upstream strainer to prevent debris
from prohibiting gas valve function. New pipe, properly reamed and cleaned of metal burrs, should be
used. Proper care is needed to ensure that the gas flow is in the same direction as indicated on the gas
valve and strainer. Do not over-tighten pipe connections. Apply pipe dope to the male threads only. If
necessary, install a drip leg in the gas line in accordance with the Authority Having Jurisdiction (AHJ).
120V AC gas valves 3/4” - 2” can be mounted with the solenoid in any position above horizontal.
120V AC gas valves 2-1/2” - 3” must be mounted with the solenoid vertical and upright. The pipe must be
horizontal.
All 24V DC gas valves must be mounted with the solenoid vertical and upright. The pipe must be
horizontal.
Proper clearance must be provided in order to service the strainers. A minimum of 4” clearance distance
must be provided at the base of the strainer.

Hood Riser Sensor Replacement
The following instructions are for replacing a hood duct stat or fire stat located in the riser.
NOTE: Make sure the fire system is deactivated and all controls are powered down before servicing the
unit. Service should only be performed by trained personnel.
1. Locate faulty sensor in hood riser. Remove the hood filters to access from the hood plenum.
2. Determine the location of the sensor’s lead ends. This will either be on the top of the hood, in the junction box
which has conduit routed to the riser, or in the electrical control package that is mounted on the hood (if it is a
stand-alone hood).
3. Access the sensor’s lead ends and remove Wago connectors. Attach a fish tape (or pulling rope) to the lead
ends.
4. Unscrew the sensor from the quick seal in hood plenum. Pull leads completely out, pulling the fish tape until
exposed.
5. Attach replacement sensor to fish tape and pull back through conduit until lead ends are back in the original
location.
6. Replace Wago connectors on the new sensor’s lead ends.
7. Twist new sensor counterclockwise, 2-1/2 turns to pre-tension wires. Thread sensor in riser quick seal (using
Teflon tape on threads).
8. Replace hood filters.
9. Power up the system to test functionality.

Fire Protection Manual Actuation Device
Figure 39 - Activation Device
The push/pull station (Figure 39) is a remote manual actuation device to activate
the fire system. This remote manual actuation device (push/pull station) contains
one set of normally open contacts and mounts to any standard single gang junction
box. When the front button is pressed, the electrical connection to the fire system
is completed, thus activating the fire system.
The remote manual actuation device (push/pull station) should be mounted at a
point of egress and positioned at a height determined by the Authority Having
Jurisdiction (AHJ). This position is usually 10 to 20 feet from hood and 42 to 48
inches above the floor. Multiple remote manual actuation devices (push/pull
stations) are acceptable to use in the fire system and are wired in parallel per the
electrical schematic. The remote manual actuation device (push/pull station) is
reset by twisting the push-button clockwise until the internal latch is released.
The clear protective cover must be installed to protect the device from accidental
activations. This cover is provided as part of the manual actuation device. Below are the part numbers for the
devices and replacement parts (Table 10).
Note: When connecting the wires to the push/pull station, do not twist the wire ends together. Insert each
wire on the opposite side of the screw.
Trouble Input Wiring
Trouble contacts and supervision switches from each device should be connected to the trouble input of the
building fire alarm panel to indicate a trouble condition.

Fire Protection System Printed Circuit Board
The fire protection system printed circuit board (PCBCORE) is a microprocessor-based controller that
provides all the necessary monitoring, timing, and supervision functions required for the reliable operation
of the fire system. Under normal conditions, the “Fire System Activated” light is flashing one brief flash
every 3 seconds, indicating the system is armed and ready. If a fault is detected anywhere in the system,
an audible alarm will periodically sound, and the “Fire System Activated” light will flash a fault code to
indicate the fault that was detected. This fault code consists of a series of flashes followed by a pause.
Simply count the number of flashes between the pauses and refer to the chart below to find the cause of
the fault. Any fault is extremely important and must be corrected and rectified immediately to ensure proper
operation of the fire system.
The connections for building fire panels are located at AL1 and AL2 as dry contacts.
NOTE: When a CORE board is connected to an ECPM03 board, if a fire condition happens, the
“Last Fire Info” will be stored on the ECPM03 screen. “Last Fire Info” will be available on CASLINK
as well.

Electrical
Before connecting power to the control package, read and understand the entire section of this document. As-built
wiring diagrams are furnished with each control package from the factory and are either attached to the door of the
unit or provided with the paperwork packet.
Electrical wiring and connections must be made in accordance with local ordinances and the National Electric
Code, ANSI/NFPA70. Verify the voltage and phase of the power supply, and the wire amperage capacity is in
accordance with the unit nameplate.
ATTENTION: LOW-VOLTAGE DC OR SIGNALING WIRE SHOULD BE ROUTED IN SEPARATE CONDUIT
FROM ALL AC VOLTAGE SOURCES.
1. Always disconnect power before working on or near this equipment. Lock and tag the disconnect switch or
breaker to prevent accidental power-up.
2.There are multiple electrical connections required for this control. 120V AC should be wired to terminals H1
and N1. If the hood is equipped with a separate light circuit, 120V AC should power this circuit per the as-built
schematic. H1 and N1 should not be connected to a shunt trip breaker.
3. Verify that the power source is compatible with the requirements of your equipment. The system wiring
schematic identifies the proper phase and voltage of the equipment.
4. Before connecting the control package to a power source, verify power source wiring is de-energized.
5. Secure the power cable to prevent contact with sharp objects.
6. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces, or
chemicals. Release solenoid cables must not come in contact with hood surfaces.
7. If the control package is a wall-mount system, a duct mounted temperature sensor will need to be wired. The
temperature sensor must be wired to terminal blocks, as indicated on the wiring schematic.
8. If the system contains additional firestats, they must be wired into the supervised loop.
9. If the control is a wall-mount system, the hood lights wiring will need to be wired to terminals “B” and “W.”
Verify connections on wiring schematic.
10. Before powering up the system, make sure that the interior of the control package is free of loose debris or
shipping materials.
11. If any of the original internal wire supplied with the system must be replaced, it must be replaced with type
THHN wire or equivalent.
12. All field-supplied wire for the optional fire system release solenoid or firestat must be high temp wire rated for
842°F minimum (#441601C6.FE9 White and #441601C6.FE0 Black).
13. The battery must be plugged into the connector labeled J1 on the electrical board (PCBCORE) after wiring is
complete.
14. All gas appliances under the hood must shut down in the event of an AC power loss. All electric appliances will
shut down on building power loss.
15. It is recommended to use Belden #6320UL, 18 Gauge, plenum-rated wire for the supervised loop that does not
come in contact with the hood. It is recommended to use Belden #88760 for the fire system interlock network
and CAT-5 for Modbus communications.
16. All exterior wiring connections to the PCU must be run inside liquid tight conduit. This includes the supervised
loop and airflow switch wiring.
IMPORTANT!: The battery backup for the fire protection system produces output power even when main
power is disconnected from system. When performing major electrical service to the control, the battery
backup must be disconnected then reconnected before commissioning.
WARNING!!
Disconnect power before installing or servicing control. High voltage electrical input is needed for this
equipment. A qualified electrician should perform this work.
44
Wire Ampacity Rating
The load current rating and the over-current protection for conductor types shall not exceed 15 amperes for 14
AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum after any
correction factors for ambient temperature and number of conductors have been applied. Refer to Table 11.
Distance Limitations
Wiring connections to remote fire protection system(s) must use shielded twisted pair wire. The maximum length of
this connection is 1000 feet.
Wire size is an important consideration when making the connections between the fire protection system control
package and a gas valve. Refer to Table 12 for maximum wiring distance between the system and remote gas
valve.
Fire Alarm Contacts
The fire protection system is equipped with normally open contacts that can be connected to the premise Fire
Alarm Control Panel (FACP) (terminals AL1 and AL2). Refer to Figure 42 for wiring reference. During a fire
condition, the contacts will close and trigger the premise FACP to initiate a general fire alarm.

Fire Group
Fire Groups are for the purpose of using multiple CORE controlled fire systems and grouping specific fire systems
together. This will allow the user the ability to assign different zones for independent activation.
In order to set a fire group, you will need to set the CORE board DIP switches as shown in Table 13:
Note: Every panel with matching fire group settings (DIP switches 6 and 7) will activate simultaneously in a
fire condition.
Figure 43 shows an example of different zones on separate fire groups, but still connected via the interlock
network. In the example, when 2 Fire groups (01 and 02) are assigned on the CORE boards, and if a fire condition
exists in any one group, it will NOT activate the other fire group. However, both are connected to the same
interlock network.
• Fire Group 01 CORE board DIP switch setting will be set to: Switch 6 Open and Switch 7 Open.
• Fire Group 02 CORE board DIP switch setting will be set to: Switch 6 Closed and Switch 7 Open.
Refer to “Typical DIP Switch Arrangement” on page 57 for setting multiple CORE controlled fire systems.

Fire Protection System Supervised Loops
The supervised loops are integral to proper operation and activation of the Fire Protection System. All systems
have two supervised loops; each loop consists of two conductors, one positive and one negative. One loop is
dedicated to all sensors, while the other is dedicated to all manual actuation devices (push/pull stations). The
supervised loop connections are located at the front edge of the hoods for accessibility. Connections beyond the
hood, like the connections at the manual actuation device, must be made with a plenum-rated wire. It is
recommended to use a two-conductor Belden 6320UL, 18 AWG, wire, or similar for these connections. Refer to
Figure 44 for supervised loop details.
• Connections to the firestat will use two Wago connectors. One for an incoming loop and one for an outgoing
loop.
• Flexible metallic conduit is used to route the wiring that connects the firestat to the remote loop junction box.
Secure conduit to hood hat channel when possible.

OPERATION
The TANK Fire Suppression extinguishing system is electrically operated via the applicable fire alarm
control panel. The system can be activated automatically via an electric thermal detector or manually via a
remote manual actuator. The extinguishing system is electrically operated via the PCBCORE control
board. The system can be activated automatically via a Firestat or manually via a remote manual actuator.
Since the TANK Fire Suppression extinguishing system is electrically operated, the applicable fire alarm
control panel requires AC input power with a battery backup system. Reference the applicable control
panel manual for wiring and compatibility.
When one of the system’s Firestat(s) detectors senses a temperature hotter than its internal set-point (e.g.,
in the event of a hood fire), or when a remote manual actuation device (push/pull station) is pushed, an
electric signal is sent to the tank-based fire protection release solenoid via the fire alarm control panel
releasing circuit. The electric release solenoid is energized, allowing pressurization of the pneumatic
actuator(s). The actuator’s plunger(s) will depress into the tank valve body, releasing agent to flow to the
hood duct, plenum, and appliance nozzles.
When the fire extinguishing system is activated, the applicable fire alarm control panel simultaneously
shuts down all gas and electric appliances under the protected hood(s), shuts down make-up air and/or
exhaust where applicable, and activates the building fire alarm where applicable.
The electrically operated fire system requires a battery backup system. In the event of a loss of building
electrical power, all gas and electric appliances under the hood must be electrically interlocked to shut off.
This is achieved via a gas valve relay and/or a shunt trip breaker. The battery backup will automatically
energize upon a loss of power. The battery backup will monitor the fire system circuit for up to 24 hours
and be able to operate the fire system circuit for a minimum of 30 minutes. Once power is restored, the
battery will automatically recharge.
A means of manual reset is required for shut-off devices to ensure manual reset prior to fuel or power
being restored in accordance with NFPA 17 and NFPA 96. The electric gas shut-off valve is used in
conjunction with a UL/ULC listed manual reset relay, refer to “Gas Shut-Off Valves” on page 36.
Test Mode Overview
The fire protection system has an integrated option for testing. This test mode, when active, will disable the
release solenoid and prevent the fire extinguishing agent from spraying on the appliances. It will allow
activation of the fire system, audible alarm, shunt trip breaker (if applicable), and shut down of appliances
via gas valve reset relay.
All additional PCBCORE controlled packages that are attached to the system must be in “Test Mode.” This
includes additional fire protection systems, Pollution Control Unit with CORE, and other hood-mounted
CORE controlled protection systems.
Please note that the appliances must be started before test mode is entered on any PCBCORE protection
package for proper demonstration of this function. If the fire protection system is left in “Test Mode” for
more than 15 minutes, the appliances will shut down. This is to prevent cooking operations from occurring
while the appliances and ventilation system are not protected.
49
Reset Overview
There are multiple actions required to reset the fire system. The following must be completed by a
Certified Fire System Technician.
1. The duct firestat must be cooled below its internal set point.
2. The remote manual actuation device (push/pull station) must be reset by twisting the button clockwise
until it resets.
3. Press the “Push To Reset Fire System” button.
4. Reset the pneumatic actuators (PKA, SVA), refer to “Disconnecting Service Cylinder Tank/Re-
arming System” on page 60.
Note: The firestat must be cool, and the remote manual actuation device (push/pull station) must
be reset for this button to work.
The fire system must be re-commissioned per the manufacturer’s recommendations and guidelines by an
authorized fire system distributor and/or authorized service agent.
After a fire, full inspection by a certified professional must be conducted prior to restarting the fire system.

Appliance and electrical shut down is achieved via the applicable fire alarm control panel relay, in
conjunction with UL/ULC listed enclosed industrial control equipment or magnetic contactors of
appropriate rating. These must be used in conjunction with a UL/ULC listed manual reset relay, refer to
Figure 47. All wiring is to be in accordance with the applicable manufacturer’s instructions for the fire alarm
control panel, gas shut-off valve, manual reset relay, and contractor supplied shut-off devices. All wiring
must be in accordance to NFPA 70 and the Authority Having Jurisdiction (AHJ).
When a building fire alarm system is present, the fire alarm control panel must be connected in accordance
with the NFPA 72 such that the actuation of the TANK Fire Suppression extinguishing system also
activates the fire alarm. Reference the applicable control panel manual for wiring and compatibility.

Battery Backup
Figure 48 - Battery Backup
The fire protection system contains a battery backup. During a power loss,
the “Fire System Activated” light will flash 11 times between pauses
indicating the power loss.
The batteries must be replaced every 2 years, from the date of fire system
commissioning. Part number PS-1270-F2, two are required. Although the
batteries are hot-swappable, which means they can be replaced while
there is input power to the control, for your safety, all sources of power
must be removed from the control before replacing the batteries. To
replace the batteries, unplug the battery cable from the J1 connector on
the electrical board (PCBCORE). Then remove the retaining strap holding
the batteries in place. Remove the batteries from the cabinet. Transfer the
fuse and cable set from the old batteries to the new batteries being
extremely careful to observe the RED and BLACK lead and terminal
colors. Reinstall the batteries in the cabinet and reconnect the battery plug
to J1. The batteries are lead-acid type and are recyclable; please
dispose of the old batteries properly.
During extended periods of inactivity where the fire protection system will
be without AC power for more than 2 days, such as a shutdown or natural
disaster, it is best to decommission the fire system by disconnecting the
batteries. This will prevent any damage to the batteries through complete
discharge. When the system becomes active again, commission the
system by reconnecting the batteries and allow the batteries to charge for
48 hours.
Power Supply Adjustment
Figure 49 - Power Supply
To properly charge the batteries, the power supply must be adjusted to
output 27.5V DC. This can be checked with an accurate digital voltmeter
placed across Terminals H1D and N1D. To adjust the output voltage,
place a small flat-bladed screwdriver into the yellow dial. Turn the dial
clockwise, this will increase the voltage.
Important!!
The battery backup system requires that the batteries be changed every 2 years, from the date of fire
system commissioning, maximum. Failure to do this will result in a void in product reliability and may
cause severe damage to facility due to loss of fire protection.

Fire Protection System Firestat
The Firestat (“Firestat Installation Details” on page 37) is a device installed in the riser of the hood, at the duct
connection, that measures temperature. The standard temperature setting is 360°F. Depending on heat produced
by appliance, a higher rated temperature Firestat will be required. If a temperature higher than the setpoint is
sensed, the Firestat contacts will close and energize the electrical control board. The fire system will activate.
The Firestat has 2 black wires and 2 white wires. These wires must be connected to the supervised loop. Use high-
temperature wiring when installing Firestat components. Wago connectors (part number: 221-412) must be used.
Multiple sensors are wired in parallel in the supervised loop. The Firestat may be installed on the opposite side of
the quick seal for access in the duct.
Non-Solid Fuel Appliances (Rated 450°F)
Non-solid fuel appliances rated for 450°F will not require additional firestats, regardless of the configuration and
length of ductwork.
Non-Solid Fuel Appliances (Rated 600°F)
Non-solid fuel appliances rated for 600°F will require downstream detection if the duct run contains any horizontal
section over 25 feet in length. Downstream detection should be installed at the end of a horizontal section. Duct
layouts that include less than 25 feet of horizontal ductwork will not require additional detection.
Solid Fuel Appliances (Rated 700°F)
Solid fuel appliances produce effluents that can accumulate inside the duct, especially in long horizontal duct runs.
Sparks from solid fuel appliances can travel into the ductwork and create fires that occur beyond the point where
the hood riser Firestat can detect them. Additional downstream Firestats ensure that these duct fires are detected
and the fire system actuates. Solid fuel applications require 600°F rated Firestats, and SOLO filters. Exhaust fan(s)
used with solid fuel appliances must use a steel wheel.
In addition to the 600°F rated Firestat, located in the hood riser, a second Firestat is required at the duct discharge
for solid fuel applications when the ductwork exceeds 10 feet in length or contains horizontal runs. Even if the
entire duct run is inaccessible, this additional Firestat is still needed. Mounting a Firestat in the fan may be an
option. On duct runs longer than 50 feet, a third Firestat will be required somewhere in the duct run, ideally at the
end of a horizontal run, if present. Duct runs longer than 100 feet will require additional Firestats, contact your
local sales office for more information.
NOTE: When additional Firestats are required, install in an accessible location near an access door, hood
riser, or fan. The door will provide access to install, clean, and replace the Firestat when needed. If a PCU
is equipped with electronic detection, PCU Firestats can serve as downstream detectors, if present. The
temperature rating of the Firestat in the duct must always match the temperature rating of the Firestat in
the riser.

Appliance Shutdown in Fault Conditions
The Fire Protection System is equipped to shut down the appliances if a fault condition is present. Table 17 shows
which fault condition affects the appliances’ fuel and power sources, alarm muting, and local trouble relay.
Local Alarm Muting
Depressing the fire system reset button can mute the local alarm. This will disable the sounder for 4 hours under
specific conditions. Table 17 shows which errors can be muted. It should be noted that the fault will not clear until
the fault condition is corrected.
Test Mode
Test Mode allows the hood to be tested with operational appliances without discharging the system on the
appliances. Once the appliances are started, test mode can be entered without the appliances shutting down for 15
minutes. However, once the fire system is activated, the shunt trip (electric appliances) and the gas valve will be
locked out until test mode is deactivated.
**During AC power failure, all gas appliances will be shut down. Electrical appliances will shut down on building
power loss.

DIP Switch Settings
When set from the factory (Figure 50), switches 1, 5, and 8 are in the Closed (On) positions. Switch 2, 3, 4, 6, 7 are
in the Open (Off) position. This should be considered the default positions and should not be changed.
Figure 50 - DIP Switch
• Each unit has a unique address based on the DIP switch 1-4 settings, 15 units max on a network.
• If address is 0 (all switches off), the unit will not accept or send any network traffic.
• The unit that has switch 5 set to on will be the “master” and will be in charge of polling all the units below it and
waiting for a reply. The lack of 3 replies in a row will cause an “interlock network supervision fault.” All units will
be polled in a burst every 3 seconds.
• For all non-master units, the lack of being polled for 10 seconds will cause an “interlock network supervision
fault.”
• Any unit detecting a fire condition will broadcast the notification once every second for as long as the condition
persists.
• When the Fire condition is cleared, 10 notifications will be sent, one every second.
• Any unit detecting a supervisory fault will broadcast the notification every 2 seconds until the condition is
cleared.
• When the supervisory fault condition is cleared, 10 notifications will be sent, one every 2 seconds.

POST-DISCHARGE MAINTENANCE
General Information
Liquid Fire Suppressant, the Aqueous Potassium Carbonate (APC) base wet chemical used in the TANK
Fire Suppression extinguishing system, is non-toxic. However, any food or cooking oils that have been
contaminated with wet chemical agent should be discarded. Refer to Safety Data Sheet (SDS).
After any system discharge, it is best to clean the area as soon as it is safe to do so. Prolonged exposure
of equipment to wet chemical can result in localized corrosion due to moisture in the air. Clean up should
be completed within 24 hours of any system discharge.
TANK Fire Suppression cylinders need to be replaced every 12 years, and after any system discharge.
Appliance Cleanup
No unusual cleanup procedure is required. The reaction of the wet agent and the grease is one of
saponification, and it produces a foam that can be wiped off. After the appliances have completely cooled,
the residue from the discharge may be cleaned up using a wet cloth or sponge. Ensure that all fuel and
electric power to the area has been shut down. Wear rubber gloves and eye protection while cleaning. If
skin or eyes come in contact with the agent, flush thoroughly with water.
Cleaning Distribution System
The TANK Fire Suppression extinguishing system must have all discharge piping and nozzles flushed out
with water after any discharge, as detailed in the following procedures.
Cleaning Nozzles
1. Remove all nozzles from the system.
2. Inspect each nozzle & filter and remove any debris.
3. Clean nozzle and strainer by flushing thoroughly with warm soapy water. Remove any foreign matter
that could impede flow.
4. Run water through the nozzle tip to ensure the orifice is not clogged.
5. Thoroughly dry nozzles with dry air or nitrogen and set aside.
WARNING!
Do not disturb the foam until the cooking appliances, plenum, and duct have cooled sufficiently.
Do not put water on hot grease as this will cause violent steaming and spattering.
WARNING!
APC wet agent is electrically conductive. To avoid electrical shock, de-energize all electric circuits
to appliances, outlets, and wiring by disconnecting or turning off the electric power at the main
fuse or circuit breaker box. Do not cleanup APC wet agent or touch electric appliances, outlets,
power cords, or other wiring with electric power on.

Cylinder Tank Maintenance
TANK Fire Suppression cylinders need to be replaced every 12 years, and after any system discharge.
WARNING!
Never assume that a cylinder is unpressurized. Handle all cylinders as if they are pressurized until
verified otherwise. Pressurized cylinders are extremely hazardous.
When performing any cylinder maintenance procedure, the cylinder must be properly secured to a
rigid structure capable of withstanding the full thrust that would result if the valve were to open
inadvertently.
Any time a cylinder assembly is unsecured, the anti-recoil plate must be installed on the valve
outlet to provide a safe, controlled discharge in the event of accidental actuation.
Failure to take proper precautions could result in death, serious personal injury and/or property
damage.
