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 valve 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).
NOTE: The agent itself may be stored down to -20°F (not operational system temperature).

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

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 15.
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 actu-
ators. A vent limiting orifice is present to allow easier resetting of SVA pistons during inspections.
The PAK consists of a pneumatic actuator, 24V DC solenoid valve, solenoid strainer (recommended by the
manufacturer), check valve, primary actuator hose, and associated fittings.
When activated, through automatic or manual system actuation, the control panel sends a momentary 24V
DC release signal. The solenoid strainer will filter out debris from entering the system. The PAK solenoid
will open, allowing pressure from the primary cylinder to pass through the solenoid and check valve. The
pressure flows into the primary actuator (actuating the primary cylinder), and into the interconnected sec-
ondary 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 line vent limiting orifice
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. When
testing/inspecting, if a component fails inspection, replace the PAK assembly.
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. Apply Leak Lock joint sealing compound on the sealing surface of the
Schrader valve when connecting/replacing the supervisory pressure switch.

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.

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. Each
duct and plenum nozzle protection is 4 flow points.
Plenum Protection
The nozzle(s) (page 8), 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.
Figure 17 - Single Bank Filter Plenum

Figure 18 - Dual V-Bank Filter Plenum
Duct Protection
The nozzle(s) (page 8) is used for the protection of exhaust ductwork and can protect any duct cross-
section type (e.g. round, square, or rectangular). A sufficient quantity of nozzles must be provided to
ensure that no single nozzle coverage exceeds 75" in perimeter.
A single nozzle will protect a duct up to 75” perimeter (22” nominal diameter) and unlimited length. Two
nozzles are required for protection of 75-150” perimeter and unlimited length. A minimum of 3 nozzles is
required for protection of ducts exceeding 150" perimeter (36” nominal diameter) and unlimited length.
When using multiple nozzles (modular protection), the coverage area for each nozzle must not exceed 75"
perimeter.

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 8.
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 20. 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.
Figure 22 - Overlapping Protection Option
20
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” max spacing. Max oil capacity: 24.75 gallons. Refer to Table 4 on page 21.
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” max 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” max nozzle spacing per tank.
• Woks larger than 24 inch diameter, 4 nozzles at 30” max spacing per tank.
• Appliance with shelves, 4 nozzles at 36” max spacing per tank.
• Solid Fuel Appliances, 3 nozzles at 24” max spacing per tank.
Refer to “Coverage Exceptions” on page 21 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 may be ended, and a new zone started for the new group of appliances.
Examples where continuous protection may be 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).

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 21 for more details on coverage exceptions.
Figure 23 - 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

Fire Protection Manual Actuation Device
Figure 38 - Activation Device
The push/pull station (Figure 38) 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. Refer to Table 9 for device part numbers
and replacement parts.
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.
