Certifications and Approvals
The Tank Fire Suppression system is ETL Listed in accordance with ANSI/CAN/UL/ULC 300, ULCORD-
C1254.6.
The microprocessor-based control board is ETL Listed to UL Standard 864 and CAN/ULC-S527-11.
The Tank Fire Suppression system is acceptable for use in New York City, and is approved per FDNY
COA #5870.
System Overview
The Tank Fire Suppression extinguishing system provides fire protection for commercial cooking
appliances and ventilation. The Tank Fire Suppression extinguishing system is electrically released via a
24V DC solenoid valve. Extinguishing system units with electrical detection, activation, and control require
the use of a Listed Control Panel, which has been found acceptable for releasing device service and which
is compatible with the electrical actuators used on the extinguishing system. In addition, all electrical
detectors, notification devices, and pull stations are required to be Listed and compatible with the Control
Panel.

Cylinder 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 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 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 nozzle (p/n 3070-3/8H-SS10) is a 4 flow nozzle and is 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
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.

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.
