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. -
Page 5: Components
COMPONENTS The following section lists the major components used in the TANK Fire Suppression extinguishing system. Figure 1 - Shipping/Test View 1. Unit is shown in Shipping/Test Position 2. Tank Straps 3. Tank Mounting Bracket (Secured to cabinet with rivets) 4. -
Page 6: Cylinder Tank Assembly
(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. -
Page 7: Cylinder Tank And Actuator Bracket
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. -
Page 8: Nozzles
Nozzles The Overlapping Female Nozzle(s) (p/n OL-F) are used for plenum, duct, overlapping appliance protection, 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. -
Page 9: Secondary Valve Actuator (Sva) And Hose
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. -
Page 10: 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. -
Page 11: Installation
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. -
Page 12: Removing Full Cylinder Tanks (Optional)
(Figure 14). If the system contains multiple tanks, check all additional actuators. 2. Use a 1/2" and 9/16" box end wrench to remove the two mounting bolts holding the tank on the bracket. 3. Loosen the straps. 4. Remove the tanks. Repeat for additional tanks. -
Page 13: Primary Actuator Kit (Pak)
Connecting this hose earlier may result in accidental system discharge. Refer to “START-UP/ INSPECTION TEST PROCEDURE” on page 59 for the testing and commissioning procedure. When inspecting the primary actuator hose, replace O-ring. Refer to “TANK FIRE SUPPRESSION SYSTEM PARTS” on page 77. -
Page 14: Supervisory Pressure Switch
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 cylin- ders, 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. -

Page 18: Ventilation Exhaust And Dampers
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. -
Page 19: Appliance Protection
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. -

Page 45: Fire Protection System Supervised Loops
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 ded- icated to all sensors, while the other is dedicated to all manual actuation devices (push/pull stations). -
Page 46: Supervised Loop Electrical Details
Supervised Loop Electrical Details NOTE: Place the panel in test mode when checking the supervised loop circuit. Before checking the supervised loop circuit (Figure 44), verify all CORE power supplies (PS-02) are set to 27.5V DC. Check all supervised loop connections. Verify wiring is properly connected and secure. If any of the readings in Table 14 are out of range or other faults are present, there is an issue with that loop or associated components/ wiring. -
Page 47: Pcu Fire System
Installation, commissioning, or resetting of the fire system must be done by a licensed fire system installer. Use the guidelines set forth by the appropriate fire system manual; PCU with CORE Fire Suppression System manual, Model TANK (Electric Wet Chemical) Extinguishing System, or other fire system manufacturer. -
Page 48: Pcu Fire System Nozzles
Table 15 provides details on PCU size, modules, and nozzle quantity per unit. Pollution Control Units (PCU) cov- ered by a TANK Fire System can utilize up to 12 nozzles per tank. PCU Fire System type “REFS” is covered by TANK. -
Page 49: Operation
The electric release solenoid is energized, allowing pressurization of the pneumatic actu- ator(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. -
Page 50: Test Mode Overview
Test Mode Overview The fire protection system has an integrated option for testing. When in test mode, the release solenoid is disabled and will prevent the fire extinguishing agent from spraying on the appliances. For testing purposes, this will allow the activation of the fire system, audible alarm, shunt trip breaker (if applicable), and shut down of appliances via gas valve reset relay. -
Page 51: Battery Backup
Battery Backup 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. Figure 48 - Battery Backup The fire protection system contains a battery backup. -
