Tank Mounting Bracket (Secured to cabinet with rivets) 4. Cylinder Tanks (Up to four tanks may be installed depending on cabinet size.)

  • Page 6: Cylinder Assembly

    Cylinder Assembly The EWC 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 optional supervisory pressure switch (for secondary cylinders).

  • Page 7: Cylinder And Actuator Bracket

    Figure 4 - Cylinder and Actuator Bracket Discharge Adapter The discharge adapter (p/n WK-283952-000) is used to connect the EWC 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: Primary Actuator Kit (Pak)

    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.

  • 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: Nozzles

    Nozzles There are various types of nozzles utilized in the EWC extinguishing system. The TF1 nozzle (p/n 87- 300021-001) is a 2 flow nozzle and is used for all zone protection. The ADP nozzle (p/n 87-300020-001) is a 1 flow nozzle and is used for plenum, duct, and dedicated appliance coverage (e.g., salamanders, upright broilers, chain broilers, and range with shelf).

  • Page 11: 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 EWC 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. They are available in 120V AC and 24V DC, ranging from 3/4”...

  • Page 12: Installation

    In a fire condition or upon manual actuation, the EWC 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 EWC liquid fire suppressant to the protected hazard areas.

  • Page 13: Vent Plug

    Vent Plug The vent plug is factory-installed in the agent distribution supply line. The vent plug can be installed in the outlet or run off a tee in the distribution pipe network. The vent plug must be installed from a horizontal to vertically up position to ensure that it will open upon slight rises in pipe system pressure (e.g., due to ambient temperature fluctuation).

  • Page 14: Primary Actuator Kit (Pak)

    Primary Actuator Kit (PAK) Figure 16 - Actuator Valve Set Position The primary actuator kit is mounted to the primary cylinder bracket during shipment and when testing the system. With the cylinders securely mounted and connected to the system piping, the primary actuator kit can be installed onto the primary cylinder for the final setup.

  • Page 15: 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 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.

  • Page 16: Duct And Plenum Protection

    Duct and Plenum Protection The EWC extinguishing system for duct and plenum coverage can be provided by independent EWC tanks and piping or integrated with the EWC tanks and piping used for protection of the appliances.

Duct obstructions and common ductwork must be protected in accordance with this manual, NFPA 17A and NFPA 96.

  • Page 20: Ventilation Exhaust And Dampers

    Ventilation Exhaust and Dampers The EWC 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 21: Appliance Protection

    Appliance Protection The EWC system utilizes both overlapping and dedicated nozzle appliance coverage, depending on the type of cooking appliance(s) requiring protection. Overlapping appliance coverage allows a given area under the hood, defined as the hazard zone, to be protected by overlapping (TF1) nozzles. Nozzles are evenly spaced at the same height and alignment (front-to-back) relative to the hazard zone.
  • Page 22 8. When the depth of the appliance exceeds maximum cooking hazard dimensions, a second row of nozzle coverage should be added. Figure 23 illustrates the placement of nozzles for EWC overlapping protection.

  • Page 23: Group Protection

    Group Protection Overlapping protection provides coverage for a continuous hazard zone, with all TF1 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.
  • Page 24 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. Overlapping nozzles must be spaced no further than the maximum allowed interval 24” on center. Figure 24 - Example 1 Overlapping Hazard Zone 12”...
