The Slave Completer Kit includes a slavedischarge head and discharge control panel monitors the detection and3actuation devices and includes timers to delay thedischarge, allowing for safe departure from theprotected detection and alarm devices are the external4components that provide audible or visual signals toalert occupants of pending problems or the possibleneed to evacuate the protected space prior Dioxide systems can be designed for total floodingand local application protection.

3 The guidelines containedin the National Fire Protection Association Standard onCarbon Dioxide (NFPA 12) and OSHA standards, as well asstate and local requirements should be followed for eitherdesign. A total flooding system can be defined as injectingCO into a room, area or compartment that has the struc-2tural integrity to retain the agent once it has been dis-charged. The minimum concentration requirement fortotal flooding systems is 34% by volume. This minimumconcentration is suitable for a wide range of ordinarycombustibles and flammable liquids. Higher concentra-tions may be required for specific flammable liquids and/orhazards that may become deep seated. The local applica-tion method requires that CO be applied to the surface of2the protected hazard for a specified time period thatinsures the fire condition has been CYLINDER AND VALVE ASSEMBLYThe cylinders that are used to store CO are spun2steel containers manufactured to DOT Specifica-tion 3AA-1800 or 3 AAA-1800 or higher.

Each cylinder is stamp-ed with a serial number and hydrostatic testdate. They also come equipped with a steel capfor the physical protection of the cylinder valveduring shipment and handling.

The dischargehead is attached to the cylinder by means of a swivelnut that engages the threads of the valve. Threedifferent types of discharge heads can be used:a)pilot operated type with handwheel for manualoperation b)pilot operated type without handwheelc) Pressure operated typeEach of the three types includes an internal oper-ating piston connected to a hollow stem that is usedto upset the cylinder seat disc when operated,which allows the agent to exit. A stainless steel ballcheck at the top of the stem provides a safety fea-ture to prevent excessive loss of Carbon dioxidefrom the manifold if the system is discharged Pressure Carbon Dioxide 2001 Chemetron Fire Systems.
