    VIKING SYSTEM SPECIFICATIONS

     ?HP DRY PIPE SYSTEM

    The fire sprinkler systems installed in areas with temperatures that cannot be reliably maintained above 40?F and the system supply pressure is above 175 PSI shall be a HP dry pipe system. System shall be installed in conformance with the current Edition of N.F.P.A. 13, Standard for Installation of Sprinkler Systems. All materials installed shall adhere to the manufacturer’s installation guidelines.

SYSTEM DEVICES

Deluge Valve

    HP dry systems shall utilize a 90? pattern type deluge valve. The deluge valve shall be externally resettable by hydraulic means. The deluge valve shall employ a prime shut off valve, which shall provide a positive shutoff to the prime water supply. Inlet and outlet connections of the deluge valve can be flanged by flanged or flanged by grooved, respectfully. The deluge valve shall be UL Listed and Factory Mutual Approved with a ductile iron body. Deluge valve shall have a working pressure up to 250 PSI. Valve trim shall be galvanized, compatible and shall be installed following the manufacturer’s specifications. The Deluge Valve manufacturer to be The Viking Corporation. Deluge Valve to be Viking Model E-1.

System Control Valve

    The dry system control valve shall be a listed indicating type valve. The control valve shall be UL Listed and Factory Mutual Approved for fire protection installations. The system control valve shall be rated for normal working pressure but in no case less than 175 PSI.

Dry Pendent Sprinklers

    (Insert applicable product specification.)

Brass Upright Sprinklers

    (Insert applicable product specification.)

Drains

    Where the capacity of trapped sections of piping is less than 5 gallons, an auxiliary drain consisting of not less than a ?" valve and plug shall be provided. Where the capacity of trapped sections of piping is more than 5 gallons, a drain consisting of two 1" valves and a 2" by 12" condensate nipple (drum drip) shall be provided.

Compressed Air Supply

    The air supply compressor should be sized to establish total required air pressure in 30 minutes. The air supply must be regulated, restricted and maintained automatically. The air supply must be regulated to maintain the pressure desired in the system piping. The air pressure settings shall be in accordance with the manufacturer’s

    instructions. The air supply must be restricted to ensure that the automatic air supply cannot replace air as fast as it escapes when a sprinkler on the system operates.

Float Check Valve

    The system shall have a float check valve installed between the anti-flood device and the system riser. The float check valve shall allow air to pass from the system riser to the anti-flood device to set the system. When the system discharges the float check valve closes when water flows to the inlet side of the device, protecting the anti-flood device from water pressure on its inlet and protecting the deluge valve from resetting. Float Check Valve manufacturer to be The Viking Corporation. Float Check to be Viking Model A-1.

Air Compressor

    (Insert applicable product specification.)

Air Maintenance Device

    Air supplies provided for sprinkler systems shall be equipped with an automatic air pressure maintenance device. The air maintenance device shall be equipped with a ?" air supply bypass with a field adjustable air pressure regulator with a built-in ball check valve to eliminate air loss when system is in service. The air maintenance device shall have a factory setting of 40 PSI. The Air Maintenance Device manufacturer to be The Viking Corporation. Air Maintenance Device to be Viking Model D-2.
