    SYSTEM AND PRODUCT INFORMATION Dry Pipe Nitrogen Inerting (DPNI) Dry Pipe Nitrogen Inerting technology is used to control oxygen corrosion in dry pipe and/or preaction fire sprinkler systems. DPNI is executed by employing a fill and purge differential pressure cycle (breathing) within the sprinkler pipe network.

  • Page 8: Tyco Vent Controller

    Tyco Vent Controller The Models TVC-2 and TVC-6 Tyco Vent Controller (TVC), herein called the TVC or vent controller, provide automatic oxygen venting, monitoring of nitrogen/oxygen concentration levels, and monitoring of the sprinkler system pressure within each dry pipe/preaction fire sprinkler system. As a fire sprinkler system is filled with a continuous supply of nitrogen gas from the nitrogen generator system, the vent, installed on the sprinkler system riser, allows oxygen rich gas to be vented from the fire sprinkler system.

  • Page 10: Oxygen Removal Vent

    Oxygen Removal Vent To completely remove the oxygen in a dry pipe and preaction fire sprinkler system, it is necessary to install a vent on the main riser of each fire sprinkler system. Vents allow for a system to breathe, which requires a 3 psi to 5 psi (0.2 bar to 0.3 bar) pressure range to facilitate removal of oxygen gas from the system.

  • Page 43: Maintenance

    MAINTENANCE Safety Warning Only qualified personnel can perform inspection, testing and maintenance of the nitrogen generation equipment. Prior to any system maintenance on the nitrogen generation system, ensure that the nitrogen generator is isolated from the compressed air supply and all system risers. Ensure that the nitrogen generation system and the associated piping that is to be manipulated is completely depressurized prior to performing any maintenance.

  • Page 44: Oxygen Removal Vent Maintenance

    Oxygen Removal Vent Maintenance 1. The vents must be inspected annually at minimum. While isolation ball valve is in the open position, check for air/water leaks and ensure the pressure gauge is displaying normal system pressure. 2. While isolation ball valve is in the closed position, inspect the condition of the in-line filter to protect against blockage of the restricted venting orifice.
