  • Page 4 Cautions and Warnings CAUTION: Do not install the Nitrogen Generator or Air Compressor Package in an area where ammonia, sulfur dioxide, hydrogen sulfide, mercaptans, chlorides, chlorine, oxides of nitrogen, acid fumes, solvent vent vapors, and ozone vapors or similar contaminates exist. The equipment can be damaged by ammonia and other vapors shortening membrane life.

  • Page 5: System And Product Information

    SYSTEM and PRODUCT INFORMATION Dry Pipe Nitrogen Inerting (DPNI) Dry Pipe Nitrogen Inerting technology was developed by Engineered Corrosion Solutions, LLC, (ECS) and is used to control oxygen corrosion in dry pipe and/or preaction fire sprinkler systems. DPNI is executed by employing a “fill and purge”...
  • Page 6 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 3-5 psig (.2-.3 bar) pressure range to facilitate removal of oxygen gas from the system.
  • Page 7 Recommended Monitoring Equipment In-Line Corrosion Detectors The In-Line Corrosion Detector (ILD) is designed to provide an early warning of corrosion activity within the fire sprinkler system. The ILD features a double wall construction that incorporates a thin milled section of pipe (.035” (8.9mm)) surrounded by a full-thickness piece of pipe to detect and alert to the presence of corrosion activity.
  • Page 8 AdvancedIQ Vent Controller (AVC) The AdvancedIQ Vent Controller (AVC) provides 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, allow oxygen-rich gas to be vented from the fire sprinkler system.

  • Page 13: Operational Information

    OPERATIONAL INFORMATION System Operating Pressures When multiple dry pipe and preaction fire sprinkler systems are connected to one nitrogen generator, the fire sprinkler systems must operate at the same supervisory gas pressure. In applications where multiple dry pipe and preaction fire sprinkler systems are connected to one (1) nitrogen generator and there is more than one (1) supervisory gas pressure an ECS Nitrogen Interface Controller (NIC-1) must be included in the project.
  • Page 14 To ensure proper operation of the sprinkler system and the nitrogen generator, calibrate the sprinkler system operating pressure to the turn-on and turn-off pressure of the nitrogen generator using the Air Maintenance Device Pressure Adjustment Procedure (section 6.f.) in the Maintenance Section of this manual.

  • Page 16: Start Up And Operational Procedures

    Start Up and Operational Procedures INSTALLATION Installation Instructions Installation of the ECS AdvancedIQ Nitrogen Generator and air compressor requires ten (10) steps: 1. Mount the nitrogen generator cabinet in the appropriate location. 2. Mount the air compressor in the appropriate location. 3.
  • Page 17 The cabinet includes pre-punched holes in the feet for floor mounting and holes in the back panel for wall support using standard anchors. NOTES: 1. The AG-6500/11000 cabinet does not include holes in the back panel for wall support. 2. The AG-18500/22500 cabinet includes holes in the back panel for wall support. 3.
  • Page 18 Step 4: Connect the Air Compressor Power Supply The air compressor requires a dedicated power supply to prevent interaction with other equipment. Provide a means of power disconnect adjacent to the air compressor in accordance with manufacturer’s published instructions and in accordance with the applicable national and/or local codes (i.e., NFPA 70). The incoming power supply line is connected to the terminal block inside the NEMA 4 power supply box on the air compressor.

  • Page 23: Commissioning And Start Up Procedure

    COMMISSIONING and START UP PROCEDURE Only qualified personnel should commission the new equipment into service once it is installed. Once the nitrogen generator has been configured, there should be no reason to adjust them. Pre-Commissioning Information Prior to setting the cut-in (turn-on) and cut-out (turn-off) pressures of the nitrogen generator, identify the following sprinkler system pressures: 1.
  • Page 24 NOTE: The only time the nitrogen generator should need to be in the “air bypass” position is for the NFPA 13 30-minute system fill time requirement. 7. Turn the cabinet power switch ON (if not already on). The generator will prompt to complete the commissioning process through the HMI.

  • Page 25: Normal Operation

    3. AdvancedIQ Vents Press the Vent System button on the AdvancedIQ Vent Controller which initiates the fourteen (14) day nitrogen inerting process. At the completion of the fourteen (14) day nitrogen inerting process or when the nitrogen purity has obtained 98%, the AdvancedIQ Vent Controller will automatically cease the nitrogen inerting process.

  • Page 26: Sequence Of Operation

    Sequence of Operation Once in service, the nitrogen generator requires no additional intervention to function properly. Nitrogen generator settings should not be altered without consulting ECS and the unit should not be powered down or bypassed for any reason other than a service or maintenance procedure as detailed in the Maintenance Section.
  • Page 27 ECS Nitrogen Generator Pressure Cycling for Dry Pipe and Preaction Fire Sprinkler Systems OPERATING NOTES: The nitrogen generator produces nitrogen increasing the pressure in the nitrogen supply line which increases the pressure in the fire sprinkler system. When the pressure in the fire sprinkler system reaches the pressure setting of the AMD, the AMD closes (no longer needing supervisory gas).
  • Page 28 Supervisory Gas Mode Once the DPNI “fill and purge breathing” protocol is complete the nitrogen generator will automatically operate in the Supervisory Gas Mode. Whenever a fire sprinkler system needs supervisory gas the nitrogen generator and compressor will automatically operate. 1.
  • Page 29 System Power Loss In the event of a system power loss, all programmed information in the nitrogen generator is stored in the nitrogen generator and the nitrogen generator will automatically restart once system power is restored. 1. Where Standard Vents are installed, the system will automatically return to Nitrogen Inerting Mode or Supervisory Gas Mode, depending on which mode the nitrogen generator was in when the power loss occurred.
