  • Page 22: Start-Up Procedure

    Commissioning and Startup 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 the nitrogen generation system. 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 23 4. Verify the nitrogen generation/air bypass valve is nitrogen generation position.* * The only time the nitrogen generation/air bypass valve should need to be in the “air bypass” position is for the NFPA 13 30-minute system fill time requirement. Turn the cabinet power switch ON (if not already On). The generator will prompt to complete the commissioning process through the HMI.

  • Page 24: Normal Operation

    Once in service, the nitrogen generator requires no additional intervention to function properly. Generator settings should not be altered without consulting ECS and the unit should not be powered down for any reason other than maintenance. To take the generator out of service for maintenance, follow these steps: 1.

  • Page 25: Sequence Of Operation

    Nitrogen Inerting Mode The application of supervisory nitrogen gas to a dry pipe or preaction fire sprinkler system using the ECS Dry Pipe Nitrogen Inerting (DPNI) protocol which is fundamentally different than the traditional application of compressed air as a supervisory gas.
  • Page 26 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 Air Maintenance Device (AMD), the AMD closes (no longer needing supervisory gas).
  • Page 27 If air compressor and nitrogen generator runtimes are greater than four (4) hours, contact ECS immediately. Restart of the Nitrogen Inerting Process Whenever the fire sprinkler system(s) are serviced and refilled with air, the ECS DPNI protocol using the “fill and purge breathing” process must be reinitialized. •...
  • Page 28 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. • 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.

  • Page 29: Auxiliary Equipment

    Support Hanger Not Required General Description The ECS Standard Vent (PAV-D/DQ) provides oxygen venting in dry pipe and preaction fire sprinkler systems. As a fire sprinkler system is filled with a continuous supply of nitrogen gas from the Nitrogen Generator System, the PAV-D/DQ allows oxygen rich gas to be vented from the fire sprinkler system. Over a short period of time the Vent will almost completely remove oxygen from the fire sprinkler system (less than 2% oxygen).
  • Page 30 NOTE: If the vent assembly is not equipped with a restricted venting orifice, one will be provided by ECS during system commissioning. The restricted venting orifice must be installed before proceeding with the steps below. 2. Determine the low air alarm pressure and the turn-on pressure of the nitrogen generator.

  • Page 36 B - Black Steel 40 - Schedule 40 The ECS In-Line Corrosion Detector is designed to provide an early warning indication of internal corrosion activity in water-based fire sprinkler systems. The device is designed to be installed where corrosion is most likely to occur: the air/water interface.
  • Page 37 Step 1: Contact an ECS Engineer to determine a location within the sprinkler system where corrosion is likely to occur. In wet pipe systems locate on a high point at the air/water interface; in dry pipe and preaction systems locate on a horizontal portion of the mains in an area with trapped water.
  • Page 38 (203mm (W) X 254mm (H) X 152mm (D)) General Description The ECS SMART Gas Analyzer (SGA-1) provides a continuous real-time monitoring of nitrogen/oxygen concentration levels within a dry pipe and preaction fire sprinkler system. The analyzer samples discharge gas from an adjacent Standard Vent (PAV-D/DQ) or SMART Vent (PSV-D/DE). The gas flows out of a restricted orifice on the vent through pressure-rated tubing to provide slow, controlled flow to the analyzer.
  • Page 39 Installation Instructions 1. Mount the SMART Gas Analyzer on a wall adjacent to the PAV-D/DQ Vent or the PSV-D/DE SMART Vent (not included). 2. Once mounted, connect the 5/32” tubing to the push-connect fitting on the top of the SGA-1. 3.
