e. Once the sprinkler system(s) obtain the desired pressure:
i. Turn the nitrogen generation/air bypass valve to the “nitrogen generation”
position.
NOTE: Bypass Alarm indicator will turn off.
If an AMD is not installed, filling process is complete.
ii. Close the AMD fast fill valve and open the AMD regulated valve.
iii. Open AMD regulated valves that were previously closed on any systems not being
filled.
f. Initiate the fourteen (14) day nitrogen inerting process (See Nitrogen Inerting Process).
g. Once the nitrogen inerting process is completed, the TYCO nitrogen generator will
continue to automatically operate when any of the associated sprinkler systems require nitrogen.
2. Filling
a. Close the nitrogen supply line ball valve from the nitrogen generator.
b. Open the air supply ball valve from the separate air compressor.
NOTE: If AMD is not installed, proceed to step e.
c. Open the fast fill valve and close the regulated valve of all appropriate air maintenance devices (AMDs) necessary to fill the sprinkler system(s).
d. Close the fast fill and regulated AMD valves on any system not being filled.
e. Once the sprinkler system(s) obtain the desired pressure:
i. Close the air supply ball valve from the separate air compressor.
ii. Open the nitrogen supply line ball valve from the nitrogen generator.
NOTE: If an AMD is not installed, filling process is complete.
iii. Close the AMD’s fast fill valve and open the AMD’s regulated valve.
iv. Open regulated valve on AMDs on any system not being filled that were
previously closed.
f. Initiate the fourteen (14) day nitrogen inerting process (See Nitrogen Inerting Process).
g. Once the nitrogen inerting process is completed, the TYCO nitrogen generator will
continue to automatically operate when any of the associated sprinkler systems require nitrogen.
Nitrogen Inerting Process
1. TAV-D Vents
a. Open the ball valve on the TYCO TAV-D Vent to initiate the fourteen (14) day nitrogen
inerting process.
b. Close the ball valve on the TYCO TAV-D Vent at the completion of the fourteen (14) day
nitrogen inerting process.
2. TSV-D SMART Vents
a. Depress the “Vent” pushbutton on the TYCO SMART Vent Controller which energizes the solenoid on the SMART Vent to initiate the fourteen (14) day nitrogen inerting process.
