NOTE: Ensure an appropriately rated disconnect switch and circuit breaker (minimum 15 Amps and a SCCR of 5 kVA) are installed in a suitable and accessible location in accordance with the Applicable national and/or local codes (i.e. NFPA 70).
Step 4: 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. Please consult the manual provided with each compressor for more details.
NOTE:
Confirm the available power source is compatible with the wiring configuration of the air compressor. Contact Johnson Controls if there is a discrepancy. Visit the CONTACT US page at www.tyco-fire.com for the contact information by location.
The auto-drain power supply can be connected to the nitrogen generator power supply.
460v/3 phase or 208v/3 phase Landing Points
Labeled L1, L2, L3
NOTE: Step 5:
Ensure an appropriately rated disconnect switch and circuit breaker (minimum 15 Amps and a SCCR of 5 kVA) are installed in a suitable and accessible location in accordance with the Applicable national and/or local codes (i.e. NFPA 70).
Plumb the Air Supply Line to Nitrogen Generator
Figure 2 – AMERICAS Power Supply Connections
Connect the air discharge plumbing from the air compressor to the air inlet of the nitrogen generator using a minimum 1⁄2” black steel, galvanized steel, or copper lines. The air compressor start-up kit includes a flex-hose connection to be installed between the air compressor and nitrogen generator to reduce vibration.
Step 6a: Plumb the Nitrogen/Air Supply Line – No Additional Air Compressor (Figure 3a)
The nitrogen/air discharge plumbing from the TYCO Nitrogen Generator must be connected directly to the dry pipe or preaction valve trim using a minimum 1⁄2” black steel, galvanized steel, or copper lines. The size of the nitrogen/air supply line must be based on both the length of pipe between the nitrogen generator and fire sprinkler systems and the total volume of fire sprinkler systems being supplied.
