If a decrease in pressure is noted, repeat the FDT leakage check using a leak indicator solution.
All of the following accessories will connect to an End of Line (EOL) Adapter. The EOL Adapter can be installed by following the appropriate procedures
in Section 5.4.1 or Section 5.4.2.

5.5 System Activation
1. Install the detection tubing, fittings, and accessories according the procedures specified in Section 5.3 and Section 5.4.
2. With the system ball valve still closed, connect the detection tubing to the system using the appropriate procedure in Section 5.4.1 or Section
5.4.2.
3. Attach the filling adapter (P/N 600023 or 600028) to the End of Line Adapter. Refer to Section 5.4.3.
4. Using a regulated dry nitrogen supply, pressurize the detection tubing through the filling adapter to 195 psig (10.3 bar). It is recommended
to have a portable dry nitrogen cylinder or Firetrace Nitrogen Fill Kit for on-site use.
5. Remove the filling adapter and thread the pressure gauge & 0-ring (Firetrace P/N 400027) into its place to verify that the tubing is pressurized
to at least 195 psig at 70°F (10.3 bar at 21°C) (pressure may have to be adjusted for temperatures higher or lower than 70°F). Refer to
Section 5.4.3 for further instructions.
6. With the gauge still attached to the filling adapter, test for leakage:
