Figure 5 - Trim Components
E. Hydrostatic Test:
The Preaction System, including S�rinkler Pi�ing and S�rinklers shall be hydrostatically tested at 200 PSI (13.8 bar) and maintained
�or two hours, in accordance with NFPA 13. Systems normally subjected to working system �ressures in excess o� 150 PSI (10.3 bar)
shall be tested at a �ressure o� 50 PSI (3.4 bar) in excess o� system working �ressure.
F. Placing the Valve in service:
(Re�er to Figure 5.)
When the �reaction system is ready to be �laced in service, veri�y that the electric release system has been reset and is in a normal
condition.
1. �eri�y that the water su��ly main control valve (not shown) su��lying the G-4000P �alve is closed.
2. Close the �rime valve.
3. O�en the main drain valve.
4. O�en the �low test valve.
5. Drain all water �rom the �reaction system. I� the system has o�erated, or i� water has entered the system, allow enough time
to com�letely drain the system.
6. Close the main drain valve.
7. O�en the �riming valve. Prime water �ressure will enter and ex�and the valve’s internal dia�hragm assembly onto the valve
seat, e��ectively closing the valve. �eri�y �rime �ressure has been established on the �rime �ressure gauge.
8. Establish air �ressure on the system.
9. When the �riming �ressure has been veri�ied as being established, slowly o�en the water su��ly control valve (not shown).
10. When �low is develo�ed �rom the �low test valve, CLOSE the �low test valve.
11. Fully o�en the water su��ly main control valve.
12. �eri�y that no water �lows �rom the dri� check when the �lunger is �ushed.
13. Secure all valves in their normal o�erating �osition.
14. Reset the release control �anel to clear any su�ervisory alarms.
15. Noti�y Authorities Having Jurisdiction and those in the a��ected area that the system is in service.
16. The system is now �ully o�erational.
G. operational Test:
An o�erational test shall be �er�ormed on the system in accordance with NFPA 13. Re�er to Section 6 �or Ins�ection and O�eration
Test Procedures.
