REQUIRED FULL OPERATIONAL TRIP TEST
Victaulic recommends the full operational (trip) test every 3 years (at
minimum). NOTE: The frequency of the full operational (trip) test must
be increased in the presence of contaminated water supplies, corrosive/
scaling water supplies, and corrosive atmospheres. This test allows a
full flow of water into the sprinkler system; therefore, this test must be
performed when there is no chance for freezing conditions. In addition,
the authority having jurisdiction in the area may require full operational
(trip) tests on a more frequent basis. Verify these requirements by
contacting the authority having jurisdiction in the affected area.
1. Notify the authority having jurisdiction, remote station alarm
monitors, and those in the affected area that the full operational
(trip) test will be performed.
2. Record the water supply pressure and system air pressure.
3. Open the water supply main drain valve fully to flush the water
supply of any contaminants.
4. Close the water supply main drain valve.
5. Trip the valve by doing one of the following:
a. Open (energize) the solenoid valves
b. Open the manual pull station valve
6. Record the following:
6a. The time between opening the remote system test valve
(inspector’s test connection) and operation of the actuated
valve
6b. System air pressure when the valve operated
6c. The time between opening the remote system test valve
(inspector’s test connection) to when water flows from the
test connection’s outlet
6d. All information required by the authority having jurisdiction
7. Confirm that all alarms operate properly.
8. Continue to run water until it is clear.
9. Close the water supply main control valve.
10. Close the charge line ball valve.
11. Shut off the air supply.
12. Open the system main drain valve to drain the system.
13. After the system is drained, close the remote system test valve
