Full Trip Test
Victaulic recommends full trip testing every three years.
This test allows a full flow of water into the sprinkler sys-
tem; therefore, this test must be performed in warm
weather when there is no chance of freezing conditions.
NOTE:
The authority having jurisdiction in your area
may require that you perform this full trip test 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
trip test will be performed.
2.
Record the water supply pressure and system air pres-
sure.
