TRIP TESTS
Partial Trip Test
Partial trip tests are required to confirm proper valve operation;
however, this test does not confirm full system operation. Victau-
lic recommends that the partial trip test be performed annually.
NOTE:
The authority having jurisdiction in your area may require
the partial trip test on a more frequent basis. Verify these require-
ments 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 partial
flow test will be performed.
2.
Record the water supply pressure (5) and system air
pressure (7).
3.
Partially close the water supply’s main control valve (2).
4.
Open the inspector’s test connection to simulate an open
sprinkler. This can also be done by opening the system main-
drain valve (4), as shown above.
5.
Record the system air pressure when the valve actuates.
6.
Close the water supply’s main control valve (2).
7.
Close the system main-drain valve (4).
8.
SHUT OFF THE AIR SUPPLY.
9.
Close the piston charge line ball valve (8).
10.
Perform all steps in the “Placing the System in Service”
section, starting on page 11.
Full Trip Test
Victaulic recommends full trip testing every 3 years. This test
allows a full flow of water into the sprinkler system; therefore, this
test must be performed in warm weather when there is no
chance of freezing conditions.
NOTE:
The authority having juris-
diction in your area may require this full trip test on a more fre-
quent 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 (5) and system air pres-
sure (7).
3.
Open the remote system test valve (inspector’s test con-
nection) to simulate the operation of a sprinkler.
4.
Record the following:
4a.
Time between opening the remote system test valve (in-
spector’s test connection) to the operation of the dry valve
4b.
System air pressure with the valve operated
4c.
Time from opening the remote system test valve (inspec-
tor’s test connection) to when water flows from the test connec-
tion’s outlet
4d.
