FULL OPERATIONAL (TRIP) TEST
WARNING
The building owner or their representative is responsible for
maintaining the fire protection system in proper operating
condition.
To ensure proper system operation, valves must be inspected
in accordance with current national standards or in accordance
with the requirements of the local authority having jurisdiction
(whichever is more stringent). Always refer to the instructions
in this manual for additional inspection and testing require-
ments.
The frequency of inspections must be increased in the
presence of contaminated water supplies, corrosive/scaling
water supplies, and corrosive atmospheres.
Depressurize and drain the piping system before attempting to
install, remove, adjust, or maintain any Victaulic products.
Failure to follow these instructions could cause system failure,
resulting in death, serious personal injury, and property damage.

Victaulic recommends the full operational (trip) test every 3 years (at
minimum). NO
TE: 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 per-
formed 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) tests will be performed.
2. Record the system air pressure (7) and water supply pressure (5).
3. Open the remote system test valve (inspector's test connection) to
simulate the operation of a sprinkler.
4.
Record the following:
4a Time between opening the remote system test valve (inspec-
tor's test connection) to the operation of the dry valve
4b. System air pressure (7) when the valve operated.
4c. Time from opening the remote system test valve (inspector's
test connection) to when water flows from the test connec-
tions' outlet
4d. All information required by the authority having jurisdiction
5. Confirm that all alarms operate properly.
6. Continue to run water until it is clear.
