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.
