1.8.3 Semi-annually
1. Main water supply valve (D1) switch shall be operated
to verify the switch actuation upon movement of the
hand wheel.
2. Check alarm pressure switch (C1) and optional water
motor gong (C2) by opening the alarm test valve (B5) .
3. Perform functional test of all components of the system.
1.8.4 Annually
1. Perform full flow trip test (see paragraph 1.7.3 of the
current section).
2. Record indicating the date of the last trip, tripping time
and name of the organization conducting the test shall
be maintained at a location available for review by the
AUTHORITY HAVING JURISDICTION
.
3. Perform main drain test (see paragraph 1.7.4 of the
current section).
1.8.5 Every 5 years
1. Test on gauge (gauge precision required: less than 3%
of the full scale).
2. Perform test on control valve operation.
3. Deluge valve (A1) and their associated strainers, filters
and restriction orifices shall be inspected internally.
4. Perform main drain test (see paragraph 1.7.4 of the
current section).
