OWNER'S OPERATION & MAINTENANCE MANUAL
FM-0860-0-31F
4.8 INSPECTIONS & TESTS
NOTICE: THE OWNER IS RESPONSIBLE FOR
MAINTAINING THE FIRE PROTECTION SYSTEM AND
DEVICES IN PROPER OPERATING CONDITION.
The purpose of the periodic inspection and tests is to insure
that the system is operating satisfactory and to identify
problems that could adversely affect the performance of the
system. Inspection and tests of the system shall be
accomplished in accordance with NFPA-25, NFPA-72 and
NFPA-2001. At least annually, the system shall be thoroughly
inspected and tested for proper operation by competent
personnel. In addition, the Authority Having Jurisdiction may
have additional maintenance, testing, and inspection
requirements that must be followed.
WARNING ! Any system maintenance that involves
placing the system out of service may eliminate the fire
protection capabilities of that system. Prior to proceeding,
notify all Authorities Having Jurisdiction.
Records
Records of inspections, tests, and maintenance of the system
and its components shall be made available to the Authority
Having Jurisdiction upon request. Typical records include, but
are not limited to, detection system, NOVEC 1230 cylinder
inspections, valve inspections, trip tests of preaction valve.
Acceptance test records should be retained for the life of the
system. Subsequent test records should be retained for a
period of 1 year after the next test. The comparison
determines deterioration of system performance or condition
and the need for further testing or maintenance.
4.8.1 Preaction low air pressure supervisory test
To test preaction system “low air” supervisory:
Note: To prevent operation of the deluge valve (A1) and
filling of the sprinkler piping with water during the test,
CLOSE main water supply control valve (D1) and OPEN
drain test drain (B6).
1. Slowly open the Inspectors test valve or the main drain
valve (D3).
2. Verify that low air supervisory operate within pressure
setting from table 5.3.
3. Close the Inspectors test valve or the main drain
valve (D3).
4. Establish recommended air pressure.
5. Reset the remote releasing control panel.
When testing is complete, return the system to
service:
1. Verify that the pressure indicated on pressure
gauge (B11) indicates that the priming chamber is
pressurized with system water supply pressure
indicated on pressure gauge (B12).
2. OPEN drain test valve (B6).
3. PARTIALLY OPEN main water supply control
valve (D1).
4. When full flow develops from flow test valve, CLOSE
the drain test valve (B6).
5. FULLY OPEN and secure the main water supply
control valve (D1).
6. Verify that the alarm test valve (B5) is CLOSED and
that all other valves are in their "normal" operating
position (see figure 4.5).
7. Verify that there is no flow from the drip check
valve (B7) when the plunger is pushed.
4.8.2 Preaction full flow trip test
Performance of a trip test is recommended annually during
warm weather. Consider coordinating this test with
operation testing of the releasing devices.
Caution ! Performance of this test will cause the
deluge valve (A1) to open and the sprinkler system to
fill with water.
To trip test the preaction system:
1. Notify the Authority Having Jurisdiction and those in
the area affected by the test.
2. To trip the deluge valve (A1):
♦ Fulfill the electric releasing condition (refer to
chapter 1.7.1).
♦ Open the sprinkler system inspectors test valve
or the main drain valve (D3).
♦ OR Open the door of emergency release (B10)
and pull the handle.
3. The deluge valve (A1) should open, filling the
sprinkler system with water. Water flow alarms
should operate.
4. Verify adequate flow from the sprinkler system
inspectors test valve within an acceptable time
period.
When trip testing is complete:
Perform steps 5 through 7 of chapter 4.5.
Perform steps 7 through 20 of chapter 4.6.
Notify the Authority Having Jurisdiction and those in the
affected area that testing is complete.
