4.8 INSPECTIONS & TESTS
NOTICE: THE OWNER
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 and NFPA-72. At least annually, the system
shall be thoroughly inspected and tested for proper
operation by competent personnel.
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,
valve inspections, trip tests of deluge 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.

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 4.3).
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.
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.
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 EMERGENCY
INSTRUCTIONS.
Perform steps 7 through 20 of chapter 4.6 PLACING THE
SYSTEM BACK IN SERVICE AFTER OPERATION.
Notify the Authority Having Jurisdiction and those in the
affected area that testing is complete.
