A. Quarterly Water Flow Alarm Test
Quarterly testing of water flow alarms and performance of a main drain test is recommended and may
be required by the Authority Having Jurisdiction.
1. Notify the Authority Having Jurisdiction and those in the area affected by the test.
2. To test the local electric alarm (if provided) and/or mechanical water motor alarm (if provided),
OPEN the alarm test valve in the deluge valve trim.
a. Electric alarm pressure switches (if provided) should activate.
b. Electric local alarms should be audible.
c. The local water motor gong should be audible.
d. If equipped with remote station alarm signaling devices, verify that alarm signals were re-
ceived.
3. When testing is complete, CLOSE the alarm test valve.
4. Verify:
a. All local alarms stop sounding and alarm panels (if provided) reset.
b. All remote station alarms reset.
c. Supply piping to water motor alarm properly drains.
5. Verify that the alarm shut-off valve is OPEN, and the alarm test valve is CLOSED.
6. Verify that the outlet chamber is free of water. No water should flow from the drip check when the
plunger is pushed.
7. Notify the Authority Having Jurisdiction and those in the affected area that testing is complete.
B. Quarterly Main Drain Test
1. Notify the Authority Having Jurisdiction and those in the area affected by the test.
2. Record pressure reading from the water supply pressure gauge.
3. Verify that the outlet chamber of the deluge valve is free of water. No water should flow from the
drip check when the plunger is pushed.
4. Fully OPEN the flow test valve.
5. When a full flow is developed from the flow test valve, record the residual pressure from the water
supply pressure gauge.
6. When the test is complete, SLOWLY CLOSE the flow test valve.
7. Compare test results with previous flow information. If deterioration of the water supply is de-
tected, take appropriate steps to restore adequate water supply.
8. Verify:
a. Normal water supply pressure has been restored to the inlet chamber, the priming chamber,
and the release system. The pressure on the priming chamber water pressure gauge should
equal the system water supply pressure.
b. All alarm devices, and valves are secured in normal operating position. For normal operating
position, refer to trim charts and system data for the system used.
9. Notify the Authority Having Jurisdiction that the test is complete. Record and/or provide notifica-
tion of test results as required by the Authority Having Jurisdiction.
C. Annual Trip Test
CAUTION! Performing this test results in operation of the deluge valve. Water will flow into the sprinkler
piping and from any open sprinklers and/or nozzles. Take necessary precautions to prevent damage.
1. Notify the Authority Having Jurisdiction and those in the area affected by the test.
2. Fully open the flow test valve to flush away any accumulation of foreign material.
