Perform the water flow alarm test on a frequency required by the current NFPA-25 code. The authority having jurisdiction in the area may require
these tests on a more frequent basis. Verify these requirements by contacting the authority having jurisdiction in the affected area.

Notify the authority having jurisdiction, remote station alarm monitors, and those in the affected area that the water flow alarm test will be
performed.
2.
Open the water supply main drain valve fully to flush the water supply of any contaminants.
3.
Close the water supply main drain valve.
4.
Open the alarm test ball valve. Confirm that mechanical and electrical alarms are activated and that remote monitoring stations, if provided,
receive an alarm signal.
5.
Close the alarm test ball valve after verifying proper operation of all alarms.
6.
Push in the ball drip plunger on the alarm manifold assembly to verify that there is no pressure in the alarm line.
7.
Verify that all alarms stopped sounding, that the alarm line drained properly, and that remote station alarms reset properly.

Confirm that the ball drip on the alarm manifold assembly is not leaking water or air.
9.
Provide test results to the authority having jurisdiction, if required.
