REQUIRED WATER FLOW ALARM TEST
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.
1.
Notify the authority having jurisdiction, remote station alarm
monitors, and those in the affected area that the water flow alarm
test will be performed.
CAUTION
• Use caution to prevent opening the system main drain valve
accidentally.
• Opening the system main drain valve will cause the valve to
operate.
Failure to pipe the system main drain valve to a proper wastewater
drain will result in property damage.
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.
8.
Confirm that the ball drip on the alarm manifold assembly is not
leaking water or air.
9.
Notify the authority having jurisdiction, remote station alarm
monitors, and those in the affected area that the valve is back in
service. Provide test results to the authority having jurisdiction, if
required.
