REQUIRED WATER FLOW ALARM TEST
Refer to current, applicable local and national fire protection standards to perform water flow alarm tests. 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.
2. Verify that the alarm line ball valve (Item 13, page 7) is open. FOR FG AND SBSC TRIM: Verify that the alarm line monitoring ball valve(s) is/are
open (Item 14a, page 7).
3. Open the system test valve (Item 8, page 7) fully. Confirm that mechanical and electrical alarms are activated and that remote monitoring
stations, if provided, receive an alarm signal. NOTE: There may be a time delay if a Series 752 VdS Retarding Chamber Assembly is installed.
4. Close the system test valve (Item 8, page 7) after proper operation of all alarms is verified.
5. Verify that all alarms stopped sounding, that the alarm line drained properly, and that remote station alarm reset properly.
6. Push in the plunger of the restricted orifice/alarm line drain (Item 10, page 7). Verify that water is not flowing from the restricted orifice/alarm
line drain. If water is flowing, refer to Section VIII, Troubleshooting.
7. Confirm that all valves are in their normal operating positions (refer to the table to the left).
8. 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.
