To test electric alarms (if provided) and/or mechanical water motor gong (if provided), OPEN the system test valve. If freezing weather or other conditions prohibit use of the system test valve, OPEN the alarm test valve in the alarm check valve trim. NOTE: USE OF THE ALARM TEST VALVE ALLOWS TESTING OF ALARMS WITHOUT REDUCING THE SYSTEM PRESSURE. a. Electric alarm pressure switches should activate. b. Electric local alarms should be audible. c. The local water motor alarm should be audible. NOTE: WHEN USING THE SYSTEM TEST VALVE FOR THE WATER FLOW ALARM TEST, INTERMITTENT OPERATION OF THE WATER MOTOR ALARM MAY INDICATE AIR IS TRAPPED IN THE SYSTEM (REFER TO THE PLACING THE SYSTEM IN SER- VICE PARAGRAPH OF SECTION 4). d. Verify that remote station alarm signals (if provided) were received. 3. When testing is complete, close the test valve used. 4. Verify: a. All local alarms stop sounding and electric panels (if provided) reset. b. All remote station alarms reset. c. Retard chamber and water motor alarm supply piping has drained properly. 5. Verify that the alarm shut-off valve in the Alarm Check Valve trim is OPEN, the alarm test valve is CLOSED, and all valves are in their normal operating position and appropriately secured. 6. Notify the Authority Having Jurisdiction, remote station alarm monitors, and those in the affected area that testing is complete. Main Drain Test Semi Annual performance of the Main Drain Test is recommended and may be required by the authority having jurisdiction to verify integrity of the water supply. 1. Notify the authority having jurisdiction, remote station alarm monitors, and those in the area affected by the test. 2. Perform monthly visual inspection. 3. Verify that adequate drainage is provided for full flow from Main Drain outlet. 4. Record pressure reading from the water supply pressure gauge. 5. Fully OPEN the main drain located on the Alarm Check Valve. 6. When a full flow is developed from the main drain, record the residual pressure from the water supply pressure gauge. 7. When the test is complete, SLOWLY CLOSE the main drain. 8. Compare test results with previous flow information. If deterioration of the water supply is detected, take appropriate steps to restore adequate water supply. 9. Verify that normal water supply pressure has been restored, and that all alarm devices and valves are secured in normal operat- ing position. 10. Notify the Authority Having Jurisdiction, remote station alarm monitors, and those in the area affected by the test that the test is complete. Record and/or provide notification of test results as required by the Authority Having Jurisdiction. Five -Year Internal Inspection (Refer to Figure 3) Internal inspection of Alarm Check Valves is recommended every five years unless inspections and tests indicate more frequent inter- nal inspections are required. 1. Notify the Authority Having Jurisdiction, remote station alarm monitors, and those in the area affected that the system will be taken out of service. Consideration should be given to employment of a fire patrol in the affected areas. 2. Close the water supply Main Control Valve, placing the system out of service. 3. Open the main drain. If necessary, open the system test valve to vent and completely drain the system. 4. Use appropriate wrench to loosen and remove cover screws (15), and remove Cover/Clapper assembly (2-12). 5. Inspect water seat (13). Wipe away all contaminants, dirt, and mineral deposits. Clean any orifices in the seat that are restricted or plugged by mineral deposits. DO NOT use solvents or abrasives. 6. Inspect cover/clapper assembly (2-12) and cover gasket (14). Test hinged clapper (9) for freedom of movement and spring (6) for tension retention. Spring (6) tension should engage when the top of hinged clapper (9) is moved from perpendicular to cover (2) toward the open (flow) position. Renew or replace damaged or worn parts as required. A CAUTION Never apply any lubricant to seats, gaskets, or any internal operating parts of the valve. Petroleum -based grease or oil will damage rubber components and may prevent proper operation. 7. When internal inspection of the alarm check valve is complete, perform step 6 of the Maintenance paragraph in section 5 to re- install Cover/Clapper Assembly (2-12). 8. Place the wet system back in service, Refer to the Placing the System in Service paragraph in section 4. Form No. F_062293 18.10.18 Rev 18.1.P65
