If detenoration of the water supply is detected, take appropriate steps to restore adequate v.ater supply 9 Verify that normal water supply pressure and system pneumatic pressure have been restored, and that all alarm devices and valves are secured in normai operating position 10 Notify the Authority Having Jurisdiction that the test is complete. Record andfor provide notification of test results as required by the Authority Having Jurisdiction C. Priming Water Level, and Low Air Alarm Test Ouarterly testing is recommended to verify that water is NOT present above the Priming Level Test Valve in the dry valve trim. Quarterly testing of low air alarms is recommended. 1 Notify the Authority Having Jurisdiction and those in the area affected by the test 2 Close the water supply main control valve supplying the dry valve. 3 Open the main drain valve (located on the inlet of the dry valve). If the dry valve being tested is equipped with a Viking accelerator and external anti -flood device installed according to Viking Model E-1 Accelerator Trim Charts, performing steps 6 or 7 of this test will cause the accelerator to operate. A burst of air from the vent in the bottom of the accelerator will indicate operation of the accelerator However, with the water supply main control valve CLOSED and the main drain valve OPEN, operation of the accelerator should not trip the dry valve 6 Dry valve priming water level lest a. Verify that the water supply main control valve is closed and the main drain valve is open. b. Fully oper, the priming level test valve in the dry valve trim to check for the presence of water If an accelerator is installed. this may cause the dry valve to trip If the presence of water is detected, the system may not have been properly drained. Perform steps 1 through 3, and 11 through 15 of section 4-8 PLACING DRY VALVE IN SERVICE. and repeat this dry valve priming water level test. c If1when no water is detected and the test is complete, cortinue to step 8. 7 Low Air Alarm Test a Verity that the water supply main control valve is closed and the main drain valve is open b Gradually open the priming level test valve in the trim of the dry valve to simulate operation of the dry system. Observe and record the pressure at which the low air alarm operates. 8 Close the priming level test valve 9 If the dry valve being tested is equipped with a Viking accelerator and external anti -flood device: a Close the %" (15 mm) NPT anti -flood isolation valve NOTE: AIR WILL CONTINUE TO FLOW FROM THE ACCELERATOR AFTER IT HAS OPERATED UNTIL STEP "B" BELOW IS PERFORMED. to Loosen (use the appropriate wrench), and remove the accelerator air gauge to release pressure from the upper chamber of the accelerator. When the accelerator re -sets, re -install the accelerator air gauge. 10 Perform steps 13 through 20 of section 4-0 PLACING DRY VALVE IN SERVICE TRIP TESTS Partial Flow Trip Tests are conducted with the water supply main control valve partially closed to minimize the amount of water enter- ing the system during the lest Performance of a Partial Flow Trip Test is recommended during warm weather at least annually except when a Full Flow Trip Test is conducted Partial Flow Trip Tests may verify operation of equipment and devices but do not simulate operation of the system in fire conditions Full Flow Trip Tests are conducted with the water supply main control valve fully open. The dry valve is operated by opening the system test valve to simulate the opening of a sprinkler in fire conditions When the dry valve operatesthe sprinkler piping will be flooded with water. Performance of a Full Flow Trip Test is recommended during warm weather at least once every three years. More frequent testing may be required by the Authority Having Jurisdiction A. Full Flow Trip Test 1 Notify the Authority Having Jurisdiction and those in the area affected by the test NOTE: ALARMS AND ELECTRIC PANELS CONTROLLED BY AN ALARM PRESSURE SWITCH INSTALLED IN THE "ELEC- TRIC ALARM PANEL CONNECTION" CANNOT BE INTERRUPTED (SEE DRY VALVE TRIM CART). 2 Fully open the main drain (located on the base of the dry valve) to flush away any accumulation or foreign material. 3 Close the main drain. 4. Record water supply pressure and system pneumatic pressure. 5. Open the remote system test v?!ve to simulate operation of the dry system. Record.
