Close the supply control valve. 2 Place the accelerator out of service by shutting the ball valves on either side of the accelerator 3 Shut off the air supply system. 4 Open the test dram valve. 5 Reneve system air pressure by opening the air sunply test valve 6. System and supply pressure gauges should now read zero psi 7 Open the dry valve, hand -hole cover. If the dry valve clapper is in the DOWN and LATCHED position, unlatch the clap- per arm by inserting the dry valve wrench through the hook -pawl assembly and apply downward pressure on the wrench handle. The clapper arm will be released and will swing to the full OPEN position. 8.

NORMAL CONDITIONS 1 All control valves open, locked and sealed with tamper proof seals. 2. ALARM TEST SHUT-OFF VALVE IN "ALARM" POSITION 3. Water and au pressure gauge valves open 4. Accelerator shut-off valves open 5. System air pressure and accelerator gauges indicating equal pressure 6 The water pressure -gauge reading equals that of the known service -line pressure 7 Incoming power to all alarm switches on 8 Test dram valve, auxiliary drain valves and inspector's test valves should be tightly closed 9 If an automatic air supply is used the compressor should be on the air maintenance device, the by-pass valve should be closed. and, the system air should be maintained at a constant pressure 10, The sprinkler head cabinet contains appropriate replacement sprinklers 11 Dry valve house temperature should be maintained above freezing. 12 Drum drips and low points should be free of water 13 The water level -n the nser must be below the au supply drain. C. WEEKLY TEST OF SYSTEM 1. Check the system for normal conditions ' 2. Turn Alarm Test Shut-off valve to Test position, water motor alarm should sound 3 Close Alarm Test Shut-off valve, the alarm will silence 4 Close accelerator shut-off valves and open air supply test valve until air flows, then close the valve quickly 5 Drain the water from drum drips (Close the top valve, then open the bottom valve antl drainclose the bottom valve, then open the top valve ) 6 Open accelerator shut-off valves (Dq3,
