3 GENERAL DESCRIPTION Globe Fire Sprinkler Corporation Alarm Check Valves are used in wet pipe fire sprinkler systems. They primarily serve a dual purpose in that they prevent a reverse flow of water through their bodies (non-return) and also provide for the use of a hydraulic fire alarm which is not dependent upon an electrical power supply for its operation. Through the use of a hydraulic retard chamber a time delay is provided to eliminate potential false alarms caused by fluctuating water supply pressures. Where constant pressure water supplies are used the retard chamber (time delay) is not necessary. By incorporating the use of electrical pressure switches, other supplemental alarms, annunciators, etc. may also be used. Globe Alarm Check Valves are designed and manufactured to the standards and/or requirements of Underwriters Laboratories Inc., Factory Mutual Approvals, The Loss Prevention Certification Board and the City of New York Department of Buildings, and they conform to the design/usage requirements of NFPA. IMPORTANT NOTES. Any alarm check valve should be carefully tested, examined, and cleaned periodically in accordance with NFPA It is most important to ensure a clean water supply free of debris and solid particles such as sand, gravel, or mud.. If, during the annual inspection of alarm check valves, sediment or free particles of matter are noted, a further examination of internal valve parts becomes necessary.. All deposits should be removed from all operating parts and ports. Vent holes through seat ring, Items and 2 (Page ), should be throroughly cleaned and flushed with clean water.. Where difficulty in performance is experienced, the manufacturer or his authorized representative shall be contacted if any field adjustment is to be made. OCTOBER 2 Page BULLETIN A.C.V.I.M., REV. #

6 Testing and Maintenance Flow Test at Main Drain Valve (Main Drain Test) Reference NFPA 2, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems. TESTING Before proceeding with any tests involving water flow, certain precautions need to be taken.. Check the location where the test connection discharges to make sure that all is clear and that there is no possibility of the water flow causing damage or injury. 2. Check the end of the test connection to make sure that it is unobstructed. To obtain a satisfactory test, there must be an unrestricted flow of water when the test valve is wide open.. Check for alarm connections to a central station or fire department. If such connections are found, give proper notice to the signal receiving station before proceeding with the test. Note: A main drain test will also operate local fire alarms - unless they are temporarily shut off. Testing Alarm Valve and Waterflow Alarm Devices NFPA 2 recommends that the alarm valve and its waterflow alarm devices be tested at least quarterly. The primary way to test this equipment is by opening the Inspectors Test Connection. This connection, generally located at the highest and most remote point on the system in relation to the alarm valve, consists of a test orifice and controlling globe valve. Opening of the globe valve (Inspectors Test Valve), and the subsequent discharge of water through the test orifice, simulates the operation of a sprinkler. Therefore, alarm devices should sound and/or operate when the Inspectors Test Valve is opened. An alternate means of testing waterflow alarm devices is to open the Alarm Test Valve provided as part of the alarm valve trim. It must be noted, however, that opening of this valve only tests the alarms; it does not test the operation of the alarm valve since the supply for the alarm test line is taken from a point below the alarm valve clapper (see respective trim drawings). This means of testing, therefore, should only be used when weather conditions or other circumstances prohibit using the Inspectors Test Connection. Note: If alarms connect to a central station or fire department, notify the signal receiving station when all tests have been completed. NFPA 2 recommends that a water flow test be made quarterly from the main drain valve at the system riser. The purpose of this test is to show whether or not the normal water supply is available to the system. By comparing static and residual pressure readings with those previously established, a main drain test can indicate the possible presence of closed valves or other obstructions in the supply piping. The procedure for conducting a Main Drain Test is as follows:. With the Main Drain Valve closed, note and record the reading on the lower Pressure Gauge at the Alarm Valve. 2. Open the Main Drain Valve slowly until it is wide open. Then, check to make sure that a full steady flow of water is discharging from the main drain pipe. Note: If a full steady stream is not discharging, check the main drain piping further for possible obstructions.. Allow the water to flow until the reading on the lower Pressure Gauge drops and stabilizes. Then, record this reading. Note: The first and higher pressure reading is the static pressure. The second, lower reading is the residual pressure with a given flow discharging from the main drain pipe.. Close the Main Drain Valve slowly. Caution: If alarms have been temporarily shut off, they must be returned to service. If alarms connect to a central station or fire department, notify the signal receiving station when the test has been completed.. Compare both pressure readings with previously established or normal readings. Note: If the readings compare favorably, the water supply may be considered satisfactory. If, however, the pressure readings vary to any great extent, the condition should be investigated to determine the cause. Some possible causes are: Partially or totally closed system control valves. Clogged or frozen water mains. Serious leakage at valves or mains. OCTOBER 2 Page BULLETIN A.C.V.I.M., REV. #

7 MAINTENANCE The Globe Alarm Check Valve and its related equipment should be examined periodically to ensure proper operation and trouble-free service. Several areas to be routinely inspected are: Clapper Facing. The rubber clapper facing should be checked for wear or damage, and to determine that it is free of dirt and other foreign substances. If found to be worn or damaged (e.g., foreign matter imbedded in the surface), the facing should be replaced. If it is dirty, it should be cleaned, but compounds which could damage the rubber facing must never be used. Seat Ring. The seat ring should be checked for nicks and for stones, dirt or other foreign matter lodged in the grooves or holes. It should be cleaned thoroughly. If the seat ring is found to be severely damaged, the complete alarm valve assembly should be replaced or returned to Globe for possible reconditioning. By-Pass Check Valve. The ¾" check valve in the external by-pass should be checked for clapper and seat condition. Retard Chamber. The outlet plug and drain plug assemblies should be checked for obstructions. The screens should be cleaned thoroughly. Alarm Line Strainer. The ¾" stainer in the alarm line of the constant pressure trim setup should be checked and cleaned thoroughly. Alarm Test Valve, Main Drain Valve & Inspectors Test Valve. All controlling valves which are normally closed when the alarm valve is in the set position should be checked to be sure that they are fully closed and not leaking. Alarm Valve & Trim. The overall setup should be checked for visible leaks and possible physical damage to the valve and connections (e.g., broken gauges). Resetting of System The Globe Alarm Check Valve is self-setting when testing procedures are followed. When sprinklers operate, however, there are certain procedures which must be followed for restoring the system to service.. Close the System Control Valve (OS & Y, PIV or other). Caution: In the event of a fire, the system control valve is to be closed only after it has been determined, positively, that the fire has been extinguished. 2. Close the Alarm Control Valve.. Open the Main Drain Valve. Note: It is necessary to drain the system only as required to allow for sprinkler replacement.. Replace the sprinklers which have operated.. Close the Main Drain Valve. Open the Inspectors Test Valve. Note: This valve is opened to permit air to be vented from the system as it is being filled with water. 7. Slowly open the System Control Valve. Caution: Open the valve only partially at the start of water flow into the system. Do not open it fully at this point. To do so may cause a water hammer to occur which could either damage the piping or trap large volumes of air within the system.. Continue filling the system until water discharges in a continuous stream from the Inspectors Test Connection. 9. Close the Inspectors Test Valve. 0. Turn the System Control Valve to its full open position, at the same time observing the Pressure Gauges. Note: The system is filled when both gauges are steady and have the same pressure reading.. Conduct a Main Drain Test to make sure the water supply is satisfactory (see Flow Test at Main Drain Valve). 2. Open the Alarm Control Valve.. Conduct a test of the alarm devices (see Testing Alarm and Waterflow Alarm Devices).. Seal, lock, or otherwise secure the System Control Valve and Alarm Control Valve in an open position (per NFPA 2). The system is now ready for service.. If alarms connect to a central station or fire department, notify the signal receiving station that the system has been returned to service. OCTOBER 2 Page BULLETIN A.C.V.I.M., REV. #
