INTRODUCTION
The Series UM Universal Manifold Assembly is a complete manifold assembly that includes a flow switch, Universal Test and Drain (UTD) assembly,
system pressure gauge, and a pressure relief valve.
FLOOR CONTROL VALVE ASSEMBLY – The UM meets NFPA 13 requirements for “Floor Control Valve Assemblies” where check valves are not
required (i.e. pressure-reducing control valves that are recognized as checking devices) in multi-story buildings requiring zoning by floor, or whenever
separate control and floor zoning is specified. Typically, larger sizes are utilized on vertical risers where check valves are not required. Per NFPA 13
requirements, all UM assemblies contain a listed pressure relief valve, which is pre-piped to drain.
NOTICE
• NFPA 13 requires a test connection capable of providing a flow rate equal to or less than one sprinkler of the smallest orifice in the system.
• Drawings and/or pictures in this manual may be exaggerated for clarity.

DO NOT Adjust
Calibration Screw
Inside Hex Cap
• The 300-psi/21-Bar ARV is factory set to relieve at approximately 175 psi/12 Bar.
• The ARV may be reset to a higher pressure; however, it shall be reset to relieve at a pressure that is in
accordance with requirements of the local authority having jurisdiction (typically nominal 10 psi/0.7 Bar above
the expected normal system pressure).
• To reset the ARV, use an adjustable crescent wrench to turn the hex cap clockwise for a higher pressure setting
or counter-clockwise for a lower pressure setting. Use the calibrated lines on the stem for an approximate relief
pressure setting. One full turn of the hex cap will result in approximately 25 psi/1.7 Bar increase or decrease.
• DO NOT adjust the calibration screw inside the hex cap, as indicated in the drawing to the left.
• To verify the new setting, isolate the ARV and use a small hydrostatic pump attached to the supply. Increase
the pressure to 10 psi/0.7 Bar above the expected normal system pressure. Readjust the ARV, as needed, to
maintain a 10 psi/0.7 Bar higher relief setting.
NOTE: An ARV replacement kit is available for order. This kit includes the ARV, a hose, and two worm gear hose
clamps.

TESTING
Refer to NFPA 25, FM Datasheets, or any applicable local requirements to perform testing. 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.
Before proceeding with any tests involving water flow, the following precautions shall be taken.
NOTE: It is not necessary to remove the ARV to perform a hydrostatic test. The ARV may be adjusted temporarily to a pressure above the test
pressure. Verify that the ARV is returned to its normal setting after completing the hydrostatic test.
1. Check for alarm connections to a central station or fire department. If such connections are found, notify the authority having jurisdiction,
remote station alarm monitors, and those in the affected area before proceeding with testing. NOTE: A main drain test may also operate local
fire alarms, unless they are temporarily disabled.
2. Check the location where the test connection discharges to verify that all is clear and that there is no possibility of water flow causing property
damage or personal injury.
3. Check the end of the test connection to verify that it is unobstructed. To achieve a satisfactory test, there shall be an unrestricted flow of water
when the handle on the UTD is in the “DRAIN” (full drain) position.
4. Move the handle on the UTD to the “TEST” (flow through K-factor orifice) position. Verify that an alarm condition results within the timeframe
specified by the local authority having jurisdiction.
5. Move the handle on the UTD to the “OFF” (normal operating) position. NOTE: The ARV is located on the upstream side of the UTD and will
continue to vent excess system pressure with the handle on the UTD in the “OFF” (normal operating) position.
