Remote supervisory position indication is a required feature on which assembly?

• A. Water Control Valve Assembly
• B. Listed Indicating Valves
• C. Underground Gate Valve
• D. Wafer-Type Valves

Answer: (A)

Remote supervisory position indication is required on the Water Control Valve Assembly because this assembly is the main shutoff for a building’s sprinkler system and must provide a remote signal showing whether the valve is fully open or closed. This monitoring helps ensure the system is ready to operate and provides early notice of tampering or an abnormal valve position, which is essential for a low-rise residential system with limited monitoring elsewhere. The other options are not the assemblies that carry this specific remote indication requirement in NFPA 13R: underground gate valves are typically not used as the primary accessible control point for the system, wafer-type valves are a type of valve design rather than the control valve assembly with remote indication, and listed indicating valves have their own indicators but the remote supervisory requirement is specifically tied to the Water Control Valve Assembly.
