A Water Control Valve Assembly must have which feature?

• A. Remote supervisory position indication
• B. Listed indicating valve
• C. Drain valve
• D. Antifreeze solution

Answer: (A)

The main idea being tested is that the water control valve assembly must provide a remote indication of the valve’s position. This means there is a supervisory signal or device connected to the valve that communicates whether the valve is open or closed to a remote location, such as the building’s fire alarm control panel or a monitoring system. Having this remote supervisory position indication is crucial because it ensures that the valve status is known to responders and building personnel during an incident or during maintenance. Without remote indication, you could have a valve closed or tampered with without anyone nearby realizing it, which could compromise the sprinkler system’s ability to function when needed.

Other features listed—like a drain valve, a listed indicating valve, or antifreeze—might be part of some assemblies or used in specific situations, but they are not the feature that NFPA 13R requires as a universal standard for the water control valve assembly. The antifreeze option, for instance, is only relevant in frost-prone environments, and a listed indicating valve replaces the need for remote indication in some interpretations, but the defined requirement for NFPA 13R is the remote supervisory position indication.
