Which device is used to detect unauthorized valve operation?

Explanation:
The device used to detect unauthorized valve operation is a tamper switch. A tamper switch is wired to monitor a valve’s position and will trigger an alarm or notification if the valve is opened or closed when it shouldn’t be, helping ensure the valve remains in the correct, authorized state. This kind of monitoring is about security and proper control of the system. Drain is used to remove water and does not monitor valve movement. A waterflow alarm detects water movement to identify leaks or sprinkler activation, not whether a valve has been operated improperly. A backflow preventer protects against contamination but does not detect unauthorized valve operation.
