How is a tamper switch typically tested?

• A. By automatically triggering a self-test in the system
• B. By manually turning a valve and verifying the tamper signal is received; or by operations simulation
• C. By replacing the tamper switch with a new one
• D. By visual inspection only

Answer: (B)

Testing a tamper switch centers on confirming it actually detects tampering and communicates that event to the control system. The most reliable approach is to manually create a tamper condition—such as turning or moving the valve’s tamper actuator or using a controlled operations simulation—and then verify that the tamper signal is received by the panel or monitoring system. This demonstrates that the switch is functioning and that the system will respond properly if someone attempts to interfere with the valve or device. Relying on an automatic self-test isn’t the standard method here, because not all systems include that feature, and it may not prove that the tamper signal is correctly transmitted to the control equipment in real-world conditions. Visual inspection alone won’t confirm electrical signaling or annunciation, and simply replacing the switch is a repair action rather than a verification of proper operation.
