During initial and re-acceptance testing of wireless protection systems, what should be confirmed?

• A. Verify the wireless devices are connected to the network
• B. Confirm the introduction of a fault in any Class A or B radio-frequency-specifier pathway and result in a trouble indication at the alarm control unit
• C. Ensure battery levels are within range
• D. Record and finalize the test results

Answer: (B)

The main idea being tested is whether the wireless protection system is supervised for its communication link, so faults in the RF pathway are detected and reported to the control unit. During initial and re-acceptance testing, you need to verify that if the radio-frequency path between wireless devices and the alarm panel experiences a fault (such as interference, loss of signal, or device failure), the system generates a trouble indication at the alarm control unit. This shows the supervision design works and that any degradation in the wireless link will alert maintenance rather than go unnoticed, which is essential for reliable protection.

Class A and Class B pathways refer to how circuits are monitored and fault-tolerant in fire alarm systems. Verifying that a fault in either type of RF pathway triggers a trouble condition confirms that the system’s supervisory mechanism is functioning as intended across the supported pathway configurations. While other aspects like battery status or recording results are important, they do not demonstrate the required RF-link supervision focus addressed by this test.
