During initial and re-acceptance testing of wireless protection systems, what must be demonstrated?

• A. 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
• B. Verify the devices are functioning normally with no faults
• C. Document only battery status
• D. Ignore wireless faults during testing

Answer: (A)

Fault detection and proper indication of wireless communication issues during acceptance testing. In wireless protection systems, the RF link between devices must be supervised so that any fault or degradation in the path is quickly reported. During initial and re-acceptance testing, you must demonstrate that introducing a fault in any Class A or Class B RF pathway results in a trouble indication at the alarm control unit. This shows the system will alert personnel when the wireless link is compromised, maintaining visibility and reliability of the protection network. Why this is the best approach: proving fault detection and reporting ensures that a degraded or failed wireless path doesn’t go unnoticed, which is essential for life-safety systems. Merely showing devices operate normally with no faults doesn’t verify that a problematic RF path would be caught and signaled. Focusing only on battery status misses the broader requirement of link supervision, and ignoring wireless faults would violate testing standards and safety expectations.
