Re-acceptance testing is required after which change to the system?

• A. Smoke detectors that have been added or removed
• B. Battery replacement
• C. Routine cleaning
• D. Tamper switch replacement

Answer: (A)

When the configuration of the fire alarm network changes in a way that alters which areas are monitored, re-acceptance testing is needed. Adding or removing smoke detectors changes coverage, wiring paths, and how the panel identifies devices and zones. Re-acceptance confirms that the panel properly recognizes the new devices, that each detector responds correctly to smoke, and that the overall signaling and fault conditions still behave as intended after the change. Routine maintenance like battery replacements or cleaning does not alter the monitored wiring or device list, so re-acceptance isn’t required for those tasks. Replacing a component such as a tamper switch is typically a routine maintenance action and would generally be tested for proper operation, but the key practice focus is that adding or removing detectors necessitates re-acceptance to verify system integrity.
