Which action statement is consistent with re-acceptance testing after changes to a fire alarm system?

• A. Optional visual inspection only
• B. Battery replacement only
• C. Fast-tracked installation without testing
• D. Re-acceptance testing

Answer: (D)

After changes to a fire alarm system, you must perform re-acceptance testing to confirm the system still meets the required performance criteria and that all modifications are properly integrated. This testing verifies that initiating devices trigger the correct alarms, notification appliances operate as intended, supervision and fault indications function, and the power supply remains within specification. A visual inspection alone cannot prove proper operation, and replacing a battery by itself doesn’t demonstrate the system responds to inputs or that all functions remain correct. Skipping testing or rushing installation without testing fails to show the system meets code and the owner’s safety needs. Re-acceptance testing is the appropriate, required step after changes.
