How long should records be retained for smoke detectors tested over multiple years?

• A. 10 years
• B. 5 years of testing and 1 thereafter
• C. 3 years
• D. 7 years

Answer: (B)

Records for smoke detector testing kept over multiple years should cover five years of testing history plus one additional year after the last test. This approach ensures a complete, traceable history through several maintenance cycles and keeps documentation available for the next inspection or audit. The five-year window captures enough data to show performance trends, while the extra year provides a cushion after the most recent test. Shorter periods don’t give enough history, and longer periods aren’t required by typical regulations.
