Complete records of all signals received shall be kept for at least ______ year(s).

Complete records of all signals received shall be kept for at least ______ year(s).

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (B)

Keeping a log of all signals received is about traceability and accountability in fire alarm operations. Maintaining complete records for at least one year provides a reliable window to review recent events, verify that signals were properly processed, and support investigations, maintenance actions, or audits. A zero-year retention would mean no history at all, which isn’t acceptable; longer periods aren’t required by this rule, though an organization may keep more if desired. Therefore, the minimum retention is one year.
