When off-premises monitoring is provided, records of all signals, tests, and operations recorded at the supervising station shall be maintained for not less than ___ year(s).

• A. 1 year
• B. 2 years
• C. 3 years
• D. 5 years

Answer: (A)

When a central station handles off-premises monitoring, it keeps a running log of every signal, every test, and every operator action. This creates an audit trail that can be reviewed during inspections or investigations. Retaining those records for at least one year provides a practical window to verify that signals were received, tests were performed, and operations occurred as required without imposing an excessive archival burden. Longer retention isn’t mandated for this specific requirement, though other records or more stringent regulations in different contexts might call for longer periods.
