Which of the following is not permitted for supervising station alarm systems?

• A. Immediately transmit
• B. Delay more than 10 minutes
• C. Use battery backup
• D. Use external circuits

Answer: (B)

Signals to a supervising station must be transmitted to the monitoring facility without unnecessary delay. Delaying more than a short, defined period—specifically more than 10 minutes—is not permitted because it would delay response and compromise safety. The system may rely on battery backup to keep power during outages and can use external circuits as the transmission path to the supervising station, but regardless of power or path, the alarm information must reach the supervising station promptly.
