If the runner is not in attendance at the proprietary supervising station, at what interval should two-way communications be established?

• A. 5 minutes
• B. 10 minutes
• C. 15 minutes
• D. 30 minutes

Answer: (C)

The main idea is maintaining a reliable line of contact with the proprietary supervising station when no one is physically at the site to supervise. If the runner isn’t in attendance, the system is set to reestablish two-way communications at a regular, fixed interval to ensure the supervising station can verify that the site is still monitored and that signals (alarm, trouble, or supervisory) are being transmitted properly. Fifteen minutes is chosen because it provides a prompt, yet practical cadence: it is frequent enough to catch problems or missed transmissions quickly, but not so frequent that it creates unnecessary traffic or workload for the monitoring station and on-site staff. Shorter intervals (like five or ten minutes) would be more burdensome without offering proportionally greater assurance, while a longer interval (like thirty minutes) could delay detecting issues or confirmations. So, when the runner isn’t present, establish two-way communication every fifteen minutes to keep continuous, reliable monitoring and status verification.
