The minimum required secondary power duration for an emergency radio communications enhancement system is how many hours?

• A. 8 hours
• B. 12 hours
• C. 16 hours
• D. 24 hours

Answer: (B)

Emergency radio communications enhancement systems must stay powered during a power outage, and the minimum duration of their secondary power is twelve hours. This ensures that radio coverage remains available for responders even if the main power is down for an extended period or there’s a delay in restoring power. Twelve hours represents the shortest reliable window that supports continued communications during the critical early stages of an incident. Shorter durations, like eight hours, could leave the system powerless during longer outages, while longer durations such as sixteen or twenty-four hours exceed the minimum and add more burden in terms of battery or charging requirements.
