What is the minimum required secondary power for an emergency radio communications enhancement system?

• A. 6 hours
• B. 12 hours
• C. 24 hours
• D. 48 hours

Answer: (B)

Backup power for an emergency radio communications enhancement system is all about keeping critical communications up when the building’s main power fails. The system needs to stay online long enough for responders to manage the incident, evacuate if needed, and either restore power or switch to an alternate communications method. Twelve hours is the minimum duration specified because it provides a reliable window that covers typical outage scenarios without requiring excessively large and costly battery banks or generators. Shorter durations, like six hours, risk losing communications during longer incidents, while longer durations (twenty-four or forty-eight hours) go beyond the minimum and add unnecessary expense for most situations.
