Voice amp talk time

Voice amp talk time

• A. 10 hours
• B. 40 hours
• C. 2 hours
• D. 20 hours

Answer: (D)

Voice amp talk time is set by the battery capacity and how much power the amplifier draws while you’re speaking. On typical SCBA voice amplification systems, the battery is sized to cover an entire shift, which is about twenty hours of continuous talk on a full charge. Ten hours would be shorter than the standard spec, two hours would run out quickly during a shift, and forty hours would require an unusually large, heavier battery not common on standard gear. So twenty hours best matches the expected performance and provides reliable operation across a full shift.
