minutes of alarm operation at the end of the 24-hour period. Use battery Ah calculations to
confirm compliance. The formula shown below includes the calculation for 4 minutes of alarm
operation at the end of the 24-hour period, and a 15% contingency factor that allows for
depletion of battery capacity with age.
