Total Standby Current
Total standby-current of the 7 AH standby-batteries must draw less than 225 mA to maintain
continuous standby operation for twenty-four hours followed by five minutes of alarm.
Total standby-current of the 12 AH standby-batteries must draw less than 400 mA to maintain
continuous standby operation for twenty-four hours followed by five minutes of alarm.
Current loading calculations do not include the combined IDC currents of the Sigma A-CP Fire Control
Panel. These combined IDC currents are negligible in comparison to fire control panel, ancillary device
and NAC currents of the Sigma A-CP Fire Control Panel and are therefore excluded from the current
loading calculation.
