This section describes current-loading and the process for determining the standby-battery rating and the NAC wiring length. Current loading calculations do not include the combined detector currents of the Sigma A-CP Fire Control Panel. These combined currents are negligible in comparison to currents of the fire control panel, ancillary devices and NACs and are therefore excluded from the current loading calculation.
Current-Load The current-load of the Sigma A-CP Fire Control Panel is limited to 4.5 Amps of the power supply and 7 AH or 12 AH of the standby-batteries. Each NAC output of the Sigma A-CP Fire Control Panel is load dependent and limited to a maximum load-current of 2.5A.
The calculation of total-current-loading during an alarm condition includes the sum of device-loads on each power output circuit of the Sigma A-CP Fire Control Panel. Power circuits of the fire control panel are provided on the terminals of NAC 1, NAC 2 and AUX 24V.
