Table 6.2 System Draw Current Calculations
* Maximum current draw for all NACs plus DC output from TB10 and TB2 is 3.0 A during standby.
† Value represents an SLC’s maximum current draw. Refer to device datasheets for individual current draws.
‡ The total regulated load current supplied to four-wire smoke detector and power supervision relays cannot exceed 1.25 A.
** Enter the total notification appliance draw from the Main Power Supply, excluding the current from APS-6R supplies. Refer to Device Compatibility Document.
†† Refer to manual and/or Device Compatibility Document. See Table 1.1, “Reference Documentation,” on page 7 for specific documentation part numbers.
