UL Listing Requirement
All control panel designs restrict the number of NAC devices installed in circuits based on the rated
current threshold. Some control panel designs further restrict the number of NAC devices installed in
circuits based on device synchronization in addition to the rated current threshold. These control
panel designs can reduce the population of NAC devices below the number of devices that would be
considered for the rated current threshold.
NAC outputs of the Sigma A-CP Fire Control Panel are not limited by conditions other than the
maximum rated current threshold. NAC outputs of the Sigma A-CP Fire Control Panel can operate
combinations of Kentec authorized NAC devices as long as the total load of NAC 1 and NAC 2 does not
exceed 4 A.
The following series of System Sensor NAC devices are compatible for use on the special application
outputs of NAC 1 and NAC 2 when operating each NAC output below 2.5 A:
