Table D.3 NAC Wiring Requirements for FACP with FLPS-7 Power Supply
NOTE: Calculations are based on Direct-Current Resistance data for uncoated copper wire, per National Electrical Code (2005 Edition)
Table 8, Conductor Properties.
NOTE: These distances reflect the worst case scenario and are based on the current draw of the highest candela strobes at the low end of
the supported NAC voltage with the entire load at the end of the circuit. Further distances can be achieved by performing a point to point
voltage calculation that more accurately reflects the specific devices used and how they are dispersed on the circuit.
