MS-5UD & MS-10UD Series Manual — P/N 52626:C7 6/12/2018 125
Appendix D: Wire Requirements
Connecting external system accessories to the main circuits must be carefully considered to ensure proper operation. It is important to
use the correct type of wire, gauge and run length for each circuit. Reference the chart below to specify wire requirements and limitations
for each circuit.
D.1 MS-5UD-3(E) & MS-10UD-3(E) NAC Wiring
The following table lists NAC wiring requirements for the MS-5UD-3(E) & MS-10UD-3(E) FACP which utilizes the FLPS-3 power
supply.

Table D.2 NAC Wiring Requirements for FACP with FLPS-3 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.
