4007ES Power Supplies
Introduction This chapter describes the common sections of both the 4007ES Hybrid NAC power supply
and the 4007ES IDNAC power supply.
Wiring Guidelines Class A wiring allows devices to communicate with the FACP even in the event of a single
open circuit somewhere on the loop. Class A wiring requires that two wires are routed from
the power supply to each device, and then back again to the power supply.
Class B wiring allows “T” tapping, and therefore requires less cable distance per installation
than Class A.
Auxiliary power only: Supervision must be provided if the auxiliary power circuit is to be
wired as a power-limited circuit. In order to connect a circuit using PL wiring, the devices
being powered must all be addressable, or a UL Listed EOL relay must be used to supervise
the circuit.
