C.5 NCA Connections
The NCA does not provide an annunciator power output terminal. Power for the LDM should be drawn from the FACP's main
Power
power supply. Refer to the appropriate FACP appendix in this manual.

C.6 AM2020/AFP1010 Connections
Connect the power run for the LDMs to MPS-24A TB3, Terminals 1 (+) and 2 (-). Maximum current is 1 amp. The power run to

2048A) or SIB-NET. The EIA-485 circuit must be connected to the SIB-2048A as illustrated below.
The SIB-2048A can support one EIA-485 circuit, capable of spanning 12,000 feet (3,600 m) @ 12 AWG (3.25 mm2), as illustrated
below, provided that the SIB-2048A is located in the center of the span illustrated below. A 120 ohm terminating resistor is required at
each end of the twisted pair.
