Installation Output Circuits
The NAC Follower input is power-limited (Class 2) (refer to Section 2.12, “UL Power-limited Wiring Requirements”, on page 42) and
supervised by the host FACP. Supervision requires that a 4.7 K
Ω
EOL resistor be connected to the last device in the NAC Follower
chain.
2.5.4 Night Ring
The external audio input allows a building’s Private Branch Exchange (PBX) to activate the NFC-50/100. Connections need to be made
to TB16 on the main control board and to TB5.1 and TB5.2 on the display board. Refer to Section 1.2.2 for electrical specifications to
the external audio input.
