Battery Power
The power cable is used to provide power from the batteries to the FX-4000MNS Fire Alarm
main board and the audio card cage motherboard. Power from the batteries is first directed to
the Battery Disconnect Board, from this board the power is connected to the main fire alarm
board and the audio card cage. The red and black wires are soldered on the audio card cage
and the spade ends are connected to the red (+) and black (-) connectors on the Battery
Disconnect Board. The extra positive and negative wires (from the Y power cable) are
connected to the spades on the main fire alarm board and the spade connectors from the
bottom of the Battery Disconnect Board are hooked up to the batteries, red (+) and black (-).
Refer to Figure 52.

Transformer Power
The orange, white, orange wires are soldered on the audio card cage motherboard. They are
connected to the terminal block located on the power supply cover (which covers the
transformer) in the order left to right, orange-white- orange. The orange-white-orange wires
from the transformer are connected to the top terminals located on the power supply cover in
the same order (orange-white-orange). The yellow wire is connected to the 240V terminal, the
red wire from the transformer (120V) is connected to the 120V terminal on the fire alarm
chassis, the black wire (from the transformer) connects to the N terminal and the green wire
(from the transformer) to the G (Ground) terminal all located on the fire alarm chassis. If using
240V supply connect the yellow wire to the 240V terminal, but do not connect the 120V red
wire. The brown wires are connected to the bridge located on the fire alarm chassis. Refer to
Figure 52.
