Integrated Fire Alarm Connection

The FX-2000MNS Chassis consists of the Network Fire Alarm main board and chassis.

Battery Power

The power cable is used to provide power from the batteries to the FX-2000MNS 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 50.

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 50.
