Setup Guide — FF 120T
1
This guide provides basic instructions for an experienced
installer to install and set up the Extron FF 120T
speakers.
Step 1 — Power down
Power down all attached devices before proceeding.
Step 2 — Suspended ceiling installation
Remove the ceiling tile where the FF 120T speaker will be installed. Cut out a 12" section from
either end of the tile where the speaker will be installed as shown below.
Step 3 — Remove the terminal cover plate
Loosen the two screws (do not remove) on the speaker’s terminal cover plate and remove the
cover plate.
• If a 70 V/100 V line distribution amplier is being used, such as the Extron XPA 2001-70V or
XPA 2001-100V, the cover plate is no longer needed since the included CPX transformer
cover plate will be installed in its place.
• If a 70 V/100 V line distribution system is not being installed, retain the cover plate and
proceed to Step 6b of this setup guide.
NWhen the line distribution system’s 70 V/100 V CPX 120 transformer cover plate is not
being installed, refer to the FF 120 User’s Guide for further instructions.
Step 4 — Routing cables through the CPX 120 cover plate
The included CPX 120 cover plates mount to the speakers with the transformer side down.
NInstallation of conduit and conduit adapters should conform to all applicable building codes
and local ordinances.

Step 5 — Connecting wires to the CPX 120 terminal block
The transformer side of the CPX 120 cover plate has a 7-connector terminal block. Route the
two wires from the amplier through the cover plate hole to the transformer side. The black
negative (-) wire attaches to the “COM” terminal, and the red positive (+) wire attaches to the
desired terminal tap.
Pull the speaker wires from the conduit (where a conduit is used), strip
3/16" (5 mm) from the wire ends, keep the wire strands
together by twisting them (do not tin the wires), and
secure the wires to the appropriate taps on the terminal
block’s captive screw connectors as indicated on the
tap label. Use a small flat blade screwdriver to tighten
the terminal block screws. See the note below for
wiring an additional speaker(s).
NRoute speaker wires from the second speaker through the cover plate hole to the transformer
side and twist the black negative (-) wires together and twist the red positive (+) wires
together before inserting them into the terminal block. Additional speakers can be daisy
chained this way.
NBe sure to observe the 70 V or 100 V system designation as indicated on the label.
NInstallation in a plenum-rated environment requires a wire gauge of 14 AWG to 18 AWG.
Wiring two speakers in parallel requires that the maximum wire gauge not exceed 16 AWG.
In a single speaker installation the wire gauge should not exceed 14 AWG.
When using exible conduit, insert the conduit into the cover plate opening using an
appropriate conduit adapter and secure the conduit to the plate as shown below.

When using plenum speaker wire without a conduit, insert the wire through the cable clamp
adapter (included) and secure the adapter to the plate.
• If a seismic support line is being used, install the seismic anchor ring (included between
the conduit adapter and the CPX 120 cover plate as shown in the following illustration.
• If the CPX 120 transformer cover plate is being installed, proceed to Step 6a, otherwsie
proceed to Step 6b.
Step 6a — Connecting wires from the CPX 120 to the speaker
Strip 3/16" (5 mm) from the ends of the two speaker wire leads (+ and -) coming from the
transformer. Keep the wire strands together by twisting them (do not tin the wires), and
secure the wires to the speaker’s input terminals while observing the correct polarity.
Connect the red positive (+) wires to the + speaker terminal and connect the black negative (-)
wires to the - speaker terminal as shown below. Proceed to Step 7.
Step 6b — Connecting wires from a low impedance amplifier to the
speaker
Route the wires from the amplier to the speaker using the same procedure for routing speaker
wire (with conduit if applicable) through the cover plate as described in Step 5.
NThe existing cover plate must be used when wiring the speaker. Route the amplifier
wires through the cover plate opening. After connecting the wires to the speaker, as
shown below, replace the cover plate and tighten the 2 screws.
Strip 3/16" (5 mm) from the ends of the two speaker wire leads (+ and -) coming from the
amplier. Keep the wire strands together by twisting them (do not tin the wires), and secure
the wires to the speaker’s input terminals while observing the correct polarity.
Connect the red positive (+) wire to the + speaker terminal and connect the black negative (-)
wire to the - speaker terminal depending on whether one or two speakers are being connected,
as shown below.

Step 7 — Installing the speaker in the ceiling
Refer to the illustration below.
a. Replace the cover plate and tighten the two cover screws.
b. Install the T-rail crosspiece into the ceiling opening up against the cut tile.
c. Set the speaker into place so that the edges are hidden by the support rails.
Step 8 — Attaching the seismic support lines
If seismic support lines are being used, connect a line through the seismic anchor (or integrated
line retainer) on the cover plate and attach it to one of the seismic bendout tabs (the center tab is
preferred) located on either side of the speaker. Use a small screwdriver or similar tool to bend
out the tab.
NObserve all applicable building codes and local ordinances when installing the speaker.
Step 9 — Power up
After checking all speaker connections power up the amplier.
Anchor this end to a
suitable secure point.
Route the cable through
the seismic anchor ring
and bendout tab.
