Setup Guide — FF 120T

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 amplier 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 amplier 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 amplier 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

amplier. 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 amplier.

Anchor this end to a

suitable secure point.

Route the cable through

the seismic anchor ring

and bendout tab.
