FF 220T • Setup Guide
This setup guide contains installation information about the Extron FF 220T Flat Field
®
speaker. This speaker is designed for use
in plenum rated ceiling spaces and can be dropped into a standard square (2-foot by 2-foot or 600 mm by 600 mm) or rectangular
(2-foot by 4-foot or 600 mm by 1200 mm with supplied cross bars) false ceiling tile space on a T-bar grid.
WARNING: May result in serious injury. Installation and service must be performed by authorized personnel only.
NOTE: The FF 220T comes in two ceiling tile configurations depending on the tile unit of measurement:
• US version (part #42-141-03) Drops into 2 x 2 (61 cm x 61 cm) or 2 x 4 (61 cm x 122 cm) —' ' ' '
suspended tile ceilings
• Metric version (part #42-141-23)
— Drops into 600 mm x 600 mm or 600 mm x 1200 mm suspended tile
ceilings
Be sure to order the correct part number as the two configurations are not interchangeable and will not
fit correctly.
Factors to Consider Before Installation
zInstallation of conduit and conduit adapters must conform to all applicable
building codes and local ordinances.
zInstallation in a plenum-rated environment requires a wire gauge of
12 AWG to 18 AWG, as shown on the right. Conduit may be required.
zIf using secondary support cables, the installer provides the cables.
Installation
1. Disconnect power — Power down all attached devices before proceeding.
2. Remove and cut ceiling tile — Remove the square ceiling tile where the FF 220T will be installed. If the ceiling has
rectangular tiles, cut the tile in half, as shown below.

3. Install the T-rail in a rectangular tile — When the ceiling uses rectangular
tiles, install the T-rail crosspiece into the ceiling opening up against the
cut tile, as shown on the right.
4. Transformer cover plate — Loosen, but do
not remove, the two screws on the top of
the transformer cover plate, as shown on
the right. Next, slide and remove the
transformer cover plate, which is installed
with the transformer side down.

5. Route the cables through the cover plate —
Using a flexible conduit:
a. Route the wires through the conduit.
b. Insert the conduit into the cover plate opening
using an appropriate conduit adapter, and secure
the conduit to the plate, as shown below.
c. Pull the wires out of the conduit and through the
cover plate.
6. Distributed audio system (70 V or 100 V) or direct connection —
• if wiring a 70 V or 100 V distributed system and using the transformer, proceed to step 7.
• if bypassing the transformer and wiring directly from the amplier, proceed to step 9.
7. For 70 V or 100 V distributed audio systems, connect cables from the amplier to the transformer on the FF 220T transformer
cover plate.

c. Strip 3/16” (5 mm) from the wire ends and keep the wire end strands together by twisting them. Do not tin the wires.
d. Secure the wires to the appropriate taps on the captive screw
connectors of the 7-connector terminal block (on the transformer
side of the cover plate) as indicated on the tap label. See the note
below. The black, negative (-) wire attaches to the “COM” terminal,
and the red, positive (+) wire attaches to the desired terminal tap.
See the diagram at right.

positive (+) wires together before inserting them into
the terminal block. Additional speakers can be daisy
chained this way, as shown at right.
8. Connect wires from the transformer to the speaker.
a. Keep the wire strands together by twisting them (do not tin the wires).
b. Connect the red positive (+) wire to the + speaker terminal and connect the black negative (-) wire to the - speaker
terminal as shown below.
c. Proceed to step .10
9. For direct speaker connection, see the block diagram below.
a. Route the wires from the amplier to the speaker using the same procedure for routing speaker wire (and conduit if
applicable) through the transformer cover plate as described in steps 4 through 7b (see the wire gauge table on
page for maximum speaker wire sizes). Strip 3/16 inch (5 mm) from the ends of the two speaker wire leads (+ and -) 1
coming from the amplier. Keep the wire strands together by twisting them (do not tin the wires), and secure the wires to
the input terminals of the speaker while observing the correct polarity.
