Loosen, Do Not Remove
IMPORTANT:
Refer to www.extron.com for the complete
user guide, installation instructions, and
FF 120T • Setup Guide
specifications before connecting the
product to the power source.
This setup guide contains installation information about the Extron FF 120T Flat Field® speaker. This speaker is designed for use
in plenum rated ceiling spaces and can be dropped into a standard 2 feet by 2 feet or 2 feet by 4 feet (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.
Factors to Consider Before Installation
z All wiring and electrical connections must conform to all applicable building codes and local ordinances.
z Installation in a plenum-rated environment requires plenum rated cable or conduit.

Installation
1. Disconnect power — Power down all attached devices before proceeding.
2. Remove and cut ceiling tile — Remove the ceiling tile where the FF 120T will be installed. Cut out a 12-inch section from
either end of the tile where the speaker will be installed, as shown below.

When using speaker wires without a conduit, secure the cable clamp
adapter (included) to the transformer cover plate and insert the wires
through the clamp. Tighten the screws as shown at right.
6. Distributed audio system (70 V or 100 V) or direct connection —
• if wiring a 100 V or 70 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. Connect cables from the amplier to the transformer on the FF 120T transformer cover plate.

a. Pull the wires from the amplier through and out of the conduit, if a conduit is used.
b. Route the two wires from the amplier through the cover plate hole to the transformer side. See the wire gauge table on
page 1.
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.

Wiring to a Single Speaker
e. Use a small at blade screwdriver to tighten the terminal
block screws.
f. To wire additional speakers, route speaker wires
from the second speaker through the cover plate
hole to the transformer side. Twist the black negative (-)
wires together and the red 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 in step 9b below.
c. Proceed to step 10.
9. See the following block diagram.
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
1). Strip 3/16 inch (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 input terminals of the speaker while
observing the correct polarity.

a. Temporarily remove a ceiling tile adjacent to the speaker and set it aside.
b. Connect a secondary support cable through the secondary attachment point, and attach it to one of the bendout tabs
located on either side of the speaker.
c. Attach the other end of the cable to a sturdy part of the building (studs, roof struts, and so on).
d. For additional secondary support cables repeat as needed (see the FF120T User Guide for further details).
e. Replace the ceiling tile removed in step 12a.
