About this Guide

This guide describes the SF 3C LP and SF 3CT LP speakers and provides instructions for
installing all components of the system in different types of ceilings.

NOTE: Observe all applicable building codes and local ordinances when installing the

speaker.

Overview

Features

The Extron SoundField SF 3CT LP and SF 3C LP are full-range ceiling speakers with 4-inch
(10.2 cm) low profile composite back cans for use in plenum rated ceiling environments with
limited vertical clearance above the ceiling.

The SF 3C LP supports 8 ohm operation. The SF 3CT LP supports 70 V, 100 V, and 8 ohm
direct operation. The SF 3CT LP has a 6-position rotary switch for selecting the various
power taps for 70V, 100V, or 8 ohms. The two models are physically similar, with slight
variations in weight and front baffle appearance.

The SF 3CT LP and SF 3C LP meet stringent UL 2043 requirements for smoke and heat
release in plenum air spaces. The 3-inch (7.6 cm) full-range driver features a frequency
range of 65 Hz to 20 kHz and a conical dispersion of 165 degrees. The SF 3CT LP and
SF 3C LP feature a thin-edged bezel and a magnetically attached grille.

• 4-inch (10.2 cm) deep low profile composite back can for plenum environments

• 3-inch (7.6 cm) full-range driver with a tuned port

• Frequency range: 65 Hz to 20 kHz

• 165-degree conical dispersion

• 16 watts continuous pink noise, 32 watts continuous program

SF 3C LP and SF 3CT LP User Guide • Introduction 1

• SF 3CT LP — 8 ohm direct or 70/100 volt operation on a 6 position, behind-the-grille

selector

• 8 ohm direct

• 70 volt: 16, 8, 4, 2, and 1 watt selectable

• 100 volt: 16, 8, 4, and 2 watt selectable

• SF 3C LP — 8 ohm direct

• White grille and bezel are paintable to match the installation environment

• Separable back can and baffle supports single-trade and division-of-labor installations

• Modular V-rail and folding C-ring kit

• Cable/conduit access plate can be oriented for side or top connections

• Opti-Torque indicator rings prevent overtightening of locking arm screws

• Three locking arms for quick ceiling installation

• Thin bezel and magnetically attached grille

• UL 1480 and UL 2043 plenum-rated enclosure

• Dimensional and weight savings, reduces overall storage and shipping costs

SF 3C LP and SF 3CT LP User Guide • Introduction 2

Installation

This section provides instructions for installing the SF 3C LP and SF 3CT LP speakers.
Topics include:

• Installation Considerations

• Installation Configurations

• Installing the Speaker System in a Suspended Ceiling — Single Installer

• Installing the Speaker System in a Suspended Ceiling — Division of Labor

• Installing the Speaker System in a Hard Ceiling

• Troubleshooting: Signal Test Points

Installation Considerations

WARNING: Potential risk of severe injury. Installation and service must be performed

by authorized personnel only.

AVERTISSEMENT : Risque potentiel de blessure grave ou de mort. L’installation

et l’entretien doivent être effectués par le personnel autorisé uniquement.

• All wiring and electrical connections must conform to all applicable building codes and

local ordinances.

• Installation in a plenum-rated environment requires plenum rated cable or conduit.

• If using secondary support cables, the installer provides the cables.

Installation Configurations

The SF 3C LP and SF 3CT LP can be configured for the following ceiling types:

• Suspended ceiling: The following sections describe speaker installation procedures for

suspended ceilings.

• Hard ceiling: For hard ceiling installations, see Installing the Speaker System in a

Hard Ceiling on page 23.

SF 3C LP and SF 3CT LP User Guide • Installation 3

Installing the Speaker System in a Suspended Ceiling — Single Installer

SF 3C LP and SF 3CT LP User Guide • Installation

If a single installer is installing the speaker system, follow this procedure for the entire system:

1. Disconnect power — Power down all attached devices before proceeding.

2. Verify the space where the system will be installed — Ensure that there is sufficient

clearance above the ceiling tile for the unit to be installed.

3. Cut a hole for the speaker — Use the provided cutout template to outline the hole to

be cut in the ceiling tile as described below.

a. Remove the ceiling tile.

b. To find the center of the tile, use a tape measure to measure the space between

two opposite corners, and mark the half-way point.

c. Position the center hole of the cutout template directly over the center of the tile

that you marked in step3b.

d. Using the provided cutout template, trace a circle around the

cutout template.

e. Cut out the circle traced in the ceiling tile.

f. Replace the tile in the ceiling.

4. Attach two V-rails and one C-ring across the tile above the hole

cut in step 3, as described below.

a. Assemble two V-rail half sections so that they become one single piece:

i. Fit the tab of one end into the slot of the other end.

ii. Open the V-rail until it locks together.

iii. Repeat this procedure for the other V-rail.

Figure 2. Assembling the V-rails

b. Remove a ceiling tile adjacent to the tile with the hole.

V

SF 3C LP and SF 3CT LP User Guide • Installation

c. Place both assembled V-rails on the cut ceiling tile and position them equally on

either side of the hole. The ends of the V-rails go over the ceiling grid.

d. Position the C-ring assembly on the two V-rails so that the C-ring is centered over

the hole, as shown below.

C-ring

-rail

Figure 3. Positioning the C-ring assembly on the V-rails

e. Secure the C-ring to the V-rails using two screws.

5. Route the speaker wires through the ceiling tile hole.

6. Configure the cable conduit access plate and captive screw connector.

a. If two conduits are being used, knock out the alternate knockout.

i. Place the head of the screw driver on the notch of the knockout.

ii. Tap the back of the screwdriver until the knockout pops out.

b. Loosen the two side cable conduit access plate screws and remove the plate

before wiring the speaker.

SF 3C LP and SF 3CT LP User Guide • Installation

When not using conduit: Route the speaker wires through the cable clamp.

When using conduit: Remove the cable clamp and install the conduit into the

plate opening. Secure the conduit to the plate with the locking nut and pull the
speaker wires from the conduit.

NOTE: The plate has an alternate hole available by removing the knockout. See

step 6a on the previous page to remove the knockout.

d. Strip 0.2 inches (5 mm) from the wire ends.

e. Attach the speaker wires to the captive screw connector depending on the

configuration, as illustrated by the following three methods.

Wiring Multiple Speakers Using Loop-through
When a chain of speakers is wired this way, disconnecting
one speaker removes power from all downstream speakers.

ATTENTION:

• Do not tin the wire leads before installing into the connector. Tinned wires

are not as secure in the connector and could be pulled out.

• Ne pas étamer les conducteurs avant de les insérer dans le connecteur.

Les câbles étamés ne sont pas aussi bien fixés dans le connecteur et
pourraient être retirés.
