Installation in a Suspended Ceiling (Single Installer)
If a single installer is installing the SF 26CT speaker system, follow the steps in this section. Topics in this section include:
Installation Considerations
Preparing the Installation Location
Configuring the Speaker
Mounting the Speaker
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.
Preparing the Installation Location
1. Power down all attached devices before proceeding.
2. 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.
SF 26CT User Guide • Installation - Single Installer 3
Page 10
4. Attach two V-rails and one C-ring across the tile above the hole cut in step 3, as shown
V
below:
a. Assemble two V-rail half sections as follows: fit the tab of one end into the slot of
the other end, then open the V-rail until it locks together (see figure 2). 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.
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.

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.

opening. Secure the conduit to the plate with the locking nut and pull the speaker wires from the conduit.
NOTE: The cover plate has an alternate hole available by removing the knockout.
3. Strip 0.2 inches (5 mm) from the wire ends.
4. Attach the speaker wires to the captive screw connector depending on the
configuration, as illustrated by the following three methods.

Mounting the Speaker
1. Mount the speaker back can enclosure.
a. Insert the speaker through the bottom of the hole in the ceiling tile that was cut with
the wires out of the way.
Figure 14. Inserting the speaker back can
b. Clamp the speaker back can to the C-ring by using a Phillips screwdriver to tighten
the four locking arms to the C-ring.
Figure 15. Tightening the locking arms
SF 26CT User Guide • Installation in a Suspended Ceiling - Division of Labor 13
Page 20
NOTE: Each of the four locking arm screws uses an Opti-TorqueTM indicator.
e
The indicator releases a red plastic ring onto the screwdriver once the screw is tightened to the correct torque. Stop tightening any further when this occurs to avoid overtightening the locking arms to the C-ring.
Figure 16. Stop tightening when the red ring falls
ATTENTION:
To avoid damaging the speaker, do not overtighten the four screws.
Pour éviter d’endommager l’enceinte, ne serrez pas trop les quatre vis.
2. If required, attach a secondary support line.
a. Connect a secondary support line to the support loop on the the back of the
speaker enclosure, as shown here.
Anchor end to suitable secure points within th solid and permanent building structure.
Figure 17. Connecting a secondary support line
ATTENTION:
Do not allow any slack in the secondary support line.
Ne laissez pas de mou au niveau du filin de sécurité secondaire.
b. Replace the adjacent ceiling tile that was removed in step 4b on page 4.
3. Repeat steps 1 and 2 for each speaker being installed.

Installation in a Hard Ceiling
To install the SF 26CT in a hard ceiling (having no ceiling tiles), with the ceiling structure in place, follow the steps in this section.
Topics in this section include:
Preparing the Installation Location
Configuring the Speaker
Mounting the Speaker
Preparing the Installation Location
1. Power down all attached devices before proceeding.
2. Cut a hole for the speaker. Use the provided cutout template to outline the hole to be
cut in the ceiling as described below.
a. Mark the location on the ceiling where the center of the speaker will be placed.
b. Position the center hole of the cutout template directly over the center mark.
c. Trace a circle around the cutout template.
d. Cut out the traced circle.
3. Fold one C-ring assembly in half and insert it through the hole in the ceiling.
4. Unfold the C-ring and center it over the hole with the flat side down.
Figure 22. Installing the C-ring
5. Route the speaker wires through the ceiling hole.
Configuring the Speaker
Follow the steps in Configuring the Speaker on page 5.
