Introduction  
This section gives an overview of the Extron CS 1226T SpeedMount Ceiling Speaker  
System, consisting of the CS 26T speakers and CS 120P enclosure. It also provides a list of  
system features and an application diagram. Topics include:  
About this Guide  
This guide describes the Extron CS 1226T Speaker System, the CS 26T speaker pair and  
the CS 120P enclosure and provides instructions for installing all components of the system  
in different types of ceilings.  
Overview  
The CS 1226T system features a low profile design that houses a 6.5-inch woofer and a  
0.75-inch tweeter (CS 26T) contained in a UL 2043 rated enclosure (CS 120P) designed for  
use in plenum rated ceiling spaces.  
This unique speaker system splits installation into two phases, rough-in and finish, allowing  
the installer to “reserve” space for the speaker system by installing the CS 120P back can  
and then later installing the CS 26T speaker. This two-step process (division of labor) is  
especially useful when multiple installers are involved. The CS 120P can be installed by the  
low voltage contractor while the CS 26T can be installed by the AV systems contractor.  
Features  
US and metric ceiling grids — The CS 120P enclosure can be installed in both U.S.  
and metric ceiling grid systems (for metric systems, the CS 120P end tabs are cut off).  
UL 2043 listed — The CS 1226T is UL 2043 listed (only when the CS 26T is used with  
the CS 120P).  
NOTE: The use of any other back can other than the CS 120P or those provided by  
Extron voids the UL 2043 rating.  
Optional open back configuration — The CS 26T can be used without the CS 120P  
by reconfiguring the attached bass port plate (allowing the CS 26T to function as an  
open back speaker).  
NOTE: When the CS 26T is used without the CS 120P, it is not suitable for air  
handling spaces and is not UL 2043 rated.  
New dog-leg design — The new dog-leg design eliminates jamming during  
installation.  
Low profile enclosure — The low profile enclosure is compatible with plenum  
environments where overhead space may be limited.

Selectable taps — The rotary tap selector switch, located behind the grille, sets the  
speaker to operate in either 8-ohm direct or 70 volt /100 volt operation with 16, 8, 4, 2,  
and 1 watt taps.  
Magnetic grille — Magnets spaced around the grille edge enable it to be easily  
attached and to remain firmly in place.

Installation  
This section provides instructions for installing the CS 26T speakers and the CS 120P  
enclosure. Topics include:  
Installation Considerations  
WARNING: Risk of severe bodily injury from falling or sharp equipment.  
Installation and service must be performed by authorized personnel only.  
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 CS 26T can be configured in the following ways:  
Open-back: For configurations in which the CS 120P is not used, use the C-ring  
accessory, available at www.extron.com. The C-ring spreads out the clamping force of  
the dog-legs when used in drop ceilings and gypsum ceilings.  
Using the CS 120P: When used with the CS 120P, the CS 26T can be placed in  
plenum environments. This is the only configuration that is UL 2043 rated.  
NOTE: The CS 120P can be ordered separately or as part of the CS 1226T kit.  
For hard ceiling installations, see Installing the CS 120P in a Hard Ceiling on  
page 26.

Installing the CS 1226T System — Single Installer  
If a single installer is installing the CS 1226T system, follow this procedure for the entire  
system:  
NOTE: The ceiling grid must be installed before the installation of the CS 1226T begins.  
Verify if fiberglass ceiling tiles are being used (see step 2 below and step 11 on  
page 7 for details).  
The grid face must be at least 15/16 inch (24 mm) for proper installation of the  
CS 120P (see step 20 on page 13 for details on suspending the enclosure on a  
smaller grid face).

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 CS 26T 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 on the ceiling tile as follows:  
For installations in ceiling tiles that are NOT fiberglass or when installing  
the speakers in an open back configuration: Trace a circle around the CS 26T  
cutout template.  
NOTE: The fiberglass tile adapters are not needed and can be discarded.  
For installations in 1-inch (0.25 cm) thick fiberglass ceiling tiles with the  
CS 120P:  
NOTE: A set of fiberglass tile adapters is provided with both the CS 26T and  
the CS 120P. Only one set is needed to install the CS 26T with the CS 120P  
kit in a 1-inch (0.25 cm) thick fiberglass tile. The adapter works only with  
1-inch (0.25 cm) thick fiberglass tile.

Installing the CS 120P in a Suspended Ceiling — Division of Labor  
In a division of labor installation, low-voltage contractors install the CS 120P enclosure  
(construction rough-in phase).  
NOTE: The ceiling grid must be installed before the installation of the CS 1226T can  
begin.  
Verify if fiberglass ceiling tiles are being used (see step 4d on the next page and  
step 10 on page 18 for details).  
The grid face must be at least 15/16 inch (24 mm) for proper installation of the  
CS 120P (see step 12 on page 19 for details on suspending the enclosure on a  
smaller grid face).
