CS 120P • Setup Guide
The Extron CS 120P is a plenum-rated enclosure for the Extron CS 1226T SpeedMount®Ceiling Speaker System. The CS 120P
enclosure can be installed in both U.S. and metric ceiling grid systems with tiles 2 feet by 2 feet (600 mm by 600 mm) or 2 feet by
4 feet (600 mm by 1200 mm). It is UL 2043 listed for use in air handling ceiling spaces only if used in conjunction with the CS 26T
speakers.
This setup guide contains installation information about the CS 120P and provides procedures for installing it in suspended and
hard ceilings.
WARNING:Incorrect installation can result in serious injury. Installation and service must be performed by authorized
personnel only.
NOTES:
• All wiring and electrical connections must conform to all applicable building codes and local ordinances.
• Mounting must conform to all applicable building codes and local ordinances.
Installing the CS 120P Enclosure
The CS 120P enclosure must rst be mounted in the ceiling and wired for use with the CS 26T driver assembly before the CS 26T
speakers can be installed.
The minimum ceiling thickness needed to secure the speaker is 3/8 inch (0.95 cm). The maximum ceiling thickness that can be
used is 1 and 9/32 inches (3.3 cm).
For multi-trade installations, see Division of Labor Installation on page 4.
Mounting the CS 120P in a Suspended Ceiling
1. Disconnect power — Power down all attached devices.
2. Verify the space where the CS 120P will be installed — Ensure that there is sufcient clearance above the ceiling tile
for the CS 120P to rest on top of the tile.
3. Congure the CS 120P for a U.S. or metric ceiling — For U.S. ceilings (2 feet by 2 feet or 2 feet by 4 feet), leave the
four tabs on the side of the CS 120P intact. For metric ceilings (600 mm by 600 mm or 600 mm by 1200 mm), cut off the
tabs.

4. Remove the adjacent tile — To facilitate the installation process, remove the tile adjacent to the ceiling tile where the
CS 120P will be installed.
5. 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 nd 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5b.

IMPORTANT:
Go to www.extron.com for the
complete user guide, installation
instructions, and specifications.

d. Trace a circle on the ceiling tile as follows:
For installations in ceilings that are NOT fiberglass or when installing the speakers in an open back
configuration: Trace a circle around the cutout template.
NOTE: The fiberglass tile adapters are not needed and can be discarded.
For installations in a 1-inch (0.25 cm) thick fiberglass ceiling 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.
1. Place the berglass tile adapter around the outer diameter of the template that was positioned in step 5c.
2. Trace a circle around the outer diameter of the adapter.
e. Cut out the circle traced in the ceiling tile.
f. Replace the tile in the ceiling.
6. Remove the cover plate — Loosen (do not remove) the two screws on the cover plate and remove it, as shown below.
Cover Plate
7. Route the cables through the cover plate — Use one of the methods described below as appropriate.
NOTES:
• The CS 120P is fully UL 2043 compliant only when it is used with a metal conduit or with plenum rated cables.
• Installation of conduits and conduit adapters should conform to all applicable building codes and local ordinances.
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
Using speaker wires without a conduit:
a. Secure the cable clamp adapter (included) to the
cover plate.
b. Insert the wires through the clamp and cover plate as
shown below.
c. Tighten the clamp screws.

8. Wire the CS 120P — Route the wires through the H-shaped opening in the CS 120P. Be sure to leave sufcient slack.
9. Replace the terminal cover plate — Reinstall the cover plate onto the CS 120P and tighten the two screws that were
loosened in step 6.

Attach the berglass tile adapter to the outer side of the lip of the port hole on the CS 120P as follows:
a. Cut four strips of adhesive tape (such as duct tape) to the appropriate size.
b. Attach each tape strip starting from the outer side of the CS 120P metal bafe, up and over the port ring adapter, then
down to the inner surface of the CS 120P metal bafe, as shown below.

NOTE: The tape strips must lie flat against all surfaces, with no ridges or raised edges.
11. Place the CS 120P into the ceiling grid — Place the CS 120P over the tile grid, so that the enclosure is safely supported
on the two short edges. Ensure that the hole in the tile is aligned with the hole in the CS 120P.
NOTE: 2' x 2' (600 mm x 600 mm) grid mounting is
the same as 2' x 4' (600 mm x 1200 mm) grid mounting.

13. See steps 5 through 11 and 13 through 15 in the CS 26T Setup Guide to complete installation of the CS 26T in the
CS 120P.
Installing the CS 120P in a Hard Ceiling
zIt is the responsibility of the installer to identify a suitable mounting location and provide the mounting hardware.
zThe CS 120P must be mounted as close as possible to the upper surface of the ceiling material.
zThe lip of the CS 120P should protrude into the hole cut for the speaker.
zDo not leave a gap between the CS 120P and the ceiling material.
Division of Labor Installation
zThe ceiling grid must be in place before the enclosure is placed.
zIf the tile will be installed later:
zStandard ceiling grid: The CS 120P can rest on the grid.
zMicro grid: The secondary attachment points should be used as the hanger suspension points (see step 12, above).
zSee Mounting the CS 120P in a Suspended Ceiling on page 1 for instructions on installing the CS 120P.
NOTE: When placing the CS 120P in a micro tile
grid without tiles, use the secondary attachment
points as hanger suspension points.
