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 123T can

begin.

• Verify if ﬁberglass ceiling tiles are being used (see step 4d on the next page and

step 10 on page 21 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 22 for details on suspending the enclosure on a

smaller grid face).

Use the following procedure:

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. Configure the CS 120P for a U.S. or metric ceiling grid — For U.S. ceilings (2 feet

by 2 feet or 2 feet by 4 feet), leave intact the four tabs that are on one of the short ends

of the enclosure.

For metric ceilings (600 mm by 600 mm or 600 mm by 1200 mm) cut off the tabs.
