Installation and Wiring

The Bosch mounting system has been designed so that, if necessary, the installation can be
done from beneath the ceiling. In some cases with a suspended ceiling grid, however, it may
be easier to access from both the top and bottom of the ceiling tile during the installation
process. Typical installation hardware needed for either suspended ceilings or sheetrock
ceilings is included. The ceiling speaker assembly is held in place by mounting tabs that
securely grip the ceiling material. Input wiring is attached to a removable terminal block
connector that can be prewired if necessary before speaker installation to speed up the
installation process.

Step 1 — Cut the Hole

For suspended tile or sheetrock ceilings, cut out the hole either by tracing the cardboard
template or with a circular cutter set to the appropriate cutout size. If the wire has been pre-
installed, pull the wiring through the cutout hole.

Figure 4: Cut ceiling hole

Step 2 — Install C-Ring and/or Tile Rails

All Bosch speakers come packaged with two types of backing hardware: a C-ring and two tile
rails. For suspended ceiling installations, insert the C-ring through the hole cut in the ceiling
tile. Place the C-ring around the hole with the tabs located as shown in Figure 5. Insert the tile
rails through the cut hole in the ceiling tile. Snap the two rails into the two tabs in the C-ring
and align the rails so that the ends extend OVER the T-channel grid on the side of the tile.
Secure the rails onto the C-ring tabs by inserting a screw though each tab into the rail, as
shown in Figure 5.

INSTALLATION NOTE: TILE RAILS AND C-RING
Each speaker comes with two tile rails which are designed to fit either standard 24-inch-wide
or 600-mm-wide tiles. It is important to note that the tile rail pieces do not actually attach to
the T-grid struts. The ends of the rails sit OVER the T-grid strut. Normally, the tile supports the
rails. The tile rails are pre-punched at regular intervals with holes along their length. This
allows the C-ring to be positioned at any point along the rail. If the tile comes out or falls
apart, the ends of the support rails fall onto the T-grid, which prevents the speaker assembly
from falling.
