Control 226C/T INSTALLATION
The installation system has been designed so that the entire
installation can be accomplished from beneath the ceiling,
for instances when access above the tile is not possible or
practical. However, in some cases it may be easier with
removable ceiling tiles to access from both the top and bottom
of the ceiling tile during various phases of the installation.
Step 1 – Cut the Hole. Cutout the hole size either by tracing
the cardboard cutout template or with a circular cutter set to
the cutout sizes listed above. Pull the wiring through the
cutout hole.
Step 2 – Insert Backing Hardware Through the Hole.
Packaged with the speakers are two types of backing
hardware – a C-shaped backing-plate bracket and two tile
rails.
Suspended Ceilings – Insert the C-plate through the hole
cut in the ceiling tile. Place the C-plate around the hole with
the tabs located as shown on Figure 4. Insert the tile rails
through the cut hole in the ceiling tile. Snap the two rails into
the two tabs in the C-plate 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-bracket tabs by inserting a screw
though each tab into the rail. This can all be accomplished
from below the ceiling tile, if necessary.
FOR SAFETY: IMPORTANT TO USE BRACKETS.
ALL included support brackets – C-plate and tile rails
-- MUST be used when installing into suspended ceiling
tiles.
Tile Rails: The tile rails are designed to fit either standard
24-inch wide tiles or 600-mm wide tiles. The tile rail pieces
do NOT physically attach to the T-grid struts. Instead, the
inverted-V shape at the ends of the rails sit OVER the T-grid
strut. During normal operation, the rails are supported by
the edge of the tile. In the unlikely even that the tile comes
out or falls apart, the ends of the support rails are designed
to catch onto the T-grid, providing secure support to hold the
loudspeaker assembly in place.
Vibration Reduction: These loudspeakers can generate
substantial vibration, which can cause buzzing of the ceiling
materials or structure. Depending on the character of the
ceiling tile and structure, the installer might need to place
neoprene or other dampening material under the tile rails or
the edges of the tiles to eliminate rattles.
Cutout Placement: The tile rails are pre-punched with
attachment holes along their length. Placement is not limited
to the center of the tile as is the case with many other tile rail
support systems.
Non-Suspended Ceiling Types – The C-bracket can be
optionally used by itself to shore up the ceiling material and
to spread out the clamping force from the tab clamps. Insert
the C-plate through the cut hole in the ceiling and place it on
the back side of the hole before inserting the speaker.
