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.
Step 3 – Connect the Wiring to the Removable Locking Connector – Connect the
wiring to the removable locking connector that is INCLUDED with the speaker by
stripping the insulation back about 5 mm (about 3/16 inch), inserting the bare end of
wire into the connector and screwing down the hold-down screw until tight using a
small flatblade screwdriver. Tighten any unused screws to avoid vibration.
