CONTROL 40 SERIES 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 below and pull the wiring through the cutout hole.

Control 42C:

4.1 inches (104 mm)

Control 47C/T:

11.1 inches (282 mm)

Control 47LP:

11.1 inches (282 mm)

Control 47HC:

12.1 inches (307 mm)

Control 40CS/T:

12.1 inches (307 mm)

Hole Cutout

Step 2 – Insert Backing Hardware Through the Hole. Packaged with the speakers are two types of backing hardware – a C-shapedbacking-plate bracket and two tile rails (except for the lightweight Control 42C which does NOT include 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 pointing upwards enabling the C-plate to lie flat on the tile. 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 through each tab into the rail. This can all be accomplished from below the ceiling tile, if necessary.

For safety when installing in suspended ceiling tiles, utilize all included brackets. Note that the lightweight Control 42C includes a C-ring only, which may be all that is required for some applications. If the application calls for tile rails, they are available separately as part number MTC-RAIL.

C-Bracket and Tile

Rail Positioned on

Ceiling Tile

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 event 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 address rattles from the ceiling materials.

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.

Two Landing Dog-Ears

All Control 40 Series Second Landing Loudspeakers (except the

Control 42C) are equipped with a two-landing dog ear suspension system enabling them to be used with ceiling tiles that are up to 70 mm

(2.75 inches) thick. If using Control 40 loudspeakers with ceiling tiles that are greater

than 54 mm (2.125 inches) thick, start with the dog ear in the second (top) landing to ensure clearance and ease of installation.
