Step-by-Step Installation and Wiring

The installation system has been designed so that the entire installation can be accom- plished 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 Ceiling Hole. Cut out the hole size either by tracing the cardboard cutout tem- plate and cutting the hole or by using a circular cutter set to the cutout sizes listed above. Pull the wiring through the cutout hole.

Guide to the Pins for Connection - The locking input connector contains 7 terminals, as marked above the connector. The pin functions are listed on the label located on the terminal cover plate.

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.

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 upper 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
