Set tap by turning. Use a flat head screwdriver.

Preparing the Installation

Using a Safety Cable
Some regional construction codes require the use of a secondary method of securing loudspeakers to support structures to provide additional safety. Choose a mounting position, method, and hardware consistent with local building codes and regulations.
Bose Professional recommends using (1) a safety wire or (2) a safety cable as a secondary securing mechanism. See the diagrams below for safety attachment points.
Follow the manufacturer’s instructions for any secondary securing mechanism implemented.Assembling the Tile Bridge
Note: If you are installing in a hard ceiling, assemble the tile bridge after inserting the rails and ring through the hole cutout (see page 7).

1. Align the rails and insert the tabs into the slots.
2. Pull the rails outward to secure them together.
3. Align the rails parallel to each other and press the tile bridge ring down to secure the ring to the rails.

Note: Installation in close proximity to cooking surfaces where the loudspeaker may be directly exposed to cooking oils, such as in commercial cooking environments, may decrease the performance or functionality of the loudspeaker.
Preparing Acoustic Ceiling Tile

Cutting the Ceiling Tile

1. Remove the tile and use the template to trace a loudspeaker hole onto the tile. To center the template on the tile, draw an X by connecting the corners diagonally and center the template using the crossing point.
2. Cut a hole into the tile.

Installing the Tile Bridge

1. Place the assembled tile bridge across the ceiling grid. If necessary, adjust the tile bridge so the rails rest on the ceiling grid.
2. Replace the tile in the ceiling.

Installation

Preparing Hard Ceiling (Existing Construction)
Cutting the Ceiling

1. Use the template to trace a hole onto the ceiling.
2. Cut a hole into the ceiling.

Installing the Tile Bridge

1. Insert the tile bridge rails and ring through the hole and place the rails parallel to each other across the ceiling grid or ceiling furring.
2. Assemble the tile bridge.

Mounting the Loudspeaker

1. Pass the audio wire through the wire opening.
2. Insert the loudspeaker through the hole and into the tile bridge. Make sure the anchors engage on the tile bridge before loosening your grip on the loudspeaker.
3. Remove the connector, wire the connector, and reinsert the connector into the loudspeaker. For wiring information, see Wiring the Loudspeaker on page 5.
4. Tighten the anchor arm screws to secure the loudspeaker. If using a power drill, set to a low torque setting.

WARNING: Over-tightening the screws may result in damage to the anchor attachment point or the ceiling, which could lead to a falling hazard. Installing in Hard Ceiling Using a Rough-in Pan (New Construction)
For information on installing a rough-in pan, see the DesignMax Rough-in Pan installation guide at BoseProfessional.com. Once the rough-in pan is installed, see Mounting the Loudspeaker on page 7.
