Weather-resistant Input Cover

The weather-resistant input cover is designed for three different wiring scenarios (see above). To change the configuration of the input cover to support your wiring scenario, cut along the perforation on the rubber conduit.

• Indoor-only applications do not require the use of the input cover.
• If installing the loudspeaker with the rubber conduit facing upward, it is the installer’s responsibility to seal against water ingress into the Euroblock connector.
• If using the wide open rubber conduit configuration, it is the installer’s responsibility to seal against water ingress into the Euroblock connector.

Wiring the Loudspeaker

Wire Gauge

The FreeSpace FS4SE loudspeaker is designed to work with 18 AWG (0.8 mm2 ) to 14 AWG (2.1 mm2 ) size wire only.

Connection Diagrams

Expose six millimeters (1/4 inch) of bare wire to attach to the terminals.

• The loudspeaker is not rated for use with a rigid conduit. The loudspeaker is suitable for a flexible conduit or wiring connection only.
• Wiring method must be in accordance with: In Canada, CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, Section 32; In the United States, The National Electrical Code, NFPA 70.

Loudspeaker Settings

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.
• A safety cable can be attached to the loudspeaker using the threaded inserts on the sides of the enclosure.
• See the diagram to the right for safety attachment points.
• The side inserts (1) are sized for M8 screws with a depth of 10 millimeters (0.39 inches).

Loudspeaker Orientation

Choose the loudspeaker orientation best suited for your installation.

1. Horizontal
2. Vertical

Installing the Bracket

• When choosing an installation location, at least two of the mounting bracket’s attachment points must be secured to a support structure. Attachment points not secured to a support structure must be secured using appropriate hardware for the installation.
• Choose fasteners that are consistent with all local building codes and requirements.

Choose appropriate fasteners to support the weight of the loudspeaker (3.42 kg [7.55 lb]).

1. Mark the drill holes.
2. Drill four holes (sized for appropriate fasteners) into the wall.
3. Secure the bracket to the wall with two screws (not included). Note: Use M6 or 1/4″-20 sized screws.

Wiring the Connector

1. Feed the wires through the center hole of the bracket.
2. Insert the wires through the bottom of the input cover. See Preparing the Input Cover on page 4.
3. Wire the connector. For wiring information, see Wiring the Loudspeaker on page 5.

Ceramic Terminal Attachment Point

Installing the Loudspeaker

1. Attach the wired connector to the loudspeaker.
2. Place the input cover over the connector and press it firmly against the loudspeaker to create a tight seal. Use the two included input cover screws to secure the input cover.
3. Hold the loudspeaker in between the bracket arms and insert one of the included bracket screws into each side of the loudspeaker using the threaded inserts.
4. Align the pins on the mounting bracket with the angle slots appropriate for your installation and snap the bracket into the loudspeaker.
   • The angle of the loudspeaker can be adjusted to 0°, ±15°, ±30°, or ±45°.
   • In outdoor applications, do not install the loudspeaker with an upward pitch.
5. Tighten the screws on both sides of the loudspeaker to secure the loudspeaker to the mounting bracket. Do not over-torque the screw.
6. Locate the extended grille tab on the inside of the grille. Attach the grille by sliding it into place. Be sure the extended grille tab attaches to the grille lock on the loudspeaker enclosure.

Removing the Grille

The grille is secured to the loudspeaker by the grille lock. Disengage the grille lock by inserting a small tool through the grille perforation (no larger than 1.5 millimeters in diameter). While depressing the grille lock, slide the grille away from the loudspeaker to detach it.

• The grille lock is located on the loudspeaker opposite the tap switch. See the diagram below for the grille lock location.

Adjusting the Logo

The FreeSpace FS4SE comes with a pre-installed Bose logo for horizontal installations. The loudspeaker also comes with a separate logo for vertical installations. To remove the logo, peel it away from the loudspeaker grille. To apply the vertical logo, find the center of the grille and align the notches on the back of the logo with the grille perforation. Press to affix it to the loudspeaker grille.
