Installation

Prepare Ceiling

Refer to Figure 3.

1. Use the template provided to mark and cut a hole (1) in the ceiling where the loudspeaker is to be installed. For frame-construction ceiling, skip to “Wire the Loudspeakers”.

2. Install two telescoping tile rails (2), one on each side of the hole and supported by the suspended-ceiling support rails (3).

3. Install the C-ring (4) over the hole using the tile-rails as support. Make sure the clips on the C-ring are properly ﬁtted over the tile-rail.

4. Use the tile rail screws (5) to secure the C-ring to the tile-rails.

IMPORTANT! If tile rail screws are not used, unwanted sag to the tile may occur.

Wire the Loudspeakers

1. Back out the conduit cover's Phillips retaining screw to its stop point and pull the conduit cover straight out to remove as shown in step 1 of Figure 4.

2. Pass the CAT cable through the conduit/stress-relief clamp, leaving enough wire for making connections as shown in step 2 of Figure 4. Carefully tighten the clamp over the wires, or over the

conduit if used.

3. Plug the RJ45 connector securely into the jack as shown in step 3 of Figure 4.

4. Reattach the conduit cover and secure with the Phillips retaining screw as shown in step 4 of Figure 4.

Mount the Loudspeaker

Refer to Figure 5.

1. Make sure all of the dog-ears are fully extended and in their non-capture position.

2. Position the loudspeaker into the hole prepared in the ceiling.

3. Use a Phillips screwdriver to tighten each of the three dog-ear screws.

4. As you tighten the screws, the dog-ears will swing into capture position over the ceiling. Be sure all dog-ears are properly positioned over the ceiling.

5. Tighten the dog-ears until ﬁrm contact is made with the ceiling surface.

CAUTION! Do not overtighten the dog-ear screws! Insert the grille's safety tether pin into the supplied hole on the loudspeaker bafﬂe and install the grille.

Dog-ears against loudspeaker

Turn the screw clockwise to engage

the dog-ear with the ceiling.
