Prepare Ceiling
Refer to
Figure 1.
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 V-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 V-rails as support. Make sure the
clips on the C-ring are properly fi tted over the V-rail.
4. Use sheet-metal screws (5) to secure the C-ring to the V-rails.
Wire the Loudspeakers
Refer to
Figure 2.
1. Pass the wires down through the conduit/stress-relief clamp. Leave enough wire for
making connections. Carefully tighten the clamp over the wires, or over the conduit if
it is used.
2. Wire the female Euro-style plug (1) as shown in
Figure 3
.
3. Plug the connector securely into the receptacle.
4. Slide the cover (4) over the connector and secure with the Phillips screw.
Seismic Safety
Refer to
Figure 4
.
1. Attach an appropriate safety line to the safety tab on the back of the connector cover,
and to an appropriate part of the structure.
WARNING!:
Be sure to check and adhere to local building codes for
seismic requirements. If in doubt, consult an appropriate engineer.
Mount the Loudspeaker
Refer to
Figure 5
.
1. Make sure all of the dog-ears are up against the side of the metal loudspeaker housing.
2. Slide the Loudspeaker Housing up through the hole into the ceiling.
3. Use a Phillips screwdriver to tighten each of the four dog-ear screws. As you tighten the
screws, the dog-ears swing away from the housing and over the ceiling. Be sure all dog-
ears are properly positioned over the ceiling.
CAUTION!:
Do not overtighten the dog-ear screws!
4. Use a fl at-tip screwdriver to set the transformer tap based on the requirements of the
installation.
5. Install the loudspeaker grill.
