Installation to Wood Joist Ceilings or Wood Stud Walls
NOTE: Wall installation with models EXC, EXC-S and EXC-W is not available.
Use a stud fi nder to locate the edges of the stud or joist. Use of an edge-to-edge stud fi nder is highly
recommended. Based on its edges, draw a vertical line down the stud's or joist’s center. Place ceiling/wall plate
(A) on wall or ceiling as a template, making sure that the two mounting slots are on the centerline.
For ceiling installation: Opening on outer channel (B) indicates front of mount. Use the correct mounting slots
on the ceiling/wall plate depending on ceiling joist orientation as shown in fi gure 2.1 and fi gure 2.2. Mounting slots
on ceiling plate allow for 45° (
± 22.5) of rotation before securing to joist.
For wall installation: Opening on outer channel (B) indicates top of mount.
Mark the center of the two mounting holes. Drill two 5/32" (4 mm) dia. holes 2-1/2" (65 mm) deep. Secure
ceiling/wall plate (A) to wood stud or joist using two #14 x 2-1/2" wood screws (H) and two fl at washers (O)
as shown.

• Installer must verify that the supporting surface will safely support the combined load of the equipment and all
attached hardware and components.
• Tighten wood screws so that ceiling/wall plate is fi rmly attached, but do not overtighten. Overtightening can damage
the screws, greatly reducing their holding power.
• Never tighten in excess of 80 in. • lb (9 N.M.).
• Make sure that mounting screws are anchored into the center of the stud or joist. The use of an "edge to edge" stud
fi nder is highly recommended.
• Hardware provided is for attachment of mount through standard thickness drywall or plaster into wood studs or
joists. Installers are responsible to provide hardware for other types of mounting situations (not UL approved).
