Installation Preparations

The entire installation can be accomplished, if necessary, without requiring access above the ceiling. Bracketry for use with either suspended ceilings or sheetrock ceilings is included. The speaker is held securely in place via mounting ears which lock into place.

OPTIONAL PRE-INSTALLATION BRACKETS

IN MOST CASES, NO BRACKETS OTHER THAN THE ONES INCLUDED WITH YOUR SPEAKER ARE REQUIRED. Everything needed for most installations of these loudspeakers is provided with your Control Contractor ceiling speaker.

However, sometimes a pre-installation bracket is required to reserve the space within the ceiling area, or to provide a place to which wiring can be tied behind the sheet rock. A pre-installation bracket can also function as a cutout template when many cutouts are to be made. Two types of pre-installation brackets are available from JBL Professional as optional accessories:

1)The optional NEW-CONSTRUCTION BRACKET is made of flat sheet metal, with wings to attach to the building structure. Holes are drilled for nails or screws at

16 inches (406 mm) and 24 inches (610 mm) on-center. Additional holes can be drilled by the installer at other spacings up to a maximum of 24 ¾ inches (630 mm) apart. Sheet rock installs over the bracket, and the bracket provides a template for blind cutout of the hole in the sheet rock. The sheet rock can typically be cut with a router- type cutting tool, using the bracket ring as a cutout guide.
