JBL CONTROL 24СT MICRO [5/16] Installation preparations

Installation Preparations

OPTIONAL PRE-INSTALLATION BRACKETS

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.

YOUR SPEAKER ARE REQ

UIRED. 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.
