4 Installation and Wiring
The EVID mounting system has been designed so that, if necessary, the installation can be
done from beneath the ceiling. In some cases with a suspended ceiling grid, however, it may
be easier to access from both the top and bottom of the ceiling tile during the installation
process. Typical installation hardware needed for either suspended ceilings or sheetrock
ceilings is included. The ceiling speaker assembly is held in place by mounting tabs that
securely grip the ceiling material. Input wiring is attached to a removable terminal block
connector that can be prewired if necessary before speaker installation to speed up the
installation process.
INSTALLATION NOTE: USE OF OPTIONAL ROUGH-IN ACCESSORIES
For most installations, no additional hardware is needed. However, a two-step installation
procedure that is sometimes used for installation into sheetrock ceilings can be made easier
by the use of the optional RR and RPK series of rough-in accessories before the ceiling
material is installed. The rough-in accessories provide a cutout guide when many holes are to
be made in a production-line style installation and to ensure the speakers are positioned
correctly as the holes are cut in the sheetrock. Depending on the requirements, two types of
rough-in accessories are available.
RR Series Mounting Plates
RR series plates are made of flat sheet metal with holes to attach to the joists or trusses of a
building structure. The holes are drilled for nails or screws at 16 inches (406 mm), 20 inches
(508 mm) and 24 inches (610 mm) on-center. The installer can drill other holes as needed up
to a maximum of 24-3/4 inches (630 mm) apart. The sheetrock installs over the plate and the
plate provides a template for a blind cutout of the hole in the sheet rock. The ceiling material
is generally cut with a router-type cutting tool, using the plate ring as a cutout guide.

RPK Series Kits
The RPK series rough-in kit contains a RR series plate with a standard 2 gang electrical box
mounted on the top with an attached short length of flexible conduit which connects to the
ceiling speaker conduit clamp on the speaker’s rear terminal cover. This accessory allows for
rigid conduit to be run to the box on the rough-in plate before the speaker or any sheetrock is
installed. After the sheetrock is installed the speaker can be wired up and mounted all from
below the ceiling.
