PREPARING FOR INSTALLATION
The CMS491/492 has been designed to be mounted recessed
into a suspended ceiling consisting of 2’ x 2’ ceiling tiles and
secured by a Wire Vice system.
Installation Requirements
NOTE:
Regarding location selection for models CMS491C/
CMS492C: The design of the projector mount plate/ceiling AV
enclosure system does not require pre-measurement of the
mount location other than choosing the tile placement of the
enclosure. If you are pre-measuring for projector mount
location be sure to consider the items below.
• Dimensional offset of the display/projector relative to
column (due to mount and interface).
• For projectors: any recommended dimensions of
projector relative to target (see installation instructions
included with the projector).
SUPPORT CABLE INSTALLATION
Solid Concrete Ceiling Structure
WARNING:
Failure to provide adequate structural
strength for this component can result in serious personal
injury or damage to equipment! It is the installer’s
responsibility to make sure the structure to which this
component is attached can support five times the combined
weight of all equipment. Reinforce the structure as required
before installing the component.
WARNING:
Anchors must be installed into structurally
sound solid concrete with a minimum thickness of 1.75"
(44.5mm) or greater. Installation into hollow concrete block,
mortar, or concrete that exhibits cracking, spalling, or other
defects may result in failure of anchor and serious personal
injury or damage to equipment!
WARNING:
Failure to properly set anchor may result in
failure of anchor and serious personal injury or damage
to equipment!

Drill 1/4" diameter x 1-3/8" deep pilot hole at each marked
cable anchor support location (See Figure 3). Ensure hole
is at least 2-1/2" from nearest concrete edge. Remove
debris from hole.
Tap anchor (K) into each hole to a depth of at least 1"
(25mm) (See Figure 3).

Using claw portion of hammer, set each anchor (K) by
pulling it out of hole approximately 1/4" (6.4mm). (See
Figure 3)
Insert portion of manufactured loop on cable (N)
through hole in anchor (K) (See Figure 3). Insert end
of cable (N) through loop. Repeat for 3 remaining
support locations.

Examine ceiling structure (solid concrete, wood or steel
truss) above kit to be installed to identify four support
cable anchor locations. Each location should be
approximately 15º outside of support holes in kit
assembly. Mark locations with a pencil.
