Step 1: Cut the Hole (Figure 6)
For suspended tile or sheetrock ceilings, cut
out the hole either by tracing the cardboard
template or with a circular cutter set to the
appropriate cutout size. If the wire has been
pre-installed, pull the wiring through the
cutout hole.
Step 2: Install C-Ring and/or Tile
Rails (Figure 7)
All EVID speakers come packaged with two
types of backing hardware: a C-ring and two
tile rails.
For suspended ceiling installations, insert
the C-ring through the hole cut in the ceiling
tile. Place the C-ring around the hole with
the tabs located as shown in Figure 7. Insert
the tile rails through the cut hole in the ceil-
ing tile. Snap the two rails into the two tabs
in the C-ring and align the rails so that the
ends extend OVER the T-channel grid on the
side of the tile. Secure the rails onto the C-
ring tabs by inserting a screw though each
tab into the rail, as shown in Figure 7.
INSTALLATION NOTE: TILE RAILS AND
C-RING
Each speaker comes with two tile rails which
are designed to fit either standard 24-inch-
wide or 600-mm-wide tiles. It is important to
note that the tile rail pieces do not actually
attach to the T-grid struts. The ends of the
rails sit OVER the T-grid strut. Normally, the
tile supports the rails. The tile rails are pre-
punched at regular intervals with holes along
their length. This allows the C-ring to be posi-
tioned at any point along the rail. If the tile
comes out or falls apart, the ends of the sup-
port rails fall onto the T-grid, which prevents
the speaker assembly from falling.
Always use all included support hardware
when installing into suspended ceiling tiles
to make sure the installation is secure.
For sheetrock ceiling installations, the C-
ring should be used by itself to reinforce the
ceiling material and to spread out the pres-
sure from the speaker hold-down tabs.
Guide the C-ring through the cut hole in the
ceiling, and place it on the back side of the
hole before inserting the speaker.
Step 3: Attach Wiring to the
Terminal Connector (Figure 8)
Insert the bare end of wire into the appro-
priate connector terminals as described
below and screw down the hold-down
screw until tight, using a small screwdriver.
