In the cases of bare wire and plenum cable,
it is often possible to provide acceptable
strain relief force by simply tightening the
strain relief screws onto the terminal cover
plate. Reinsert the horizontal screw that
was previously removed, and tighten the
two horizontal screws, clamping the wire
securely between them.
2. If the installation used flexible (BX) or rigid
conduit, the supplied fitting accommodates
up to 3/8-inch (9.5 mm) diameter material.
Slide the wiring through the fitting and in-
sert the conduit into the strain relief (Figure
13). Then tighten the two horizontal screws
that clamp the fitting together, clamping the
conduit securely between them.
After all wiring to the speaker has been com-
pleted, close the hinged terminal cover and
tighten the hold-down screw (see Figure 11).
INSTALLATION NOTE: ALTERNATE
CONDUIT FITTINGS
In some cases, alternate fittings are required,
such as for larger-diameter conduit or to meet
specific code requirements. The fitting provid-
ed can be replaced with a number of standard
fittings available through most electrical sup-
pliers. Simply remove the existing fitting by
unscrewing the two hold-down screws, expos-
ing a 7/8-inch (22 mm) knockout hole. Then
install the alternate fitting. Make sure to always
use the proper fitting in accordance with your
area’s building codes and regulations.
Step 5: Mount the Speaker Into
the Ceiling (Figure 14)
Push the speaker into the ceiling through the
hole until the front baffle rim is flush with the
ceiling. Tighten the mounting tabs by turning
the screw clockwise until the speaker is secure.
Please note that the first clockwise quarter-
turn rotates the attachment tabs outward. The
remaining turns tighten the tabs down onto
the back of the ceiling surface (see Figure 15).
