Installation and Wiring

through the strain relief fitting on the terminal cover plate (Figure 14). Hold the strain relief fit- tings tight around the cable.Tighten the strain relief screws first,then the horizontal screw. In the cases of insulated speaker 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.

2. If the installation used flexible (BX) or rigid

(EMT) conduit, an alternate conduit fitting can be used. See Installation Note and Figure 15 below.

INSTALLATION NOTE: ALTERNATE CONDUIT FITTINGS

Some cases require alternate fittings, many of which are 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 a listed fitting in accordance with your area’s building codes and regulations.

INSTALLATION NOTE: CEILING TILE CAUTION

When mounting the units into 2'˘2' or 2'˘4' sus- pended ceiling tiles, DO NOT install them in lightweight fibreglass-type tiles without full sec- ondary support for the speaker as noted in Step

6.Such tiles are not designed to support any substantial weight. Speaker installation without secondary support will cause the tile to sag and distort, even with the tile bridge installed.The secondary support line at the rear of the speak- er MUST be strung taut in these situations and MUST remove most of the force of the speaker on the tile to ensure that the speaker does not deform the tile.

Step 5: Mount the Speaker Into the Ceiling (Figure 16)

Push the speaker into the ceiling 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 attach-

 

 

ment tabs outward.The

 

 

remaining turns tighten

 

 

the tabs down onto the

 

 

back of the ceiling sur-
