Installation and Wiring

INSTALLATION NOTE: CEILING TILE CAUTION

When mounting the units into 2'˘2' or 2'˘4' sus- pended ceiling tiles, DO NOT install them in light- weight fibreglass-type tiles without full secondary 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 speaker MUST be strung taut in these sit- uations and MUST remove most of the force of the speaker on the tile to ensure that the speaker does not deform the tile.

Step 4: Mount the Speaker Into the Ceiling (Figure 9)

Push the speaker into the ceiling hole until the front baffle rim is flush with the ceiling. Tighten the

INSTALLATION NOTE: MOUNTING TABS

For each attachment screw, first turn one half-turn counterclockwise to release the mounting tab from its guide.

Step 5: Connect an Auxiliary Support Line (Figure 11)

Note the support ring on the back of the speaker. The ring allows for connection to a independent and secure anchor point. Construction codes often require the use of this secondary support point.

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 10).

Step 6: Adjust Tap Selector (Figure 12)

The tap selector switch is located on the front baffle. Adjust the speaker to the appropriate tap setting before installing the grille. In some 70V/100V con- stant voltage installations it is advisable to leave the grilles off if final speaker audio level balance adjust- ments are to be made later. After the levels are adjusted the grilles can then be installed.
