Step 5

Make sure the RotoLock clamps are in the full clockwise position so that all the clamps are tucked within the cutout border. Insert the speaker into the hole in the ceiling.

Note: The maximum clamp thickness is 1-1/4" (32mm)

SAFETY PRECAUTION

Attaching the seismic tab to a support line is highly

recommended for additional safety

Step 6

Tighten the four screws on the front of the baffle. The RotoLock clamps will rotate into position automatically and begin clamping. When you notice resistance on the four screws, the speaker has been clamped successfully.

The flange is designed to flex and conform to any small imperfections in the ceiling surface. The screws should not be tightened so far that the flange bows out.

Step 7

At this step in the installation the transformer tap selector can be set. Depending on your installation you may wait to set the volume of each speaker until the system is completely installed.

After the speaker is installed, and transformer tap adjustments are made, the grille can be installed. Insert about half of the grille into the groove at the edge of the speaker. Gently fit the remaining half of the grill into the speaker by working your hands around the speaker fitting the grille into the groove as you go along.

Note: The torque applied to the mounting screws can be adjusted for proper grille fit.

The included C-bracket and tile support rails should be used in all suspended ceiling installations. The C-bracket and tile support rails can also be used in installations when the speakers are mounted into material that will not support their weight.

Insert the two tile support rails and C-bracket through the hole you have cut. placing them as shown. Using the two screws that are supplied, screw the C-bracket to the tile support rails as shown.

After the C-bracket and tile support rails are installed follow Step 2 through Step 7 in the standard installation instructions.
