Installation

The HFCS1 and HFCS1LP can be installed in a variety of ceiling environments. The use of the TBCR (Tile Bridge Support Ring) accessory may be desired for many of these.

For suspended ceilings, the use of a TBCR is strongly recommended to help support and distribute the weight of the speaker.

In new construction installations the TBCR, installed before sheetrock, acts as a routing template that ensures an accurate and neat hole for installation. The TBCR can also be used as a support ring in retrofit applications to better distribute the speaker’s clamping forces.

IMPORTANT

•The HFCS1 requires a minimum of 11" of vertical clearance between the FRONT of the mounting surface and any other structure for the speaker to fit.The HFCS1LP requires a minimum of 6-¾" of vertical clearance.

•Before cutting the full hole, use a smaller exploratory hole to determine if there are any obstructions.

•The edge of the hole must be a minimum of 1-¼" away from any side obstruc- tions to ensure that they will not interfere with the action of the clamps.

1. Begin by cutting a 10-¾" circular hole where the speaker will be installed. If using a TBCR, then follow its installation instructions for the specific type of envi- ronment the speaker is being installed in.

2.Make electrical connections to the pluggable terminal strip and plug it onto the speaker. See Speaker Wiring section.

3.Install terminal cover plates, if necessary or desired, using 4 screws. See the Terminal Covers section if using conduit or if it is required to secure the speaker directly to the structure (typically for suspended ceilings).

4.Remove the speaker’s grille (if neccessary). See Speaker Grille Installation & Removal section.

5.Set the power level using the rotary selector switch on the front panel. Refer to the Selecting Power Levels section for instructions on selecting the power level.

6.Position the swing-out clamps so that they are against the body of the speaker and insert the speaker into its opening in the ceiling.

7.Tighten the clamps by turning the clamping screws clockwise. Do not over-tighten the clamps - only tighten until the speaker is fairly snug in the mounting hole. If using an electric driver, set the clutch on the driver to the lowest setting.

8.(Re)install the speaker’s grille. See Speaker Grille Installation & Removal section.
