Specifications subject to change without notice. 54-2091-01C0610 Product Description Thank you for choosing Bogen’s High-Fidelity Ceiling Loudspeakers. Please familiarize yourself with the product by reading and reviewing the descriptions and diagrams in this manual. Bogen’s coaxial 2-way hi-fi ceiling speakers deliver unsurpassed performance and value. The HFCS1(LP)’s steel back can and front exit venting allow for deep bass response, enhancing the quality and intelligibility of both speech and music. The HFCS1LP uses a smaller,low-profile back can that allows for a greater range of installations. Both speakers can be installed either in suspended ceiling structures or hard surfaces (such as sheetrock).They come ready to install with integral swinging arm clamps. An optional mounting bracket (TBCR) is available for additional support (recommended for all suspended ceiling applications).The bracket can also be used for new construction ceilings, providing a cutout guide behind the sheetrock surface and as a C-ring to stiffen the edges of the cutout opening. A variety of speaker power levels are easily selected via a front panel rotary switch. Settings for both 70V and 100V high-impedance systems, as well as a low-impedance (16-ohm) position, are provided. The HFCS1(LP) features a removable snap-lock input connector, providing easy wire connection for input as well as loop-through to the next speaker. IMPORTANT The HFCS1 and HFCS1LP are not outdoor speakers. Do not expose the speakers to rain or moisture.The HFCS1 and HFCS1LP should only be installed by qualified personnel.

Conduit Knockout (x2) 1 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-." 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-." away from any side obstructions to ensure that they will not interfere with the action of the clamps. 1. Begin by cutting a 10-." circular hole where the speaker will be installed. If using a TBCR, then follow its installation instructions for the specific type of environment 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. 2 Speaker Wiring All wiring should be done prior to installation and then plugged into the rear of the speaker. Wiring is terminated at a snap-lock input con- nector. There are two positive and two nega- tive terminals to accommodate daisy-chaining of speakers in a system. Daisy-Chaining The snap-lock input connector allows for easy daisy-chaining of speakers by providing a sec- ond terminal of each polarity. See the figures to the right and below for correct wiring for daisy-chaining of terminals. Speaker Polarity...
