Conduit Knockout (x2) 1 HFCS1Rear Drawing (terminal cover) Installation The HFCS1 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 environments. 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 • There must be a minimum of 11" of vertical clearance between the FRONT of the mounting surface and any other structure for the speaker to fit. 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 HFCS1 will be installed. If using a TBCR, then follow its installation instructions for the specific type of environment the HFCS1 is being installed in. 2. Make electrical connections to the pluggable terminal strip and plug it onto the HFCS1. 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. 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 HFCS1. Wiring is terminated at a snap-lock input connector. There are two positive and two negative terminals to accommodate daisychaining of speakers in a system. Daisy-Chaining The HFCS1’s snap-lock input connector allows for easy daisy-chaining of speakers by providing a second terminal of each polarity. See the figures to the right and below for correct wiring for daisy-chaining of terminals. Speaker Phasing Keep the same polarity terminals wired together to ensure correct phasing. In order to provide the best possible sound, all of the speakers in a system need to be pushing out and pulling in at the same time. If the connections to one speaker in a system are reversed from the others, that speaker’s movement will be out of sync with the other speakers.This will result in a loss of low frequency response and will effect the overall performance of the system. Terminal Covers • The two terminal cover halves are attached to the back of the speaker using 4 screws. It is important that all 4 screws be used to mount the covers. • A slot between the two halves allows the wire to exit the speaker while protecting the connections.The cover's eyelets can be used to anchor the wire using a wire tie if desired. • If local codes require the use of a conduit for connections or strain relief of the connections, a knockout can be removed and a proper fitting installed for the particular situation. • Eyelets are provided on the terminal covers to provide a means of securing the speaker to the structure when necessary. It is important that all 4 terminal cover attaching screws be installed in this application. 3 Selecting Power Levels The front-mounted selector switch is used to set the appropriate power level or impedance for your system. Using a small, flat-blade screwdriver, turn the knob until the slot points to the power level you require. 70V/100V Systems Both power setting scales for 70V and 100V systems are labeled on the speakers. On the 100V scale, the last position clockwise is marked with a symbol. Do not use this position in 100V systems. 16. Systems The fully counterclockwise position of the setting switch is the 16-ohm position.This setting is suitable for use with low-impedance amplifiers that typically support 4- or 8-ohm speakers.The speaker’s higher, 16-ohm impedance makes it easier to combine multiple speakers into series-parallel networks while keeping the total system impedance at a level suitable for low-impedance amplifiers.
