Installation and Use Manual

Product Description
Thank you for choosing Bogen’s High-Fidelity Ceiling Loudspeakers. Please familiar-
ize 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 instal-
lations.
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.

Installation
The HFCS1and 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.
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.

IMPORTANT
• The HFCS1requires 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.

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
Keep the same polarity terminals wired together to ensure correct speaker polari-
ty. In order to provide the best possible sound, all speakers in a system need to be
pushing out and pulling in at the same time. Therefore all must be wired with the
same polarity.
If the connections to one speaker in a system are reversed from the others, that
speaker’s movement will be out of polarity with the other speakers.This results 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. It is important that all 4 terminal cover screws be
installed in this application.A Bogen Model CK10 cable will accomplish this.

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-ohm 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.
Speaker Grille Installation & Removal
Installation
The speaker grille fits tightly! Push the speaker grille
in until it can go no further. Then, slap around the
edge of the grille to seat the grille.The grille is prop-
erly seated when it is flush with the edge of the bezel.
Removal
Insert a pocketknife blade between the grille and the
bezel about 1/4" deep and then gently pry the grille
upwards. Do this in multiple places around the
circumference of the grille to free the grille.
