Introduction

Congratulations and thank you for your ceiling loudspeaker purchase. The AD-CI52T
and AD-CI52ST models offer excellent acoustic performance in an easy-to-install and
attractive package. Please review these instructions carefully and follow the recom-
mendations. Consult a licensed installation professional if you are uncertain about any
mounting issues.
Both models feature a 5.25” (133mm) low-frequency (LF) driver and a 1”(25mm) dome
high-frequency (HF) driver. The AD-CI52ST features a shallow enclosure which is larger
in diameter and ported. All models are equipped with an audio transformer suitable for
70V and 100V distributed systems, as well as a tap-selector switch which can bypass
the transformer for 8 ohm applications.

What’s Included

Your ceiling loudspeaker box contains: - the loudspeaker cabinet
- the protective grill assembly
- two support brackets for suspended ceiling installations
- C-ring bracket for suspended ceilings and other ceiling reinforcing applications
- Self-tapping screws(M4.2 X 1.4 X 10mm) for securing the C-ring-to-support brackets
- grill clip used for clipping the plastic grill retaining lines together
- two terminal block connectors for connecting signal and daisy-chaining

Installation Options

The AcousticDesign in-ceiling loudspeakers can be mounted in suspended ceilings, as well as non-suspended types. We recommend an
installation professional be consulted for safety assurance, quality installation, and optimum acoustic performance.
For suspended ceiling applications, the suspended ceiling support brackets must be used with the C-ring bracket. The suspended ceiling
support brackets are designed to accommodate 24” or 600 mm t-channel grid spacing. The brackets do not attach to the t-channel; the
angled “V” bend sits over the t-channel and will catch the t-channel in the event of a tile failure or fall-out.
For other ceiling types, the C-ring bracket can be used to reinforce the mounting surface. If the ceiling is suitably strong, the loud-
speaker can be secured in the cutout hole without additional reinforcement.
Audio connections are made using terminal block type connectors. Two sets of terminals are provided; one set for the signal connection
and another for pass-through (or daisy chain) connection to other loudspeakers on the same distribution circuit.
Two safety features are provided, an enclosure-retaining safety tab and a grill-retaining safety tether. The enclosure tab is a metal tab
on top of the enclosure suitable for securing the loudspeaker to building framing; this provides maximum safety in the event the ceiling
structure fails for any reason. The grill’s safety tether prevents the grill from falling in the event it should vibrate loose.

Use the Secondary Support Tab!
Loudspeakers can potentially generate substantial vibra-
tion. In addition to ensuring all hardware is properly
installed and secured, you must use the secondary support
tab on the enclosure to secure the loudspeaker to an appro-
priate structural support. This will minimize the chance of
the loudspeaker falling from the ceiling in the event the pri-
mary mount fails. Any cable or wire used as a secondary
support line must be strong enough to support several times
the weight of the loudspeaker. Do not use rope, string,
twine or other textile-based line in the secondary support
system as it is easily cut or burned. The secondary support
attachment point and any fasteners used on the building’s
structure must also be strong enough to support several
times the weight of the loudspeaker.

Mounting Clamps

The mounting clamps are
part of the assembly for
simple use. Do not install
the grill until clamps have
been tightened and any
adjustments made.
Before inserting the cabi-
net into the mounting cut-
out, make sure the clamps
are folded in against the
cabinet, see 1, right.
After the cabinet is
installed into the mount-
ing cutout, tighten each
clamp’s screw using a #2
Phillips screwdriver, see 2,
right.
The clamp rotates 90° and
is then pulled tight by the
screw, see 3, right.

Grill Safety Clip

The cabinet and the grill both have a small loop of
plastic line. The grill’s loop has a clip attached.
Using the grill clip, attach the grill to the cabinet’s
loop. This will help prevent the grill from falling
should it become detached.
Other Recommendations and Important Information
•Grill removal: The grill can be removed by carefully prying around its outer edge or inserting a small, metal pin or hook into the
grill’s openings and pulling evenly around its perimeter.
•If rattles or buzzing is heard during operation, it may be necessary to put vibration dampening material between the support
rails and the ceiling tiles and/or t-channels.
•The support rails have holes along their usable length to attach the C-ring bracket. This allows for the cutout to be placed in
many positions along the ceiling tile width.

Connections

Connect signal wires to terminal block connector, note
polarity. Connect next loudspeaker to remaining connector.
Connectors are wired in parallel, internal connection is
rated for 400W max.

Installation Procedure

1- Using the included C-ring or the dimensions provided, trace a cutout pattern onto
the ceiling surface.
2- Cut the mounting hole. Use a sharp tool to avoid stressing or cracking the mount-
ing surface.
3- Pull the wires through the hole.
4- Pass the two suspended ceiling support brackets through the hole and place as
shown in the illustration. Make sure the part of the bracket that is flat against the tile
is toward the hole. If installing in a non-suspended ceiling application, these brackets
are not required.
5- Pass the C-ring bracket through the hole. Slide the cutout slot into the hole first,
and then rotate the bracket so it passes through the hole. Be sure the wires pass
through the ring.
6- Position the support brackets, and secure the C-ring bracket to each of the support
brackets using the screws provided. If installing in a non-suspended ceiling applica-
tion, skip this step.
7- Loosen the connection cover plate retaining screw and swing the cover open.
Install an appropriate non-metallic sheathed cable connector into the hole provided
on the cover plate.
8- Temporarily support the enclosure so the wires may be passed through the enclo-
sure top with enough slack to prepare and terminate the wires.
9- Locate the terminal block connectors included with the loudspeaker. Loosen the
wire retaining screws fully.
10- Strip the wire ends approximately 5 mm (0.2”) and insert each wire into its proper
connector position. Tighten the wire retaining screws fully.
11- Rotate the connection cover plate closed, making sure not to stress the connec-
tions or pinch the wires. Tighten the cover plate’s retaining screw.
12- Adjust the wiring at the entry point, if necessary, and tighten the clamping
screw(s) on the non-metallic sheathed cable connector. This prevents wire stress and
strain from pulling the connections/connectors loose.
13- Attach a safety cable (secondary support cable) from the enclosure’s attachment
tab to an appropriate support point. This cable and the attachment points must be
strong enough to support many times the weight of the loudspeaker in the event the
primary mounting system fails.
14- Insert the enclosure into the ceiling cutout, making sure any brackets used
remain properly positioned. Tighten the loudspeaker’s mounting clamp screws.
15- Set the tap selector switch to the desired position. 70V systems, all four posi-
tions may be used. Do not use highest tap setting with 100V systems. 8 ohm sys-
tems, se selector to 8 ohm position.
16- Make sure all tests and adjustments are complete before installing the grills.
Locate the loudspeaker’s grill. The cabinet and the grill both have a small loop of
plastic line. Using the clip on the grill’s line, attach the grill’s safety loop to the cabi-
net’s loop. Carefully work the grill into its retaining slot and press firmly into place.
Work the grill in slowly and evenly to avoid damage. Make sure all tests and adjust-
ments are complete before installing the grills.
