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.

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.
