designed and intended to be mounted in a suspended ceiling
grid. Installation of loudspeakers should only be performed by
trained and qualied personnel. All electrical connections must
conform to applicable city, county, state, and national (NEC)
electrical codes.
DANGER: It is possible to experience severe electrical shock
from a power amplier. Always make sure that all power
ampliers are in the "OFF" position and unplugged from an AC
Mains supply before performing electrical work.
IMPORTANT: Please review the safety guide accompanying this
product and these installation instructions prior to installing this

CAUTION: Installation of Biamp loudspeakers should only be
performed by trained and qualied personnel. It is strongly
recommended that a licensed and certied professional
structural engineer approve the mounting. Severe injury and/
or loss of life may occur if this product is improperly installed.
DANGER: It is advised that a safety cable be secured to a
suitable load-bearing point separate from the primary
loudspeaker mounting point, with as little slack as possible so
as not to develop undue kinetic force if the primary mount
were to fail.
IMPORTANT: This loudspeaker is approved for use in plenum
air handling spaces.

INSTALLATION
The DC220T ceiling tile loudspeaker is designed to be installed with or without
above ceiling access in 2' x 2' or 2' x 4' drop ceilings. The DC220T-M is designed
for installation in 600mm x 600mm, or 600mm x 1200mm drop ceilings.
Typical installation in drop (suspended) ceiling
1. Run wires to the loudspeaker locations. Wiring connections can be made
before or after placing the loudspeaker in the ceiling grid. Refer to the
Wiring section for details.
2. Remove the existing ceiling tile and place the tile loudspeaker in the grid.
3. If they haven't already been made, loosen the input cover and make the
wiring connections (see Wiring Section).

NOTE: All electrical installation
connections for loudspeaker
lines are subject to all
applicable governmental building and
re codes. The selection of appropriate
electrical hardware to interface with the
loudspeaker lies solely with the
installation professional. Biamp
recommends that an appropriately
licensed engineer, electrician, or other
professional identify and select the
appropriate conduit, ttings, wire, etc. for
the installation.

Installation in a drop (suspended) ceiling with conduit
Access to the loudspeaker through an adjacent tile space is necessary to attach
the conduit after the unit is installed in the ceiling grid. The input cover has a
knockout on the top allowing 2 sizes of conduit: 1/2" NPT, 3/4" NPT (22mm [.875"],
29mm [1.14"]). Conduit fittings are not included. Use flexible conduit close to the
loudspeaker to make alignment and connections easier.
NOTE: Conduit use may be required for some plenum spaces and should also
be used in damp spaces. Using the cover with conduit wiring will comply with the
City of Chicago requirements.

INSTALLATION (continued)
Wiring
The input cover acts as a strain relief for wiring connections. Connections should
be kept inside the input recess. The cover has knockouts to accept 1/2" and
3/4" NPT (22 mm [0.875"], 29mm [1.14"]) conduit ttings.
4. Loosen the screws holding the input cover (circled).
5. Move the cover up to clear the lower screws and rotate it around to expose
the recessed area and the cable.
6. Make the connections secure with wirenuts or other connectors. Follow any
applicable local electrical rules or codes.
7. Rotate the cover back on and secure with the 3 screws. The exiting
cable(s) can be routed between the cover and the foam on the side of the
input area (shown), or with conduit applications, by using a conduit fitting or
cable clamp in the knockout and routing the wiring through it.

PAINTING INSTRUCTIONS
The grille may be painted to match room decor. Do NOT
paint the grille when on the loudspeaker. The loudspeaker
should be removed from the ceiling grid to access the grill
screws.
1. Unscrew the grille from the face (2 per side). Carefully
remove the grille from the face, do not bend the grille.
2. Thoroughly clean and degrease the grille before
painting. Do not use a solvent (see Cautions at right).
3. Paint the grille with several light coats of spray paint
at twice the recommended distance from the grille. Do
not clog the grille perforations with paint.
4. Allow the paint to fully dry and cure.
5. Fit the grille back on the loudspeaker face, and
reinstall the screws to secure it.
CAUTION: NEVER use abrasives, gasoline,
kerosene, acetone, methyl ethyl ketone (MEK),
paint thinner, harsh detergents or other chemicals on
the loudspeaker. These chemicals and agents may
permanently damage the nish. Some are also toxic
and highly ammable.
IMPORTANT: Do not bend or damage the grille on
removal or reinstallation.
IMPORTANT: Blocking the grille holes with paint or
getting any paint on the drivers or internal parts will
aect loudspeaker performance and void the warranty.
