Community Distributed Design Series Installation and Operation Manual Page 20
Note: This section describes the wiring
connection of the loudspeaker to the can, and
the wiring between the can and loudspeaker.
Installation order will depend upon the facility and
the installer; pre-installation of the cans including
routing the wires to the can location, or cans
and loudspeakers at the same time. There is no
"perfect or preferred" order for installation. This
section describes the general means to wire the
cans and loudspeakers before mounting the can
into the ceiling (or wall).
This manual will serve to assist in wiring and
physically mounting Distributed Design Series
loudspeakers. The directions include assistance
to those installers using a complete Community
package of loudspeakers and accessories,
including the back cans, grilles, and tile rails.
We include instructions for use of optional
Community Distributed Design Series retrot
adapters so that Community Distributed Design
Series loudspeakers can be mounted in other
manufacturer’s cutouts and/or back cans. If
accessory products from a different manufacturer
are used, please refer to the installation manuals
supplied with those products.
Power Determination
As detailed subsequently, there is no need
to specially select different wire terminals for
8-ohms or for various 70-volt and 100-volt power
Wiring
taps. Instead, a face-mounted tap switch allows
you to make this selection. Once the loudspeaker
is mounted correctly in the ceiling, set the tap
switch to the appropriate tap setting before any
audio is passed through the loudspeaker. Do not
change the setting on the tap switch while the
loudspeaker is in use.
Installation in back cans without conduit
The only tool required is a screwdriver, which is
provided in the Loudspeaker package. Distributed
Design back cans include a swivel-out terminal
access cover that also serves as a cable clamp
when tightened in place. The terminal block in the
can’s outer recess has two (+) connections and
two (-) connections. If you’re only connecting one
(dual conductor) cable, you can use either (+) and
(-) terminal, as illustrated in Figure 20. If you’re
daisy-chaining a cable to the next can, you can
connect the next cable to the remaining (+) and (-)
terminals. There is no need to connect jumpers
or try to stuff two wires into one terminal block
port because each pair of (+) and each pair of (-)
terminals is directly jumpered together on the input
connector as well as internally on the PC board.
Due to this internal jumper on the connector, the
parallel connection will be maintained even if
the input connector comes unplugged from the
loudspeaker’s PC board. See Figure 21.
