Installation and Wiring
This manual will serve to assist in wiring and physically mounting C SERIES
loudspeakers. The directions include assistance to those installers using a
complete Community package of loudspeakers and accessories, including
the integral back cans, grilles, tile rails and so forth. We include instructions
for use of optional Community C SERIES retrofit adapters so that Community
C SERIES loudspeakers can be mounted in other manufacturer's cutouts. 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 70V and 100V power 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. Commercial Design integral 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 are only connecting one (dual conductor) cable, you can use
either (+) and (-) terminal. If you're daisy-chaining a cable to the next loudspeaker,
you may 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.
