LightSpeed Technologies CNXQ 850 - Manual

Step 1: Selecting Speaker Location
One CNXQ™ Flat Panel Ceiling Speaker is designed
for rooms smaller than 1200 sq. ft. and with a ceiling
height of 9–12 feet.
Before starting the system installation, speaker placement
needs to be determined. This speaker is designed to
be mounted in the ceiling in or near the middle of the
classroom (See figure 1.). The speaker lays directly into the
acoustic ceiling grid, so locate the tile that is approximately
in the center of the classroom.
Step 2: Installing and Connecting the Speaker Wire
A. Identify a suitable location for the receiver/amplifier
where it is easily assessable, close to a power outlet,
and at least 6 feet away from any computers.
B. Remove the ceiling tile from the ceiling that was
identified in Step 1.
C. Set the ceiling tile on a flat work surface with patterned
side facing down. The dimensions of the CNXQ Speaker
are 2’ x 2’ Using a straight edge, cut 24” off the
end of a standard 2’ x 4’ ceiling tile as shown in Figure
2. (If the ceiling tile grid is 2’ x 2’, simply remove the
tile and replace with the CNXQ speaker).
D. Locate the coil of speaker wire. To connect the wire to
the speaker, press down on the colored terminals on
the back of the speaker, insert the wire and release
the tab to clamp it in place. Insert the black wire into
the black-tabbed terminal and the red wire into the
red-tabbed terminal.
E. Place the other end of the wire up through the opening
in the ceiling and route over the ceiling tiles and back
down the wall to the receiver/amplifier. (NOTE: when
routing wire overhead, it is important to always follow
local building and electrical codes, securing wire as
required). Do not connect the wires to the receiver
amplifier yet.
F. If installing the speaker into a 2’ x 4’ suspended
ceiling, snap the included cross tee into the suspended
ceiling grid. Locate the slots in the grid at the center of
the 2’ x 4’ area. Insert one end of the tee, then the
other so it locks into place.
G. The speaker has an earthquake strap connected to the
back so it can be tied off to the ceiling structure for
safety purposes. Unscrew one end of the wire from the
back of the speaker to be tied off to the ceiling
supports. If local building codes do not require the use
of an earthquake strap and it is not being used, you
should completely remove the strap from the speaker
so that does not create unwanted vibration.
H. Lay the CNXQ directly onto the ceiling tile grid as
shown in Figure 3. Secure the speaker to the ceiling
with the earthquake strap as required by local building
codes. Speaker wire should also be secured to the
ceiling. DO NOT lay the speaker wire across the back
of the speaker to avoid unwanted vibration.
I. Insert the cut tile back into the ceiling.
