WIRING
WIRING/CONDUIT NOTES
Most commercial ceiling installations permit the use of Class 2
wire for wiring loudspeakers. Installation of a loudspeaker in a
plenum ceiling may require CL2P wire, and when wire is routed
through vertical air handling ducts or passes from fl oor to fl oor
it may require CL2R wire. As well, to maintain compliance with
plenum installations, it may be required to use metallic electri-
cal connectors and metallic conduit or tubing. Always consult
the Authorities having jurisdiction (AHJ) over the installation,
and refer to the National Electrical Code (NEC) – NFPA 70 for
determining acceptable wiring and termination methods.
WIRING THE LOUDSPEAKER
1. Remove the speakers from the packaging, open the
terminal cover plate door and remove the green input
connector from the speaker. (see
Figure 8
).
2.
Strip approximately 3/16” of the insulation from each of the
amplifi er’s speaker leads. Insert the leads into the correct
square openings on the input connector according to the
chart in
Figure 9
.
NOTE: When using multiple speakers you can
connect the speakers either in parallel or in the
‘loop-thru’ method (see
Figure 10
).
3. Use a small flat-head screwdriver to tighten the
corresponding screws to secure the wires in the connector
(see
Figure 11
).
4. Once all the speaker wires are terminated plug the green
input connectors into the speakers.
• Route the wires through the Strain Relief Fitting on the
back of the speaker (see
Figure 12
). Tighten the screws
on the fi tting to clamp the wires. Make sure not to over-
tighten the screws and damage the wire.
NOTE: The maximum clamp thickness for the Strain Relief
Fitting is 1¼” (32mm).
