The amplified speaker can be mounted on any relatively flat surface. Conduit
connections can be made to the two 1/2" threaded openings at bottom of the housing. A
1/2" conduit plug is supplied for field installation if one of the 1/2" threaded openings
is not utilized. After the mounting location and mounting method have been selected,
proceed with the applicable instructions below.
Property damage, serious injury, or death could occur if an accumulation of
water, snow, dust, etc. resides in the speaker projector, severely reducing or
preventing operation of this device. Mount the unit so speaker projector is
pointed horizontally or slightly downward.
Property damage, serious injury, or death could occur if the projector is mis‑
handled during installation or over time. DO NOT rotate the projector more
than 180 degrees or internal speaker wiring may be damaged.
1. Flat Surface Mounting.
a. Remove and retain the two screws that secure cover to housing.
Remove the cover.
Property damage, serious injury, or death could occur if any objects are in
front of the speaker, severely reducing optimum sound distribution. For maxi‑
mum effectiveness, ensure that the front of the speaker is clear of obstruc‑
tions.
b. Select the mounting location and place rear of the housing against
mounting surface.
c. Using the mounting holes (two (2) inside for Models 300GC and
302GC’s housing or four (4) outside for the Models 300GCX and 302GCX’s external
housing bracket) as a template, scribe drill position marks on the mounting surface.
See figure 1 for mounting hole locations and dimensions.
Before drilling holes in any surface, ensure that both sides of surface are clear
of items that could be damaged.
d. Secure the unit to a wooden mounting surface with #10 x 1" wood
screws. If mounting on a metal surface, drill 13/64" diameter holes and secure the unit
with #10 screws, lockwashers and nuts.
e. Route wires through the 1/2" threaded openings into the SelecTone
unit in accordance with National and Local Electrical codes. Wire size depends upon
the operating current and the distance from the power source.
