3.4 Optional SP2000A Speaker/Microphone Installation
The installation described below is for typical mounting of the SP2000A directly against the
inside of the speaker grill. If it needs to be mounted at an angle, or at a distance from the
speaker grill, its base can be bolted to a horizontal surface. Installation of this speaker is
not recommended, except for half duplex systems.
Installation:
 Drill four inch (3.2 mm) pilot holes at the
spots shown on Figure 22 A, in the flange of
the SP2000A.
 Find the enclosed SP2000A mounting template.
Hold the template centered against the outside
of the speaker grill on the speaker post or
menu board. With a pencil or other sharp
object, mark the speaker grill through the four
drill-hole targets on the template. Drill a
3
/
16
inch (4.8 mm) hole at each of the marked spots.
 Hold the SP2000A flush against the inside of
the speaker grill, with the four pilot holes on
its flange directly over the four holes drilled
through the grill speaker. From the outside of
the speaker grill, drill the four enclosed self-
tapping screws through the drilled holes in the
speaker grill and through the SP2000A flange
at each pilot hole, as shown in Figure 22 B.
Cable Connections:
CAUTION: Never run high-voltage cables in the same conduit with audio or
loop cables.
 Connect the red wire from the appropriate cable to the white SP2000A wire, and the
black cable wire to the black SP2000A wire as shown in Figure 23. Do not connect
the drain wire.
 Solder the connection and cover it with electrical tape. Solder all splices.
