Installation Overview
To install and set up an SCP control pad, follow these steps:
1 Turn the equipment off. Make sure that the SCP and the
system switcher are disconnected from the power source.
2 Run cables through the wall or furniture where the SCP
will be installed.
3 Prepare the site and install and ground the electrical box
(if one will be used) or mounting brackets.
4 Set the identification DIP switches on the circuit board.
5 Wire the 5-pole captive screw connectors on both ends of
the cable that was installed in the wall or furniture in step
2 .
6 Plug the wired connectors into the receptacles on the back
of the SCP and on the rear panel of the system switcher.
7 Restore power to the system switcher.
8 Press an input selection button or the “Show Me” button.
If the corresponding LED does not light or the switch to
the selected input is not made, disconnect power from the
switcher and verify correct connector wiring at both ends
of the cable.
9 Mount the SCP in the wall box or furniture, and make sure
the faceplate is tied to an earth ground to prevent damage
caused by electrostatic discharge.
10 Reconnect the switcher to the A/C power source.

electrical wall box to allow room for the raised areas
surrounding the knockouts.
1. Cut out the center portion of the template. Cut up to the
dashed line if using an electrical box, or cut up to the
dotted line if an electrical box will not be used.
2. If wall-mounting the SCP, locate a stud to which the wall
box will be attached.
3. Using the provided template, mark and cut out the
opening on the wall/furniture.
4. Insert the wall box (if used) into the wall, and attach the
wall box to the wall stud (2” x 4”) or furniture with nails or
screws, leaving the front
edge flush with the
wall surface, as
shown in
the
following
illustration.
Preparing the Site, Installing the Electrical Box
An electrical box is included with each SCP 200 and SCP 250,
but a different box can be used. The box must be deep enough
to contain both the SCP’s electrical components and the cables.
The electrical box can be attached to wall studs or to furniture,
or the SCP can be mounted in areas of walls or furniture
without studs if using an optional Extron 2-gang mounting
bracket, part #70-086-01, or 3-gang mounting bracket, part
#70-086-01. Bracket installation instructions are included with
the brackets.
Use the full-size template(s) provided in appendix B as a guide
to mark and cut the hole in the wall or furniture through which
the SCP will be installed. The templates include the
recommended 0.1” (0.25cm) clearance on all sides of the
To attach the wall box to wood, use four #8 to #10 wood or
sheet metal screws. A minimum of 1/2 inch (1.3 cm) of
screw threads must penetrate the wood. If the wood is a
2 x 4, such as a wall stud, 10-penny or larger nails can be
used.
To attach the electrical wall box to metal, use four #8 or #10
sheet metal screws (self-tapping) or #8 or #10 machine
bolts with matching nuts.
If mounting brackets will be used instead of studs, follow
the mounting instructions that came with the brackets.
5. Feed the cables through the wall box. Cable clamps
should be used to hold the cables in place for strain relief.
6. Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink.
