The SCW-1D is a Decora- style module designed to use “Decora-style” face- plates and mounting hard- ware. Decora faceplates (up to 6-gang) with color- matched plate screws are available from your Niles dealer.
SCW-1D
Mounting Locations
Convenient mounting loca- tions for the SCW-1D are:
•Near entryways or exits
•Near a desk
•At your bedside
•Close to a telephone
•Near other wall controls
P-Ring and Electrical
Boxes
The mounting depth of the SCW-1D is 2-3/8”. When installed, the unit extends 1-7/8” behind the sheet- rock wall (assuming 1/2” sheetrock). For installation, you must choose between a standard light switch plaster ring (p-ring) or a standard 18 cubic inch (or larger) electrical box. Suitable p- rings and electrical boxes are available from your Niles
electrical boxes. Contact your local building code and inspection department if unsure.
Type of Speaker Wire
For most applications, we recommend you use 16 or 18 gauge, stranded copper speaker wire for the SCW-1D and connections. For wiring runs longer than 80 feet, 14 gauge wire is recommend- ed. Using speaker wire larger than 14 gauge for SCW-1D and connections is not rec- ommended — the wire may not fit into the connectors. Never use solid-core, alu- minum or “Romex” type wire with the SCW-1D. When running speaker wires inside walls, most states and municipalities in the U.S. specify that you must use a special type of speaker wire. Usually, the requirement is that the wire has a specific “CL” fire rating, such as “CL-2” or “CL-3”. Consult your Niles dealer, building contractor, or local building and inspection department if unsure about which type of wire is best for your application.
devices. We do not recom- mend this. Speaker wires can act as an “antenna” for electrical noise. Locating speaker wires too close to a light switch or dimmer may cause a “popping” or “buzzing” sound to be heard through the speak- ers. If you must locate an SCW-1D near electrical devices, install it in a sepa- rate metal electrical box, ground the box to the elec- trical system ground, and route the speaker wires sev- eral feet away from the electrical wiring.

If you are installing the SCW-1D into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood and metal studs; electrical, tele- phone wire or other types of wiring; plumbing; con- duit; old wall safes; etc.
1.Install the electrical box or p-ring in the usual manner.
2.Run all the necessary wiring to the SCW-1D. Label the wires for future reference.
3.Make the connections to the SCW-1D. Strip 1/4” of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends. Insert each wire into the appropri- ate hole on the connector blocks; secure the wiring to the connectors by tighten- ing the small connector screws. Be certain that proper phasing is obser- ved — connect the positive
terminals on the SCW-1D to the positive terminals on the amplifier and speakers; the negative terminals on the SCW-1D to the negative terminals on the amplifier and speakers. See Figure 1.
4.Secure the SCW-1D to the electrical box or p-ring. Insert the 1-1/4” long device screws into the oblong- shaped screw holes on the top and bottom of the SCW-1D. Note that the oblong shape of the screw holes allow you to position the SCW-1D so that it is ver- tical. Position the SCW-1D so that the screws are aligned with the threaded holes in the electrical box or p-ring. Tighten the screws using a philips screwdriver. DO NOT OVER-TIGHTEN. In some instances, you may need to loosen these screws several turns to allow the SCW-1D to fit flush with the Decora cover plate.
5.Use the shorter plate screws to fasten the Decora faceplate to the SCW-1D.
DO NOT OVER-TIGHTEN THE PLATE SCREWS OR YOU MAY DAMAGE THE FACEPLATE. Line up all the screws in the same direction for a finished look. NOTE: Certain “old work” or “retro-fit” boxes, such as the Carlon B225R, have a plastic “lip” which interferes with the Decora faceplate screws. This lip prevents you from being able to tighten the screws com- pletely. To make the clear- ance necessary for these screws, you must remove the parts of the lip causing interference. There are two ways to accomplish this:
1.Drill through the lip of the box at the screw points.
2.Cut notches into the lip with a pair of diagonal cutters.

dealer or a local electrical supply company. Using the p-ring is best because it gives you unobstructed access to the full depth of the wall. In some instances, the use of a p-ring may be inappropriate, such as in a retro-fit (existing construc- tion) installation, or when building codes require that wall devices be enclosed in
