the use of a p-ring may be inappropriate, such as in a retro-fit
(existing) installation, or when building codes require that
wall devices be enclosed in 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 AB-2D connec-
tions. For wiring runs longer than 80 feet, 14 gauge wire is
recommended. Using speaker wire larger than 14 gauge for
the AB-2D connections is not recommended—the wire may
not fit into the connectors. Never use solid-core, aluminum,
or "Romex" type wire with the AB-2D. 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 deal-
er, building contractor, or local building and inspection
department if unsure about which type of wire is best for
your application.
AB-2D Mounting Location
Convenient mounting locations for the AB-2D are:
●
Near entry-ways or exits
●
Near a desk
●
At your bedside
●
Close to a telephone

"TECH TIP"
Wire size is
expressed by it's
AWG (American
Wire Gauge)
number. The lower
the AWG number,
the larger the wire,
i.e., 12 AWG wire is
physically larger
than 14 AWG.
