LOCATION
REPLACEMENT FOR EXISTING 2-NOTE CHIME
1. Locate the Inside Speaker where existing chime is
located. In many cases existing wiring can be
used - see enclosed "IDENTIFYING CHIME WIRING
INSTRUCTIONS."
2. If existing 2-Note Chime is mounted at a height which is
inconvenient to reach, a pull cord is provided to operate the
Intercom Control button.
3. IMPORTANT: DO NOT LOCATE SPEAKERS MORE THAN
300 FEET APART. DO NOT LOCATE SPEAKERS BACK-
TO-BACK ON THE SAME WALL.
4. Locate Door Speaker where existing pushbutton is located.
Use pushbutton wiring – see enclosed "IDENTIFYING
CHIME WIRING INSTRUCTIONS." Note: If existing
pushbutton is uneven or narrow surface, It will be
necessary to locate Door Speaker elsewhere.
5. Locate Door Speaker: (A) on an even surface; (B) on a
surface wide enough for the speaker; (C) as close to existing
wire as possible.
IMPORTANT: NuTone cannot be responsible for improper
intercom operation that results from interference generated
by light dimmers, fluorescent lighting fixtures, and similar
electrical products, such interference must be corrected at
the source. As an aid to help reduce this interference, all
remote cables must be placed at least 12 inches from any
A.C. power wiring.
NEW INSTALLATION
1. Locate the Inside Speaker wherever it is convenient. Install
speaker at an easy operating height.
2. Locate Door Speaker close to the door. Install speaker at
height for easy pushbutton operation.
3. Try to locate speaker where running the wiring will not present
a problem.

WIRING CAUTIONS
