TWO-NOTE
SURFACE-MOUNTED
DOOR CHIMES
PLANNING
• Your NuTone Door Chime is designed for two-door operation.
• If the home is multiple-level or large ranch style, two or more
chimes should be used to provide adequate coverage.
• Handle the door chime carefully, as you would any precision
instrument.
WIRING
BE SURE HOUSE POWER IS TURNED OFF WHEN
WIRING THE TRANSFORMER. WIRING CONNECTIONS
MUST COMPLY WITH LOCAL OR NATIONAL WIRING
CODES.
• For a single installation, use NuTone Model C905 or C915
Transformer.
• For two or more chimes, use NuTone Model C907 or C909
Transformer.
NOTE: When fastening chime wiring to wall studs and
ceiling joists, care must be taken to avoid possible “shorts” that
might be created by allowing staples or clips to cut through the
protective wiring insulation.
Mount the transformer to a
convenient junction box (attic
location is not recommended) or
circuit breaker box. Connect house
power leads to transformer leads.
Refer to Figure 1 for single
chime installation or to Figure 2
for multiple chime installation.
Run 2 conductor 18-22 gauge wire from transformer and the
pushbutton(s) to chime location(s). Bring the wires through the
wiring hole in the chime baseplate(s) and fasten the
baseplate(s) to the wall though the mounting holes with the
screws provided. Connect the transformer and the pushbutton
wires to the chime terminal board(s).
NOTE: Upon completion of installation, if the chime
does not operate properly, check the pushbutton(s) for
poor contact or loose connections. Be certain wires are
not touching the tone bars.
TUBE INSTALLATION
(When applicable)
Refer to Figure 3. Hang tubes onto hanger bracket hooks so
that the longest tube is at the left and the shortest at the right.
MOUNTING COVER
Install the chime cover over the baseplate.
