Door Chimes
LB-46, LD-49, LA-58, LA-70MA,
& LA-151WM SERIES
Your NuTone Door Chime is designed for three (3) door
operation. It will sound either 8 or 4 notes for the front door,
one (1) note for a second door and a different note for a third
door. Use the NuTone transformer packaged with the chime
for best results.
When installing this chime and wiring has been completed,
check to make sure that the pushbuttons are in good
operating condition. When installed correctly, they must not
stick – meaning they must return to the original position to
open the circuit.

One Electronic Chime with one 2-Note Chime
HELPFUL HINTS – This chime is "protection
packed". Handle carefully as you would any
precision instrument. Comply with local wiring
codes when wiring the chime. Upon
completion of the installation, if the chime does
not operate, recheck your installation with these
instructions and wiring diagram. If the chime
still does not operate, check the pushbutton(s)
for poor contact or loose connections.
INSTALLATION
Select a central location to insure an audible
signal throughout the home. For a large ranchstyle or multi-story home, two chimes may be
needed. Refer to Figures 2 and 3 for Multiple
Chime Wiring Information.
WIRING
NOTE: BE SURE HOUSE POWER IS TURNED OFF WHEN
INSTALLING THE TRANSFORMER.
1. Mount the transformer to a convenient junction box (attic location
is not recommended) or circuit breaker box. Connect the
transformer leads to house power leads: black to black and
white to white.
IMPORTANT: All wiring connections must comply with
national or local codes. Run two conductor, 18 gauge wire from
the transformer and pushbuttons to the chime location. Bring wires
through wiring access hole in the chime baseplate and fasten the
baseplate to the wall with screws provided. Connect wires to
chime terminal board as illustrated in Figure 1. For two chime
installation refer to Figure 2. For one chime with one two-note
chime, refer to Figure 3.

FINAL ADJUSTMENTS
VOLUME ADUSTMENT
Make any necessary adjustments using the volume control.
TUBE INSTALLATION (long tube models).
1. Refer to Figure 4. Hang tubes onto hanger bracket hooks so that the
longest tube is at the left and the shortest at the right. Adjust tube
supports on hanger brackets so plungers strike tubes to produce
proper tone quality.
2. Adjust volume control as desired.
3. IMPORTANT: If the volume control has been set to the maximum
level, the chime may double strike one or more notes. If this should
occur, turn the volume control down to a lower level.
If chime plungers should ever get "sluggish" in their movement, clean
the plungers with a non-flammable cleaning fluid and wipe dry.
CAUTION: NEVER OIL CHIME PLUNGERS.
