Door Chime
LA-70MA
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.
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
ranch-style 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

1. Mount the transformer to a convenient junction box (attic

transformer and pushbuttons to the chime location. Bring wires

terminal board as illustrated in Figure 1. For two-chime installation,
