NuTone LA-157MA Manual De Usuario

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.

For a single installation, use NuTone Model 515T or 101T Transformer.

For two or more chimes, use NuTone Model 105T or 301T 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.

Refer to Figure 1. Mount the transformer to a convenient junction

box (attic location is not recommended) or circuit breaker box.
Connect house power leads to transformer leads – black to black
and white to white.

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). 

Place the chime over the baseplate. Make sure hanger bracket

engages slot in top of baseplate.

If chime plungers should ever become “sluggish” in their

movement, clean plungers with a nonflammable cleaning fluid and
wipe dry.
CAUTION: NEVER OIL CHIME PLUNGERS.
