Surface-Mounted

Repeating Tone Door Chime

MODEL: LA-20 SERIES

PLANNING

•Your NuTone Door Chime is designed for three-door operation; First Door – repeating signal; Second Door – two-note signal; Third Door – one-note signal.

•If the home is multiple-level or large ranch style, two or more chimes should be used to provide adequate coverage.

WIRING

CAUTION: Be sure house power is turned off when wiring the 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.

1.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.

2.Refer to Figure 2. Label all wires. Run 18-22 gauge

2-conductor wire from transformer and pushbuttons to chime location.

WIRING OPTIONS

This chime sounds three different tones; a repeating tone, a two-note tone, and a one-note tone. The selection of what tones to use at each door is a matter of owner's choice. If you do not want to use the repeating tone, simply do not wire a pushbutton to the terminal marked RPT. Select what tone you want played by each pushbutton, and then wire the chime accordingly.

MOUNTING CHIME BASE PLATE

Refer to Figure 3. Pull wires through hole in base plate. Secure base plate to wall with supplied screws.

MAKING WIRE CONNECTIONS

IMPORTANT: Be sure wires do not touch tone bars or power units after making wiring connections.

Refer to Figure 2. Make wire connections to terminals as shown. Using wire connector, join all common wires. NOTE: Upon completion of installation, if the chime does not operate properly, check the pushbutton(s) for poor contact or loose connections.
