Zenith models 122C, 121AC, or 125C).

• Mount door chime in a central location so it can be heard throughout the home (for new installa­tions).

• See actual unit for orientation of base (see Figure 1).

• Always use mounting wall anchors.

• Use all mounting holes located at four corners of base.

• Route the wires through the wire entrance hole (see Figure 1).

WARNING: Turn power off at fuse or circuit breaker before installing transformer.
Follow all national and local codes.

1. Mount Transformer: Transformers should be mounted on or near a junction box. They can

or basements are preferred. Avoid attic locations.

2. Install 16 Volt, 10 Watt transformer according to the instructions supplied with transformer.

3. Run two No. 20 AWG or better bell wires (Heath®/Zenith No. 196C or No. 199C accessory

wire) to the chime location. Strip away 1/2" of insulation from end of wires. Connect each wire
to transformer (see Figure 2).

4. Label Transformer Wires: Using masking tape or wire tags provided on packaging, label one

wire “T” and the other “C”.

5. Mount push button(s) to door frame(s). Run two No. 20 AWG bell wires from push button(s) to

the chime location. Strip away 1/2" of insulation from end of wires. Connect each wire to push
button(s) (see Figure 2).
Label Front Push Button Wires: Using masking tape or wire tags provided on packaging,
label one wire “F” and the other “C”.
Label Rear Push Button Wires: Using masking tape or wire tags provided on packaging,
label one wire “R” and the other “C”.

6. At the chime, pull all wires through wall cavity and out through a 1/2" hole in the wall board.

Route wires through wire entrance hole.

7. Mount chime base to wall using screws provided.

8. Strip away 1/2" of insulation from end of wires. Connect wire “F” to the screw terminal marked

“FRONT”. Connect wire “T” to screw terminal marked “TRANS”. Connect wire “R” to screw
terminal marked “REAR” (see Figure 2).

9. Twist together the wires labeled “C” and secure them with a UL approved wire nut.

10.Place chime cover securely over base (see Figure 5).

11. Restore power. Press push button(s) to test chime.

tion for more information.

2. Check transformer power rating. This chime requires a 16 Volt, 10 Watt transformer.

3. Remove cover from existing chime. Use masking tape or wire tags (provided on packaging) to

label all wires (“F”-Front Push Button, “T”-Transformer, “R”-Rear Push Button). Disconnect la­beled wires from terminals.

4. Remove existing chime base from wall.

5. Route wires through wire entrance hole(s) in new chime base.

6. Mount chime base to wall using screws provided.

7. Connect wire “F” to the screw terminal marked “FRONT”. Connect wire “T” to screw terminal

marked “TRANS”. Connect wire “R” to screw terminal marked “REAR” (see Figure 2).

8. Place chime cover securely over base (see Figure 5).

9. Restore power. Press push button(s) to test chime.

Note:

DIODE INSTALLATION INSTRUCTIONS

Installing Diode: A small electrical component called
a “diode” is supplied with the chime. This diode must
be installed on the terminal screws of the front door
push button (see Figure 4). Without this diode the chime

will not complete the entire tune selected. If, with the di­ode in place, the chime does not play the complete tune
selected, see

REPLACEMENT INSTALLATION WIRING

Troubleshooting

For increased volume from chime, a 16 Volt, 15 Watt transformer is recommended.

• Electrical work must be in accordance with national and local electrical codes. If in doubt,
consult a qualified electrician. Turn power off at fuse or circuit breaker before installing/
replacing transformer.

• This chime requires a 16 Volt, 10 Watt transformer. Check existing transformer for ratings.

• For replacement installation, identify and tag wires before removing them according to terminal
markings: “F”-Front Push Button, “R”-Rear Push Button, and “T”-Transformer.

• For new installations install #20 AWG bell wire in pairs from push button(s) and transformer to
chime. Do not pinch wire or damage its insulation. Heath®/Zenith accessory wire (No. 196C or No.
199C) is available for chime installations.

• Clean wood, plastic, and metal parts with mild soap and warm water. Never use cleaners or pol­ishes. Never use any fluids on the electronic chime mechanism.

Chime does not sound:

• Check Circuit Breaker to Transformer: Reset circuit breaker if tripped.

• Reset Chime: Press Reset button located on front of chime base (see Figure 3).

• Check Chime: Disconnect wire from terminal marked “TRANS”. Have someone operate push but­ton at front door while you momentarily touch the “TRANS” wire to terminal marked “FRONT”. You
will see a small spark if push button, wiring, and transformer are operating properly. Repeat the
steps for “REAR” terminal and rear push button. If wiring between transformer and push button(s)
check out properly, replace chime.

• Check Push Button(s): Remove suspected unit from door frame, disconnect wire from terminals
and touch bare wires together. If chime operates, push button is defective. Replace push button.

• Check Transformer: Momentarily touch the two low-voltage terminals with a screwdriver. You will
see a small spark if transformer is operating properly. If no spark is evident, replace transformer.

Chime sounds but does not complete the tune:

• Check Diode on Front Door Push Button: Verify diode is attached securely to push button (see
Figure 4). If tune still does not sound completely, replace diode.
