CHIME REPLACEMENT INSTALLATION

IMPORTANT: Proper installation requires a diode on the front door push button. See

Diode Installation Instructions (page 7) after completing steps 1 through 10 below.

Note: Electrical work must be in accordance with national and local electrical codes. If in

doubt, consult a qualiﬁed electrician.

1. Verify transformer power rating. Power must be supplied from a 16 Volt AC, 10 Watt or a 16 Volt

AC, 15 Watt transformer (Heath®/Zenith models 122C, 121AC, or 125C).

2. Remove cover from existing chime.

3. Label all wires before disconnecting. Using masking tape, mark each wire according to existing

chime terminal markings.

• “F” – Front Push Button Wire

• “T” – Transformer Wire

• “R” – Rear Push Button Wire*

4. Disconnect all wires from existing chime.

5. Remove existing chime base from wall.

6. Determine proper chime base orientation. The chime cover style will determine orientation.

7. Determine cover mounting type. For hanging type covers, cover pin should be exposed (see Figures

1 and 4).

8. Route wires through wire entrance hole in new chime base.

9. Mount chime base to wall using screws and anchors provided. (Drill 7/32" diameter pilot hole for

wall anchors.)

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

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

11.Install chime cover (see page 6).

12.Connect diode to front push button (see page 7).

*Note: Some installations may not include rear door push button.

MOUNTING SUGGESTIONS

• Power must be supplied from a 16 Volt, 10 Watt transformer or 16 Volt, 15 Watt transformer (Heath®/

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

• Mount door chime in a central location so it can be heard throughout the home (for new installa-

tions).

• 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).

Note:

• A push button with a factory installed diode (indicated by a decal on the back of the push button) is

included with some models.This push button may be used to replace your existing front door push

button. Additional diodes will not be needed and should not be used.

TROUBLESHOOTING

Chime does not sound:

• Check the Group Selection Switch: No tune will play when the Group Selection is in the “OFF”

position.

• 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.

• CheckTransformer: Test transformer voltage output with a volt meter.If a volt meter is not available,

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.

• Check Push Button(s): Remove suspected push button from door frame, disconnect wire from

terminals and touch bare wires together. If chime operates, push button is defective. Replace push

button.

Chime sounds but does not complete entire selected tune:

• Check Diode on Front Push Button: Verify diode is attached securely to push button (see page

7). Chime may not function properly if a diode is installed on more than one push button. Note:

Some push buttons have pre-installed diodes. An additional diode should not be added if the push

button has a pre-installed diode.If selected tune still does not sound completely, replace diode (Type

1N4003-200V-1A, available at local electrical component supplier).
