CHIME INSTALLATION
IMPORTANT: Proper installation requires a diode on the front
door push button. See Diode Installation Instructions (page 5)
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 chime mounting location. IMPORTANT: This chime
requires more mounting surface than most other chimes. Use
the dimensions in Figure 1 to help determine the proper loca-
tion of the chime. If chime will not fit in the same location as
the existing chime, then contact a licensed electrician to move
the existing wiring to a more suitable location.
Illustrations may vary from actual chime unit.
