CHIME REPLACEMENT 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.
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 3).
