Wiring at the transformer
When attaching the new chime at the transformer, connect the new wires to the same wires and screws that the wires from the old chime are connected to.
The most difficult part of adding a new ringer is tracking
down the cables. Although it's easy to connect a new
“doorbell cable” (common is 18- or 20-gauge CL2 type or
the equivalent) at the existing doorbell chime,
it may be difficult to run concealed wires to a basement
shop or other remote location. It may be easier to make the connection at the low-voltage
transformer that powers the doorbell, especially if
it's near the shop. Often the transformer is mounted on the
electrical service panel.
If you're connecting it at the chime, note the three screw
terminals labeled “front,” “back” and “transformer.” Connect
a wire to each and then simply make sure the three wires
connect to the same terminals on the new chime. There's no
uniform color-coding for doorbell wires.
Add a second chime cable at the transformer, exactly like
the cable to the existing chime. Your existing transformer
may not be powerful enough to handle both chimes. So
if you get a weak sound, replace the transformer with a
15-20VA (volt amp) unit.
