Installation Guide

Remove
your existing
doorbell
(optional)
If replacing an
existing doorbell,
shut o power at the
breaker. Then remove
it from the wall and
disconnect the wires.
If wiring your Ring Doorbell to an existing doorbell, a
transformer with a voltage of 8–24VAC is required. If wiring
directly to a transformer, a resistor must be used.
DC transformers and most intercoms are not supported.
Install the diode (optional)
If you’re wiring your Ring Doorbell to a
digital doorbell – you’ll know it’s digital if it
plays a synthesized melody – then install the
included diode.
If your existing doorbell is mechanical, DO
NOT use the diode, as it can damage your
existing doorbell.

The lighter band on your
diode should be on the
same side as the wire
that runs to the “Front”
terminal on your bell.
If you don’t know which
side this is, don’t worry,
since wiring the diode
the wrong way can’t do
any harm.
If your bell doesn’t ring
when pushing the button
on your Ring Doorbell,
just reverse the wires on
the back of your Ring
Doorbell and try again.
