Preparation

Step 1
Step 2
To prepare for installation:
Before beginning setup, there are some essential preparations to make.
TURN OFF THE POWER RUNNING TO
YOUR EXISTING DOORBELL AND CHIME
BOX AT THE BREAKER (See Figure 1).
Test that power has been disconnected for
both the doorbell and chime box power by
pressing the doorbell. There should be no
chime sound.
Always be careful when handling electrical
wiring. If you’re not comfortable doing it
yourself, then consult a licensed electrician.
Remove your existing doorbell and
disconnect wiring (see Figure 2). Make sure
to bend the power cables so they do not fall
through the hole in the wall.
IMPORTANT: 16-24 VAC is required. If your house does not have this voltage, you will
need a 16-24 VAC doorbell transformer or you can consult with a licensed electrician.

Wiring the chime
6
You must determine the type of doorbell chime you have in your home: electronic or mechanical.
Not sure? If your doorbell chime is a classic *ding-dong* sound, chances are your chime is mechanical.
If your doorbell sounds more like a melody, then your chime is electronic. If you are still not sure, remove
the cover panel of your chime box - if you nd springloaded levers and a physical metal chime, you have a
mechanical chime.
For users with a mechanical chime, follow the extra step below to complete the installation.
1. Remove the cover panel of your doorbell
chime box.
2. Loosen the screws labeled FRONT and
TRANS using a Philips head screwdriver. Do
not remove the screws, and be sure to detach
any connected wiring (see Figure 1).
3. Connect the included chime kit to the green
terminal on the end of the included wire
harness (see Figure 2).
For mechanical chime owners:

Note: You may connect either
wire to either connector.
4. Connect the wiring from the chime kit to
the FRONT and TRANS connectors in
the chime box. Ensure that the existing
wiring stays connected as well (see
Figure 3).
5. Mount the chime kit to the inside of your
chime box, or along the cover plate of the
chime box, using the included
double-sided tape (see Figure 4).
IMPORTANT: Use the included
double-sided tape to ensure the chime kit
and wires are not touching the chimes
or any moving components inside the
chime box, or the doorbell chime will not
sound correctly.
