Adapting a Video Doorbell to a Digital Song Chime

Introduction: Adapting a Video Doorbell to a Digital Song Chime

Long story short, Best Buy told me I could not install the Simplisafe Doorbell with a song melody door chime. Reading hundreds of posts said it can't be done. Simplisafe said can't be done but supplied a kit anyway. The connector kit is for a bar striker chime with a buzzing sound problem. A relay solution presented online also failed to provide extended power for a whole song to play. Challenge accepted! My simple solution is to run 2 independant power supplies and a relay to simulate a button push. Installing the diode included with the chime at the relay as if that was a button. The second diode is to quiet whatever choppy signal the Simplisafe connector is putting out so the relay coil behaves. I have no electonic background so please comment on why this works if you know. I mostly use the force. Also, I don't know if this works with other video doorbells with similar issues.

Step 1: Buy Parts

Need:
•Video doorbell
•16V 10VA Transformer
•16 song digital door chime
•Diode ( 2 ) comes with chime
•12VAC DPDT relay
•Relay base for above
•Simplisafe Chime Connector SSDBCC3
•Bell wire

Step 2: Install Components and Wire Chime

Have transformer(s) installed. Mount relay somewhere between transformers. Install diodes across coil and n/o and n/c contacts on the switched output side. Wire chime transformer to relay input. Wire relay n/o to "F" on chime terminals. Wire chime terminal "T" back to relay. If you have a back door stadard bell button wired to "R", you will need a 3rd diode at the button.

Step 3: Wire Video Doorbell and Chime Connector

Mount doorbell. Clip the included metal terminals on the connector and prep to bare 1/4" of wire. Install bare wire at relay coil terminals, with the diode. Wire doorbell to Connector, Connector to doorbell transformer, and back to doorbell.

Step 4: Chime Connector Kit

This gizmo provided by Simplisafe SSDBCC3 reduces line voltage from 19.6V to .003V at rest and then a clipped signal about 18v for about 13 seconds. Long enough to trigger the relay but since a modified wave, can't power the doorbell directly. Low enough that the relay won't trigger until the "button" is pressed.

Step 5: SPDT OR DPDT Relay?

You can use a single throw, double pole relay. I chose a double throw so I can run a light bulb in the basement on the other circuit when the doorbell is pressed. It's a switch so the possibilities are endless. You could trigger a sensor to start recording on a dvr or start a dog barking recording in different rooms. Have fun!

    Question 5 months ago on Introduction

    Hello, attached are my transformer (located on 1st floor) and chime located on 2nd floor. Would anyone be able to explain where the chime connector and the relay need to be placed?

    Tip 11 months ago

    A single 16 volt 30va transformer should easily allow elimination of the second transformer. I'm able to power 2 electronic door chimes using this relay technique with a single higher va transformer. Do not use a 24 volt transformer as it will burnout the SimpliSafe chime connector. (I learned that the hard way.)

    How did you acquire a replacement SS chime connector as i am using a 16 volt 10va transformer and after installing the relay fix my doorbell chime worked only 1 time then no more ding dong so after completely removing the relay, electronic chime and trying the SS chime connector with my mechanical chime my doorbell chime was still dead i then removed the SS chime connector and the mechanical doorbell chime worked but i am right back to where i started no electronic chime just the mechanical chime with a slight humming noise .

    Question 1 year ago on Step 3

    I have a SimpliSafe video doorbell/video camera as well and would like to copy your example. Can you supply the manufacturer & model number information (or supplier info) for the relay used in the example?

    Hi,
    Thanks again for posting this. It's been helpful. I managed to get this to work with a wireless honeywell doorbell.

    Does it matter what direction the diode on the coil side is going? I ask because I burned out my doorbell-side transformer after two weeks of working without issues.
    I may have a short elsewhere but I kind of doubt it.
    I'm not entirely sure I know what's going on in the chime connector but I can't imagine I where else a short would occur.
    Has this happened to anyone else?

    Thanks!

    Thank you!
    Wanted to let you know this worked for me.
    I didn’t want to buy a new doorbell (loved my multi song digital chime)
    I was lucky enough tht my house was wired with a 4-wire doorbell wire so hooking up a second transformer was no sweat.
