Introduction: Connecting the SimpliSafe Video Doorbell to a Digital Chime

I recently purchased a SimpliSafe Video Doorbell and after installing it I found out that it caused my digital chime to constantly ring. After talking to SimpliSafe, and being told that the doorbell isn't designed to work with a digital chime, they sent me a Chime Connector to see if that would fix the problem. When I installed the Chime Connector the constant ringing stopped but now the chime wouldn't ring at all when the doorbell button was pressed. After talking to SimpliSafe again they told me that I had two options: 1) Replace the digital chime with a mechanical chime, or 2) Return the Video Doorbell and reinstall my original doorbell. I didn't want to replace the digital chime and believed that there had to be a solution to get the Video Doorbell to work with a digital chime. After a lot of Internet searching I found an Instructables posted by NaokiH5 titled "Adapting a Video Doorbell to a Digital Song Chime." NaokiH5 provided a nice wiring drawing but after reviewing it I realized I could eliminate one of the doorbell transformers in his design. Also, during my solution search I came across a lot of postings of people who were just looking for a material list and a wiring diagram they could follow to get their Video Doorbell to work with their digital chime. The following sections provide the Bill of Material and Wiring Diagram that I used to provide power to the SimpliSafe Video Doorbell so it will operate and to get the SimpliSafe Video Doorbell to ring my Heath Zenith digital chime when the doorbell button is pushed. While I only have a front doorbell I also included a Bill of Material and Wiring Diagram showing how I would install two Video Doorbells if I wanted to have a front and rear Video Doorbell.

I hope this helps you get your SimpliSafe Video Doorbell working with your digital chime.

Step 1: Bill of Material - Single SimpliSafe Video Doorbell

I used the following components in my front door, single Video Doorbell installation:

1 - SimpliSafe Video Doorbell

1 - SimpliSafe Chime Connector

1 - Heath Zenith Multi-Tune Chime

1- 120V/16V AC Door Chime Transformer

1 - URBEST HH52P AC 24V Coil DPDT 8 Pins Electromagnetic Power Relay w DYF08A Base

2 - Fairchild Semiconductor 1N4001 Diode, Standard, 1A, 50V, DO-41

18 Gauge Doorbell Wire

I purchased the Chime from Home Depot. I purchased the Relay and Diodes from Amazon. You can use chime, relay and diode components from a different manufacturer as long as their component meets the same specifications.

Step 2: Identify 'Coil' and 'Switch' Side of the Relay

The relay in my Bill of Material has two parts - the relay housing and the base - and may come as two individual items. To assemble, insert the housing into the base, the pin configuration on the bottom of the housing will only fit into the base in one way. Your relay may not look exactly like this but you should be able to identify the 'Coil' side and 'Switch' side using this picture as a reference.

Step 3: Wiring Diagram - Single Video Doorbell

Follow this wiring diagram to install a single Video Doorbell by connecting each wire to the corresponding components and terminals.

Wiring diagram notes:

  • Turn off power to the transformer at the breaker panel when wiring the components together.
  • Line colors used for clarity to show each individual wire run, doorbell wire typically has a red and white wire.
  • Install diodes with cathode end (represented by solid black line on the diode symbol and a similar marking on the actual diode) connected to each terminal as shown.

If you wanted a single Video Doorbell (i.e. for the front door) and a regular doorbell (i.e. for the back/rear door) then follow this wiring diagram for the Video Doorbell and just install the regular doorbell per your chime manufacturer's instructions using the same transformer as depicted in the wiring diagram.

If you don't feel comfortable performing this installation, an electrician can do this for you.

I've included a downloadable PDF if you prefer to have a printed copy to reference when doing the installation.

Step 4: Bill of Material - Two SimpliSafe Video Doorbells

If you wanted/needed to install two SimpliSafe Video Doorbells then your bill of material would look like this:

2 - SimpliSafe Video Doorbell

2 - SimpliSafe Chime Connector

1 - Heath Zenith Multi-Tune Chime

1- 120V/16V AC Door Chime Transformer

2 - URBEST HH52P AC 24V Coil DPDT 8 Pins Electromagnetic Power Relay w DYF08A Base

4 - Fairchild Semiconductor 1N4001 Diode, Standard, 1A, 50V, DO-41

18 Gauge Doorbell Wire

Step 5: Wiring Diagram - Two Video Doorbells

Follow this wiring diagram to install two Video Doorbells by connecting each wire to the corresponding components and terminals.

Wiring diagram notes:

  • Turn off power to the transformer at the breaker panel when wiring the components together.
  • Line colors used for clarity to show each individual wire run, doorbell wire typically has a red and white wire.
  • Install diodes with cathode end (represented by solid black line on the diode symbol and a similar marking on the actual diode) connected to each terminal as shown.

If you don't feel comfortable performing this installation, an electrician can do this for you.

I've included a downloadable PDF if you prefer to have a printed copy to reference when doing the installation.

Step 6: Relay Options

I used a Double-Pole Double-Throw (DPDT) 24VAC relay because I had it available and I knew the terminal configuration. You could use a Single-Pole Double-Throw (SPDT) 24VAC relay in place of the DPDT relay(s) in my wiring diagrams. Just make sure you know which terminals connect to the coil and which terminals connect to the normally closed and normally open switches.

There are lots of other relay options available that can be used in this design as long as you know which terminals connect to the normally closed switch and which connect to the a normally open switch.

    Question 6 months ago on Step 5

    Hello, I have the same situation with two simplisafe doorbells and one Craftmade Westminster C3-PW chime. I’m going to follow the two doorbell schematic but want to be sure about the connections to the chime circuit board. Attached is image of chime board. Please advise on how to use existing drawing for this chime application. Thank you.

    Question 10 months ago on Introduction

    I have wired a Simplisafe Doorbell Camera to a Nutone 4-8 tone chime using your suggested wiring diagram and list of materials. Photo shows the Nutone chime workings and I have added my wiring diagram showing the addition of the rear and side doorbells and the 5 contact points on the Nutone chime. The video doorbell works as it should instead of the doorbell chiming constantly as when I first installed it out of the box. Now my challenge is that the transformer exhibits a significant hum and the motor on the chime unit is buzzing. I understand that this can be caused by the trickle charge to the video doorbell to the camera and leakage of this low level power through the circuit. This low level power back to transformer and the chime is just enough power to get things humming and buzzing. The recommended fix appears to be to insert a 1/2 Watt 10 Ohm resistor between the FRONT and TRANS connections on the chime unit although some argue the resistor needs to be bigger such as 50 Watt 25Ohm. I am not sure I understand how inserting the resistor would interact with the diodes as I believe the purpose of the diodes is to insure that low level power flow through to the doorbell. I would welcome your thoughts and suggestions on how to address the hum and buzz issue while adhering to your wiring and use of the relay.

    Hi Andrew - Have you tried disconnecting the side and rear doorbells at the chime terminal block to see if the buzzing stops? If it does, then try reconnecting each side and rear terminal independently to see if one of those doorbells is causing the buzzing. You may have a partial contact in one of those doorbell switches. You may have had a slight hum before when you had all of your original doorbells installed, if one of them has a partial contact, and it's now noticeable with the Simplisafe doorbell installed because of the draw and additional load from the video doorbell. The other suggestion that comes to mind is to replace the transformer. Transformers will start to hum or buzz when they are starting to fail. I recently had to replace the transformer in my setup because it started to hum/buzz and I only have the video doorbell connected. I'm not sure if inserting resistors will solve the problem because I think the issue is at the transformer.

    DLAG - Thanks for your reply. Picked it up today 5/29. After multiple attempts and even after installing a second transformer and involving an electrician I have thrown in the towel. Simplisafe has sent me a second video doorbell as the first just stopped working after multiple installation attempts. I am now installing the Simplisafe video doorbell with a simple two-note mechanical doorbell. Let see if it works.

    I bought my house new in 1996 and have a Nutone intercomm system as part of my doorbell setup. The house also came with a wired alarm system which worked well until the last few years when I started getting a lot of false alarms. I finally decided to ditch my old alarm system and went with a complete Simplisafe solution including the Simplisafe Doorbell Pro. It did not work because Nutone is a digital system and then I found your article. I am a retired IT guy so my knowledge of hardware at the circuit level is not that get good so I asked a friend of mine who is an electrical engineer to help me out. Your solution worked exactly as documented. We did not run into any issues implementing your solution. I just want to thank you very much for posting this solution.

    Question 2 years ago on Step 6

    I have installed the simplisafe doorbell using your configurations I have sent a picture please advise me if the connections are done correctly. I do not get any response from the doorbell although when crossing the wires at the transformer it appears that I have power. Also do I need a dioade at the doorbell in addition to the two at the relay?.

    Sorry for the delay in responding, your message got buried in my Inbox. You don't need a diode at the doorbell. Reviewing your picture it looks like your chime connector is set up differently than the one Simplisafe sent me. I've heard that they have created a new chime connector to try to resolve this issue but I don't have one of the new ones to work with. I'm guessing that you tried to just install the chime connector without the relay per Simplisafe's instructions and that didn't work since you are trying this configuration. Your wiring connections all look correct. The only thing I can think of is to make sure you have the input side of the chime connector connected to the transformer and the video doorbell and that the chime connector blue and white wires are connected to the correct relay terminals. One other thing to check is that your diodes are oriented correctly. They should have a band marking towards one end of the diode, looks like the band is white on your diodes, and need to be installed per my diagram. If they are installed 'backwards' they will block the flow of electricity.

    Hello all
    I can't seem to get my doorbell to communicate with the chime... both are powered, but ringing the bell doesn't activate the chime. The chime is digital...
    Transformer is 16V.
    Relay is same as specd in directions here.

    Double checked my wiring with your wiring diagram for single door bell and worked the first time. Now am enjoying the digital chimes! SimpliSafe still hasn’t felt the need to be compatible with electronic chimes vs their competitors. Thanks for the solution!

    Question 2 years ago on Step 1

    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?

    Looking at your pictures, I recommend that you put both the relay and the chime connector where the transformer is located; you don't really have enough room where the chime is located to install them and be able to put them out of site. However, since your transformer is on the 1st floor and your chime is on the 2nd floor you will need to run additional wires between the 1st and 2nd floor to be able to make the connections shown in the diagram.
