Installing wired doorbells

Installing wired doorbells is always considered to be a pain by most people who are inexperienced with handling electric wires. However, if you look at it closely, then installation can be pretty simple. Almost any novice Do-it-Yourself person can complete it within 15 minutes.

  • However, always ensure that you follow the rules of safety before trying to install any electrical appliance.
  • Switch off the power before you handle any wiring to avoid an electric shock.
  • Ensure that you run the wires along the wall using supports wherever necessary.
  • Always use insulated staples to handle any electrical wires.
  • Use electrical insulation tape to cover any exposed ends of the wire. Never ever use ordinary tapes to cover electric wires or leave the wires exposed.

 

So, are you all set to begin?

Mounting the bell and the receiver

Mounting the doorbell button and the receiver unit should be easy. However, I am mentioning it because I do not wish to omit any part from the installation.

  1. The first step is to identify the right position for both the doorbell button as well as the receiver. The button should be positioned at an ideal height so that each family member should be able to ring it comfortably without having to stand on the toes or bend down. The receiver on the other hand should be placed in a position so that it is audible throughout the house. If the wall has a drywall finish, then you will have to use toggles or molly bolts to anchor it.
  2. You will need a Power drill and 3/8-inch bit, Insulated screwdrivers, insulated Pliers and a stepladder to complete mounting the doorbell button and the receiver.

 

The single button doorbell

The single button doorbell is probably the simplest of them all. However, it can rarely be found today as most home owners prefer to use door bells or chimes that have multiple buttons (for the front and back door). Here are the steps to complete the installation.

Transformers

  1. Connect one wire to the terminal screw on the button of the doorbell. This wire should run straight (uninterrupted) to the terminal screw on the transformer.
  2. Connect the second wire to the second screw on the button and the other end of this wire should be connected to the terminal screw on the bell.
  3. The third and last wire will run from the terminal screw on the bell to the other screw on the transformer.

 

That’s it. You have completed installing a one button wired doorbell. Test the doorbell.

Wiring for buttons on both front and back doors

The procedure for mounting the doorbell buttons and receivers are still the same. The only difference being that you will have to mount the button at two different places now.

Bell Wire

  • Connect one wire to the terminal screws on either buttons (front and back door) and connect the other end of both these wires to one of the terminal screws on the transformer. (Running the wiring here can be slightly tricky. Ensure that you have a proper plan chalked out on paper before you begin)
  • Connect the second wire to the second terminal screws on either buttons and connect the end of these wires to the terminal screw on the bell.
  • Now connect the third wire to the remaining terminal screw of the wire and the other end to the second terminal screw on the transformer.

 

That’s it. However, please be informed that in this type of a doorbell, both the buttons will activate the same bell sound or chime.

Wiring for a doorbell on the front door and a buzzer on the back door

Now let’s get into slightly more advanced installations. In the earlier example, we noticed how we can connect two buttons to the same doorbell. However, since they activate the same sound, it becomes a tad difficult to point out the exact door that the visitor is at. So, to solve the problem you can install a buzzer for the back door and a doorbell for the front door (This installation is not for the buzzer-bell combination model). Sounds difficult? It isn’t.

Diagram

  • Connect one terminal screw of either buttons and connect the other end of these wires to one terminal screw on the transformer.
  • Connect the second terminal screw of the front door button and connect it to one terminal screw on the doorbell.
  • Connect the second terminal screw of the back door button and connect it to one terminal screw of the buzzer.
  • Connect the second terminal screw of the buzzer to the second terminal screw on the doorbell. Yes, the two units are connected.
  • So far so good. Now here comes the tricky part. Connect a wire to the same terminal screw on the doorbell (which is connected to the buzzer) and connect the other end to the remaining terminal screw on the transformer.

 

That’s it. This installation is ideal if you already have either one of these devices installed and wish to add the second one. However, if you are planning fresh installations then you can opt for the bell-buzzer combo device to reduce costs.

Installing a door chime

Doorbell

Most homes will have a door chime and not the vintage bells and buzzers. However, their wirings are pretty much the same. One thing that you need to ensure (if you are installing a separate transformer) is that the transformer matches the voltage requirements of the chime. If the transformer is built in the chime unit, then installation becomes a cinch.
