Answer by wood42ras
Yes a transformer can fail….It sounds like that is the problem…did you check to see if you have continuity at the door bell…this means that a current can travel thought the wires…if not then something has broken the wire…but like I said the transformer seems to be your problem…make sure if you replace it that you get the same output of 12 volt so you don’t overload the bell….

Doorbell installation?

Question by G Man: Doorbell installation?
I guess I wasn’t too clear when I asked previously. I’m replacing three button to ring the buzzers of three different units. The buttons are right next to one another. When I attached the red “live” wire and the wire running to the first floor buzzer it worked, but I was not pressing the button. It was as if I was just touching the hot wire to the wire running to the units buzzer. Continuous buzzing. I thought I had to press the button to complete the circuit, ringing the buzzer. Can anyone tell me why the buzzer continues to “buzz” even though I’m not pressing the button?

Maybe the button has a normally closed contact which opens when pressed

Doorbell Installation and basic information

There is nothing more embarrassing for a home owner than a guest arriving at the door and finding that the doorbell doesn’t ring or that it gives off a nasty electrical shock when pressed. You certainly don’t want any of your guests with their hair standing on ends. Jokes apart, no home owner should have to face this embarrassment when they have at their hands one of the easiest electrical appliances in the doorbell. Yes, the doorbell is one of the simplest yet most efficient electrical appliances.

Even a novice electrician or a complete newbie to wires and circuits can install a new doorbell or repair an existing one. Yet most people are apprehensive about handling doorbells and often hand the task over to a professional electrician. Others settle for the safer and easier option of replacing the wired doorbell installation for a wireless one that is easier to install and use. Not that it is a bad choice, but isn’t it sad that you have to invest in a wireless doorbell purely because you chickened out at the thought of handling a few screws and wires? This page is aimed at giving you comprehensive and concrete information about doorbells, transformers, wires, batteries and everything in between.

3. Troubleshooting your doorbell

Basic Information: Doorbell Circuit

The doorbell as I mentioned earlier, is one of the simplest yet coolest devices ever created. We live in a world of gizmos and gadgets. We have gadgets that can control everything from the sound of music to the temperature in our home all at the snap of fingers. And here is a device that does nothing but create some kind of noise when a button is pressed. Isn’t that primitive? Not quite. A doorbell works on the very basic principle of electromagnetism and converts it into buzzes, chimes or rings. At the core of a doorbell lie a transformer and an electromagnet (a magnetic device with coiled wire around it). When you press the button of a doorbell, it completes an electrical circuit. Electricity flows through the electromagnet via the transformer. This electricity then activates the magnetic field which is used to trigger some sort of noise making apparatus (differs from one model to the other). Most doorbells and buzzers today run on 16V whereas earlier models used to operate on 10V.

Transformer

The transformer is a tiny device enclosed within the doorbell in newer models and separate in older models. It reduces normal household electric current from 120V to 10 or 16 V as per the requirement of the bell or chime. Usually, all transformers have two permanent wires, one black and the other one white which is used to provide power to the unit from the source. The opposite side of the transformer has two attachment screws which can be used to connect the low voltage wires to it. It is these wires which are in turn connected to the electric bell. Transformers are relatively compact and are designed in such a way that they can be installed directly into an outlet or a junction box.

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.

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.
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 door chimes that have multiple buttons (for the front and back door). Here are the steps to complete the installation.

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.
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.
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.

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.

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

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.

Installing the wireless doorbell

There is a crazy rumor about America and Russia that goes around. According to this saying, America spent millions of dollars in the early 1950′s in trying to create an astronaut pen that could work in space. But each time, they would fail as the ink refused to stay within the ball point pen in zero gravity. Russia on the other hand, took a pencil to space. While I don’t believe the story, the point that I am trying to emphasize is that you can actually avoid a lot of hassles and trouble if you put your mind to it. The wireless doorbell is something similar. Think about all the hassles (if you can call it so) that is associated with installing a wired doorbell. You can avoid it all by installing a wireless doorbell. They are easy to install. Have no wires. And can be installed in minutes by even a novice.

The steps for mounting the doorbell button and the receiver are similar to that mentioned in the wired doorbell installation techniques. You always have an easier option of using double sided adhesive tape to mount it.
If you are replacing an old wired doorbell installation with a wireless one, then you will have to remove the old button from the door and cover any exposed wires with electrical tape. (Follow safety rules mentioned here) You can also choose to bundle all covered wires together with electrical tape.
Install the new wireless doorbell button at a comfortable height on the door. (Over the same hole in case of a replacement installation)
Place the receiver at an ideal location inside the house. Always ensure that you keep it within the operation range of the unit to obtain maximum volume and resonance. Most people prefer installing the receiver in the hallway.
If it is a plug-in model then the receiver has to be plugged in an electrical outlet. If it is a battery powered model on the other hand, then put in the batteries before installation.

Testing the installation

While the doorbell can be tested by simply pressing the button at the front door, that might not be sufficient. Press the button and have someone move from room to room in the house. This will give you a good idea about the places where the sound is least audible. You can always purchase additional receivers to place at different locations in the house (Ideal for multi floor homes). If there is no sound, then either the unit might be faulty or the batteries might need to be replaced. Wireless doorbells might ring for no reason whatsoever. If this is the case, then it is being caused by external interference like garage doors, car alarms. However, there are advanced wireless doorbell models which have built in support to block out external frequencies.

That’s it. Isn’t that easier as compared to installing wired doorbells? You can actually complete installation and testing in less than 10 minutes. So when are you planning to replace your old wired doorbell installation?
