In the olden days when people used to call home from a distance then they had to knock on the door and wait for someone to open it. But now days it is not necessary to knock on the door as we have smart and wireless doorsbells which can be easily controlled from the outside. These doorsbells are usually made up of three wires.
Here we will discuss about what are these 3 wires that can be used in the doorbells and how to wire a doorbell with 4 wires.
What are these wires?
These wires are the power supply wires which carry electricity to the bell. There are 4 wires and one of them is connected to the main power supply. The other three wires are used to ring the doorbell.
So, let’s see the 4 wires. The power supply wire is black and it has the symbol of a triangle. This wire is connected to the main power supply and it is usually grounded. The ringing wire is white and it is used to ring the doorbell. The third wire is red and it is used to make a signal. The fourth wire is blue and it is used to detect the signal and when there is a signal then it makes sound.
Now, let’s see the different types of doorsbells which use these 3 wires:
1. Push Button: This is the simplest doorbell which uses only the power supply wire. You have to push the button and this pushes the current through the power supply wire and then it will ring the bell.
2. Wired: Wired doorsbells are very popular in the market now as they are easy to install and you don’t need any wires to work. These doorsbells are usually wired with 3 wires.
3. Wireless: These doorsbells are the latest type of doorsbell which are wireless and they are the most popular and easiest to install. These doorsbells are also known as smart doorbells as they have some advanced features like motion sensing and photo detection.
