Types of doorbell Chime

Every one of us has a doorbell as well as a doorbell chime in their house. Now, the type of chime you could have depends on the age of your house. There are two types of doorbell chime you can find.

1. Mechanical doorbell chime

Usually, old day’s house contains a mechanical doorbell chime. It produces a ‘ding-dong’ sound while the bell button is pressed. So if your home is old fashioned, you will definitely have a mechanical doorbell chime.

2. Digital doorbell chime

Used in new-made houses. It produces a melody instead of a ding-dong sound. So, if you buy a new house recently, you will have a digital doorbell chime.

Mechanism of a doorbell chime

Before you proceed to the repair section, it is vital that you know about the mechanism of a doorbell chime.

Digital chime has two systems. One is wired system and another is the wireless system or battery system. However, mechanical doorbell chime has only one system in it and that is the wired system.

So, let’s talk about the wired system first. And then the wireless system or battery system.

A. Wired system:

This system has three wires connected successively to the front doorbell button, transformer, and rear bell button. In the chime box, you can also find three connecting panels indicating front, transformer and rear panel.

It has two plungers one connects to the front bell button and the other connects to the back bell button. They generate ding-dong sound when they are magnetically pulled and released while the bell button is released.

Mechanical and Digital both have wired system. There is a little diode that is used in the bell button if it has a digital chime.

B. Wireless system or battery system:

The wireless system basically refers to simply put batteries in the chime. There are one-battery chime and two-battery chime out on the market.

How do you choose your doorbell chime

Now that you've come this far, you have already have had a basic knowledge about chimes. But in case if you want to replace a chime box, what would be the new one? Would it be a mechanical chime box? Or, a digital chime box?

You see, Mechanical chime has an only wired system. In case if you lose electricity or your wire gets damaged or melted you have to replace it with the wires.

On the other hand, Digital chime has both wired and wireless system. In case if something happens to the wired system, you can always use a battery system. Well, in this part, I believe that you have already got your answer.

It's digital chime. It privileges you with both wired and wireless system. Moreover, you can customize what kind of melody you want if someone knocks at your door. Cool! Right?
