How Does a Door Buzzer Work?

A door buzzer is an essential component of any building’s security system. It allows people who are inside the building to control who enters without having to physically open the door themselves. However, many people may not know how exactly a door buzzer works. In this article, we will go over the basics of how a door buzzer works, including the different types of buzzers and how they function.

What is a door buzzer?

A door buzzer is a small device that is mounted on or near a main entrance door. It is composed of several components, including a buzzer, a button, an intercom, and a power source. The buzzer is what emits the sound when someone rings the doorbell. The button is what visitors push when they arrive. The intercom allows visitors to communicate with whoever is inside. Lastly, the power source is what powers the entire system.

Types of Door Buzzers

There are two main types of door buzzers: wired and wireless. The wired buzzer is connected to the building’s electrical system and requires professional installation. The wireless buzzer, on the other hand, is battery-operated and can easily be installed by the user.

Wired Door Buzzer

The wired door buzzer is a more traditional option that is commonly used in larger buildings or offices. It is a bit more complex than the wireless buzzer, as it requires wiring and connections to the building’s electrical system. In general, the wired buzzer is considered more reliable than its wireless counterpart since it does not have to rely on batteries.

How it works:

  1. When a visitor pushes the buzzer button, a signal is sent to the buzzer itself.
  2. The buzzer then makes a sound, which alerts those inside the building.
  3. If there is an intercom, the visitor can then speak with whoever is inside and request access.
  4. The person inside can then use a switch or button to unlock the door, granting access to the visitor.

Wireless Door Buzzer

The wireless door buzzer is a more modern option that is commonly used in homes or small offices. It is much easier to install than the wired buzzer, as it does not require any wiring or connections to the building’s electrical system. However, since it relies on batteries, it is considered less reliable than the wired buzzer.

How it works:

  1. When a visitor pushes the buzzer button, a signal is sent wirelessly to the buzzer, which is located inside the building.
  2. The buzzer then makes a sound, which alerts those inside the building.
  3. If there is an intercom, the visitor can then speak with whoever is inside and request access.
  4. The person inside can then use a switch or button to unlock the door, granting access to the visitor.
