Electric wired doorbell: types and methods of connection

Practically in every modern house there is a door bell, which with its melody notifies of the arrival of guests. The task of such a simple device is to give a loud, well-discernible sound signal when a button is pressed.

The wired doorbell is distinguished by the presence of a variety of melodies and sounds that a person chooses at his discretion. Types and features of the device, its connection to the network is discussed in the article.

Call device

To understand the device and the principle of the electric bell, it is necessary to become familiar with its main components.

These include:

• An electric magnet that serves as a signal.
• Hammer.
• Anchor.
• Directly bell or cup.
• Contacts.
• Spring.
• Button.
• Battery or electricity supply.

The principle of operation and features

The principle of operation of a wired electric bell is based on the proximity to each other of an electromagnet and an anchor.

Wherein:

• A brass contact of a movable type is placed near the anchor.
• When there is no electricity on the electric magnet, the contact is pressed to a screw section connected to one terminal.
• The other terminal is connected to the coil of the electric magnet, and its second section is connected to the anchor.
• When you press the bell button, the circuit closes, the anchor device enters the coil, which is attracted to the pole by an electric magnet.
• Next, the hammer hits the surface of the bell cup.
• The brass contact of the rolling type, opens the circuit and moves away from the screw section.
• Through the coil of the electromagnet stops the flow of current.
• Electromagnet no longer attracts anchor.
• The spring shifts the anchor from the pole of the electromagnet.
• The contact is pressed again to the screw, closing the circuit.
• The current starts to pass through the surface of the coil again, the hammer beeps, and the whole process repeats again until the button is stopped.
• If the button, which is responsible for the current interrupter, is closed, the anchor constantly oscillates and the hammer hits the cup, which reproduces the signal.

The main function of the electric magnet is self-switching of the device, its presence allows you to close and open the electrical circuit.

The table shows the advantages and disadvantages of the structures:

Types of electric calls

Door wired calls can be:

• With electronic sound shaper.

The use of various integrated circuits, allows you to apply to the speaker vibrations of different frequencies. In this case, melodious trills, sounds of nature, specially programmed melodies or sounds, which can range from a low hum to playing well-known musical works, can be made.

In this case, the button serves to launch the circuit into action. To control the call there is no need for a button to supply high voltage directly from the network. You can use voltage from 3 to 12 V, which will be enough to form a signal. In this case, the wiring is significantly simplified, smaller wires are applied, and the button has a longer service life.

Tip: When using such devices, do not hold the button permanently. It is enough to press it briefly once, and the call will work, having played all programmed melody.

Advantages of the design:

1. the ability to get a variety of sounds, replacing the usual ringing;
2. adjust the duration and volume;
3. lack of high voltage on the button.

The disadvantages include the need to supply power to the call.

• Programmable wire calls for doors.

To all the advantages listed above, the ability to select a particular melody, or a recording to be played by pressing a button, is added. The easiest case is to play different melodies each time you press a button.

With more complex options set different modes: for protection, normal, quiet. For this purpose, a mode switch button and a device for volume control are installed on the case of the bell.

For example: for the watchdog mode, after playing the specified music, a loud dog barking appears, daring unwanted guests.

• Designs with autonomous power.

Autonomous power supply is usually inherent in wireless calls, but there are models of wired designs that run on batteries. Their main advantage is the ability to work even in the absence of electricity, with regular replacement of power elements.

One set of batteries can serve for normal operation up to one year. Such autonomous calls are mounted directly at the door. In this case, the call and the device button are located on its different sides.

• Calls with touch buttons that do not have to have a mechanical system with contacts.

There are very simple circuits that give the signal to turn on the sound from the touch of a finger. Usually they consist of one transistor and a minimum number of strapping. Lack of calls - no response when touched through gloves.

• Wired calls with voice communication.

Such systems are closer to intercoms. But there are also simple, cheap devices, with a microphone and speakers. When you press the guest on the button there is an opportunity to ask who came before opening the door.

Electric bell selection

Tip: Before picking up an electric wired bell, you should familiarize yourself with some recommendations.

Instructions for choosing a device offers:

• Contact a specialized store where experienced consultants provide extensive information on many types of doorbells.
• Determine the type of electric bell for your home. It should take into account its cost, appearance, connection method, the ability to adjust the volume and ease of mounting the device with your own hands.
• Identify the ringtone.

Tip: For a large house, you must purchase a loud device so that its sound can be heard even in the most remote corners of the building.

• The gongs that emit trumpet sounds are distinguished by their excellent design and beautiful appearance.
• A useful feature for a call is to highlight it in the dark. For this, small LEDs or luminous materials are used.

An excellent solution for installing a call in a private house, in the country - to purchase a wireless electric bell. One of its parts is mounted on the gate, and the second in the house. The use of a wired bell will be inconvenient due to the complexity of installation and the high cost of laying the cable.

Doorbell Installation

Button and sound panel devices are connected by wires.

By the type of mechanism of construction are:

• Hammer.

• Zummer.
• Kolokolchikovymi.

They differ in the internal device and the principle of action. Work from a network and from the battery.

To connect electric wired calls you must purchase:

• Electric drill.
• Dybella.
• The knife is construction.
• Insulating tape.
• Screwdriver indicator.
• A set of screws.

One or two buttons can be connected to the lock, for example, if there is one common vestibule for several apartments. In this case, one is placed in the vestibule, and the second on the landing in front of the door.

In this case, the device wiring diagram will have two parallel buttons. After clicking on any of them the chain closes and the mechanism will work.

For the correct connection of the doorbell, it is worth watching the video in this article.

Cable wiring and wiring diagram

An electric bell cannot work without electricity, which requires wiring to the place of attachment of the device. Usually for the operation of the products need an alternating current with a voltage of 220V.

The cable can be two-core or two single-core. Wires in cross section of at least 0.5 mm ?. But too thick wires should not be used - the power consumed by a wired call is small.

Tip: The material of the wires must be used the same as for the wiring of electricity throughout the house or apartment.

Different types of products have their own wiring diagram. Usually, during the construction of apartment buildings wiring is laid under the standard door appliances.

When building a house on your own or connecting a wired electric bell, you can select products with any wiring diagram and lay your wiring to it. The call connection circuit usually copies the circuit of a conventional switch exactly, the simplest of the electrical circuits.

Wherein:

• The light bulb is replaced by a sound mechanism.
• Instead of the switch - the button.
• Zero is connected to the sound panel, and the phase is connected to the button.
• Both elements are interconnected, as seen in the photo.

• Pressing the button closes the phase and contributes to the sound signal.

Installation mechanism for sound reproduction

Tip: The device is powered from the mains, which requires compliance with safety rules when working with electrical appliances. Connecting an electrical product is necessary only after turning off the power in the entire apartment.

When a doorbell is connected to a voltage, its contacts and wiring in the apartment are connected. If they are very long, the wires are cut and the ends are trimmed with a construction knife.

Further:

• After connecting the wires, they need to be slightly squeezed with pliers, which will ensure the reliability of the connection and improve the contact.
• Connections are isolated.

• The operation of the device is checked.
• When connecting the four-wire mechanism to a two-wire wiring, the zero and phase involved in connecting the call are determined.
• The remaining wires are carefully connected to each other.
• All elements are carefully insulated.
• The work of the call is checked.
• The device is attached to the wall usually in the hallway or corridor.
• Within a radius of about one and a half meters from the bell there should be no radiators and any heating devices.
• In the wall at the installation site, a hole is drilled and a panel for the sound mechanism is fastened with dowels and self-tapping screws.
• A hole is drilled in the frame of the door, through which the wires that connect the wires of the button and the sound bar pass.

Setting the call button

There are two contacts in the bell button, one of them is spring-loaded. Pressing the button touches the second contact, the circuit closes and the mechanism begins to ring. When the button is released, the contacts open.

The button brings two wires connected to its two pins. Connections are carefully wrapped with tape or firmly fastened with terminals, depending on the design of the device. The button itself is fixed on the wall through a wooden socket.

All wired door bells are devices that allow you to give a signal to a person sitting behind a closed door. What design to choose everyone decides for himself, as long as the signal is well heard and has a pleasant sound.
