Doorbell wired: description, selection, connection

Today, before the entrance to almost every modern house, a doorbell is installed , the melody of which notifies the hosts about the arrival of guests. Since the day of his invention, more than a hundred years have passed, and since then, no family has been without this necessary accessory. The task of this simple device is to deliver a loud, clearly audible sound signal when the button is pressed.

How is the doorbell made and how does the door bell work?

To better understand the device of this simplest device, you need to familiarize yourself with its main constituent parts. Such a call consists of an element responsible for supplying electricity; Buttons; Springs; Contacts; Cups; Anchor; A hammer and an electromagnet. By the way, it is the electric magnet that is considered the most basic element, due to which the signal is produced.

The principle of operation of this device is extremely simple. A wired doorbell is a device that emits a beep when power is applied. In order to close the supply circuit, it is necessary to press the button. It is also important that such devices have the ability to separate elements in different places. The bell button is located outside, on the entrance door, and he himself is inside the apartment. The closing and opening of the electrical circuit is due to the presence of the same electromagnet.

Main advantages and disadvantages

A standard wired doorbell is a button that opens or closes the buzzer circuit. The indoor unit of such a device is located in the room, and the outdoor unit is located on the entrance door. To connect these two parts in one piece, you need a wire, for the laying of which you need to drill a hole in the wall.

The drawbacks of such devices include the fact that the bell button has contacts that are under high voltage and need additional protection. The installation of such devices is complicated by the need to use thick wires. Despite the fact that such doorbells do not require frequent maintenance and are characterized by a long service life, they gradually lose popularity, giving way to more modern wireless models.

How to choose an electric bell?

In order for a wired doorbell to serve you as long as possible, several simple recommendations should be followed when selecting it. Buy these devices you need in specialized stores. An experienced sales consultant will help you understand the characteristics of a particular model and choose the best option.

When selecting an instrument, you should listen to it. The sound of a door bell can be standard or in the form of a melody. The volume of the device intended for installation in front of the entrance to a spacious room should be sufficient to be heard from anywhere in the house.

Wired call equipped with an electronic sound conditioner

The source of sound in such devices is the speaker, successfully replacing the traditional electromagnet with the bowl. Most modern models work precisely in this way. In order for the speaker to start programmed melodies, vibrations of different frequencies are applied to it. And in this case you will have the opportunity to choose the sound of the door bell. It can be a quiet buzz or interpretation of popular musical works.

The button of such a device does not supply power to the call, but only starts the circuit in action. Those who are interested in how much the call costs, we will answer that the prices for wire models fluctuate from 300 to 1000 rubles. Everything depends on the availability of additional functions.

Programmable doorbell wired

These devices have a number of undeniable advantages, including:

• The presence of all kinds of sounds that can replace the usual ringing;
• Lack of high voltage on the button;
• The ability to adjust the duration and volume of the call.

To this list you can add the ability to select a specific melody that will be played when the button is pressed. In the simplest models, with each subsequent pressing will sound a completely new melody. In more modern devices you can independently set the desired mode (quiet, normal or security). This is done using the button on the phone.

Self-powered device

To date, some models of wired calls can function from batteries. Such devices can work even in the absence of electricity. The only thing that can not be forgotten is the regular replacement of the feeding elements. As a rule, one set of batteries is enough for six months of normal operation of the call. Typically, these stand-alone models are mounted directly into the front door.

Wired calls with touch buttons and voice communication

Today in stores you can often see improved models, activated by a simple touch of your finger. In such calls there is no mechanical system with contacts. Those who want to know how much a call with a sensor costs, it should be said that the price for such models differs little from traditional buttons. This is because most of them are built on a single transistor with a minimum of strapping.

Instruments equipped with a voice connection are more like intercoms than a classical bell. By clicking on the button of such a device, you can always find out who exactly is on the other side of the closed door.

How to install a doorbell?

This is much easier than it might seem at first glance. Conventional wired models have two power outputs. It is to them and you need to withdraw two wires in order to connect the button and wires from the switchboard.

At the initial stage it is necessary to determine the location in which the device will be located. To limit the route of the wire laying for the button, it is recommended to set the bell at the top or side of the entrance door. For the installation of wired models you will need tape, nippers, pliers, a thin and indicator screwdriver. To remove the ringed two-wire insulated wire outwards, it is necessary to drill a hole in the door frame. The outside wire must be connected to the terminals of the bell button. As for the button itself, it should be securely fastened to the wall.

In the event that the battery is located in the body of the device, the other end of the wire must be connected to the two terminals on the battery. If it is located separately, then the ringing wire extends from the call to the button. In this case, each pre-cut end of the cable is connected to the terminal.

By connecting the bell to the transformer, first of all, it is necessary to connect it to the junction box, after which it is possible to do the above manipulations. At the same time, care must be taken to ensure that the bell terminals are connected to the transformer terminals, giving the corresponding voltage. At the final stage, it is necessary to secure the wires to the terminals in the bell housing. Before doing this, you should carefully read the manufacturer's instructions. Typically, manufacturers describe in detail and as much as possible the connection algorithm.
