Doors

To inform the owner of the house about the guest's visit, set the doorbell. More is not needed from such a device, so the models do not differ in a wide variety.

The article offers to get acquainted with the types of designs, their features.

Varieties of calls

Before you install the bell on the front door is to get acquainted with the types of structures presented in the table:

Call type	Special features
	These are simple products only on the principle of action. Such a retro doorbell can be a real masterpiece: Bronze-molded head of an elephant, boar or lion. Graceful hand that knocks on the door. Women's boot. Mythical creature. The lack of design - the inability to ensure good sound of the bell. Improved versions of products are being produced, for example: mechanisms with spring-loaded buttons connected to levers that reciprocate under pressure. Most often, such designs are used by an additional element of decor, to the chosen style of doors.
	In such a mechanism, electricity plays the role of a trigger for a lever that manually moves in mechanical calls. The principle of the bell: the magnet transmits the progressive movement of the hammer, with the stress of which on the resonator, the sound is extracted.
	Quite popular model. Its principle of operation is based on the transfer of electric current to the coil. Then the shock mechanism interacts with the metal plate, which serves as a resonator. The volume of the call is influenced by its size. The main advantages of the device: Duration of operation. Easy installation. Affordable price. Disadvantages: the need for electricity, the inability to change the signal with a monotonous sound.
	The remote doorbell is usually installed near the gates and gates in private homes (see Radio doorbell: types and advantages of wireless devices). Design advantages: No need to purchase an extra cable. The range of action - up to one hundred meters. Ideal for places where there is no electricity. Disadvantages: do not tolerate low temperatures, stop working if there is a concrete or metal barrier between the main segments.
	These are the most popular and versatile products (see Electric wired doorbell: types and methods of connection). They can publish several melodies, phrases, songs. The main advantages are reliability, easy installation.
	Door bell with pipes or gong, is a normal bell that connects to the network 220W. Its difference from other devices - the sound is generated by two brass tubes of different lengths, which contributes to the excellent sound transmission. In addition to the original sound, the bell gong fits perfectly into any interior. Its front panels or overlays can be of different colors, there are elements in the form of clocks showing the present time.

By type of signal calls are:

Monochrome buzzer. These are the simplest and cheapest products.
Two-tone or gongs, bells. From the point of view of psychologists, these are the most comfortable devices.

Tip: Buying a call costs low frequency. It will be nicer to the ear.

With a set of tunes. Such sounds are pleasant only for a short time. Then they start to annoy.

Such models work independently: after opening the door, the song continues until the end of the musical phrase embedded in the program.

Choosing a doorbell

When purchasing a call for your home, you must follow some rules.

These include:

For large homes require "loud" calls.

Tip: It is advisable to purchase models with multiple receivers. If this is not possible, you should choose an additional one or two receivers that are compatible with each other.

Batteries for the call should be standard to make it easier to find the power source. It is more efficient to use rechargeable batteries.
Simple and easy device installation. The easiest way, the mount to perform on a double-sided tape.
Having a pleasant sound for long-term operation. Preference is better to give a call with a set of melodies, with adjustable volume of sounds.

Pleasant and interior-compatible design. This includes:

The form of the call and its buttons.

The case material, which can have a natural texture with imitation of stone, wood, suede, leather.
Colour.
When transmitting by radio - no wires.
When the button is illuminated, it is easier to find it in the dark.

Functionality.

In this case, preference is given to models:

With telephone and voice recorder.
With built-in surveillance camera and the ability to transfer a call on the radio.
With a camera for video recording.
With door control in the distance.

Remote call должен иметь гарантию, оформленную соответствующим образом.
The quality of the call. This should take into account:

The strength of the buttons and body.
The reliability of contacts, the button should be well protected from moisture penetration.
Greater safety of housing provides a multifunctional remote call.

Call setup

Any model has a manual and installation diagram.

Wherein:

Outside, near the door, a button is attached, from which insulated wires to the junction box and the housing are separated.
For wiring in the door frame or wall, holes are drilled.

Tip: The call should be set so that it can be heard from everywhere.

A single or strong wire is used, the cross section of which is up to 0.5 mm. Telephone "noodles" can be selected for low voltage circuits. In this case, you should not take a large cross section - the power consumption of the call is small.

Tip: The core material should be purchased the same with the flat wiring. Most often it is copper. The aluminum wire may deform after being fastened with screws to the terminal blocks, which will require periodic tightening.

The safety of some models is provided by the power supply voltage of 12V, which is obtained through a transformer connected to the electrical network.

Details of the installation design is shown in the video in this article.

Call connection

Before you connect the device, you need to carefully study the wiring diagram:

This is usually a closed circuit with a serial connection of the bell and the button. Pressing the button closes the electrical circuit and generates a signal.
Sometimes it is necessary to install two buttons for one bell, which are connected in parallel between themselves. When you click on any of them, the bell will beep.
When connecting two calls in a large house, one is located in the hallway, the other - in the distance, for example, in a workshop or garage. Calls are connected in parallel. In this case, you will need a button with three contacts or a dual switch. Any inclusion results in the work of one of the calls. The weak point of the devices is its contacts, which do not work when water enters them, which leads to the closure of the circuit and the constant sound of the signal. Then nothing remains, as the doorbell to disconnect.

Operation of an electronic bell for doors

The instruction manual of the call offers:

Connect the device according to the scheme.
Press the on / off button located at the bottom of the structure.
The call can work in two modes:

sequential search of melodies in a circle, with the control button pressed;
the sound of one melody, while holding the control button.

Mode change. At the same time, the control button can be turned off or click on it.
When you select one melody, the control button is pressed to start its sound or after it ends. Further pressing the door button will continue the sound of the selected melody.
When you switch to the sequential selection of melodies, the control button is pressed. To play a new melody, press the door button.
The volume is adjusted by turning the “volume knob”.

Making a simple call

The simplest device, as in the photo, can be assembled using an old phone, the resistance of which is 10-12 kΩ and a button. In this case, the sound will be simple, not annoying, which is difficult to confuse with other sounds. There is a volume control.

Assembly procedure:

A call is pulled out of the device.
To one of its ends soldered resistor, the power of which is not less than 2 watts.
To another - the button.
Going to the serial circuit of connecting the device to a voltage of 220V.
The device can be disassembled, put in the hallway, and through the wires to connect it to the network and the button.

A call from an old toy

The call can be made from an old toy that has a music module.

Before you make a doorbell with her own hands from a toy, she understands.

To build a call you need:

Find the circuit board to play the sound.
On the details there are contact pads, on which there are contactors made of electrically conductive rubber.
When you close any of them, the sound will begin to sound in the speaker.
To operate the device as a bell, a button with a two-wire cable is soldered in parallel to any gatekeeper.
The circuit is powered by batteries connected to the toy.

When choosing and installing a doorbell on batteries or from the power grid, you need to remember that this is, above all, a reliable person’s assistant. The design and melody of the device are chosen according to the preferences of the owners, and when installing the main thing - to ensure the safety of the device.
