What are doorbells

Despite the fact that intercoms are installed everywhere in apartment buildings, personal doorbells are by no means a thing of the past. Our advice site decided to find out what doorbells are, so that you make the right and informed choice of this important addition to the entrance group.

Why do you need a doorbell at all if there is an intercom? First, the driveway intercom can break or be disabled. Secondly, guests can come along with one of your neighbors, so they simply won’t ring the intercom. In addition, one of the neighbors may come to you. And if you just knock on the door, then you may not hear this sound if, for example, the interior door is closed and the entrance sound insulation is at a high level. So the doorbell remains useful and important..

Retro-style doorbells today are mostly used to decorate the entrance group, than to notify the arrival of guests. These retro options include:

• Door knockers. To knock not with your hand, but with a metal mallet. The sound, of course, will be louder, but still not as much as in the case of modern calls. A door knocker in a private house can complement a regular bell that is installed on the gate. Convenient – they called – you need to open the gate, a guest has come. They knocked – the guest got to the front door.
• Door bell. A cord allows you to call it. Looks nice, but since it is suspended from the outside, you may not hear.
• Rotary bell. The loudest option, emits a high-pitched sound similar to a bicycle trill.

Modern doorbells always consist of two parts – the switch, the button is attached next to the front door, and the sounding part is inside the house. All of them are divided into two types:

• Electromechanical. A very popular option. They can be autonomous, that is, they run on batteries, as well as transformer ones – they are connected to the general wiring of the house using a step-down transformer. The button and the bell are connected to each other by a special “ringing wire” passing through the wall. Inside the house, the wire is attached to the wall with stitching brackets, without gating.
• Wireless. Most often they are installed in private houses, where the bell button is located next to the gate, and the receiving, sound part is inside the building. No wires, pressing the button activates the radio signal, which is transmitted to the audio part.

Important! We do not recommend hiding the bell inside the house under a false ceiling! Sooner or later, your equipment will break down and you will have to disassemble the entire structure to get to it.

By the type of signal, all calls are divided into four types:

• Monochromatic. The simplest ones cost from 100 rubles.
• Two-tone. They are “bells”, cost from 150 rubles. According to psychologists, this is the most comfortable option for perception, the lower the sound, the more pleasant it is for hearing..
• With a set of melodies. They cost from 200 rubles. The downside is that the owners can quickly get bored with the melody. In addition, most of these models have a problem – the owner has already opened the door, and the melody is playing out.
• Smart. You can record any melody in mp3 format, adjust the signal duration. Cost from 1000 rubles.

It’s up to you. It is quite possible to install an ordinary electromechanical two-tone bell in an apartment, and for a private house to choose a more “advanced”, wireless one. In any case, this is a very useful addition to the entrance group to the house, about the arrangement of which the portal has already written.
