Types of calls

There are three main types - mechanical, electromechanical and electronic.

  1. Mechanical call. It is used most often as an element of decoration of a certain style of the door. It is used mainly in hotels, cafes and restaurants. Less often in private homes and almost never in high-rise buildings. Its advantage is precisely the correspondence to the necessary style.

  3. Electromechanical. Quite common calls. The principle of operation is simple - the electric current is fed to the coil, so that the impact mechanism contacts the plate( most often metal), which plays the role of a resonator. The sound volume depends on the size of the resonator. Advantages of these products:
    • The service life is long enough.
    • Simply mounted
    • Simple call device as a whole.

    The disadvantages are as follows:

    • In order for sound to appear, it needs electricity
    • The signal does not change and most often it's a monotone melody.

  5. Electronic calls. They differ from electromechanical with their own ones - it is completely electronic, and the sound comes out of the speaker. Usually such devices allow you to adjust the volume and offer a choice of several tunes. In turn, the given type of calls is divided into two subtypes:
    • Wireless electronic call. Very convenient for the owners of houses, since there is no need to pull the wire. After all, most often the bell is mounted near the gate( gate), and not the entrance door. The range of this device is from 30 to 100 meters, which depends on the needs of the customer and call model. It is also an ideal choice for places where there is no electricity. This doorbell has a number of advantages: there is no need to conduct wires and drill walls, tightness, installation in the absence of electricity. There are several significant shortcomings: they are subject to low temperature, can fail in the severe winter, can not work if there is an obstacle of concrete or metal direction, a lattice or a wall between its two parts( the first - the gate, the second - inside the room).

    • Wired device. The most standard and common. The sound is made by pressing the button, which causes a short circuit in the electrical circuit, and a signal is emitted. Such calls were in most Soviet apartments. Nowadays it has been modernized and offers several tunes to choose from, and less often quotes from films.

    • The advantages of this choice are the following: simplicity and reliability, the ability to work in virtually any environment. Of the shortcomings can be identified only the need to stretch the wires and installation only in those places where there is electricity.

What choice should I make?

Door bell must be purchased based on existing housing. If this is an ordinary apartment, then the best thing is electronic wire. For a house in the forest - wireless. Electromechanical options can be used in offices, and mechanical ones are best for business - restaurant, cafe, shop.

Also it is not necessary to forget, that for today the design decisions allow to make a call in the different form and style, instead of simply a plastic box.
