Dear visitors!!!

Of course, you know that electric bells, both wired and wireless, are on sale. The wireless electric bell kit consists of a transmitter (button) and a receiver (electric bell). That is, by pressing the button, a signal is sent to the receiver of the electric call and, at the same time, an audible signal is triggered. When purchasing an electric bell (wireless, wired), the choice is ours. What kind of electric bell to buy - I will not give you such advice, but you should know that the wireless lock button may be exposed to adverse weather conditions. In this topic, we will consider a diagram for connecting an electric bell to an alternating voltage of 220V.

Call connection diagram - in the apartment

Connecting an electric bell (Fig. 1) is not difficult. The connection diagram of the call looks almost the same - in comparison, let's say, with the connection of a lamp and a single-gang switch. Of course, such a comparison looks rough, but the connection principle remains the same.

The electric bell button is connected to the phase wire. For the rest of the electrical connections, as indicated in the diagram, everything looks simple and clear.

Electric bell device

In a schematic representation of an electric bell device (Fig. 2), the following designations are given:

E-magnetic core;

K-button;

A - contact spring with a hammer;

T-adjusting screw;

B-cup bell;

U-power supply.

An electric bell, as shown in the diagram, is connected to a constant voltage. The device of the electric bell and the principle of its operation remains unchanged - both for power supply with alternating or constant voltages.

When the key (bell button) closes, in the core of the magnetic circuit (when current flows through two windings), an alternating magnetic flux is created. The magnetic flux, in turn, attracts the armature, that is, the principle of operation of the electric bell here is based on an ordinary electromagnet. The gap between the core and the armature with a contact spring is adjusted by a touching screw.

Wire connection-in junction box

You can accurately connect the wires in the junction box according to this scheme (Fig. 3). The bell is connected to an alternating voltage, that is, to the phase and neutral wires. The bell button is connected in series - on the phase wire.

That's all for now. Follow the rubric.
