Connecting an electric call in an apartment, house

Installing and replacing a doorbell is the most difficult task. If you can work with an electrician even a little, you can do it. Next, we will talk about how to connect a bell in an apartment, house - wired and wireless.

Types of apartment calls

Electric apartment bells by connection method are of two types - wired and wireless. Wired ones are connected to a 220 V network, there are models operating from a low voltage of 12 V. They are called wired because the bell button and the indoor unit must be connected with wires.

Wired calls - the button and the indoor unit must be connected by wires

In wireless electric calls, the button and the indoor unit are not physically connected. They have a miniature transmitter (in the button) and a receiver (in the indoor unit). They communicate with each other at some frequency. There are two types of power supply for wireless calls:

• The indoor unit and button are battery operated.
• The button is powered by batteries, the indoor unit is powered by a 220 V network. Moreover, there are two ways to implement indoor units: with a standard connection to the terminals with wires and with installation in an outlet. In the latter version, there is a conventional electrical plug on the body. In this case, it is very simple to connect the bell in the apartment and in the house: you need to install the indoor unit in the socket, screw the button on the entrance / gate and insert the battery.

Wireless calls with the connection of the indoor unit through the socket

As already mentioned, in the wireless version, the button and the electric bell "communicate" with each other through signals. Signals can be transmitted in analog or digital form. More reliable digital signal transmission - less distortion. In addition, such models have the ability to change the channel through which the transmission / reception takes place. When transmitting an analog signal, this is not possible. Why is that bad? Call range - 100 m and more. And if there is some device in this zone that operates on the same frequency (bell or other), your receiver can pick up its signals. In this case, there are false positives.

Also, doorbells are not divided between apartment and street. They differ in that for those that are installed on the street, the buttons are made sealed and dustproof. In addition, it is recommended to install them under a small visor - there will be less problems.

Connecting wired electric bells

As mentioned earlier, wired doorbells differ in that the button and the indoor unit must be connected with wires. Connection diagram through the junction box in the photo below.

Electric doorbell wiring diagram

A phase wire is put on the button, from the second terminal of the bell it goes to one of the wires of the indoor unit. On the second remaining free wire we connect "zero" (subject to color coding it is usually blue or light blue) of the junction box. If the indoor unit has a grounding terminal, a yellow-green conductor is connected to it, which should also come from the junction box. If there is no such terminal, but there is a conductor, it is isolated.

The difficulty of connecting an apartment bell is that the wires must be passed through the wall. Sometimes this is too inconvenient, then the hole is made near the door frame.

If this connection seems too complicated for you, look for models of wired calls with an internal block that plugs into an outlet. There are some. Example in the photo.

Everyone knows how to connect a bell in an apartment if it has an electric plug. In this case, you only need to pull the wire connecting the two blocks through the wall. To do this, you will need to disconnect it from one of the parts, pull it through the prepared hole, then connect the wires in place.

Connecting and powering wireless calls

First, we will focus on those models whose internal blocks are connected to a 220 V network. If there is a plug on the case, you know exactly what to do. If there is no plug, but there are two wires, connect two wires to them that come from the junction box. If there are three wires, insulate the yellow-green, and connect the blue and the second (maybe brown, red, black, white, etc., but definitely not green and not yellow-green).

The design can be very different

If both units are powered by batteries

There are no problems with how to connect a bell in an apartment or house if both units are powered by batteries. Just in a suitable place in the house you drive in a nail or tighten the screw to which you attach the indoor unit, put the batteries. You do the same with the button, but you mount it outside - near the door or wicket. In order to secure the button, the case must be opened (there may be small screws, but usually you just need to pry the case with a screwdriver).

There are several mounting holes on the back wall. Fasten the back cover with screws or dowels (depending on the material), then install the batteries and close the cover. This completes the wireless call connection.

This is what the wireless call button will look like when disassembled.

How to provide power to the wireless button in cold weather

Wireless calls are good for everyone, except that there can be problems in winter: some types of batteries freeze and stop working. They have to be changed every 10-15 days. It is very inconvenient, as it is difficult to understand that the call has stopped working due to a dead battery. You can get rid of this situation in the following ways:

• Use lithium batteries. They are not afraid of frost - they can work without problems up to a temperature of -30 ° C.
• But batteries of this type for 9 V or 12 V are simply unrealistic to find. They are almost not on sale. Outputs:
  • Look for doorbells with buttons that have AA or AAA batteries. There are such lithium ones.
  • In some sealed container, connect several batteries of a smaller value so that they give the desired voltage at the output. Fix this container on the inside of the fence, remove the wires and supply power to the button.
    

    In winter, it is important to provide power

  • Find a lead acid battery that supplies the correct voltage. They can be found in security alarm companies. There they are not afraid of frost, there are different denominations.
• Put the batteries in the house, pull the wires to the button.

By modifying the system in any of the proposed ways, you will have much less problems with the power supply of the bell button on the street. Now you know not only how to connect a bell in an apartment and on the street, but also how to ensure its operation in cold weather.

Non-standard equipment

In some cases, two buttons or two bell blocks are required. If two buttons are needed, they are connected in parallel.

How to connect two buttons to one doorbell

In practice, this means that the phase comes to the first button, and a wire is connected to the same contact that goes to the second button. From the second contact of button # 2, the conductor enters the free contact of button # 1, and then goes to the doorbell.

It is advisable to find the wire connecting the two buttons in the same color as that comes from the junction box. It is possible and other, but not blue or yellow-green. Everything, you know how to connect a bell in an apartment with two buttons.

In other situations, you need to connect two calls. This is often necessary when installing an electric doorbell in a private house.For example, one in the house, the second on the street or on different floors, in two different wings of the house, in summer kitchen... In general, there are many options.

Among the wireless doorbells there are such kits - in two bells and they are tuned to the same frequency, so you just need to install them in the right places. You will have to mess with the wired ones - pull the wires. In this case, calls are connected in parallel.

how to connect a call in an apartment or in a house with two calls

The electrical connection is made in the same way as described above. The phase from the button goes to one call, from it goes to the second. A neutral wire from the junction box is connected to the free contacts of one and the other bell.
