Battery-powered calls: characteristics, installation and selection features

Battery powered bells can operate independently of the mains power supply. But in order to enjoy this advantage, you must first choose the right model, and then correctly put it. We'll have to figure out for a start with a specific type of device.

The widespread opinion that this device only "rings in different ways" is completely wrong. More recently, some 30 years ago, it was possible to buy either a simple wired bell, or even a simplified mechanical version. Now the situation has changed dramatically, and even ordinary electromechanical devices can have a variety of melodies... There is a significant difference in design, thanks to which you can choose a model to your liking for any interior.

The electromechanical device works in a very simple way. When someone presses the button, an electric current is supplied to the coil. Under its influence, the electromagnet sets the percussion mechanism in motion. The contact between the moving hammer and the plate creates the characteristic sound. The larger the resonator, the stronger the sound produced.

But more and more often there are apartment calls with an electronic element base. In them, not a plate and a hammer are responsible for receiving sound, but a special electronic circuit. It allows you to create a wide variety of melodies and, in addition, vary the volume much more flexibly. It will even be possible to change the sound of the signal if the old "trills" have ceased to be liked. Both electromechanical and electronic device types:

• work very reliably;

• serve for a long time;

• are relatively inexpensive.

The battery-powered wireless chime is mainly used by summer residents and owners of suburban housing. Nobody bothers, of course, to put such a device in the apartment. However, there he will not reveal his main advantage - the ability to work at a great distance from the button. This distance in modern models can be up to 80-100 m (in ideal reception conditions).

The radio call is characterized by the fact that only the button receives energy from the batteries. The main part of the device needs to be connected to the mains. Hybrids work well, but their features must be taken into account during installation and subsequent use. The remote model can work not only using a conventional radio transmitter, but also using Wi-Fi modules. True, the ability to control from a smartphone is greatly overshadowed by the high probability of jamming.

Another modern innovation is a call with a motion sensor. Thanks to him, people do not even have to press a button - the device will start making a sound when they are still on the way to the door. A similar technique is able to respond to a person leaving the street. True, this option is useful mainly for retail outlets, catering and warehouses. But the built-in video camera will be attractive for private use as well.

With its help you can:

• conduct conversations with guests without opening doors;

• control the landing or courtyard (area in front of the gate);

• replace a full-fledged video surveillance system.

A typical video call package includes:

• cable or wireless communication channel;

• elements of autonomous power supply;

• overhead panel;

• control panel with a screen.

It is necessary to consider the difference between apartment and street models.Any device can be mounted inside the house. On the street, wireless models are installed in most cases. A very important role is played by the use of a moisture-proof coating. It is also necessary to assess the resistance of the equipment to temperature effects and changes in humidity.

The suitability of a device for installation in an apartment or house does not mean that this particular model is perfect. The vast majority of people will enjoy a one-button call with multiple receivers. They are placed where they think is necessary, and therefore you can hear the call anywhere: in the barn, in the garage, in different parts of the house. For the elderly and other users with hearing impairments, it is worth choosing call models with light indication. You can focus on the ratings, but you must pay attention primarily to your own needs.

The cost of calls varies greatly. The price for devices with audio communication and video cameras can exceed 10 thousand rubles. Smart calls are those that are also capable of sending alerts to smartphones. It is better to choose such models from well-known manufacturers. As for the choice in favor of budgetary or expensive models, you will have to make it taking into account your well-being.

Such partitions prove to be an almost insurmountable barrier to the radio signal. Experts advise to initially get acquainted with the set of available melodies and immediately check whether they are suitable or not.

Models are popular:

• SPACE KOC_AG307C2;

• MELODIKA B530;

• FERON 23685.

Before starting work, you need to prepare an electrical circuit for a specific room or use a ready-made circuit. In newly built apartments, standard electrical wiring is most common. Even if the model is not a hybrid, but purely battery-powered, it is still impossible to start installation without an electrical circuit. This can lead to dire consequences.

Installing a wireless bell means attaching the button to the wall or door jamb. According to the type of base, it must be mounted on self-tapping screws or dowels. Through the standard mounting holes, mark and drill the wall or doorframe. The batteries are placed in the screwed-on button. On a wooden base, it is fixed with self-tapping screws.

After the battery is changed in the call, it usually enters the search mode. In order not to connect unwanted buttons, you do not need to press anything except the main call button within 15 seconds after pressing it.

Replacing a battery that has run out does not cause any problems. Even usually there is no need to read the instructions additionally - everything is already clear what to do; most often on cheap models, latches are used. Complaints often arise that the batteries run out quickly. The solution to the problem is to upgrade the device. It is necessary, however, to feed the main unit (all the time working in anticipation of reception) from the network.

First, connect the power supply of the board and the speaker. Then, a voltage of at least 3 V and not higher than 4.5 V is applied to a new single contact. Important: this section of the power grid must be equipped with a voltage stabilizer. Otherwise, any jump can destroy the device.

If the bell works intermittently, you need to check the batteries, replace them as necessary. Sometimes a simple check of the correct installation and signal transmission conditions helps. It is worthwhile to conduct such a test: bring the receiver and the button as close as possible, removing all obstacles, and try to press. If problems remain, then the blocks themselves will have to be changed. The complete inoperability of the call is eliminated in about the same way; sometimes it helps to reassign the buttons to the receiver, and in case of failure, you will have to contact the specialists.
