Calls on batteries can work independently of the mains. But to enjoy this advantage, you must first choose the model, and then correctly put it. We will have to understand to start and with a specific type of device.
The problem is that this device only “rings to different frets” is completely incorrect. More recently, some 30 years ago, it was possible to buy or a simple wired call, or simplified mechanical option at all. Now the situation has changed dramatically, and Even conventional 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 taste in any interior.
The electromechanical device works very simply. When someone presses a button, an electric current is supplied to the coil. Under its impact, the electromagnet leads the impact mechanism. Contact moving hammer and plates just creates a characteristic sound. The greater the resonator, the stronger the dry sound.
But more and more opportunized apartment calls with an electronic elementary base. In them, no plate and hammer correspond to the sound, but a special electronic circuit. It allows you to create a variety of melodies and in addition to vary the volume of much more flexible. It can even be changed the sound of the signal if the previous “TRELL” stopped like. And electromechanical, and electronic device types:
work very reliably;
serve for a long time;
It is relatively inexpensive.
Wireless bell on batteries is mainly used by dacms and country housing owners. No one bothers, of course, put such a device and in the apartment. However, there he will not reveal its main advantage – the ability to work at a high distance from the button. This distance in modern models can be up to 80-100 m (in ideal reception conditions).
In reality, of course, noise is much more – but the signal transmission distance is usually less.
Radio calls is characterized by the fact that only the button receives the energy from the battery. The main part of the device needs to be connected to the mains. Hybrids work well, but their features should be considered when installing and subsequent use. The remote model can work not only at the expense of a regular radio transmitter, but also with Wi-Fi modules. True, the ability to control with a smartphone is strongly overshadowed by a high probability of targeting interference.
Another modern innovation is a call with a motion sensor. Thanks to him, people do not even need to press the button – the device will begin to publish sound when they are still on the way to the door. Such technique can respond and care for the street. True, this option is useful mainly for trading places, catering and warehouses. But the built-in camcorder will be attractive for private use.
With it, you can:
conduct conversations with guests without opening doors;
control the staircase or courtyard (section in front of the gate);
Replace a full-fledged video surveillance system.
A typical video call package includes:
cable or wireless communication channel;
offline power elements;
Screen control panel.
It is necessary to take into account the difference between apartment and street models. Inside the house you can mount any device. On the street put wireless models in most cases. The use of moisture protection coating plays a very important role. It is also necessary to evaluate the durability of the equipment to temperature effects and moisture drops.
Tips for choosing
The suitability of the device for installation in an apartment or house does not mean at all that this model is perfect for. The overwhelming majority of people will like the call with one button and several receivers. They put them where they consider it 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 a weak hearing, you should choose call models that have light indication. You can focus on ratings, but you need to pay attention primarily to your own needs.
Call cost varies very strongly. The price of devices with audit and video cameras may exceed 10 thousand rubles. “Smart” calls consider those who are also able to send alerts to smartphones. Such models are better to choose from well-known manufacturers. As for the choice in favor of budgetary or expensive models, it will have to make it taking into account its well-being.
IMPORTANT: The aesthetic characteristics of the call should be taken into account. He must fit into the style and color of the apartment or at home. Select wireless calls for buildings with thick brick, stone walls are inappropriate.
Such partitions are almost an insurmountable barrier for a radio signal. Experts advise initially get acquainted with the set of available melodies and immediately check, they are suitable or not.

Installation and operation
Before starting work, you need to prepare the electrical scheme of a particular room or use the finished scheme. In the newly built apartments, the electrical wiring of the standard sample is most often paved. Even if the model is not a hybrid, but a purely working on batteries, it is still impossible to install without an electrical circuit. This can lead to sad consequences.
Installing a wireless call implies the mounting of the button on the wall or on the door of the door. According to the type of reason, it is necessary to mount it on the self-tapping screws or a dowel. Through the regular mounting holes make the mark and drill the wall or door jamb. In the screw button put power elements. On a wooden base, she is fixed with self-draws.
After the call will change the battery, it usually goes into search mode. In order not to connect the unwanted buttons, you do not need to apply to anything, except for the main call button, for 15 seconds after pressing it.
Reset binding memory to buttons, removing power items. Additional binding is made after clicking on the special code selection button. After that, there are 15 seconds by pressing the optional call button.
Replacing the battery that sat down does not cause any problems. Even usually there is no need to read the instructions additionally – everything is clear what to do; Most often on cheap models use latches. Complaints often arise that batteries quickly sit down. The solution to the problem is to upgrade the device. Calculate, however, to feed the main unit (all the time it is waiting for the reception) from the network.
First connect the power supply and dynamics. Then fed to a new single contact voltage not lower than 3 V and not higher than 4.5 V. IMPORTANT: This section of the power grid must be supplied to supply voltage stabilizer. Otherwise, any of his jump can destroy the device.
If the call works with interruptions, you need to check the batteries, as you need to replace them. Sometimes it helps a simple checking of the correctness of their installation and signal transmission conditions. It is worth conducting such a test: browse the receiver and the button as much as possible by removing all obstacles, and try to click. If there are problems then, the blocks themselves will have to change. The complete failure of the call is eliminated about the same; Sometimes it helps renovate buttons to the receiver, and with failure – you have to contact the specialists.
