Premises such as residential, office, and industrial are equipped not only with electrical wiring, but also with low-voltage systems. Let’s find out what that is.

To maintain communication connections, a special network designed for low voltages must be established.

The entire system operates on low currents, connecting to devices that do not require high voltage and can transmit from 12 to 24 volts. When designing low-voltage systems, the comprehensive project of all communications is taken into account: electrical lines, plumbing, and especially lighting. This helps avoid unwanted intersections.

What Are Low-Voltage Engineering Systems

Another name for such networks is information networks. This is due to the direct purpose of low-voltage currents. These systems are supported by devices such as Wi-Fi, telephone lines, internet, television and radio broadcasting, etc.

In general, communication consists not only of wiring but also of adapters and technical devices, household appliances (switches, routers, hubs). They complete this chain, serving as receivers.

Another difference from power networks, besides voltage, is the relative safety for humans. Unlike the dangerous 220-volt sign, the low-voltage system cable cannot cause significant harm.

Designing Low-Voltage Systems and Requirements

High quality standards are required for communication:

Types of Low-Voltage Systems

The entire volume of communications can be divided into two large networks (conditionally):

Domestic Purpose Networks

From the name, it is apparent that they are intended for use in apartments, houses, and small organizations. Such networks have a local, enclosed space, which is serviced by specialized organizations. When connecting such networks, it is recommended to do so with the help of professionals.

Low-Voltage Domestic Systems Include:

  1. Internet. This line may have various connections, including wireless ones. However, the most reliable and uninterrupted is considered to be cable. The cable is laid underground or overhead, supplying both private sectors and multi-apartment buildings. In domestic use, it is important to connect all devices: desktop computers, laptops, routers.
  2. Television. Antennas and analog channels are gradually being replaced by modern satellite TV. But even the “dish” requires connection to the device. Currently, many homes and apartments have several televisions that can be connected from one signal source.
  3. Alarm system. The project for such a low-voltage system is carried out by specialized organizations. This is one of the most complex systems with low voltage, as it includes video surveillance, motion sensors, and notifications. Sometimes these devices immediately communicate with law enforcement agencies or security companies.
  4. Telephony. With the advent of mobile communications, the relevance of the telephone line decreases. However, in many regions of the country, especially in the private sector of small towns, the internet is still connected through a network switch and telephone.
  5. Intercom. This network is very popular. Every private house, apartment building tries to protect itself with a steel door from unwanted guests. The feature of designing an intercom is that if errors are made, the device can jam. Another frequent problem is the incorrect distribution of signals.
  6. Music systems and home theaters. Because of the abundance of devices, this equipment also requires a specialized electrical plan to avoid disrupting signals from other devices in the building (home, office, etc.).

Corporate Low-Voltage Systems

Corporate low-voltage systems include all the mentioned domestic networks, as well as:

In organizations, professionals are usually invited for the design, installation, maintenance, and timely service of low-voltage systems. For more information, you can visit here.
