​Smart LED lighting

​LED (Light Emitting Diode) lighting is a modern and economical solution for your home. Thanks to its low energy consumption, long life and minimal maintenance, it saves not only your money but also the environment.

LED bulbs provide instant and high quality lighting that can be easily adapted to different needs and spaces. Plus, they are free of harmful substances like mercury, making them a safer choice for your health and the environment.

LED strips are a part of modern electrical installations for many reasons...

  • LEDs are safer because they are powered by a small voltage up to 24V
  • LEDs are clearly more economical than other lighting sources
  • LEDs last much longer than other luminaires
  • LEDs can be easily dimmed using conventional buttons or remote controls
  • RGB or RGBW LEDs can be colour matched to suit the mood of the moment
  • programmable LEDs can be customized for breathtaking lighting effects

​energy-saving bulb 6.500 lm 8.000 h
​LED lighting 10.000 lm 25.000 h

​Although components for LED strips are commonly available in hobby shops, combining them incorrectly can have serious consequences. There is no need to worry with pre-made kits, which are sold as certified products and you can actually assemble them yourself at home.

However, caution should be taken with larger custom installations where a person with no electrical training has no idea that they can cause themselves a lot of grief.

Home camera systems

​​As part of the newly installed wiring, we also offer our clients the construction of home camera systems, which allow you to monitor your home from anywhere in the world. Camera systems have become a common part of our lives in the last decade and their contribution to the protection of property and lives is undeniable. CCTV systems are broadly divided into Analog High Definition (AHD) and Internet Protocol (IP) technology.

​Although the installation of both systems is relatively simple, it must be kept in mind that the cameras and cabling must not be placed near the lightning rod and that the length of the cabling adversely affects the supply voltage and the transmitted signal. It is worth remembering that cameras with recording must not capture public areas.

​​Structured cabling

​It is impossible to imagine a modern house without structured cabling and with its help we can transmit, for example, the Internet signal between individual routers in the home, computers, televisions or even cameras.

Structured cabling is also used extensively in the construction of smart homes, and we can also count coaxial cable for connecting antennas among structured cabling to a certain extent.

Structured cabling, especially that carrying analogue signals, is very susceptible to interference. It is therefore necessary to choose installation routes carefully during construction so that they do not coincide with power lines.

The transmitted data flows are growing unstoppably from year to year and therefore, with regard to possible interference, we select data cabling with a view to ensuring that it will still be suitable in some time.

Measurement and Control

​The term measurement and control (MC) refers to a set of sensors, thermostats, hydrostats and other devices that sense physical quantities in the house, such as humidity or temperature.

The task of the measurement and control systems is therefore to control the various technological equipment in the house based on the current climatic conditions so that the house is comfortable.

In terms of houses, MC usually means:

​control of heating

control of boiler room

control of A/C

​control of ventilation and heat recovery

control of shading​

​​Although advanced technological elements have been added to houses in the past, they were often designed as island systems that often worked against each other. A well-designed MC system should be created as an integrated system in which all elements communicate with each other.

Unless you plan to combine multiple technological devices in the house, it is economical to design MaR in a standard way.

However, if you already know that the house will be full of technology, then Loxone is the right choice.

With Loxone, it is then easy to control or automate from one central application, for example:

  • ​​the heater did not switch on at the same time as the air conditioning
  • the air conditioning or heating did not start when the windows were open
  • when the sun shines into the house, the blinds or shutters were drawn and vice versa
  • the air conditioner did not economically try to cool the room where the sun was beating down
  • in the event of strong winds, the blinds were drawn

​Power distribution for households (low voltage power systems)

​​Properly executed low-voltage power cabling (up to 1000V) is the basis of any new construction or reconstruction.

By power wiring we mean primarily electrical switchboards, socket and light circuits, fixed electrical appliances and supply lines.

Properly executed power electrical wiring is crucial to the safety and reliability of any building. Poor quality or improperly done installations can lead to serious damage, including fires, appliance failures and high repair costs.

​Therefore, the installation of power distribution systems and switchboards should always be carried out by a trained and experienced person who will ensure that all safety standards are met.

Investing in quality wiring pays off not only in terms of safety but also in terms of long-term functionality.

Our power wiring services include:

Main house wiring

​​The main house wiring can be considered to be all the wiring that runs from the cable box, through the meter box to the main house switchboard or to the dwelling switchboard.

​The electrical connection is the line from the distribution system to the junction box and is usually owned by the distribution company.

The main house line is the line from the junction box to the tap to the last meter in the building.

In family houses (i.e. maximum of three flats), it is not necessary to establish a main house line and taps to the meter can be made directly from the connection (fuse) box.

On the other hand, in apartment buildings, the main house wiring is also set up in several branches.

​The cross-section of the main house wiring (HDV) must be such that the permitted current load on the conductors is greater than the expected power consumption of all households

A cross-section for one to three households is usually sufficient for a Cu 4 x 10 mm2 or Cu 4 x 16 mm2 cable.However, never forget that regardless of the current load, the minimum cross-section of the PEN conductor must be at least 10 mm2 in copper or 16mm2 in aluminium.

​Earthing/Grounding system

​​The earth is a very important element in electricity because it is through the earth that currents from the wiring are returned to the substation or atmospheric surges from storms or even lightning itself are discharged into the earth.

Grounding is, in simple terms, a kind of transition bridge between the wiring and the earth itself and should provide a sufficiently clear path for currents to reach the earth as easily as possible - or low resistance.

The importance of earthing is further discussed in the article "Why it is necessary to earth the point of division of the PEN conductor into PE and N conductors."

Unfortunately, not all soils are well conductive and, for example, such dry stones do not conduct current almost at all. The worse the soil conducts current, the larger the transition bridge must be = the larger the contact area with the ground must be.

​Earthing is most often performed by...

  • ​grounding galvanized strips or wires
  • grounding galvanised rods
  • grounding foundation nets

​​It is therefore necessary to pay particular attention to the correct grounding craftsmanship, because the grounding system is usually unrepairable in the future. Very often we encounter situations,

  • ​​​when the size of the earthing system does not correspond to the soil resistivity,
  • when the connections are not double-wired or insulated against moisture,
  • where the transitions of the earthing system between materials are not treated with corrosion protection.

​Over time, these problems can make it so difficult for currents to pass easily into the ground that the protective elements cease to function or lightning seeks a path of less resistance through the building structure.

Before designing the earthing system, it is recommended to measure the soil resistivity at the building site and design a suitable solution based on the measured values. It is then necessary to make sure that the proposed solution is also implemented correctly, which certainly does not mean throwing the grounding strip on the bottom of the excavation.
