Most of us can not imagine life without devices, simplifying household chores – a food processor, microwave, washing machine and dishwasher, fridge and other necessary equipment. Our crowded housing items that make life better. You know that among all of them have in common? That's right: electricity. So what is it like to electricity? It is odorless and invisible, is the result of movement negatively charged particles on a closed circuit. We often do not pay attention to it in everyday life, but if the current suddenly ceases to run on the wire, all useful and necessary things we will turn into a pile of scrap metal. In fact, anyone remember what happens in the apartment when the light goes out for several hours and remembers that impotence, which he feels – pitch-darkness, nothing more. And all this just because of one thing – the lack of electricity. It is not easy to imagine, but there were times when the electricity does not yet exist, and people used to light the candles of their homes.

It was beautiful, but it is not safe, and many lost their homes due to careless handling of fire. Only in 1733 the French scholar Du Fay discovered negatively and positively charged particles, the effect of which was later called 'electricity'. But the electrons (negatively charged particles) are not move through the wires themselves – to ensure that they have moved away, they need a driving force. It was such a force and is due to power generators. Then 'revived' electrons, crossing the wires, are transformers, and then – straight into our house. Even though its usefulness and indispensability, with electricity trifled with. For this reason, every person must learn the techniques of safe use electricity and to prevent their violation. One of the major hazards that can cause a person to death harm – an electric shock.

Electrical shock can occur when a person touches the bare wire under tension. Wire without insulation – this is a gross violation. Isolation or a complete replacement of the wiring – this is a solution that can protect people from injury and save lives. The main methods designed to protect people from the danger of electrical shock: prevention of damage to the network, the division of power grids, grounding, insulation of bare wires. Electrical insulation – one of the most effective methods of protection against electric shock. It consists in winding wire layer of dielectric material. Isolation may be different, but the most effective – Reinforced insulation, made of several layers of dielectric material. Only such insulation can guarantee that a random contact with live element will not lead to electric shock. Moreover, anyone worth remembering that all electrical work must be carried out only specialist. Electric wiring Kiev will perform, carry out the separation too extensive electrical network, isolating it and thus ensure the safety of your home. Today, electrical service can afford any, so calling an electrician at home – critical decision a person who care about their safety and security of their loved ones.

Periodically turning off the heating element and including that in turn supports desired temperature in the room. Equipped with some instances of a fan for fast heat in the room. In addition, the heaters have a good security system: shut down, if there is an obstacle to Release the air in the fall, and in contact with the heating element outside predmetov.Teplovye fan heaters, as heaters are available with closed and open spiral. In order to quickly warm room, using forced air circulation. Accelerate the heat transfer of air fans axial (eg, fans Innovent firms) that do not require large heating elements and as a consequence of this are small. When you save power and at the same time opportunities for small size is an open spiral, which become heated to high temperatures.

Large temperature gradients, convection currents in premises, all fees for heating rate and the compactness of the unit. Available in models with removable filter, which is responsible for the misses on a hot dust spiral. Many heaters have multiple speeds and heating levels. It is also possible to use the device in automatic mode, thanks to the thermostat. Overheating sensor is used to disconnect from the network in case of critical temperature, which is responsible security appliance.

There are models with rotation and tilt housing, with stand and legs. In summer, turn off the heating if it is possible to use as a regular ventilyator.Teplovye guns Heat guns, these are the same heaters, only great power. They are used to heat large buildings: sheds, greenhouses, garages, and are used outdoors. Heat gun with a closed coil can be used indoors without ventilation or poor. Produced heat gun and an open spiral. Required electrical network capable of supporting a large capacity. Such models are not recommended for use in areas where people are a lot of time. Also, the gun can be equipped with a thermostat to protect against damage, overheating and vibratsiy.Teplovye curtains Air curtains on the basis of his work similar to the heat guns and fan heaters. Due to the flow of narrowcasting air creates a barrier to the penetration of cold air from the street. The veil also protects the building from falling into the smoke, dust, insects, along with air and various zapahov.Maslyanye Radiators Oil Coolers are not very high temperature of its surface, up to 80 degrees. As a result, do not dry the air and on this parameter are in first place among all the heaters, but have very large dimensions. So before you do choice in favor of the oil cooler, consider its location. Oil heaters have different design and capacity. Electrical Safety – off overheating and overturning. As with all heaters, has heat setting – a timer that allows you to work the radiator program.

'My home – my castle' – is a saying in the course of the English. Surely, the world would find a man who would not want to protect their "nest" the most reliably. During the existence of mankind people have come up with a lot of ways of Defence housing. This complex system of locks and sturdy metal doors, fences and inaccessible. However, without doubt, to date, remain the most advanced technical means of, namely the perimeter alarm. Perimeter security systems are distinguished by the fact that given an opportunity to fix the fact of threats before they enter the house. Often, they are mounted to the fence that protects your possessions. Perimeter security signaling is highly sensitive and, therefore, can not guarantee that an attacker will be noticed and neutralized in time.

However, some specific means of detection should be chosen? For a start, it should be say that all means of detection can be divided into species such as radio-wave detector, vibration system, infrared sensor and radioluchevaya system. Vibration sensor, in turn, pinpoint certain sound vibrations. A special system distinguishes the background noise, and vibration alarm detector is triggered only when an attacker trying to penetrate the zascheschennuyu territory. The detectors are infrared security also deserve your attention. There are several types of such signaling, but the most famous are the detectors are passive infrared sensor which reacts to heat, that is, animals and people. That relatively radioluchevyh detectors, then the principle of their operation is based on the processing of microwave signals. This kind of alarm system is designed to determine the motion of an object.

Consequently, the sensors are mounted radioluchevye so that alleged robber they could "see". Usually they can be found on special poles or fences, buildings. Detectors are made radio-wave security of wires between them formed a field. If an object falls into the beyond the field, the system will be served an alarm signal. Now you know enough to find the right system for you, good luck!
