ENCYCLOPEDIA OF RADIO ELECTRONICS AND ELECTRICAL ENGINEERING
Security systems. Encyclopedia of radio electronics and electrical engineering
Encyclopedia of radio electronics and electrical engineering / Security devices and object signaling It has always been common for a person to protect himself, his home and his loved ones, his property from possible danger. To do this, he used all available methods and methods. At first, these were the simplest means of physical protection, over time they were transformed into burglar alarms, and now modern multifunctional security systems work for a person and effectively cope with their security tasks. When buying an apartment or a house, opening a store, organizing his own company, a person is faced with the problem of organizing security. He is faced with the task of ensuring the proper level of protection of his values. In solving this problem, everyone turns, first of all, to his own life experience. Based on it, taking into account their field of activity and business contacts, subjective and objective assessments of the likelihood of a threat are given. When choosing security means, such important factors as the location of the object in need of protection and the crime situation in this area must be taken into account. Along with the current commercial enterprises and banks, consumers of security systems are also private individuals: entrepreneurs, farmers who own shops, cottages, households, etc. An increasing number of Russian merchants, in order to protect their business from unwanted interference from competitors and criminal structures resort to means of the security system. This is evidenced by the high demand for such equipment. For example, a few years ago, video intercoms for many of our compatriots seemed to be something exotic and inaccessible. Now they are in great demand, they are offered by many manufacturing companies. Along with an apartment video intercom, which is a simple system and is not so expensive, there are also security systems used to protect private houses or cottage settlements. Such devices, in terms of their technical complexity, do not lag behind the systems that are used to protect serious organizations. When buying them, the consumer inevitably faces the conclusion of an agreement for the installation of equipment. To protect against low-quality products, there is a mandatory state certification of security systems. For the most effective protection of the object, it is necessary to use means that meet certain requirements and have special certificate. In Russia, for security devices, the State Standard of Russia operates, compliance with which must be confirmed by certificates. Certificates are issued at the Certification Center for fire and security alarm equipment of the Main Directorate of Private Security of the Ministry of Internal Affairs of the Russian Federation (CSA OPS of the GUVO of the Ministry of Internal Affairs of the Russian Federation).
GOST of Russia takes into account the peculiarities of the use of such equipment in our country and, in contrast to Western standards, assumes more stringent requirements for some positions. On equipment that has passed certification, there must be a mark corresponding to certification (Fig. 106).
Since a large number of leading security companies that supply their products to the Russian market are American, US standards are of interest. The protective equipment produced there must comply with the requirements of UL (Underwriter Laboratories Inc). Equipment built to these specifications carries the UL mark (Figure 107). There are international standards that certify equipment that has passed various stages of production with certain requirements imposed on it (Fig. 108).
Gosstandart of Russia constantly keeps a general record of funds with various certificates. In our country, all security equipment must first of all comply with Russian standards. Having determined the required level of protection and having acquired the necessary technical means of protection, it is very important to install them reliably and correctly. Otherwise, the costs will be unjustified, since inefficient devices make practically unprotected what needs to be protected from a possible threat. The presence of a weak lock, a fragile door, as well as an alarm system that does not meet the necessary requirements, contribute to the penetration of an intruder into the object and theft of valuables. Today, the task of protecting a particular object, as a rule, is solved in a complex way. Alarm systems are installed, first of all, taking into account such factors as ensuring reliability, ease of use and the possibility of upgrading the system. Particular attention is paid to fire safety, since, according to statistics, there are much more losses from fires than from thefts. But, despite this, many people try not to think about possible troubles. Hoping for the Russian "maybe", they will not worry once again about reliable protection and thereby endanger not only property, but also their own health. In some cases, the lack of reliable security measures can cost lives - your own and loved ones. Assessing the level of costs for additional protective devices or the modernization of old ones, it must be said that these are disproportionately small funds in comparison with the damage from a single break-in or fire. When equipping the premises with security systems, you should contact the specialists, since only they can perform installation work with high quality. Installed security devices must always be used correctly, which may require prior training. It is worth spending some time on this - thus you can avoid various troubles and upheavals.
