GENERAL CONSTRUCTION OF ELECTRONIC LOCKING SYSTEMS

UNITED TYPE OF SYSTEM
In such systems have been consolidated into a single module code and the ruling part and supplying part and conclusions are part separately. Usually, this module is mounted on the outside of the door. It raise the code to unlock the system if you type keyboard or submit an electronic key or card. This module is required to submit power, he has a direct exit management lock element. Option of some modules to have a part to interface with a computer. The advantage of such modules is the price (cheap) and easy editing (monoblok). Their main disadvantage is eliminated very easily, since management is on the outside of the door and is open to all. Another major drawback of this module is that in most cases represents power transformer network and in the absence of current system does not work. The assembly of additional emergency power supply with battery is useless as this complicated enough system and increased its price, which is comparable to distributed systems. Serial shortcoming of the single type of locking systems is easier than eliminating, at the opening of their house by not remain any traces. Aside from the said shortcomings, these systems are used by all other advantages of electronic locking systems described in the lower sections. This type of system is used mainly to control the transitional doors corridors or common rooms where security is not important.

A particular case the United systems are electronic locking systems in which all the parts - Part code governing part supplying part and locking mechanism are united in one common module. This module is mounted inside and outside door itself has no direct access to the governing center, which provides all the advantages of electronic locking systems and all mechanical failures locking systems, since the emergency opening with a mechanical key. This type of system to be installed in hotels or offices where security is of great importance.

ALLOCATED TYPE OF SYSTEM
These systems consist of three parts - the code part, locking part and a total control plant. Code has autonomous part module in the form of a reader or keyboard and mounted on the outside of the door. Serves only to link to the ruling center and any attack to take place it will not lead to unlock the system. Overall unit (control center) are managing part of supplying and interface part, as an option. Locking element is an independent module and can be one of three types locks - electromagnetic nasreshtnik, electromagnetic lock, electromechanical lock. Priority allocations type of system is that there is no direct access to locking element and not know where he is, which prevents the possibility of an attack carried out against him (unlike mechanical locks, which always visible external parts). The only visible part is the reader who has no direct connection with locking element. Another advantage is that systems are dual power - 220V and battery of 12V, making it independent of supply voltage. This type of system is extremely safe and reliable. The only blemish is more complicated installation. Use of premises with a high degree of security and protection.
