The security issue of personal dwellings or service and industrial premises was particularly acute due to the complication of the criminal situation in the country in recent years. The market immediately responded to such demand. To date, the consumer has been granted a large selection of products directly related to security.

Door locks are an integral part of this market. As we know, demand determines the proposal, and besides proposals for the purchase of products to really protect the room from unauthorized access, the risk of buying a beautiful, but absolutely useless thing remains high.

Criteria for choosing a castle

The consumer should know: not open door locks does not happen. Unfortunately, statistics from the police and the results of the tests of such products are also talking about this. Any door lock only creates an obstacle on the path of the attacker during the penetration of the desired room. In accordance with the requirements of the time, a regulatory document GOST 5089-97 was developed in the Russian Federation, which defines the requirements for the reliability of door locks. All manufacturers of these products must comply with the requirements of this document, and suppliers of locks from abroad, should conduct them testing for compliance with this GOST.

Classes of performing door locks and their characteristics

It should be noted that the parameters specified in the table are given on the basis of the experience of leading manufacturers, both in Russia and abroad and confirmed by test results in the security structures of the Ministry of Internal Affairs of the Russian Federation. In addition, the regulatory documentation determines that all locks intended for installation in the door must be accompanied by a certificate of confirmation confirming its durability and reliability. Each lock has its markup, which includes a serial number, certification sign, information about the level of resistance and reliability of the lock. So, the marking given in the passport of the sign. 3, GOST 5089-97 provides the following information to the consumer:

• The product passed the appropriate certification.
• The product is in serial or mass production.
• The product includes the 4th level of secrecy and improved security qualities.
• The product can be installed in the premises with certain values \u200b\u200bwithin itself.

In other words, purchasing a lock, note that the passport on the product was labeled like the above.

Constructive design of door locks

Castles differ in the removal mechanism:

• Suwald.

• Cylindrical.

Types of locks by installation

• Cutting door lock.

• Patch door lock.

Door locks, depending on the class of resistance to hacking are performed from materials and are equipped with additional devices, successfully opposing attackers using various methods and tools for penetration. The range of such tools is wide and may include a trivial "fomu", an autonomously working cutting or gas-plane tool.

Thus, some manufacturers use heat-resistant or wear-resistant steel, similar in their properties that are used in the manufacture of aircraft engines.

As a rule, the locks are used as components in the production of finished doors and harmoniously fit into its design.

Replacing door locks Sometimes necessary. This procedure is not as complex and under the power of any person who has minimal skills to work with a fitting and assembly tool. To the newly acquired castle, as noted above, a passport is supplied, in which the instruction should be installed.

In order to change the door lock on a new one, it is enough in the store to select an analogue of the existing and in accordance with the instruction in which it is indicated how to remove the door lock, to dismantle the old and install a new one on the old fasteners.

The task of replacing the lock is significantly complicated, if the new lock differs from the old dimensions or fastening method. With this option, it may be necessary to make changes to the design of the door, for example, the manufacture of new places of fastening, changes in the shape or number of grooves and holes for the movement of the rheel or carry the door lock.

In addition, the change in the castle will be subject to change. Such a replacement of the door lock, is fraught with the fact that the changes made to the design of the door can lead to its substantial weakening, therefore it is advisable to consult with specialists and invite those to perform work on the replacement of the castle.

Installing the castle with your own hands

Installing a mortise castle

1. Place the location of the castle. We apply the lock to the door at a distance of at least 1 m from the floor, the pencil outlines the lock boundaries, the holes for the handle, the core of the castle. From the end part I also celebrate the place for the insert.

2. Drill holes for pens and core.

In conclusion, I would like to add a few words about the safety of the premises in general. In fact, ensuring the safety of the apartment, the production room is a comprehensive task that includes not only the use of door locks of increased resistance, but also the installation of the alarm system that generates and sends an alarm signal in the case of an unauthorized access attempted.
