A. Rudnitsky, E. Abishev A. SAHIBZADINOV, A. Zhukov Q: What should defend themselves? Answer: Three types of threats. Threat of a criminal nature - larceny, robbery, robbery, arson, vandalism, etc. Threat of man-made - an accident in the water, heat, fire, etc. Threats to the natural character - lightning, hurricanes, floods, etc. Question: Under what conditions is advantageous to use perimeter security system? Answer: Such systems are useful for the protection of suburban lawns is not less than 0,5 ha in combination with closed-circuit television in the mandatory presence at the site of a permanent post. Otherwise, what is the use of electronic detectors that signal the fact of penetration of foreign territory, if the signal is nobody reacts! Q: How do the infrared detectors protect the site? Answer: The active infrared detectors triggered by interruption of invisible infrared beam. This is the most acceptable and relatively inexpensive types of sensors for perimeter protection infield. One pair of sensors can protect the area up to 200 m is generally used to protect the site from the penetration of someone outside the presence of hard concrete or brick fence. The device is controlled so that makes it possible to detect the offender, but to miss small animals and birds. Addition to the alarm system is a system of closed circuit television, allows quickly observe the territory on the screen and keep a continuous recording on a VCR. Q: What are the advantages of external motion sensors? Answer: The standard set of internal alarm sensors: magnetic contact sensors, sensors that react to the destruction of the glass, the internal infrared motion sensors, etc., allowing the attacker to discover when he got into the house. Such a scenario may not always ensure the safety of the homeowner. Experience has shown that the best option defense system for a country house is to create a buffer zone around the perimeter of the building width of 2 - 5 m with infrared motion sensors mounted on the outer walls of the building. This allows us to detect an attacker to penetrate into the house. Q: What is the principle of vibration sensors and triboelectric types? Answer: In such systems as sensor uses a special cable, which is sensitive to mechanical vibration or shocks, are laid along the fence area. One sensor monitors up to 250 m of the perimeter of the site. Restrictions on the use of such systems is the necessity of the exclusion zone along the fence a few meters in width. Otherwise, the chances of false alarms. Question: Can I rely on the electronic security system? Answer: Hoping for a system of protection possible. But should not be complacent. Because the failure of simple rules can make useless all your efforts and costs. Here are some of those rules: do not leave the house keys in the keyhole, and even more so, we should not hide under the rug, or other "secluded" spot that you make it easier intruder penetration into your home, explain to children the rules of conduct with strangers constantly warned them about the inadmissibility of giving the keys and open the door to strangers under any pretext, if lost or stolen keys should be as soon as possible to replace the locks or, if it allows the construction of the castle, its mechanism of secrecy (cylinder engine), doors must be permanently in a locked state, even if you're out for a smoke, went in for a minute to a neighbor or have decided to take out the trash, do not open the door, without seeing okolodvernoe space in the peephole. All entrance doors in the home should be equipped with door viewers, watch for proper lighting around your home, it is necessary to negotiate with a neighbor about alternate care for shelter, such caution will not be redundant; leave the house in your absence only those people whom you and your family know well. Think about security of the home, how to store values, the organization works with confidential information can only you, as the system of organizational measures, figuratively speaking, is the primary key to the lock that protects your property. Q: What are the grid should be placed on doors and windows? Answer: Not everyone knows that double lever shears, which are sold in almost every shop "Tools", you can effortlessly snack steel rod with a diameter of 10 mm. Therefore, the choice of the lattice should be preferred frameless, which walled rods directly into a wall at a depth of not less than 80 mm, the distance between the bars of less than 150 mm and thickness of the rod is not less than 16 mm. Figure lattice can be arbitrary, but most have the protections of the lattice, the bars are located a diamond or a cross and cooked in every crossroads. For the protection of window openings, except for arrays can be used by special panels and shutters. Such protection is particularly effective for country houses, cottages, cabins, in which long-term (seasonal), there are no bosses. Wooden shutters or panels of the boards shall be completely filled canvases and a minimum thickness of 40 mm. Perhaps their execution of the boards or plywood 12 mm thick padding on both sides of sheet steel not less than 0,6 mm. To protect the window and door openings can be used as metal shutters and blinds. Q: What are the self-adhesive window film? Response: Protective film - a multi-layered system that combines a durable, pressure-sensitive adhesive and resilient polystyrene layer. It is glued directly onto the window glass and is both colorless (transparent) and a tinted (darkened) version. Book a (strengthening) of the film serve as a shield, which prevents the glass to crumble into pieces and allows you to easily and freely enter the premises. Deposited on the inner side of the window glass, they create a protective layer that holds the glass even with a very strong impact. Tests showed that the ordinary glass 4 mm thick, installed on it the film thickness 112 microns can withstand the pressure energy of 20.4 J, which is equivalent to the impact of 1 kg stone thrown through the window from a distance of 2 m. The protective properties of shutters Question: How effective is the use of roller shutters as a means of protection? Answer: I must say that "common thief" who tend to climb in the absence of the owners of dachas and country homes, try not to mess with a system of protective shutters. How to deal with the lattice in case of burglary - is understandable. In this age of technology when invented the mechanical, hydraulic and other clippers, she just bites. But what about the shutters - here is unclear. Their bare hands just do not open, "kurochit" their crowbar or crowbar - the noise a lot done, clippers not bite - not the design. For "opening" is good only saw - "Bulgarian", as would have saw through quite long. But not every fan posharit on other people's dachas carries with him a chainsaw, and even necessary for this saw power (220 volts) with an also did not bring it. That and trying to bypass the windows with protective shutters side. There are already examples such as standing in a row of houses cracked namely, those windows are not protected by shutters. Of course, from "professionals" to protect themselves is difficult, but from the "petty thugs" - it is quite reliable protection. During certification testing protective shutters successfully resisted and resist the attempts of opening with an ax, hammer, drill. For more security shutters can be equipped with additional mechanical locking devices. Against lifting the outside - Hand beams, transom locks, as well as the guide bar reinforced structures. Q: What other functions except defense, perform shutters? And by the way, from its name - "shutters"? Answer: "Shutters" - a purely Russian name, as it is not surprising. This title is no longer in any country. In the West adopted a different name - "roller" (the English word ROLLETS). In Russia, has long been outside the shuttered windows. Apparently, the mixing of foreign and Russian words, and was born peculiar to Russian name - "shutters." Shutters can be called a protective shutters. But functionally, they are designed not only to protect against intruders. They possess and thermal protection, and sound insulation (noise) properties are protected from exposure to precipitation, and, of course, protected from prying eyes. Q: What are the blinds safer: built-in window opening, or "overhead"? Answer: The problem in terms of protection is generally not a security shutters themselves, and that customers are treated too late. Apply to the firm when the house is already built, installed windows and exterior trim begins at home. As a result, installed shutters on the outside of the window, not in the window opening. The degree of protection of such shutters are somewhat lower than the "built". Approach to installing roller shutters should be somewhat different. They just need to lay the project. Shutters and looked much more spectacular, and the reliability of their much higher. Overhead roller blinds have the "thin" place - the guides. They can, and bend, and even pull away from the wall (though with great effort). Built-in (almost "bricked" the masonry or concrete) may turn out a guide or can not bend, it will have to dismantle the wall. Get to them you only if the blinds are raised. And this happens only when the owners home. Q: Can the shutters to reduce noise in a city apartment? Answer: The coefficient of sound insulation roller shutters R = 37 dB. In this case, we can safely say that the lowered blinds of about 20% lower noise road. We think that this is especially true for the inner cities, whose windows overlook the busy street. But when you install shutters on the homes is a technical difficulty. When installing the shutters to the height of the third floor using the appropriate length of the ladder. But the above will be mounted, descended from the roof, and for this need assemblers, "climbers." Q: What are the advantages of remote control roller shutters? Answer: This effect is primarily in comfort. You sit and watch TV, but the window just before sunset, the room gets direct sunlight. Without leaving your favorite chair, you can omit the blinds to the desired height. As the remote control shutters used mainly radio control. Such remote control may be either single-channel and multichannel. Multichannel allows one remote to control several shutters. This will raise and lower them simultaneously, rather than running around from room to room from one window to another, dropping them one by one. Q: Can I install a control mechanism roller shutter timer? Answer: Yes, you can add the electromechanical circuit roller shutters timer. For example, at 8 am on all the blinds in the house will rise at the same time, and looked into the opened window, the sun wish the owners of the "good morning" (but sleep up to 8 hours in the morning will not interfere). If you add a light sensor, the closer to noon when the sun is the brightest, shutters will lower a little, limiting the sunlight indoors. Q: How secure garage doors, rolling shutters? Answer: More and more car owners opt for a gate-shutters. The reasons for this is enough: increased protection from hacking, optimal comfort, long service life and visual appeal. They can be easily mounted to existing garages. In the coiled state garage doors are a decorative aluminum box. The color of this box is selected in the color of the gates themselves. Q: What is the degree of protection signal for opening the automatic garage door? Answer: The degree of protection radioklyucha to open garage door is the automotive anti-theft system. Of course, any radio signal, a signal off the anti-theft system and a signal to open garage door, you can "scan" and then play, but this requires a special high-class equipment and an appropriate level of technical expertise. But from an ordinary burglar, not fitted with equipment, the extent of protection is sufficient. Q: What about the automatic shutters and garage doors that use electric, if a power failure? A: In case of power failure in the network they must be equipped with hinged crank handle (emergency manual opening). Have to spend about five minutes. Of course, have a little work to do to twist the handle actuator arms, but you'll be able to open and close the gate again, or shutters. Security doors Question: How reliable as to protect the house from the metal door? Answer: Generally, a metal door is appreciated not only the ability to reliably protect the house, but a noble appearance. Although secure than a metal door, yet come up with - only the metal stand the onslaught of the professional hacker. But you should not have illusions - even the best metal door does not guarantee complete security. Favorite tool crackers - an angle grinder ("Bulgarian") with a disc diameter of 230 millimeters and a capacity of not less than 2 kW - cuts almost all ... The question is how long the attacker will spend on this procedure? The answer is: the stronger the door - the more it will be straining, and the more time - the less willing a thief to mess with it ... Q: What is the metal door is better: ready styles or made to order? Answer: The Pluses and minuses are in both versions. The finished door can install on the same day. This is useful if, for example, you are robbed, broke the old one, or someone threatened invasion. Other advantages of ready-made doors do not. But there are a couple of drawbacks. Firstly, they are not always suitable for a specific opening, then it will have to step up (to make a screed) or vice versa - to increase (to break the wall), and this may affect the reliability of the entire construction and not for the better. Secondly, not every manufacturer will give accurate information about the design of the finished door. The main plus of manufacturing doors in order - an exact match the size of the aperture and the dimensions of the door, and, consequently, a higher degree of reliability. It is possible to accurately determine and design, and kitting, and design. In other words, order something that will fully satisfy you. True, the terms of manufacturing such a door - from 5 days to two weeks. Q: Which version of the door opening is preferable from a security perspective: inside or outside? Answer: The door, no matter how "cool" it may be, should not open inside the room and outside. Otherwise, it can be squeezed without noise standard 5-ton jack. If the door opens outward, then even the most careful attempts to nothing lead. In the "best" case, pulling the door on himself, the thief will tear off the handle and grips will not be for nothing. Q: What is the construction of a metal door more secure? A: Usually a metal door frame made of steel tube of rectangular or square. There are 2 main options: one - welded pipe 50x50 mm from the corner, the other - from the final profile of a rectangular 30x50 mm. From the "corner" stronger, more reliable and more expensive on average by 50 percent. To improve the reliability of the design framework can be strengthened ribs of a similar profile. The frequency of such a "lattice" depends on the size of the door. The frame is sheathed with steel plates of different thickness: from 1,5 to 3 mm. Experts recommend using thick sheets at least 2 mm. Domestic producers tend to prefer the 2,5 - or 3-mm steel. How many pages should be - one or two - a question relative. If an armed attack on an apartment is not expected, in principle, you can do one, thick. While a thief will blow over it, the police have time to call. Another question is whether the lopsidedness of it: one sheet does not provide sufficient rigidity, and shrinkage in our homes can last up to 10 years if the lock gets stuck - the consequences can be sad. Between steel plates remained empty space that must be filled with something, otherwise the door will turn into a rattle, but nothing of the sound insulation will be forgotten forever. Requirements for the filler is not as critical, if the customer does not remove the old door. As a filler used foam, pine timber and the so-called "backing". Foam and pine beams are almost equal in their sound quality, but less environmentally friendly foam. "Filling" - a convenient and eco-friendly material, but unskilled work can ruin the castle - these cases were. In recent years become a popular filler mineral wool, which is ideal for its ecological properties, moreover, provides a very decent heat and sound, does not support combustion and very low heat. Q: What should be the hinge on the security doors? Answer: The number of loops depends on the weight of the door. Two loops is sufficient for doors weighing up to 70 kg. For doors weighing over 70 kg is recommended to use 3 hinges. Two steel sheet 2,5 mm make the door very hard, but if the loop is designed correctly, it can easily cope with even a child. The design of the loop, too, can be different. Standard loop consists of two parts. One of them has a pin, and another - "hood", which this pin is worn. It was such loops is completed, most doors. Over time, they become useless - are erased, the weight of a considerable one. Therefore it is better to put the loop "with the ball." The ball is in them between the pin and the bottom "cap". Because of this sliding friction is replaced by rolling friction. It turns out that something like a bearing. Such a loop requires less lubrication, no squeaks, is much longer. Q: Do I need protection from the cutting loop intruder? Answer: Indeed, one way of opening the steel door - cutting loops. To protect against this commonly used locking system "crab": a 3 - or 4-way locking system (up / down, left or right). They are mounted on the door from the side opposite the castle. When closing the pins enter the socket frame and fix the door. One - lever, the second - cylinder or Glow. This is done to make life difficult for the attacker. If you are installing locks of one type, be sure that they are different manufacturers. Its main advantage is simplicity and reliability. So, until it finds the robber, and sawing, it is possible to have time to call the police or to prepare for a rewarding meeting. There's another positive thing. In the event of a fire door, which was closed for only one latch is always easily opened from the inside. Can not be said about locks, because of the high temperature of their internal mechanism breaks down (stop working all spring elements) and jams - a door turns into an impassable hurdle. Structurally the heck are mortise and overhead, with lock and without it. If the attachment is done correctly, then use the difference between the invoice and the mortise is practically non-existent.

The first - when using a rotating door handle (or an additional key) put forward all deadbolts door bolt, and then blocked the main key. Second - when the extension and deadbolt lock mechanism made only one key. In this case, the entire burden falls on the part of the lock code, which reduces its lifetime. A further problem can be solved in another way: by protivosemnyh pins. They are mounted on the door from the side opposite the castle. When closing the pins enter the socket frame and fix the door. Question: How many locks should be in protective doors? Answer: Experts believe that the locks should be at least two, preferably - different systems. One - lever, the second - cylinder or Glow. This is done to make life difficult for the attacker. He will have to use more tools (unless, of course, for some reason there is no "Bulgarian"), and hence the probability of success will plummet. Of course, you can put both of the castle complex systems. But financially it's unprofitable, and that's advised to combine: the "peaceful" time of day to use the lock easier and sophisticated - at night or when nobody is home. If you are installing locks of one type, be sure that they are different manufacturers. In any case not be placed on a steel door locking latch. He can play with you a cruel joke - clicks at the most inopportune moment. Think about it better "before" and not "after" - a trash can and slippers in front of lovingly selected a door, but not on the side ... Question: How to choose the door locks? Answer: Acquire locks only in specialty stores where the salespeople or consultants can thoroughly answer all your questions. Decide with the class of the stability of the castle to criminal influences. GOST 5089-97 recommends the following applications for locks of different classes: Class 1 - barns doors and interior doors in the apartments, 2 nd class - the doors to the apartments (resistance to dissection is not less than 5 min), third class - entrance doors to flats and other premises, with certain values ??(resistance to dissection is not less than 10 min), 4 th grade - entrance doors to flats and other premises with substantial value, or premises to be taken under protection (resistance to dissection not less than 30 min). Castles 2 - 4 classes are subject to mandatory certification, which guarantees their performance and reliability. Question: Can I change the lock instead of only its "bot"? Answer: This economical and less troublesome than installing the new lock. Q: What is the secret mechanisms of door locks "Abloy" differ from others? Answer: In their circular arrangements of secrecy role of code elements perform special discs coded slot. Without going into details, it should be noted that the disk mechanisms of secrecy, unlike the pin tumbler and plate, structurally more protected from spikes. Suffice it to say that the time to open a criminal picking widely used mechanisms such as secrecy "Abloy" (key semicircular shape) exceed 30 minutes. However, this type of lock has its own weakness: they do not resist cracking method collapses or drilling. The main ways to protect their mechanisms of drilling and folding are embedding in their hard-shell elements and the use of special pads. Q: Why is it necessary to pay attention to the metal of the lock made? Answer: When you lock to lock the gates and fence gates, garages, summer houses, etc. hozblokov structures and installations find out whether he intended to operate in the streets. Parts of the castle should be made of corrosion resistant materials or be protected against corrosion. For this reason, should not acquire lock, having parts from aluminum alloys. Question: Why experts are strongly advised to put on a good old metal door latch? Answer: Heck - a good thing and very practical. Its main advantage is simplicity and reliability. Latch can not open a master key, almost impossible to break (impact hammers will be distributed throughout the area of ??door), you can only cut off all the same "grinder." But it's too noisy, and at the heck is closed only if there is someone inside - is a dangerous "symptom" for the thief. So, until it finds the robber, and sawing, it is possible to have time to call the police or to prepare for a rewarding meeting. There's another positive thing. In the event of a fire door, which was closed for only one latch is always easily opened from the inside. Can not be said about locks, because of the high temperature of their internal mechanism breaks down (stop working all spring elements) and jams - a door turns into an impassable hurdle. Structurally the heck are mortise and overhead, with lock and without it. If the attachment is done correctly, then use the difference between the invoice and the mortise is practically non-existent. Lock is needed not so much on a possible abduction heck outside, and to the door tightly adhered to the door frame and does not vibrate. Sometimes it is very useful and a chain. True, given the considerable weight of a steel door, the requirements for the strength of its links and fasteners to an order of magnitude higher than for wooden doors. Question: How to choose eye protection for the doors? Answer: By choosing this subject (almost essential), you should decide that for you is more important: to have 180 degree vision to see the shoes on my feet the caller, or observe a smaller, but do not confuse the family to strangers (less distorted picture). Q: How do the locks, remote unlocking? Answer: Their operating principle is this: there is a "body of the castle" - that is the device locking / unlocks the door and a control unit, which recognizes the "key" and sends a signal to the lock to open. In this case the "key" can serve as a smart card, key chain, like a car alarm and a device point-memorial, and enter a code from the keyboard. Q: What is the door chain is the most secure? A: Today, a new variant of the "chain". She looks like a long metal hinges, slight widening at the base. One part is attached to the box, but the door is screwed a metal hook with a ball on the end. If you want to open the door to a safe distance, throws the noose on a stick with a ball that is easily included in the expansion at the base. When the door was ajar, the ball slides along a narrow place before the end of the loop and does not open the door. To let the visitor have to again close the door, tilt the loop and reopen. Question: Can a metal door during a fire to deform so that does not appear to become an insurmountable obstacle in the way of evacuating people? Answer: The advantage of certified steel door that her painting is not deformed in the direction of "parts of the world" (up / north / down south, left / east, right / west). Deformation is allowed only inside and outside (ie the door can "swell bubble" or concave inward), which should in no way affect your ability to open it. Moreover, for the immediate evacuation of the fire door fitted with quick opening system, which is called - "panic". The gist is that if the outside to open the door only key, then the inside, all locks opened at the touch of a door knob. Sometimes a pen in appearance resembles rail, almost equal to the width of the door leaf. It is fastened to the door with a flexible arm. Some fire doors has a special sensor that the sudden increase in temperature gives the command to the built-specific mechanism, after which the door is locked, automatically blocking the path of the fire and smoke. However, in this case provides the ability to easily (without key) to open the door from the inside. Fire protection question: What is the effectiveness of autonomous smoke fire detector? Answer: They stand out among the means of active fire protection because they can react to smoke at an early stage of fire and can sound an alarm in time to warn people about the threat of fire.
