Electronic devices for the protection of housing: overview of the three models of "Invisible locks" of domestic and imported production
It is no secret that with the growth of housing security with the simultaneous technical complication of the castles is growing and professionalism of hackers. Who will give a worthy repulse robbers? According to experts, one of the most effective measures of "defense" of our apartments is a steel door equipped with an electronic "invisible lock". What it is?
Unlike the usual mechanical locks, the "invisible" either do not detect themselves from the outside of the door, or create active interference hacking and therefore become a mystery to the thief. For example, consider three devices.
1. Mortise Electrical Castle E-Volution (Cisa, Italy). Its shut-off riggers are driven by a miniature electric motor located in the castle housing. The performance of the lock when the network voltage disappears is provided by a battery hidden inside the door of the door.
The door is open using an electronic transponder key. It must be reduced to the reading zone and the lock in the door will automatically bother himself (hip-set situations you can use a highly reliable cylinder key). From the inside it is opened using the control buttons available on the internal lining.
Lock the door is even easier: slamming- and at the same time the mechanism of riglel extensions is automatically operated. If the automation has given a failure, the sound and light signals are triggered.
But the most important thing, when trying to unauthorized opening, the lock can send a domestic alarm or even a private protection system.
The dimensions of E-Volution are similar to the size of the standard CISA locks, which ensures the possibility of replacement. Price, from 13 thousand rubles.

1-2. The reading device in the E-Volution lock is mounted in a special bron alphabet that protects the cylinder lock from the outside of the door. The dispenser is 1.5 cm.
2. Patch Electromechanical Castle "Polis 11mN" ("Vitek", Russia), not having external signs of installation (key well). It is assembled as an additional locking device on steel doors (as well as gates and wickets) from the inside.
Outside the lock opens only when the key-block key is made by the EM-MARINE key to a hiddenly mounted reader (anti-vandal performance). From within the direction of the rotating handle on the lock case. It feeds the lock through the adapter 220 / 12B. The compartment also includes a control unit and an uninterruptible power supply unit with a battery. It is important that energy is spent by the device only in the process of opening to "stroke" from the spot of spring-loaded riglel, it is manually installed, using the so-called platoon cam. Price, from 3500 rub.

When installing the lock "Polis 11mn" (4) on the door, the contact device for the Krone element is hidden (5). It allows you to apply (outside!) Necessary for opening the lock using a keychain key (6) power supply, even in the case when the mains voltage is missing, and the batteries are completely discharged.
3. Invisible Castle "Fort" ("Yuni Fort", Russia) without external signs of installation. This is also an electromechanical overlap latch with a manual platoon of the springs of the locking beegel, installed on the entrance door from the side of the apartment. Price, from 14 thousand rubles.
The device has two independent opening systems. Main System: The lock is unlocked by a miniature infrared keychard, the owner of the lock itself installs its code and can change the combination for 15-20s.
Backup System: With a call button, the four-bit decimal code is gaining, which the host writes in advance in the memory of the electronic unit.
The lock is protected from the selection of code in both opening systems. For example, after the tenth incorrect IR code, it is blocked by 7.5 mim, and simultaneously the siren sounds during 15. With subsequent attempts to select the code, the blocking time duration doubles.
Akak get into the house if the mains voltage turned off, and the batteries were discharged? Remove the call button (included in the kit) and connects the "Crown" battery to its contacts. After 2-3c, the device charges so much that the lock can be opened.

In the electronic unit (7) of the Fort lock (8) there are a 12V network adapter, a built-in backup power supply (3 AA batteries), a call, siren, a main (infrared) and backup (button) of the opening channels (9).
