Alarm security system or double door

Categories: Doors, Locks

According to most experts in the industry, the alarm security system (SOT) in Bulgaria is absolutely meaningless.

In practice, this technique has only a demonstrative character. The door stickers that have a SOT will not deny any professional thief, but will just warn him what to expect.

It would be much more treacherous if the SOT did not play and was quiet, but connected with the headquarters of the company or with the police. So the thief can be surprised and captured.

Another big disadvantage of SOT in Bulgaria is that the company’s employees do not have direct access to the secured premises. Security guards can stand in front of the building or apartment, and thieves act at will.

Therefore, the more familiar prefer to have two entrance doors to the apartment instead of a security system. Here you have to be very careful, because a huge part of the so- armored doors are not armored at all. When opening the first door, a powerful alarm siren can be triggered. It should not, however, be placed over the door, as most people do, but in an inaccessible place.

It is very important that these locks are mounted so that the door opens with a certain unlocking sequence. For example, first turn, but once, not twice the secret lock, then twice, but in the opposite direction, the cartridge. If the sequence or the number of revolutions go wrong, the door is blocked. It sounds complicated, but it can be done by almost every master who mounts locks.
