The page is devoted to issues of design, installation and Maintenance security systems. In the near future, we plan to introduce our potential customers to specific technical solutions on this topic.
One of the most important tasks in the field of security in Russia is to ensure safety in industries and facilities with increased fire and explosion hazards, including terrorist hazards.
One of the components of administrative, organizational and technical measures to solve this problem is the implementation at such facilities automated systems access of personnel not only to the dangerous enterprises themselves, which, however, is to one degree or another decided from the very moment such objects appear, but also of the personnel themselves to dangerous premises inside such enterprises.
The basis for the protection of dangerous objects is the concept of layered or zonal defense. On dangerous enterprise thousands and even tens of thousands of people can work. All of them have the right to pass through the checkpoint in the outer perimeter. However, only hundreds have access to dangerous buildings technological installations. And only a few dozen people have the right of access to security-critical technological process premises.
At the same time, the access procedure itself consists of a number of requirements that make it difficult for unauthorized access, and most importantly, exclude accidental or intentional sabotage on the part of authorized personnel.
In hazardous industries, the equipment of access control and management systems is often subject to specific requirements, for example, the requirement of explosion protection.
It is precisely for such explosive premises that our company has developed and began mass production of remote-controlled locking devices - the most reliable electromagnetic locks in operation. explosion-proof version, products that until now were not available on Russian market explosion-proof equipment. Electromagnetic locks are locking devices highest degree reliability, since they do not have mechanically wearing parts. They are guaranteed to block doors from unauthorized access to dangerous premises, since they contain built-in sensors for detecting door blocking.
The locks are very easy to connect to any access control system and do not require any adjustments during operation.
Electromagnetic locks have passed certification tests and are found suitable for use in hazardous areas, as well as in mines, mines and other facilities that have been assigned the appropriate explosion hazard category.
The products are intended for use in facility security systems, fire and security and fire alarm system as an explosion-proof controlled actuator locking device. Burglary resistance class U3 according to GOST R 52582-2006. Used to lock doors, gates and other blocking devices.
Two types of explosion-proof electromagnetic locks have been developed and put into mass production: AL-MAL-FE and AL-MAL-FL.
The AL-MAL-FE lock is installed in rooms hazardous due to firedamp and dust, as well as in indoor and outdoor installations with a gas environment of explosive zones of classes 1 and 2 in accordance with GOST R 51330, PUE ch. 7.3, and has explosion protection marking РВ ExsI X/1ExsIICT5 X/Ex maD 21 T80°C X.
The AL-MAL-FL lock is installed in indoor and outdoor installations, gas and dust hazardous zones of classes 1 and 2 in accordance with GOST R 51330, PUE ch. 7.3 and has explosion protection marking 1ExmaIIT4 X/Ex maD 21 Т80°С Х.
It has a built-in lock status control with a relay output based on a Hall sensor.
Both types of electromagnetic locks come with an attached cable and cable glands different designs:
■ for open laying of the connected cable;
■ for laying the connected cable in a pipe;
■ for laying the connected cable in a metal hose;
■ with attached armored cable.
The length of the connected cable is determined by the customer's requirement.
COMPETITIVE ADVANTAGES:
■ have no analogues on the Russian market of explosion-proof equipment;
