Installation and commissioning


In accordance with current legislation, the installation of an access blocking system should be performed by trained technical staff based on compliance with the manufacturer’s instructions. Where possible, when installing an access blocking system it is aimed that the equipment will be mounted so that during the process of service-maintenance of the system, access to equipment will be easy.

In the case of outdoor turnstiles – they are installed in a foundation buried at a specified depth depending on the characteristics of the turnstile (height, length, aperture). For turnstiles mounted on the outside, a great importance is given to IP protection class for housing and electrical circuits, environmental conditions are an important factor in terms of the system’s optimum operation – on medium and long term.

Interior turnstiles are attached in floor level bolts, prior to this, installation finishes being required. In most cases, standard fixing materials are delivered with the turnstile.

Auto barriers will require a robust and stable attachment, for this in the foundation it is added a layer of cement. Depending on the application and the equipment used there are cases where the barriers are attached in bolts on the finished floor level. For application that are provided with wider entrances, barriers can be mounted face to face, in the master / slave system. Thus they can cover very wide entrances specific to industrial sites or loading-unloading platforms.

On retractable poles, the depth of the pit in which they are “mounted”- is done according to the snare that is made by the retractable cylinder. With this equipments, a special attention must be given to the total protection against atmospheric agents, reliability, high resistance to shocks and extreme temperatures.

The commissioning of the access blocking system is done in the presence of the system’s beneficiary, in proper compliance with the requirements expressed by him. The beneficiary is instructed about how to use the system and receives a number of specific documents – according the legislation.

Roel Systems formed teams of certified installers, teams that are supervised by engineers with experience in the field.

The components of an access control system

The access control station (or controller) is the central device that connects all field equipments ( card readers , buttons , electromagnets or bolts / electromagnetic locks , extension modules , keypads , sirens , etc.). Also the controller is the device that manages information from the readers (proximity , biometrics, barcode etc.) and commands the mechanical locking elements (electromagnets , locks / electromagnetic locks , turnstiles , gates etc.).

The readers ( of cards , biometrics,of barcodes etc.) are field elements that are accessed by users for them to be checked. They transmit data to the controller that will compare whether the user is registered in the database and can access the objective. If the controller decides that the user is registered in the database with access in that objective, that will activate the mechanical locking element ( electromagnet, locks / electromagnetic locks , turnstile, gate , etc.) , and access will be allowed.

Proximity card readers

are the most commonly used access readers used at this moment. The proximity reader is composed of an antenna and a control unit which converts the signals recieved from the proximity card into the specific communication protocol( Wiegand , RS232, RS485 etc.).

Advantages: the proximity readers are easy to use, the user is only required the proximity card. It provides high speed data transfer to the controller.
Disadvantages: the proximity readers can be easily fooled by a user who stole a valid card .

Biometric Readers - ( fingerprint, hand geometry , face recognition , iris recognition , etc.)

it recognizes the unique biological characteristics of users. The need to install a biometric reader in general appears to objectives that require a high degree of security

Advantages: it can not be fooled by unauthorized persons ( as can happen by finding a code or finding a proximity card ) .
Disadvantages: higher implementation costs compared to other technologies, longer time for verification and recognition.

The mechanic locking elements ( locks / electromagnetic locks , electromagnets , turnstiles , gates etc. ) - provides the mechanical blocking of access roads until thei receive the order of release from the controller after user authentication . The mechanical locking elements can be comanded to open the fire detection systems when it signals a fire alarm .


They are " fail safe " locks that need fueling in order to produce the electromagnetic field and lock the door.


Provides the mechanical blocking of access roads .

Emergency buttons are installed inside a controlled space and can be used during the time when the access control systems are not in service , or they have technical problems .

The buttons are mandatory installed on every controlled door .

Centralization and management equipments are personal computers / servers with access control softwares that manages the access control system, the users and the system functions .

Some programs have also a timekeeping software.
