There are many reasons to switch from traditional mechanical fasteners to electronic fasteners. The Electronic Access Solutions (EAS) provide better security, greater comfort, excellent integration with existing electronic systems and a design that greatly appeals to end users.
In the last ten years, electromagnetic locks, also known as maglocks, are used more and more, and although there is definitely a use for them in the market, they also have their limitations and, in some cases, should not be used at all.
Electromechanical locks have a wide range of use where there are fast blocking and operational demands. Electromechanical locks can be used in both light and heavy interior doors, exterior doors and also in fire protection doors.
Since the operation of the electromagnetic locks depends exclusively on the passage or interruption of the electric current, these locks can be integrated very easily in any access control system (manual with a simple pushbutton, or automatic with any type of recognition system). Electronic card, pupil, fingerprint, etc.), home automation systems, alarms, etc.
This type of locks is common indoors that need to be closed securely and with limited access, but at the same time with high traffic, for example, office buildings, restricted areas in public access centers, etc.
These electronic door locks can be controlled by a variety of electrical pulse generating equipment. For example, access control systems, keyboard, card reader, and timer. The locks have sensors with the following monitoring outputs: the position of the bolt, handle down, request to exit, the status of the door. The locks can always be opened mechanically through a cylinder or turn to the right. Electromechanical locks can also be used on doors with the fire rating.
The models with split spindle function have an electronically controlled external handle, while the lock can always be opened from the inside of the handle. This requires a split shaft handle. The locks can always be opened mechanically by the cylinder. These electronic locks are locked automatically when the door is closed. The split spindle function allows more convenient use due to the lack of need for a button to exit.
In these models, the inner and outer handles are controlled electronically. The locks can always be opened mechanically by a cylinder or clockwise rotation. These electronic door locks are suitable when there is a demand for extended door control since they can have access control both at the entrance and at the exit.
Double Acting Bolt
The models with double action bolt are suitable for use when the door requires a push or pull operation. These electronic locks can be used in conjunction with an automatic swing door operator.
Maglocks are easy to install economically with a ZL or L bracket on most aluminum or wood doors, as well as steel doors. It is not necessary to cut in the aluminum where under normal circumstances specialized tools and a good amount of dexterity are needed to adjust to an electrical mechanical block, which most installers do not have, so they fit a maglock regardless of whether it is suitable for the application or not. The basic empirical rule is not to fit into a maglock in which the wiring is exposed.
There are several differences between a maglock and an electric bolt. However, one of the major differences is the fact that an electrical block operates in a normally open electrical circuit, where the magnetic block operates in a normally closed circuit.
What this means is that there is no power for an electrical lock and only when the release button is pressed or the system is activated in another way, the circuit closes and the power pulse of the electric lock allows the cylinder to release the bolt and the lock opens suddenly. Therefore, if there is a power cut, the lock remains closed and can only be opened manually with a key.
A maglock must be on all the time to remain closed and, as soon as a power cut occurs, it will open automatically. In the same way, if the maglock cable is not hidden, it can be cut and the door/gate opened. If the power of an electric lock is cut off, the door/gate remains closed. This is one of the biggest disadvantages of a magnetic block.
The electromechanical access control systems offer several advantages over traditional locks and keys.
- Smart keys cannot be duplicated
- Electronic locks do not have a keyway that can be picked up or hit
- Keys can be deactivated if they are lost or stolen
- Both lock access and key registry access and access to events denied to memory
- The keys can be programmed according to the time, date and level of authority, so only authorized users can get access
These electromechanical systems generally have four main components: electronic locks, smart keys, discharge devices and administration software. Each of these components provides specific functionality within the system to increase safety and responsibility.
Electronic cylinders replace standard mechanical cylinders and do not require wiring, power or batteries. Locks store all access events in memory, both granted and denied, and can be interrogated in case of loss or theft of a key. The standard features integrated into these cylinders include:
- Without removable keyway
- Resistance to manipulation
- Torsion resistance
- Resistance to stunning
- Double-key entry or time delay
The smart keys store the access control permissions of the user, as well as the information about the locks to which the user has accessed or to which he has tried to access.
The discharge devices act as the conduit between the smart keys and the management software. These ‘communicators’ re-authorize the permission schedule of the smart key while simultaneously downloading recorded events from the key’s memory and transfer all the information to the database on your computer.
Finally, the management software is the intelligence that drives the entire system. Software packages offer a wide range of management tools to adapt to any type of installation, from small single-location companies to multinational corporations.
