commercial door access control systems

There has been a dramatic shift in the design of commercial access control systems due to the growing importance of safety in today’s dynamic global community. We are now in the digital age, where complex commercial access control systems are essential, and we are no longer dependent on the traditional approach of using a lock and key. These systems by Security in DFW not only safeguard property but also serve as vital amenities in attracting top-tier tenants. With the ability to remotely manage multiple buildings, they offer unparalleled convenience and efficiency. As technology continues to progress, the importance of robust access control solutions only intensifies in safeguarding assets and ensuring peace of mind in an increasingly complex world.

Types of Commercial Access Control Systems for Doors 

There is a wide range of access control door lock systems available at Security in DFW, each with a unique set of features and functionalities that are tailored to meet the requirements of a particular business. We are going to delve into the different types of access control systems in this section, categorizing them according to their hosting, which can be cloud-based or on-premise, as well as the access method.

On-premise Systems

These systems are characterized by the fact that their servers and hardware are in the building itself. The maintenance and management of these systems typically require a dedicated IT staff, and they typically come with higher initial costs. One positive aspect of on-premise systems is that they allow for greater control over the security of data.

Cloud-based Systems

Cloud-based access control systems have been gaining popularity over the past few years. These systems store their data and management tools online. Easy scalability, remote access, and reduced initial costs are all made possible as a result of this. In addition, updates and security patches can be distributed automatically, which guarantees the highest possible level of security measures.

Components of Access Control Systems

When implementing access control door lock systems, it is important to take into account various supplementary components in addition to the access controller, which serves as the central processing unit of the system. Should the components be absent or in suboptimal operational state, it may lead to a substantial escalation in the total project expenses. In addition to the controller, an access control system consists of two essential components (lock and reader) and two discretionary components (DPI and REX).

The Lock

The lock ensures the door remains securely closed, and the system will temporarily disengage the lock in the event of a successful badge scan or if someone wishes to exit. Locks are available in various forms and dimensions, primarily classified as electrified strikes, electrified handles, maglocks, and crash bars. Maglocks, like certain other locks, necessitate a continuous power supply in order to remain locked and are commonly known as Normally Closed (NC) systems. The electric circuit remains connected, providing power to the magnets, and disconnects only when the door requires opening. Electrified strikes and handles typically operate in a Normally Open (NO) configuration, meaning they only require power when someone is entering or exiting the door. However, specific models offer the capability for an installer to switch them to the Normally Closed (NC) state using a hardware switch.

The Reader 

Card Readers are devices that are installed on a door or adjacent to it in order to obtain entry. The readers serve as the initial stage of the authentication procedure, capable of verifying credentials through card insertion, card swiping, or card vicinity. Reader examines identification documents, relaying the information to the access controller which will then analyze it and determine whether the individual is granted permission to enter or not. If authorization is given, the relay will be toggled (from normally closed to open or vice versa) for a brief duration to permit entry. Readers for access control door lock systems  vary in their physical characteristics, but they will utilize one of two widely recognized protocols to establish communication with the controller. 

Door Position Indicator (DPI)

The DPI, or Door Position Indicator, is an elective system component that enables the access controller to determine the status of a door, whether it is open or closed. In the absence of it, the controller can still verify and unlock doors, but it will not have the ability to detect if, for instance, a door is left ajar, thereby jeopardizing the overall security of the area. The image below illustrates that the DPI functions as a circuit, oscillating between a closed and open state, resembling a door contact sensor used in alarm systems. Certain access control systems have the capability to notify an administrator if a door remains open for a specific duration, and this functionality relies on the presence of a Deep Packet Inspection (DPI) system. Some maglocks have an integrated DPI element and are commonly known as “monitored maglocks.”

Request to Exit (REX)

The REX enables an individual to exit a door that is controlled by access restrictions. It can be either a tangible button or an infrared sensor positioned above the door. The REX is regarded as an elective element due to the fact that specific locks enable “manual egress,” wherein the user’s act of pushing the handle from the inside is sufficient to open the door without requiring the involvement of the access controller. This situation bears a strong resemblance to that of a hotel room, wherein a user is required to use a badge to gain entry, but existing is simply a matter of exerting force on the handle. 

Although not mandatory, it is advisable to use REXes (Request to Exit devices) as certain access control systems rely on this information to generate reports regarding Door Forced Open events. In the absence of a Remote Execution (REX) mechanism, such as a Passive Infrared (PIR) sensor, the commercial access control system for doors would lack the ability to distinguish between an unauthorized intrusion attempt and a person who genuinely intends to exit through manual means. Door Forced Open alerts are crucial not only in the event of someone attempting to forcefully open the door, but also if they tamper with the lock and subsequently return at a later time to gain access to the door (for example, by taping the latch to prevent it from engaging).

Thus far, we have delineated a conventional access control system, in which the various components are interconnected to a door controller via low-voltage electrical cables. Nevertheless, there are instances where wiring specific doors proves to be exceedingly challenging due to constraints such as graded buildings or aesthetic considerations, as well as the exorbitant expenses associated with cabling. Under those circumstances, it may be prudent to install wireless locks that incorporate the reader and, if desired, the DPI & REX, directly within the handle.

Conclusion 

Ultimately, the selection of an appropriate commercial access control system is crucial in order to effectively adjust to the contemporary, adaptable work environment that has arisen. To guarantee a secure and user-friendly experience for employees, property managers, and visitors, it is important to give priority to features such as remote access management, smooth visitor handling, and advanced authentication methods. An effectively implemented access control system not only enhances security but also improves the overall attractiveness and value of your commercial property.

The effectiveness of an access control system is heavily dependent on the correct installation and integration.
