High-Speed Gate Operator and Access Control Upgrade in Atlanta, GA

This project focused on rehabilitating existing gate infrastructure while upgrading key components to improve performance, speed, and overall reliability across the property..

The scope included restoring two 13-foot V-track gates and replacing outdated entry hardware with modern, high-performance operators and advanced vehicle detection systems. Rather than a full replacement, this project was designed to extend the life of existing assets while bringing the system up to current standards for a commercial access control system.

Work began with gate refurbishment to improve both appearance and durability. Each gate received a full black semi-gloss spray treatment, restoring its finish while adding protection against corrosion and long-term wear. This step not only improves aesthetics but also helps preserve the structural integrity of the gates over time.

The operator systems were then upgraded by replacing the existing DKS 9150 units with All-O-Matic SL-100DC Pro slide gate operators. These high-performance units are designed for smoother operation and increased efficiency, making them a strong fit for high-traffic environments. To meet the client’s request for faster operation, the pulley system was custom-calibrated and reversed, allowing the gates to achieve an opening and closing speed of 12 inches per second.

Barrier arms were also upgraded as part of the overall traffic flow improvement. Existing DKS 1601 barrier arms were replaced with All-O-Matic Magna-Q units, which were synchronized with the slide gates to ensure coordinated movement. This creates a more controlled and efficient entry and exit process, especially in properties with consistent vehicle traffic.

A major portion of the project focused on upgrading detection and safety systems to meet current UL 325 compliance standards. AES yellow disc e-Loops were installed, including one dedicated loop for free exit and two safety loops to prevent accidental gate closure—one for each gate. These systems provide reliable vehicle detection without the need for invasive installation methods.

Additional detection enhancements included the installation of Optex vehicle sensors, including virtual loops and presence sensors mounted on specialized mini-posts. These components provide precise triggering for gate closure while improving overall system responsiveness.

To meet modern safety requirements, EMX IRB-MON2 monitored photo-eye sensors were installed with protective hoods. These sensors ensure the gate system can detect obstructions and respond immediately, helping prevent accidents and maintaining compliance with current access control safety standards.

Existing infrastructure was also addressed where needed. Resident arming loops that had deteriorated due to failed caulking were removed and reinstalled, protecting exposed wiring from weather damage and restoring proper functionality.



As part of the access control transition, the outdated DKS 1835 call box and cellular hardware were decommissioned and replaced with a modern EMC system. This upgrade provides improved resident access control and supports remote management capabilities, aligning the system with current expectations for Atlanta access control systems.
